			<description><![CDATA[<h4><strong>Roles, responsibilities, and policies have to be defined to manage     the risks of software installation. </strong></h4>
<p><span class="dropcap">A</span> new software installation is one of the most difficult challenges for an   organization. There are many considerations in managing the selection-purchase-implementation   of a modern system. Buying a new system or developing a program in-house carries   several risks that must be realized. Understanding the risks up front is the   first step to overcoming them. Here are several key steps to make sure your   project goes well.</p>
<p><strong>Custom or off the shelf?</strong> <br /> In the past, most companies had an information services (IS) department that     had a number of programmers who were able to slowly incorporate managers’ ideas     into an existing system to provide better reports. The system was completely     customized to meet the needs of the managers and unique to that specific     organization.</p>
<p>There are two primary concerns with these highly customized systems. First,   the hardware is becoming obsolete and there is a lack of replacement parts.   The second issue is that the computer language that the software was written   in is often no longer the preferred method. The old languages do not provide   the flexibility and strength that newer coding allows. Even if an organization   wants to stick with the old system, schools are not teaching the old languages   and it is difficult to find people to keep an old system running.</p>
<p>This dilemma leads organizations to a fork in the road. How do they go forward?   One way suggests they task the IS department to write a whole new program that   does everything they want it to do while keeping the existing system up and   running. Often the expense of system maintenance plus new system development   is too great. The second path is to scrap the old system and buy a commercial   off the shelf (COTS) solution. This path leads to many choices, new risks,   and integration issues with other packages. The fact is that there is no system   available that will do business exactly like an organization does it now.</p>
<p><strong>Minimizing risk</strong> <br /> Either choice is expensive and both have significant risks. Business leaders     of large organizations have to decide how to face this situation and minimize     the risk. Smaller organizations probably have no IS department and cannot     even consider the first path, so they have the risks of only the second path.</p>
<p>The path to a COTS package has obstacles, too, but there are a number of   ways to avoid those obstacles. Begin with a detailed needs statement. This   statement will help guide other decisions.</p>
<p>If an organization has most of its internal processes detailed in standard   operating procedures (SOPs) or detailed work instructions, the first hurdle   to a COTS selection has already been eliminated. However, experience shows   that only 20-25 percent of businesses have this level of detail prepared in   advance.</p>
<p>If there are no SOPs, a plan needs to be developed to document the roles   and responsibilities for each person who will be even remotely associated with   the software change. Do not shortcut the list. The time going back to revise   the list will be exponentially more expensive than doing it right in the first   place.</p>
<p><strong>Documenting roles, responsibilities, and policies</strong> <br /> For each person’s role, be sure to include everything that may be related   to the new software. See the accompanying section “<a href="#rolesend">Roles   and Responsibilities List</a>” for an example. <a name="rolestext"></a></p>
<p>The associated policies also must be collected and sorted. Policies are the   laws, regulations, and company rules. There may be guidelines or rules that   have been institutionalized and have been part of the program for years but   have no real value. These should be identified and considered for change in   the new system. All of these policies should be listed for each major area   of the business being affected. Collecting these three items will empower your   organization.</p>
<p>Collect the information and display the information in small workgroups.   Let them review the bigger picture that goes on outside their individual roles   and responsibilities. Several positive things will occur.</p>
<p>First, coworkers will realize the connections and relationships their work   has in ways they have never seen. Second, they will likely identify some paths   of workflow that do not make sense. And finally, any errors in recording the   roles and responsibilities will be identified and a final edit of the documents   can be made.</p>
<p>Even if SOPs are completed, go through this procedure of reviewing the documented   processes. More than 90 percent of businesses operate outside their SOPs, usually   because the business rules, tools, or software does not help them get the job   done efficiently.</p>
<p><strong>Evaluate workflow<br /> </strong>Take some time with these workflow discrepancies. Find out why the   list is wrong or why the employees feel a workflow does not make sense.</p>
<p>Ask if there are any ideas on how to make a job easier. During a recent project   at a public transit authority, the opportunity was taken to identify what they   do, identify best practices for those processes, and implement as many of those   best practices as possible with the new software installation. In this case,   the COTS selection was to replace the maintenance and inventory system, which   had to interface with financial and HR/payroll systems. The organization decided   to research similar businesses to see how they performed maintenance and inventory   management and found 15 best practices that they wanted to install as soon   as possible.</p>
<p>The best practice research was an up-front expense to the process, but it   offered some surprises. Using the best practices resulted in a multimillion   dollar return on their investment. The research also identified frustrated   business leaders from the research group itself who were interested in making   similar improvements. The return on investment paid for more than half the   cost of professional services and the entire cost of the system purchase.</p>
<p>Taking this process seriously can pay off. The risk is to underestimate the   importance of knowing, reviewing, and improving the processes. If these steps   are not completed in advance of the installation, the software vendors who   typically charge for these services will have to do the research to find the   same answers.</p>
<p><strong>Starting ahead</strong> <br /> One of the primary risks in implementing a COTS package is that the software     may dictate certain processes. Consider the following example. The normal     process for adjusting maintenance technicians’ payroll issues at one     company is to wait until all employees have entered their times in the system     and then make adjustments to any exceptions on the last Wednesday of each     month before the monthly payroll is sent out.</p>
<p>The COTS system selected allows for adjustments for only three days after   each person enters his data. The business processes were never reviewed in   advance and, when the vendor came in and demonstrated all the new features,   no one thought to ask about the time sheet exception process. Suddenly, the   organization is sitting on a huge investment that either cannot be used or   is so painful to use, everyone hates it. Does this sound familiar?</p>
<p>Every software vendor has a closet of skeletons. The closet has a list of   past sales that were implemented poorly for multiple reasons. When this happens,   employees have to work in frustration and likely have dual processes going   on to get the job done. It is common to find organizations doing the same process   twice—usually electronically and an identical paper trail—to make   sure everything is complete. This is a big opportunity for organizations to   streamline operations and get the job done right the first time.</p>
