Hydrocarbon Processing 3rd International Conference on Improving Reliability in Petroleum Refineries and Chemical Plants |
| "Courage is the price that life exacts for granting peace. The soul that knows it not, knows no release from little things; Knows not the livid loneliness of fear, Nor mountain heights where bitter joy can hear the sound of wings." |
|
Amelia Earhart
|
| The reliability culture can be described by three words, focus, proaction and priority. These are essential components of reliability. The questions are "to focus on what?" and "proact to what?" Priority gives focus and proaction its direction and support. All three components are of extreme importance if reliability operations are to produce truly outstanding results. |
| Can we intellectually agree that facilities that focus on the most important issues and that proact to prevent surprises and deviations from effective operation will be most likely to turn in superior results? The writer would like to look at all three of these reliability components from a human aspect because when they do not exist and poor performance results, the fix is clearly a human issue. |
| Priority |
| Priority exists when senior management clearly delineates an institution's direction and assigns responsibilities. There is one more factor management must also put in place, that is, the support mechanisms to facilitate the work of line managers. In this way they dramatically demonstrate to the population involved that they sanction the direction line managers are pursuing. In other words, to use a cliché? of today, they will be "walking their talk". |
| To effectively perform their part in a needed cultural shift, senior management must aid the focus effort by establishing a rallying vision. The wording of the vision becomes extremely important if it is to influence needed behavior changes. It is one thing to say we want to achieve a 10% increase in market share in five years but it is more of a rallying vision to say we will either be number one or number two in the market place for our products in five years or we will not be in that business. This was, of course, done by Jack Welch of General Electric. |
| To establish priority, senior management must participate in open debate on the paradigm shifts that will be needed to achieve quantum results. The outcome will be agreement on what thinking must be changed. Knowing this, senior management can provide the necessary support. Senior management should expect some organizational people to yell foul when a change in their behavior is expected. Indeed, if there is no human system noise assume that changes are not taking place. |
| To sum up, when a cultural shift is necessary to achieve superior performance, senior management must be part of the process. They need to examine what thinking and behaviors need to change, including their own, to get the process started. They certainly need to set out the vision, goals and values that they want the organization to achieve and they have to make the appropriate policy changes. Beyond this they need to provide visible support, track the change agents and clear obstacles. |
| Focus |
| Focus is the directing of human energy and capability to the significant few issues and opportunities that result in quantum benefits. Now, this appears to be so logical we have to ask ourselves why isn't it generally done? |
| Most manufacturing facilities have, within their fence line, the capability to solve most of their problems yet they continue to be hampered by recurring failure events. In fact, what do most field people do daily but attend to chronic problems. |
| Two mindsets prevail that are instrumental in limiting our ability to focus: |
|
| Can you argue that these are not representative of the thinking of organizational people probably at all levels? What this represents is a dilemma for most people. Either I work on the trivial many or I challenge my job assignments. The first decision promotes mediocrity, the second may be perceived as insubordination. In fact, challenges to job assignments can polarize relationships between bosses and subordinates. |
| The answer is to challenge but to do it in a way that is not perceived as being insubordinate. One can do this by using a variety of prioritization techniques. This reduces the challenge to a technique on a piece of paper, permitting the supervisor to see the logic of the challenge. Indeed the supervisor can modify the priority by interjecting his or her own logic. He or she may even use the document to present the field view to their own boss, if necessary. |
| Some of the techniques for establishing reliability focus are: |
| Managerial Introspection |
| This is a way of focusing that requires the management team to examine the health of the organization by first establishing a rallying vision of the future along with the values that they want the organization to represent. This is followed by a day long introspection of the health of the organization for which they are responsible. Finally, a focused plan is developed for moving the organization forward. If the organization is found to be unhealthy, as is observed in many plant organizations, then the result of this session is a twofold plan, one to restore health and one to move forward. |
| Modified Failure Modes and Effects Analysis |
| Instead of concentrating personnel solely on the failures that are perceived as being of interest to senior management, or the most dramatic failure of the day, we need to concentrate our trained resources on those failures that are most important to achieving and exceeding our financial targets. To do this, a very effective technique, developed in the aerospace industry, has been simplified and made user friendly making it applicable to the continuous process industry. The result is a method that captures vital information held by people in the field that is usually not found in our data systems. |