<p>Once you have made the full list of roles, responsibilities, and department   policies, develop high-level workflows for major tasks. Ask potential COTS   vendors for a similar list of how the business will operate with their system.   A common response will be that the system’s flexibility will allow you   to configure the system in so many ways that they cannot give you that list.   Insist on the list even if it has to resemble their best client’s site.   With the two lists, differences can be analyzed.</p>
<p><strong>Software selection</strong> <br /> When the processes have been identified and the quality assurance is completed,     the next step is to select software that fits the work as closely as possible.     The term “as closely as possible” is used because there is not     a perfect match from an organization’s model (the roles and responsibilities     lists coupled with the policies) to any software. Vendors are designing COTS     to fit specific niche markets but there will always be some percent of an     organization’s model left out of the proposed system.</p>
<p>The “<a href="#currentend">Current vs Proposed Processes</a>” diagram   shows an example of current processes and a proposed process by a vendor. <a name="currenttext"></a>In   this oversimplified example of how payroll works, two processes are lined up   side by side to reveal similarities and discrepancies; the discrepancies are   highlighted in green. These highlighted processes are examples of discrepancies   that an educated buyer of a COTS system will know about in advance of the final   purchase.</p>
<p>The two examples also demonstrate how a discrepancy may not be a bad thing.   The first highlight shows how time cards used to be typed in manually and now   through the automation of scanning the time cards can be scanned in automatically.   This change will likely be considered a preferred cost-saving process. The   second highlighted example is the exception report. This exception report within   the current process is conducted monthly. Perhaps the supervisors only have   time to do it once a month due to some internal business rule. The proposed   process shows the report running weekly. The business leaders of the company   will have to decide on how to handle the differences. The power is knowing   about these differences ahead of the purchase.</p>
<p>The next thing is to meet with the vendor representative and discuss the   undesired discrepancies. This may be an area within the software that has great   flexibility and modifying the report run times could be an easy fix. On the   other hand, this may not be an area of flexibility; the company will need to   decide whether to change processes or look for another software that better   meets its needs.</p>
<p><strong>Talk to users</strong> <br /> A smart step before installing a COTS package is to go to one of the sites     where this software has been installed and talk with the people who were     involved in the process from beginning to end. Asking questions will provide     a good idea of the product’s capabilities. Vendors will typically recommend     only the best sites where their product has been implemented so ask the tough     questions.</p>
<p>Remember, the issues in a successful installation are only a fraction of   the issues in a bad installation. See the section “<a href="#sitevisitend">Site   Visit Topics</a>” for issues that should be explored when talking with   current users.<a name="sitevisittext"></a></p>
<p>There are cases where the buyer made the installation more difficult than   necessary. Software capability is not usually the cause of poor installations.   Take the advice of the software vendor coupled with the advice from the on-site   visit and make a plan to install the COTS system with the very best effort.</p>
<p>If the company is short staffed or short on employees who can think out of   the box to get this done the right way, seek out contractors who have real-world   experience. The most expensive thing is to shortcut the process and face a   failed implementation.</p>
<p><strong>Have a change management plan</strong> <br /> Remember that adjusting processes to meet the COTS solution should be well     planned. No COTS solution can do everything the way a business currently     does. There will have to be changes; with these changes there will be resistance.     Having a strong change management plan is crucial.</p>
<p>With few exceptions, the most important assets of a company are its people.   These critical assets are usually the most neglected during the installation   if appropriate change management steps are not in place from the beginning.   Managing attitudes and frustrations will accelerate the installation and overall   success.</p>
<p>One of the most important lessons in managing change is getting employees   accustomed to the concept that new ideas will be tested and some will fail.   Failed attempts will be discarded and new ones will replace those left behind.   Every opportunity to make people’s jobs easier should be incorporated.   Gaining this buy-in will pay off as new roles and responsibilities are assigned   with the installation of the new system.</p>
<p>As long as critical policies and regulations are followed, roles and responsibilities   can shift to meet the new technology. Change management should be simple and   easy to understand. If the organizational change management plan does not include   assistance to ground floor supervisors and leads, review other plans. These   lower tiered leaders will face the bulk of the attitude adjustments and will   need real tools they can use to make positive changes.</p>
<p>Many organizations are looking to improve their business with new software.   Taking these steps of mapping out how business is done and how the new software   will help get to the next level is critical to making sure the risk of a failed   implementation is dramatically reduced. Knowing and using these steps has saved   organizations millions of dollars. Skipping these steps has cost many businesses   the same amount while not achieving the desired result. <strong>MT</strong></p>

			<description><![CDATA[<p><span class="dropcap">U</span>sing specialized sensing technologies for machinery condition based monitoring   (CBM) or predictive maintenance (PdM) has long been documented as a beneficial   part of a machinery reliability strategy. According to MaintenanceBenchmarking.com,   world class companies often devote up to 50 percent of their entire maintenance   resources to condition based monitoring and the planned work that is required   as a result of the findings.</p>
<p>Although there are a number of technologies that should be part of any CBM   program, vibration analysis is the most predominant for maintaining and troubleshooting   rotating equipment. Vibration analysis resources on the web are hard to find   using search engines as all the commercial resources are getting top billing.   I have compiled some vibration resources on the Internet that range from full   blown online training to pages that include links to other vibration analysis   resources.</p>
<p><strong>Training resources</strong></p>
<p><a href="http://www.vibrationschool.com/">www.VibrationSchool.com</a> offers   vibration analysis training on the web so you can access the lessons on your   personal computer any time of the day or night. The site plans on offering   live, web-based, and instructor-led courses in 2004.</p>
<p>VibrationSchool.com also offers an active e-mail discussion forum that allows   you to share your experiences, ask questions, or simply sit back and read as   hundreds of your peers discuss many of the same issues you face and share solutions   that you can use.

			<title>Monday, 01 December 2003 15:03  -  Extending Pump Motor Life In Liquid Level Applications</title>
			<link>http://www.mt-online.com//index.php?option=com_content&amp;view=article&amp;id=1136:extending-pump-motor-life-in-liquid-level-applications&amp;catid=209:december2003&amp;directory=90</link>
			<description><![CDATA[<p><span class="dropcap">M</span>any process systems operate by the storage, transfer, metering, and disposal   of liquid materials. The pumps that move the liquid materials represent a point   where maintenance failure can halt all other processes. Extending the service   life of these critical process components can significantly reduce process   as well as maintenance costs.</p>
<p>Most often the decision to turn pumps on and off is based on the level of   a liquid in a storage vessel. Fig. 1 shows a simple single point float switch.   When the level of the liquid falls below the float switch, the pump motor is   turned on to bring the level high enough to open the switch and stop the pump.   This maintains a constant level.</p>
<p>(Safety note: Pump motor operating voltages such as 110/220 V ac should not   be run directly through liquid switches. Low voltage control signals should   be used to operate relays that switch the pump motors on and off.)</p>
<p>The <a name="Fig1text"></a><a href="#fig1">Fig. 1</a> application is well   suited to keeping a constant level and it is relatively low in cost and installation.   However, from a maintenance point of view, the pump motor is being run frequently   and for short periods. This provides for the greatest pump impeller and pump   motor bearing wear.</p>
<p>Also, from a process design perspective, the single point level control may   not provide the fluid turnover desired and could lead to a buildup of sludge   or other material.</p>
<p><a name="fig2text"></a><a href="#fig2">Fig. 2</a> illustrates an application   that uses two float switches. A high and low level can be selected that reduces   the wear on pumps and motors as well as insures a high level of liquid turnover.   In this application the pump turns on when the low level is detected and turns   off when the high level is detected.</p>
<p>In some critical applications an additional switch is installed to detect   a high level above the pump shutoff point. This can help prevent costly overflow   or spill conditions.</p>
<p>There are some applications where it is not possible to mount float switches   at the desired points in the vessel wall. For these situations float switches   can be suspended from the top of the storage vessel as shown in <a href="#fig1">Fig.   3</a>.<a name="fig3text"></a></p>
<p>For applications where the liquid material may foul a mechanical switch,   alternative sensing can be used. It is possible to mount a pressure sensor   at the bottom of the vessel as shown in <a href="#fig4">Fig. 4</a><a name="fig4text"></a>.   A control is needed to convert the pressure information into level information   and to program the high and low setpoints. An ultrasonic sensor also can be   used to determine the level of a liquid.</p>
<p>Regardless of whether the high and low setpoints are mechanically determined   or programmed into a control, they need to be selected with a view toward keeping   pump motors from the frequent start and stop cycles that accelerate wear, failure,   and consequently, maintenance. <strong>MT</strong></p>

			<title>Monday, 01 December 2003 13:16  -  The Medium Matters in Training</title>
			<link>http://www.mt-online.com//index.php?option=com_content&amp;view=article&amp;id=1125:the-medium-matters-in-training&amp;catid=209:december2003&amp;directory=90</link>
			<description><![CDATA[<h4><strong>While e-learning initiatives abound, traditional methods still form the core of training for maintenance personnel.</strong></h4>
<p><span class="dropcap">T</span>raining professionals generally agree that different people learn in different   ways, and the most effective training matches the delivery method with the   needs of each student. But whatever the method, the best technical training   encompasses four key factors: interaction, application, practice, and feedback.</p>
<p>At one time, it was thought that on-the-job training (OJT) offered the best   way for people in industry to learn a job and become really proficient through   practice under a watchful eye. But many of the veteran workers who were expected   to train newcomers either were not very good trainers—or did not want   to be. As a result, erroneous “tribal” information frequently was   passed down from generation to generation.</p>
<p>When new technologies come into the plant, OJT is often inadequate. Some type   of formal training is necessary to ensure that a plant gets the most from its   technology investment. For this, companies have developed a blend of instructor-led   training to impart essential technical information followed by hands-on workshops   designed to help students learn the skills needed to do a job.</p>
<p><strong>A variety of approaches</strong><br /> Still, this combination of personal instruction and     hands-on experience may not be the best way to present every subject, appropriate     for every circumstance,   or the most economical approach. Plant managers and maintenance supervisors   are seeking less costly ways to train as many employees as possible, and those   of us in the business of training continue to look for alternate solutions   to the ever-growing need in industry to upskill a downsized workforce for improved   job performance. Of course, the ultimate objective of industrial training must   be to enhance performance in the workplace.</p>
<p>With the advances in Internet technology, several training methods have evolved   in recent years that offer specific benefits for maintenance personnel. Let’s   take a look at what seems to work best with certain topics or for various types   of jobs and what employees can expect when they participate in an instructor-led   course emphasizing hands-on learning, take self-paced training using a CD,   take a course based on process simulation, or get training via the Internet.</p>
<p><strong>Instructor-led training</strong><br /> A maintenance engineer who just completed a 3-day class     commented, “I   learned more today than I ever imagined. If I had come here for this training   three years ago, I could have been doing a better job.” That’s   a typical reaction, because instructor-led technical training provides a special   learning opportunity that just does not exist elsewhere.</p>
<p>The highly qualified instructors, other experts, and facilities equipped for   hands-on training provide a unique environment for learning advanced maintenance   procedures and techniques. Students learn what it feels like to tear down and   set up control valves, configure field instruments, troubleshoot control loops,   etc., while receiving continuous feedback from the instructor. Many classes   can be packaged and shipped, allowing the training to take place at a customer’s   site or some other convenient location worldwide.</p>
<p>Among the compelling reasons to enroll employees in this type of training are   the wealth of application information available, the opportunity to learn and   practice essential skills, feedback from experts in the field, and interaction   with others doing the same kinds of jobs with other companies.</p>
<p>Of course, the instructors are the heart of this training. They must possess   a deep knowledge of their subjects and an ability to connect with classes.   It takes an exceptional individual to tailor presentations to the level of   the trainees in each class while making certain that all learn and understand   the material. Instructors sometimes must win over a reluctant participant or   tone down a “know-it-all” student without causing embarrassment.   However, persons attending these courses are generally very receptive because   they know it is important to their careers back home.</p>
<p><strong>Hands-on workshops</strong><br /> Jobs that require manual dexterity and good hand-eye coordination     are generally best learned through experience, including almost all mechanical     maintenance   and repair jobs. It seems easy enough to find a piece of equipment that is   not being used, and let people tear it down and put it back together.</p>
<p>However, once they get it apart, will they know where to look for signs of   wear or fatigue? How will they know what to fix on the inside? And will they   be able to figure out the tricks involved in getting a complex assembly back   together and functioning? Capable mechanics generally can do these things through   trial and error, but most manufacturers cannot spare the time for on-the-job   tinkering, and they cannot afford the possibility of an error causing a serious   production problem.</p>