| Consequently, a modified version of Failure Modes and Effects Analysis uses field resources to develop the information that identifies which failures represent 80% of facility losses. The technique, although somewhat subjective, is powerful and very capable of identifying the significant few failures that should be subjected to Root Cause Failure Analysis. |
| Decisions by Pairs |
| As employees of companies, it is our tradition that orders for performing work comes from our bosses. It is also our tradition that objections to such orders are not usually tolerated. Since traditions are our paradigms, they have the effect of promoting mediocrity. They also represent a dilemma for employees....do I challenge job assignments or do I continue to work on the trivial many? Decision by pairs is one technique that provides a vehicle to challenge work assignments in a non-personal way. It allows a list of jobs that need attention to be prioritized by comparing each job with each of the other jobs to be done and then sorting the list according to how many times a particular job is selected. |
| Priority Matrix |
| Priority Matrix is a technique that is two dimensional. This means that instead of comparing the importance of one job with the importance of other jobs, we can sort on the basis of the impact of a job as well as the ease of achieving the job. |
| When we allow subordinates to question priorities we are, in effect, allowing limits to be challenged and opening up our plants to some very real progress. |
| Proaction |
| I define proaction as any improvement, foresight and/or execution activities that will prevent equipment, process or human failure or lessen the consequence of failure. |
| I want to discuss, in human terms, mechanical, process and human proaction. |
| Mechanical Proaction |
| To achieve mechanical proaction we must predict how our machines are failing or are likely to fail. When we discussed Focus we talked about a technique called Failure Modes and Effects Analysis, a tool to help us identify failure modes. Having knowledge of failure modes, we can take steps to avoid these occurrences and develop early warning signals of their impending happenings. What is generally missing are standards of acceptable performance and how to achieve them. Take for example rotating equipment such as pumps, pacesetters are using standards that are getting them six years average life on their pumps instead of the two years that is generally found acceptable. To understand how to achieve this higher standard let us examine three vital up front activities that we perform to put rotating equipment in service: namely, balance, assembly and alignment. |
|
|
|
|
|
|
|
|
| What about cost? |
| Consider an average plant that has 1200 pumps and average repair cost of $5,000/pump. This assumes all costs involved including the procurement & storage costs of parts, cost of supervision & technical support, cost of tools and rigging equipment, cost of overhead burden and finally the cost of person power and their overtime. (We have been advised that this cost may very well be $7,500 to $10,000 per pump). |
| This is a clear savings of $2,000,000/yr.. It can be more if the people freed up can be assigned proactive work with other equipment including the fixed equipment. |
| Process Proaction |
| We know who the performers are in our operating units. What we generally do not know is what factors separate them from the average field operating person. When we think of these performers or groups of performers, we generally recognize their fine behavior traits. This is, of course, normal but what we need to do is define these exemplars not in terms of their behavior but rather in terms of their demonstrated performance. |
| Once the performance parameters are defined, usually in terms of quantity, quality or cost, we need to define the gap between the exemplars and the average producers. It is likely that more than one measure of performance will be needed. It is also likely that, upon reflection, we will find that the parameters that we are seeking are not currently being measured. If this is the case, it will be necessary to set up the means to measure the performance gap. |
| Once metrics are put in place, they will define the performance gaps so that the opportunities to improve average performance can be realized. Analysis of the gap may reveal that the average operator lacks confidence in their ability to handle some off standard conditions or perhaps some shifts have better teamwork than others. Whatever the case, it is incumbent on management to develop a strategy to close the gap. |
| The tendency is to center our attention on attitudes, yet, throw up our hands when we find how difficult it is to directly influence attitudes. The writer is suggesting that we center our attention on performance to identify exemplars and define the opportunity gap. We then center on analyzing the reasons for the gap and developing strategies to close the breach. These strategies include training, tools, job aids, recognition programs, field reinforcement of learned methods, as well as management system changes. Management system changes may include: speeding up decision making, installing feedback mechanisms, and/or field audits, to name a few. |
| Human Proaction |
| Human proaction starts with inculcating productive paradigms. To do this we need to know something about paradigms. Joel Barker's film on "Discovering The Future" does an excellent job of introducing people to paradigms and their effects. If you have seen the film then you will see that the writer's treatment of paradigms complements what Barker presents. |
| The first thing to consider is the distinction between a mindset and a paradigm. A mindset is a deep seated conviction, value or way of doing something that we, as individuals, possess. When the same mindset is shared by a significant number of people in a population, like a department or plant, it becomes a paradigm. So a paradigm is always a mindset but a mindset may not be a paradigm. |