<p>Training courses designed to teach the skills needed by maintenance personnel   must provide an opportunity for application of the information, practice, and   feedback. This requires making available all the components personnel will   encounter along with an instructor who can lead them through step-by-step procedures   and be there as they practice. This is true whether the components are mechanical,   i.e. valves, motors, pumps, etc., or electronic. Training equipment is continually   updated with newer models, and the necessary tools, test equipment, and software   also must be provided.</p>
<p><strong>eLearning</strong><br /> One of the newest approaches to training is eLearning, using the computer     as a means of conveying information to individuals and helping them learn.     Among   the characteristics of eLearning are speed of delivery; message timeliness,   accuracy, and consistency; and overall convenience, because the information   can be accessed at any time from nearly any place. Many people can be trained   at a relatively low unit cost without sending anyone away to attend a training   program.</p>
<p>eLearning can be applied to a variety of general subjects with broad applications   as well as specialized technical topics. Thus it can be used for management   and supervisor training as well as for operators and technicians. In many cases,   trainees can select specific topics from a menu, rather than having to take   an entire course. Students can refresh their memories by referring back to   the training materials at a later time.</p>
<p>eLearning methods include CD-based or self-paced training, distance learning,   simulations, and Internet-based training.</p>
<p>CDs are a very effective medium for teaching individuals how to use software   or to learn new versions of software with which they are already familiar.   They can be mass-produced inexpensively and are compatible with any computer   equipped with a CD-ROM drive. All the tools and resources necessary to learn   and use a new technology are provided, enabling trainees to make the most of   their training time. Sometimes whole classes can take self-paced training under   the guidance of a certified instructor, who answers questions, provides feedback,   and helps each student move ahead.</p>
<p>Distance learning involves establishing an interactive learning environment   between an instructor in one location and students gathered at a remote site.   In some cases, they communicate via simultaneous two-way video and speakerphone   hookups. Students and the instructor can see one another and engage in normal   classroom activities. Distance learning can be especially beneficial for crews   in remote locations, and when employees cannot leave the plant, distance learning   is a good alternative to classroom programs.</p>
<p>The use of computers to simulate plant conditions and events is a more promising   idea, and computer-based simulations for training on specific processes are   available. These tend to be in the area of operator training, where a number   of individuals must learn to interact with a process by observing a display   and using a keyboard and mouse to respond. Students can be exposed to a wide   range of conditions, including emergency situations, to which they must react,   and they can practice over and over until they learn how to respond quickly   to whatever the process throws at them. Simulations also may be useful for   maintenance personnel, especially for troubleshooting, but a hands-on element   must be added to enrich the learning experience.</p>
<p>Using the Internet for training may be the most promising advance in the realm   of eLearning. Internet-based instruction is not expected to replace currently   available training courses, but it will augment those offerings. It can be   an instant source of “help” information on a specific process or   type of equipment and can be especially useful to refresh individuals following   an in-depth course.</p>
<p>The Internet is a perfect medium for transmitting newly developed information   quickly to a widespread audience. This could include the latest engineering   information, technical advisories, or troubleshooting tips.</p>
<p>The online format also allows more interactivity than other forms of eLearning.   A person can communicate with an expert, ask a question, make a comment, or   even enter a chat room set up for individuals interested in a specific issue,   with the Internet serving as the medium for learning.</p>
<p><strong>Blending the methods</strong><br /> Internet-based training offers many benefits and can be     used to complement traditional instructor-led, hands-on classes, but eLearning     will never replace   the classroom experience.</p>
<p>One way to blend the best of the Internet with expert hands-on training would   be to create core courses of basic subject material and make them available   to the widest possible audience via the Internet. This could provide a uniform   foundation for individuals who later will pursue higher-level courses in the   classroom/workshop environment. <strong>MT</strong></p>

			<title>Monday, 01 December 2003 13:15  -  Professional Development: Alive and Well (or at least ...</title>
			<link>http://www.mt-online.com//index.php?option=com_content&amp;view=article&amp;id=1123:professional-development-alive-and-well-or-at-least-getting-better&amp;catid=209:december2003&amp;directory=90</link>
			<description><![CDATA[<p><span class="dropcap">D</span><strong>iagnosis:</strong> Among the victims of the economic slowdown over the past few years have been many professional development programs. Companies and individuals alike have been rather reluctant to “invest” (I believe PD is an investment, not an expense) significantly in training or educational opportunities.</p>
<p>While many of us would agree that this has often been shortsighted, we probably would also agree that limited finances require prudent controls and reduced cash outflow. Difficult decisions have to be made and perhaps we in the profession need to do a better job of helping companies and individuals understand the long-term value of developing the professional skills of our people and ourselves.</p>
<p>However, there is good news. This situation appears to be changing as the economy seems to be headed toward better times. And as the old adage suggests, “a rising tide floats all boats.” Thus, things are also looking better for the world of professional development.</p>
<p><strong>Conferences</strong>: Recently I attended the SMRP annual conference in Indianapolis. This year it had record attendance, essentially double what attendance was a few short years ago. These attendees were primarily practitioners looking for knowledge, information, networking—in other words, looking to develop their professional skills and stature.</p>
<p>There are several other conferences that are being planned and advertised by various entities for next year. Let’s hope that the attendance increase the SMRP conference experienced is also reflected in these other conferences. These are great places to quickly gather information and develop some excellent ideas to enhance your performance and that of your business.</p>
<p><strong>Certification:</strong> Just over 100 people took the SMRP Certifying Organization’s exam at the conference, attempting to become Certified Maintenance and Reliability Professionals (CMRP). To date more than 600 people have taken this exam. The successful ones who pass the exam gain recognition of their own personal professional development. And the unsuccessful ones learn of their areas that need improvement and can use that information to seek further training or education.</p>
<p>Exams such as this help us develop our capabilities by pushing us to excel and to succeed. Other certifications also exist throughout the industry and serve to push us forward toward professional excellence. Those who choose to participate in these types of certification programs improve their own capabilities and then are prepared to transfer those improvements into their businesses.</p>
<p><strong>Education:</strong> Those of you who have read my column before know that I am a strong proponent of having more university involvement in the maintenance and reliability field. Wes Hines from the University of Tennessee gave an excellent presentation at SMRP outlining current U.S. university participation as well as a comparison of the U.S. approach to that in other countries.</p>
<p>He also discussed the quickly growing and improving techniques of delivering educational programs to off-campus sites such as the student’s home or workplace. Watch for this area of education delivery to expand rapidly.</p>
<p><strong>Training:</strong> One of the things very obvious at the SMRP conference was the great number of companies offering training in the maintenance and reliability field. A number of exhibitors extolled their capabilities in providing both specialized and general training. Several of the presenters alluded to their internal and external training programs.</p>
<p>One needs only to look through the advertisements in this magazine to realize the diversity and number of offerings. Or, one can follow the various summaries of training opportunities that appear in this PDQ section each quarter.</p>