| Consider that we are the most technically advanced society on the face of the earth and yet many of us struggle to gain economic advantage over our competitors in other nations. How can this be? The writer has found numerous examples of manufacturing plants being held in bondage by their own thinking, their paradigms. For example, plants that are so used to playing the incremental stretch game that they do not stop to analyze the gap between unrestrained production at their highest demonstrated rate for quality products versus their present situation. This relatively simple task often reveals enormous opportunities. |
| Some people have expressed to the writer that they tire at the use of the word ... Paradigm. This is truly unfortunate because it conceptually captures the power that our thinking has over our behavior. If we believe in a cause or a direction strongly enough we can do extraordinary things, like landing on the moon. If we believe in false limitations, like not being able, as human beings, of running a mile in less than four minutes, we will find ourselves dead in the water, incapable of any meaningful progress. |
| The writer has numerous examples of paradigms that have restrained progress: |
|
|
|
|
|
|
| It is unfortunate that census reductions take place before non-value added work is reduced, yet, it may be the only way that senior management can realize the financial results needed. Obviously, the answer is to define work that is non-value added and develop means to reduce and/or eliminate it. This will open time slots that can be used to relieve the workload, reduce frustrations, restore home lives, and create the potential for moving people into more proactive activities. |
| The writer often hears the admonition that operators or mechanics or both are not pulling their load. This is certainly disheartening. Experience tells us that in many of the cases it stems from not holding people responsible for their work. |
| Manufacturing plants need to establish criteria of performance, not of behavior, and devise strategies to obtain the criteria. The criteria have to be dynamic because management will reasonably continue to ask for the next plateau of excellence. The way people perform, to each level of criteria, will be a measure of their competence. |
| "Reliability is the job of a central core group, not the job of everyone" is a common refrain. If people do not know how they can participate in an activity, it is reasonable for them to assume that it is some other person's job. This is both an educational and a management system matter. |
| "Management really wants people that can react and get the facility back on the line". Reaction is too often rewarded, creating a sense of fulfillment for this type of activity. This, of course, perpetuates mediocrity because it discourages proaction and continuous improvement. All that is needed is to change what people get rewarded for. |
| Finally, the writer often senses deep seated feelings from field people that they are required to use old equipment or push existing equipment beyond its ability to provide consistent flows and quality products. This is certainly a breeding ground for assumptions but it could also be an early warning system if the reasons for the feelings are listened to and evaluated. Feedback to the claimant can help dispel the false assumptions. |
| Paradigms are often formulated by assumptions that people make about their world. When management makes pronouncements, institutes new policies, or merely praises or criticizes work that has been done, there will be assumptions made. These assumptions might include how people will be affected and how they will survive and prosper. The assumptions made as a response to management's message can very well become deep seated values or paradigms. |
| So how do we handle this problem of paradigms? The mind is, of course, dynamic, not static. As a result, our mindsets are being continually honed by new information. Regrettably, most of the time we will distort the information to preserve our mindsets if they truly represent our deep seated values. To move people out of their restraining mindsets we must, at times, be prepared, be bold and a little bit outrageous. |
| One strategy is to change people's jobs. The writer had one client whose organization was not making headway because incumbent managers were shackled in their thinking by the turf that they felt they had to protect. One bright morning the General Manager, my client, came to work and announced that all nine of his managers suddenly had new jobs. Each of them now had the responsibility of one of their colleagues. What the General Manager did was unshackle them from their past. He gave them a new beginning but he lost none of their experience. And it worked. |
| We can move people to new environments or we can introduce radically new technologies. Each of these strategies will force the establishment of new thinking. However, often we do not have the liberty to use these strategies. The writer has experienced two additional strategies that work. One is to provide the training and tools to perform the old job to new and more exacting standards of performance. The other strategy requires management systems that provide speedy responses to worker's creativity, thus giving them a sense of fulfillment. |
| The writer has also seen in-house advertising succeed providing that it is straightforward and honest. The model to use here is the evolution of our approach to safety. In-house advertising usually takes more time because here the thrust is changing attitudes, a time consuming activity. It can be speeded up if it is combined with the aforementioned strategies. |