<p><strong>Prognosis:</strong> Professional Development programs appear to be gaining strength and growing stronger, following along with the economy. This is a great sign for the profession. Only as we as individuals, and as the maintenance and reliability field, continually develop ourselves in our professional lives will we truly become professionals.</p>
If we want maintenance and reliability to be included in the leadership of our businesses, we must achieve professional stature and be recognized for it. I believe that Professional Development in our field is alive, is getting better, and can “get well” if we all push forward by participating in the ways described above. <strong>MT</strong><br />]]></description>

			<title>Monday, 01 December 2003 12:31  -  The Reliability Paradox</title>
			<link>http://www.mt-online.com//index.php?option=com_content&amp;view=article&amp;id=1008:the-reliability-paradox&amp;catid=209:december2003&amp;directory=90</link>
			<description><![CDATA[<p><span class="dropcap">F</span>or the most part, we can describe in fairly exacting detail the functional   components of a strong reliability program. Moreover, we are confident that   implementing these reliability practices will yield results that benefit virtually   every aspect of our business (cost, quality, service, safety and environmental   performance, and capital turnover) and provide distinct competitive advantage.   However, we seldom see these reliability practices and results in an operating   plant. This is what I call the Reliability Paradox.</p>
<p>This is worse than the usual “knowing-doing” gap because of the   certain knowledge that implementation will bring a definite step improvement   in business results. It is almost as if reliability professionals are trying   to give away $100 bills, but for unknown reasons there are few takers.</p>
<p>It is a real paradox, and one that we must resolve.</p>
<p>We know what to do, we recognize the benefits, but we just do not practice   what we know. The question is why? Why is there such a large gap between knowing   and doing when it comes to reliability? Here are 10 reasons in increasing order   of importance:</p>
<p>10. “Sins of the past” take time to correct. In some plants the   impact of poor reliability practices has accumulated over a lengthy period—and   will not be reversed in short order.</p>
<p>9. Reliability is truly an integrated discipline among engineering, production,   purchasing, and maintenance (in addition to information technology, human resources,   and finance) but is seldom practiced this way. Reliability is unfortunately   often synonymous with maintenance only.</p>
<p>8. Reliability does not come equipped with a widely accepted set of simple   metrics and structure that are broadly understood throughout the organization.</p>
<p>7. Reliability structure and jargon have not been standardized and are often   confusing to the layman, most notably managers and senior executives whose   support is critical to success.</p>
<p>6. Many managers and supervisors are unable to recognize good (or bad) reliability   practices when they see them.</p>
<p>5. Even when they can distinguish good from bad practices, many supervisors   and managers have too high a tolerance of poor performers and poor reliability   practices.</p>
<p>4. Most organizations have a distorted view of reality and are not nearly   as good as they think they are.</p>
<p>3. Reliability initiatives are seldom justified in business terms and, thus,   fare poorly against competing initiatives.</p>
<p>2. We often have the wrong focus for reliability improvement (doing things   right instead of doing the right things). We would improve reliability results   significantly if we spent more time removing the need for maintenance vs simply   rendering maintenance work more efficient.</p>
<p>1. Our understanding and skill at engaging organizational change is woefully   lacking.</p>
<p>This last reason provides the greatest opportunity. Most of us developed   our careers believing that if we made our arguments clearly and logically and   we had the best interest of the organization at heart, our ideas would be accepted   willingly. This is simply a myth.</p>
<p>Resistance to good ideas, including the introduction of sound reliability   practices, can take many forms— from requests for endless detail to outright   silence, and from sophisticated intellectual arguments to misleading compliance,   etc. The underlying causes for resistance are lengthy and center on two main   areas: Loss of control and feelings of vulnerability. We have to understand   these dynamics to facilitate change.</p>
<p>Of course, dealing with feelings and emotions and trying to understand the   nature of resistance to change are not generally the currency of reliability   professionals and they are not addressed too well in the content of most reliability   programs. Yet, these are skills that can be learned.</p>
<p>It is clear that the leadership role in addressing the reasons for our reliability   paradox must come from the reliability professionals, for no one else is up   to the job. No other group has the broad understanding of all of the issues.</p>
<p>The task of educating, collaborating, simplifying the metrics, identifying   the need in business terms, etc., is the responsibility of reliability professionals.   If we do not do this, we will always be on the periphery of the real game while   others take center stage and the business falls well short of achievable results.</p>
Reliability is core to manufacturing-based businesses, and reliability professionals   must take the lead in having this widely recognized. No one else can or will. <strong>MT</strong><br />]]></description>

<span class="dropcap">R</span>ockwell Automation Fair, celebrating the 100th anniversary of Rockwell’s   Allen-Bradley brand, drew more than 14,000 people (customers, speakers, exhibitors,   and Rockwell personnel) to Milwaukee in mid-November.</p>
<p>Displays of advanced technology covering embedded sensors and adaptive control   (including a lubrication sensor for monitoring the health of critical fluids),   diagnostics and prognostics (including adaptive control for motors, pumps,   and fans), open system architecture for condition-based maintenance (leveraging   IEEE and MIMOSA standards), agent-based recon-figurable systems, integrated   information systems, and wireless communication were quite impressive.</p>
<p>No less impressive were pavilions featuring more traditional products and   services, including information and communication technology that can enable   reliability personnel or anyone in the plant with appropriate access to a browser   on the network to query, monitor, measure, trend, and analyze a host of data   inputs: speed, cycles, time, pressure, temperature, vibration, current, force,   process recipes, production rate, analytical reports, inventory, order status,   and more.</p>
<p>As was explained at the Fair, the right system programmed with the right   alarms can tell you when and where to do maintenance. Sounds like a neat trick.   And it is.</p>
<p>These systems provide answers to a number of advanced maintenance challenges.   I’m fascinated by their potential in maintenance and reliability. But   am I, in my enthusiasm, becoming like Anakin Skywalker of Star Wars, in danger   of being seduced by the dark side of the Force and turned into a Darth Vader?   Almost, but not quite.</p>
<p>As intriguing as these systems are, they are only part of the equation. How   do you determine the alarm level? How do you reduce the number of alarms? How   will you respond to the work orders that system kicks out? How do you reconcile   maintenance and production requirements?</p>
<p>Now you are back on the hard-core maintenance engineering side. The control   system can be a powerful tool, but it must be made to serve the maintenance   side of the Force.</p>
<p>Control and automation engineers can be your allies and help you get the   information you need to do the right maintenance if you can get them to understand   the full scope of maintenance engineering.</p>
<p>We must induce them to come over from the dark side. But, which side is the   dark side? It is always the other side. What we really need is the power of   logic and smart business management to enlighten both sides and build a team   to serve the enterprise. <strong>MT</strong></p>

			<title>Monday, 01 December 2003 10:52  -  Making a Solid Business Case for a Maintenance Plan</title>
			<link>http://www.mt-online.com//index.php?option=com_content&amp;view=article&amp;id=1078:making-a-solid-business-case-for-a-maintenance-plan&amp;catid=209:december2003&amp;directory=90</link>
			<description><![CDATA[<h4><strong>Success factors for a business-based approach</strong></h4>
<p><span class="dropcap">W</span>hile most maintenance professionals understand the untapped value hidden   in plant assets, making the case to corporate leadership for maximizing these   assets is an ongoing battle. Perhaps the biggest problem with maintenance is   its historically negative image that prevents it from getting the respect it   deserves. As a result, maintenance is often excluded from the corporate business   planning process.</p>