| This discussion would not be complete if we neglected to discuss training and alienation, wrapping it together with human error and its consequences. Starting with training, it is imperative for both operating and safety reasons that people know their jobs. They really cannot respond to operating deviations or precision repairs if they simply do not know what to do. Sure they can fake it and get by most of the time because the work environment is quite forgiving and, frankly, so are we. When we allow shoddy workmanship to stand we are contributing to the mediocrity that it engenders. |
| A familiar refrain of the writer is the advice that because people, for the most part, cannot reveal their deficiencies of knowledge or skill it is incumbent on management to ferret out the educational gaps. The writer suggests that needs assessments be implemented to provide needed information on knowledge and skill gaps. |
| The Next Step Is Training |
| Once the gaps are determined the next step is training. To train effectively, we must first isolate the specific performance we want to improve, translating it into training criteria. |
| The training must accomplish two things: it must fulfill a perceived need and it must link to existing knowledge held by the student. For students to absorb information and transform it into personal knowledge, the training information needs to be presented in more than one form to make the necessary linkages. |
| Additionally skills training must present opportunities for repetitive use of the skills learned. It is necessary to practice the skill in the classroom but it is also very necessary for the supervisors to allow and encourage the skills to be used on the job. This means that the supervisors are a necessary part of the training cycle. |
| Once the students are back on the job for a time, their performance must be matched against the original criteria to assure the training was effective. To this end the writer recommends that critical skills such as vibration analysis, machine alignment and balancing be assessed by experts to assure that any gaps found can be closed by reinforcement from the experts. |
| We also have to concern ourselves with alienation because if we are estranged from our bosses, subordinates or colleagues, this excess emotional baggage has the effect of reducing our ability to be sensitive to our surroundings. We need to be sensitive to our work environment to operate effectively and to prevent sporadic failures. The writer recognizes that alienation will never be totally eliminated but we can significantly reduce it, if we are aware of it. |
| The writer earnestly believes that attention to these key issues: knowing job content and reducing alienation, will significantly influence performance, safety and environmental integrity. This is true because the environment we work in is very forgiving. If we raise our sensitivity to our surroundings a notch or two we will materially affect performance. |
| The job environment is said to be very forgiving because even though we, as human beings, are error prone we generally survive our own mistakes. We see this graphically in the Error Change Phenomenon. It is reported that it takes 10 to 14 errors and their associated changes before a random event occurs, such as an unpredicted failure, fire or explosion. Because of this, we realize that we need to recognize errors, our own and others, and break the chains leading to disaster. Remember, when we remove a tripping hazard, we are breaking an error chain. When we are too close to another car and maneuver to increase the distance between the vehicles, we are breaking an error chain. |
| Breaking chains by becoming more sensitive to our surroundings is vital in modern day plants because of the danger of massive injuries and product flow disruptions. The danger is usually very high primarily because of the ever increasing horsepowers and speeds of modern machinery. In addition, the danger escalates with production materials that can cause fire, explosions and chemical or radiation poisoning. |
| In summary, insuring that field personnel know their jobs and how to perform them will increase their sensitivity to the their job environment. Likewise, the reduction of alienation will reduce emotional baggage and increase their sensitivity to their surroundings. Since our world pardons many of our mistakes, in that it takes a multiple of errors to cause a triggered event, this will materially improve operational performance and reduce the chance of accidents and environmental excursions. |
| Now that what needs to happen has been laid out, we need to understand how we can modify operations to achieve quantum benefits. It has been the writer's experience that such transformations can occur within one to two years and at the outside five years. Remember that many folks promoting such transformations approach the subject by trying first to change attitudes with the belief that improved performance will follow. This can work, but it generally takes between five to ten years to accomplish quantum benefits, and sometimes even longer. |
| It is the writer's position that change can take place faster by forcing modifications in behavior as long as they do not violate the values of those individuals involved in the change. Thinking will begin to shift if the forced behavior is accompanied by education, participation and experiencing the fruits of new value systems. It becomes apparent that timing is important, the motivation of the people involved is important and the sensitivity and skill of the champion advising and directing this change is important. |
| A word about the consultant that will most likely advise management and provide training and special expertise. It is vital to have someone that has had direct field experience in transformations. Without it the consultant cannot empathize with the parties involved and understand the particular dynamics occurring in the facility. |