<p>Nevertheless, maintenance remains one of the few business areas where even   a modest improvement can provide significant increases to company profits.   Therefore, it might be assumed that gaining management support for maintenance   initiatives would be easy. Instead, when maintenance presents its case, it   is often met with indifference and detachment.</p>
<p>How does an organization move from an emergency-mode, fail-and-fix environment   to a culture of predict and prevent? Management has to be convinced that maintenance   is a critical business center that deserves prominent strategic consideration.   A well-conceived plan is necessary to do this.</p>
<p><strong>Developing a strategic plan</strong><br /> No company would attempt to operate without a viable business plan—the   same applies to a maintenance department. As a strategic roadmap, the maintenance   plan should accurately assess the current situation, outline what will be achieved,   and explain how results will be shown. The plan should include documentation   that supports the business case and demonstrates clear, measurable benefits.   It should effectively articulate what will be accomplished and how the activities   will relate to the underlying business goals. Finally, the plan should be logical,   results-oriented, and have a strong sense of urgency.</p>
<p>Managing assets strategically requires that every organizational function   work toward the same goals. Achieving organizational alignment requires building   a case that motivates every level of the organization to become involved. This   means constantly communicating and demonstrating the benefits of the strategy.</p>
<p>Equally important is the goal itself: the simpler, more focused, and more   inspirational the goal, the greater the chance it will be achieved. Once a   shared vision is established, this cohesiveness should lead to positive financial   results, continuous improvement, and breakthroughs in creating value.</p>
<p>Which direction should the plan take? More specifically, what kind and how   much maintenance should be done? The tactical direction of the plan should   be based on critical departmental data, which often resides in isolated information   banks. Understanding what data is available and where it resides provides a   good grasp of whether current systems are delivering the needed capabilities.</p>
<p>One of the basic principles of effective maintenance planning is determining   the right tools for the job based upon the goals and tasks to be achieved.   A computerized maintenance management system (CMMS), for example, offers an   effective platform for sharing data across departments, streamlining reporting   and event tracking, and helping maintenance focus on the right objectives.</p>
<p><strong>Assessing needs</strong> <br /> Before proposing any investments, first conduct a broad-based assessment of     the maintenance and engineering processes, as well as any activities that     support manufacturing. The assessment should identify performance issues,     establish baseline metrics, and outline recommended corrective actions, such     as increased machine availability, reliability, and safety, which can be     implemented through maintenance initiatives. This methodology also provides     the metrics needed to present the value of maintenance to management.</p>
<p>The assessment should highlight the most critical assets and identify any   factors that inhibit equipment or operator performance. When evaluating equipment   criticality, managers also must consider both the probability of failure and   the consequences associated with it. This allows managers to align resources   to provide more attention to high-risk assets and fewer resources to low-risk   assets.</p>
<p>Considerations are given to the environmental conditions and maintenance   history of equipment to produce a mean time between failure (MTBF) report that   predicts how long each component should last, given its performance history   and current working conditions. An asset evaluation provides recommendations   for inventory levels to ensure that all critical parts are available when needed   and excess items are minimized. Companies then can make informed decisions   based on calculated maintenance needs and determine opportunities for improvement   in spare parts inventory.</p>
<p>Benchmarking is another tool managers may use to assess maintenance levels   compared to organizations of similar size and function. Keep in mind that benchmarking   provides baseline comparisons with companies whose practices may or may not   be more effective than yours. Moreover, with benchmarking, the practices under   comparison are largely tactical and seldom reveal any measurable progress or   change in a company’s financial performance.</p>
<p><strong>Integrating the maintenance function</strong> <br /> The ability to integrate maintenance with the rest of the enterprise is a key     ingredient of a proactive strategy and is critical for long-term success.     Only recently has the technology been available to reliably provide the integration     necessary to leverage information across the enterprise. Open communication     networks and advanced software platforms allow companies to improve flow     of information throughout the plant in a cost effective manner, making the     connection from CMMS to production, scheduling, and procurement.</p>
<p>For example, planning long-term shutdowns for capital repairs requires an   understanding of long-term sales and operations planning. Likewise, the plant   supply chain needs to consider and integrate the maintenance function in order   to be responsive and proactive. This requires rethinking how maintenance functions   are executed in an organization as well as providing support through integrated   systems that unite the data requirements across plant-wide systems and processes.</p>
<p><strong>Case study: Continental Tire</strong> <br /> Continental Tire is a good example. As the fourth-largest tire manufacturer     in the world, Continental Tire North America makes nearly 10 million tires     annually. At the company’s Mount Vernon, IL plant, a steady flow of     materials and strong inventory management are required to ensure maximum     production efficiency.</p>
<p>Realizing the importance of streamlining its inventory and parts repair management   process, the company implemented a comprehensive asset management program to   improve equipment reliability and reduce escalating repair costs. Integrated   inventory tracking helps consolidate repairs and track overall repair rates   to identify areas where efficiencies can be built into the process. For instance,   if a pattern of repairs occurs on a particular machine over a period of time,   storeroom managers work with maintenance engineers to find the root cause of   equipment failure.</p>
<p>“ We’ve learned to take an active role and develop creative solutions   to address key issues,” said Ed Stoller, plant manager and head of engineering   at the facility. “For instance, after evaluating a large volume of repairs   and finding a correlation between repairs and increased inventory of spare   parts, we knew we needed to reduce machine failures. We identified one of our   repair vendors as the source and began to test part repairs before sending   them to the plant floor. The solution enabled us to maximize our warranties   and dramatically cut our maintenance expenses.”</p>
<p><strong>Maximizing external resources</strong> <br /> Maintenance departments often struggle with finding enough internal capacity     to handle all their responsibilities. According to the “2002 Maintenance     and Reliability Survey” conducted by Rockwell Automation and M<span>AINTENANCE</span> <span>TECHNOLOGY</span>,     limited manpower (53 percent) and budgetary constraints (47 percent) are     the two most common barriers that keep companies from implementing more comprehensive     asset management programs.</p>
<p>By leveraging external resources to support noncore functions, companies   can more effectively maximize their production assets and quickly adapt to   changing business conditions. Whether applied across an enterprise or focused   solely on maintenance, a collaborative strategy is preferable to reactive quick   fixes, which are more expensive and less effective over the long term.</p>
<p>In practice, a collaborative maintenance strategy can include on-line condition-based   or real-time process control monitoring; direct access to technical assistance,   organization, or procedural changes; customized employee training; storeroom   management; and onsite support or enterprise asset management integration tools.   However it is implemented, the strategy is designed to isolate performance   inhibitors and identify the main factors vital to productivity performance.</p>
<p><strong>Case study: Air Liquide America</strong> <br /> Air Liquide America, a leading supplier of gasses to a wide variety of industries,     is expanding the scope of its predictive maintenance using condition-based     monitoring to help reduce maintenance costs and improve uptime at its U.S.     gas production facilities. The condition-based monitoring equipment enables     the gas supplier to remotely monitor critical machinery and equipment.</p>
<p>Since the majority of its facilities operate automatically or with a single   technician, the company lacked sufficient resources at each site to effectively   use the information gathered from the equipment. The collected data now goes   to a single location where the company uses outside experts to analyze the   information, identify developing faults in equipment, and correct them before   they impact production or safety. The centralization of the data allows the   company to monitor for machinery trends or recurring equipment failure across   all of its sites.</p>
<p><strong>Measuring the value of maintenance </strong> <br /> Developing a set of methodologies for measuring and communicating the return     on investment is the final step in any well-built maintenance plan and will     further support the case for new initiatives. To ensure success, agree with     management up front on how performance will be measured. For example, while     management and maintenance may both measure equipment availability, inventory     turns, uptime, and meeting production goals, management may focus on production     per unit of maintenance or uptime.</p>
<p>The number of parameters that can be measured in a plant is broad. However,   when it comes to developing a strategic plan, less is more because the more   indicators, the greater the risk that two or more will be contradictory. Then   a significant amount of time and effort is spent trying to reconcile the differences,   which distracts from the main task of improving performance. For maximum effectiveness,   use a small number of easily understood measures that are relevant, timely,   and tie closely with business goals.</p>
<p>Perhaps most importantly, the metrics have to be controllable by those who   are being held accountable for performance. The strongest performance measures   are owned by those who can influence performance and use them effectively to   drive performance improvements.</p>
<p>The quality of effectiveness, such as the cost of downtime as a result of   unreliable equipment, needs to be measured to get a true picture of success.   The performance measures should reflect how the maintenance department is providing   value.</p>
<p>Where to place maintenance efforts can be quickly determined by measuring   the production value of downtime. This enables a more accurate focus on the   planning process by identifying what costs the most. What are the patterns?   Where should efforts be focused?</p>
<p>Return on assets (ROA) is another key indicator used to measure the impact   of maintenance activities. ROA is a calculation of how well a company converts   assets to sales and, therefore, profits. By definition, an asset is anything   that has value. However, large numbers of assets tie up cash, increase the   expense of carrying inventory, and reduce profitability. Improving maintenance   can positively impact all sides of the ROA equation. This, in turn, can drive   a company’s stock price and ultimately determine shareholder value—a   metric that corporate leaders are sure to understand.</p>
<p>In considering a measurement strategy, keep in mind that a key factor in   the success of the plan is its ability to deliver early, tangible results.   It is not advisable to design a plan that requires a major up-front investment,   but offers no evidence of improved performance until full-scale implementation   is in place. It is important to come up with a series of short-term, easy-to-demonstrate   wins. Promoting these wins as they happen can build momentum and support for   the plan.</p>
<p>While a well-crafted maintenance plan will not solve all problems, it does   provide a credible platform and the supporting documentation needed to be a   full partner in the business process. More importantly, it widens accountability   for financial performance from the top floor to the plant floor—a trend   that is certain to pay dividends. <strong>MT</strong></p>

			<description><![CDATA[<p><span class="dropcap">I</span>t would be great if every piece of technology ever bought paid immediate   dividends. And if every tool or instrument purchased lived up to its initial   billing and was implemented full scale to perform the jobs it was purchased   for. The reality is that everyone has made a purchase or implemented a plan   with good intentions but never realized the full benefits. This happens for   a reason: going forward with no strategy.</p>
<p><strong>Integral to maintenance<br /> </strong>Airborne ultrasound inspection is an important part of any company’s   predictive maintenance practice. Savings in energy costs, downtime reduction,   catastrophic failure avoidance, predictive lubrication procedures, improved   product quality, improved building safety and efficiency, and increased employee   awareness are some of the benefits of a good program. Despite the obvious benefits,   too many companies have invested in this technology with poor results. They   had a good idea, but they did not have a good plan.</p>
<p>During a plant visit, it is customary for a vendor to be invited out to the   plant floor after a brief presentation of the technology to show the customer   the equipment in action. It does not take long after the customer handles the   equipment to see how easy it is to find a compressed air leak in a noisy plant   environment. Perhaps a faulty steam trap is identified. One customer found   a serious and dangerous fault in a high voltage switch panel the first time   he picked up the equipment.</p>
<p>These immediate findings are impressive, and often enough justification for   a purchase. But finding a faulty steam trap or a compressed air leak does not   save a company any money or improve the efficiency of the facility. It just   identifies a potential problem. A strategy must be in place to repair the problem   once it is found, or even assess if the problem is worthy of the cost of repair.</p>
<p><strong>Setting up a program</strong> <br /> Assembling a team and identifying the needs of an airborne ultrasound program     is an important first step as it serves two ends. First, it will be immediately     discovered that the primary reason for initializing a program is only a small     portion of the final needs list. And, it is a way to bring pessimists and     doubters onboard. If the strategy does not include a way to convince all     those opposed to the project, the project stands little chance of succeeding.</p>
<p>An airborne ultrasound program can address a number of issues in a facility:<br /> •    The compressed air system is full of leaks and compressors are at full capacity. <br /> •      The insurance company wants to see monthly PM on electrical systems. <br /> •      Overlubrication in rolling element bearings is causing unnecessary outages. <br /> •      The company wants to implement a simple but effective condition monitoring     program. <br /> •      The vacuum on key processes cannot be held. <br /> •      Faulty steam traps are taxing the boiler room. <br /> •      Premature pump failures are attributed to cavitation. <br /> •      Leaks in building envelope raise HVAC costs in summer and spring. <br /> •      The company wants predictive maintenance in the hands of many rather than     a few. <br /> •      Troubleshooting complex hydraulic systems will reduce overhaul time. <br /> •      The company wants to integrate technology to complement its infrared thermography     and vibration analysis programs.</p>
<p>Understanding the full scope of ultrasound applications will triple or quadruple   the size of the needs list. See the accompanying section “<a href="#stepsbox">Steps   To Set Up an Airborne Ultrasound Program.</a>” <a name="stepstext"></a></p>
<p><strong>Make the case</strong> <br /> After the general need for an airborne ultrasound program has been identified     and all the key players are onboard, the next step is to refine the needs     and justify the reasons to proceed. Bring together all the key players and     form a task force or decision team. Carefully examine the needs list point     by point, evaluating the relative merits of each item. Capital will be needed     to make the project work and in most cases that will mean selling the idea     to a higher level of management.</p>
<p>Because the initial list is exhaustive and quite possibly long, it may be   overwhelming to upper management. Decide whether it makes sense to present   the entire list or to key on one or two hot points to sell the project. If   the latter makes more sense, then choose one or two (or three at most) applications   and demonstrate how improvements would be justified with an inspection program   in place.</p>
<p>One of the easiest methods to justify ultrasound inspection is leak detection   in a compressed air system. If 40 percent of compressed air capacity is lost   to leaks (the industry norm if no leak program is in place) and that can be   cut to 10 percent (the industry target with a leak program in place), compressor   energy consumption and wear and tear will decrease by up to 30 percent.</p>
<p>Bearing failures are another means of justification. Can key machines that   will shut down production in the event of failure be identified? A $35 bearing   can stop a production line as quickly as a $35,000 bearing. Whatever the justification   that is presented to management, be sure to make a solid business case and   have everyone onboard.</p>
<p><strong>Set goals</strong> <br /> Establishing goals for the program shows that the project is well organized,     the participants are serious about making it work, and everyone agrees on     the direction and scope of the program. Using the same example of compressed     air leaks, the goal can be as simple as reducing leakage from 40 to 10 percent.     Another objective may be to move one compressor to standby service. How about     reducing or eliminating all bearing failures related to improper lubrication?</p>
<p>Wherever the targets are set, they must be realistically attainable, easily   benchmarked, and not carved in stone. Goals exist to add purpose to a project.   Making the goals too rigid or unattainable can have a negative effect or even   kill the program. It is recommended that plateaus be set for each goal and   reviewed on a regular basis to ensure the program is on course and that the   goals still fit the program. Good and realistic goal setting will aid the next   part of the strategy—measuring the return on investment of the ultrasound   inspection program.</p>
<p><strong>Return on investment</strong> <br /> In the first part of the strategy it was suggested to identify all the reasons     why an ultrasound program should be established and then zero in on one or     two key reasons and use those for the justification. If it was rationalized     that an ultrasound inspection program would save the company money by improving     the steam delivery system, a strategy needs to be in place to back up that     claim. How will success be measured? Brainstorm as a team and come up with     some suggestions. Here are a few examples:</p>
<p><strong>Steam traps</strong> <br /> •    Identified and replaced 25 faulty steam traps <br /> •        Increased quality of steam at process end <br /> •        Reduced energy consumption in the boiler room by 15 percent</p>
<p><strong>Air leaks</strong> <br /> •    Found and tagged 75 compressed air leaks in first month <br /> •        Repaired 90 percent of leaks during planned outage. <br /> •        Took electrical readings at the compressor and noticed amp reduction of       28 percent for a savings of $35,500.</p>
<p><strong>Purchase equipment, establish training</strong> <br /> Before selecting ultrasound equipment, arrange an in-house demonstration and     take the instrument to task. Be sure to have a clear understanding of equipment     capabilities, and attempt to get out onto the plant floor and try the equipment     in real-life situations. The section “<a href="#selectionbox">Equipment     Selection Guidelines</a>” <a name="guidetext"></a>outlines some features     to look for in equipment.</p>
<p>Lack of training is the single biggest killer of airborne ultrasound programs.   Users need to be aware of the vastness of applications for airborne ultrasound. “You   mean you can scan electrical switchgear with that thing?” or “We   bought it to find compressed air leaks and had no idea we could use it for   that” are comments heard frequently.</p>
<p>It is proven that certified airborne ultrasound graduates go back to their   respective companies more confident and more resolved to get results from their   program. Knowledge is gold and without it your program is dead.</p>
<p>Certification training should not be restricted to the operators. Both end   users and managers should become certified to at least Level 1. It has been   noted that an ultrasound program would be better served if the managers received   some instruction and understanding about the technology.</p>
<p><strong>Choose a leader</strong> <br /> Leadership qualities often emerge from unlikely candidates. Everyone possesses     the characteristics to become a leader, but is not always thrust into a position     that allows leadership qualities to come through. Based on experience, companies     that have implemented successful and effective airborne ultrasound programs     did not have to look for a leader. After the team was assembled and needs     were identified, a leader emerged by default.</p>
<p>This person played the largest role in identifying the right equipment to   purchase, and excelled during Level 1 training. After the program was implemented,   results were benchmarked and successes were rewarded. When there were doubts,   the leader provided or found an honest and useful answer.</p>
<p>People can lead when called upon as long as they conduct themselves honestly,   have confidence in themselves, can execute with passionate conviction, and,   while able to work in a team environment, ultimately are willing to be fully   accountable for failures within the program. There will be no shortage of people   willing to take credit for the successes.</p>
<p><strong>Reward success</strong> <br /> As important as it is to benchmark results to validate the program, it is equally     important to validate the efforts of the people making it all work. Rewarding     successes can have a motivational effect that will propel the project forward     and ensure its survival during lean times.</p>
<p>One agenda for the regular maintenance meeting should be to establish a reward   structure that is fair and fun. It does not have to cost a lot of money—or   any money at all. It could be as simple as a posted notice on the lunchroom   bulletin board or a mention in the monthly company newsletter.</p>
<p><strong>Review to maintain commitment</strong> <br /> As part of the regular maintenance meeting, time should be set aside to review     the progress of the project. This process should not be difficult. Pull out     the written strategy and goal sheet and one by one address each point to     ensure everyone is on target.</p>
<p>Are goals being reached or do they need to be revised? Are the goals set   too low? If so, revise them with more challenge, and therefore more positive   impact for the project. Acknowledge participants who have given more effort   than required and open the floor to allow a free flow of knowledge exchange.   Use this forum as an opportunity to share new ideas and new uses for the tool.</p>
<p>Document the findings and contact the equipment supplier to write a case   study. Getting published in a nationally distributed trade journal can be a   satisfying and motivational experience. Publish the review on the company intranet.   Frequent review of results will ensure that everyone involved is 100 percent   mentally invested in the success of the program.</p>
<p>Airborne and structure-borne ultrasonic inspection provides industry with   an efficient solution for all kinds of preventive and predictive maintenance   functions. It is considered by some to be the most important reliability tool   based on its versatility, low cost, and ease of use. It is a tool that can   be used right out of the box with immediate success and payback. A program   strategy based on the steps outlined in this article will ensure the success   of ultrasonic inspection in virtually any industry. <strong>MT</strong></p>

<p><a name="selectionbox"></a><strong>EQUIPMENT SELECTION GUIDELINES<br /> </strong>• Quality: A first class program needs first class equipment.<br /> •   Accuracy: The strategy is dependent upon benchmarking so whatever data is collected   needs to be accurate.<br /> •   Repeatability: Monitoring the condition of rotating equipment involves trending   and comparing data that is repeatable.<br /> •   Digital: Choose equipment that uses current technology. If the equipment is   not true digital it cannot be used for accurate data trending.<br /> •   True RMS: How the signal is measured is as important as how it is stored. Equipment   with true RMS capability provides a signal that is linear and stable for accuracy   and repeatability.<br /> •   Easy to use: Controls should be logical and accessible.<br /> •   Upgradeable software: Can the system be enhanced with future upgrades?<br /> •   Route capable data collection: This is necessary for benchmarking.<br /> •   Multi-functional: Some manufacturers offer sensors with added functionality   such as temperature guns, tachometers, noise sensors, and flow meters. <br /> •   Warranty: Extended warranties are often available.<br /> •    Training: Look for equipment that offers certification training. A 2½ day   ASNT approved course is normally sufficient to get users and managers up to   speed.</p>