| The consultant or advisor should not develop a plan for the change. The plan must be developed by the people responsible for operational performance. They will, hopefully, choose to involve various others in the facility. When the plan is final it must be the facility's plan. The advisor should be called upon to review the plan in the draft stage, but he or she cannot be a decision maker respecting the plan. Recognize that it is easy for consultant's plans to fail. It is much harder for management's plans to fail. |
| To accomplish a transformation that will assure a company's or a plant's ability to compete in the next century, the following changes in thinking need to occur: |
| Presentsight - Foresight |
| It will be impossible to compete if companies continue to suffer surprises, whether they be operational upsets, equipment failure or major financial deviations. |
| Recognize Reaction - Recognize Proaction |
| We cannot continue to ignore the mountains of psychological evidence that says we respond to recognitions and rewards. As human beings we tend to replicate behavior for which we are recognized and rewarded. It is no wonder that reaction is in big demand since in our society we tend to recognize reaction, not proaction. |
| Criticize Constructive Insubordination - Recognize a Challenge to Existing Limits |
| We certainly do not need people who are disruptive but we do need critics as well as people who are creative and inventive. The critics may appear to be disruptive but, if they are challenging existing limits we need their help to boldly move forward. |
| Supervisor Accountability - Doer Accountability |
| We need to recognize the role of the current day supervisor. It is to guide, to train the people for which he or she has responsibility and to facilitate their needs to accomplish their work. In this way they become leaders. We also need to recognize that the people doing work should be responsible for their work but are most often not held accountable. Accordingly, we need to create new work environments that hold supervisors responsible for facilitation, training and guiding. Operators and mechanics must be held responsible for their tasks and performance, whether individually or in teams. |
| Restricted Information - Open Flow of Information |
| There is surely a greater flow of data today but not information. Data must be reduced to wisdom. It must be presented in a way that helps people convert it to personal knowledge. The science to help us do this is called instructional technology and we have to learn to use it effectively. |
| Do Everything That Comes Up - Do What Is Most Important |
| Certainly one of the most powerful impediments to progress is our inability to concentrate talented work forces on the issues in a plant that are MOST important. It is generally conceded that almost everything employees are asked to do in a plant is important. The writer observes that in facilities that have a lot of system noise, confusion and inefficiencies, there is no discernment of what is most important. Plant supervisors and managers certainly need to accept challenges to assignments not viewed as important as the current work and devise means to target resources to what is truly most important |
| Field Procedures That Protect Legally - Field Procedures That Work |
| Many, if not most, field procedures are written without knowledge of how the human sensory system and the brain absorb information and use it. Some procedures are written to satisfy legal requirements. Yet, what needs to occur is to develop user friendly procedural products that make great use of graphics, color, instructional technology and human factors engineering techniques. Our goal must be easy understanding of not only how to do something but also why it needs to be done. |
| Spot Learning - Continuous Learning |
| We tend to take for granted what people know. We must realize that it is difficult for people to say they don't know something when they are already being paid to perform specific tasks. In many cases they muddle through but they can not provide the precision needed to allow their plants to become pacesetters. The answer is to learn the science of instructional technology and apply it so that people truly know every facet of their jobs. Additionally, we have to strive for work environments where employees feel free to tell us what they don't know or understand. |
| Big Ticket Improvements - Continuous Improvement |
| In the United States we have, in the past, concentrated our efforts on effecting big improvements in our equipment and processes. This has often been done at the expense of smaller but needed improvements. Some of our Japanese competitors have been extraordinarily successful in making small improvements work for them. The USA can also make small improvements work for them but they must reduce the bureaucracies that are often set up to handle improvements. This would mean that the burden for following through on small improvements would fall on the 1st line supervisors. Bearing this burden would only be possible if the role of the supervisor is changed as has been stated above. Supervisors need to be relieved of the responsibility for the work of their employees but become responsible for facilitating that work. This is in no way suggesting that plants should relax their responsibility to manage change. |
| Supervisors as Pushers - Supervisors as Coaches |
| In the forties we called 1st line supervisors "pushers" because their job was to push the workers, thereby assuring a fair day's work for a fair day's pay. At least that was the theory. Over the years, we have tried to shift this paradigm by relabeling pushers as foremen, supervisors and even managers, yet we still held them responsible for the work. In the future, 1st line supervisors will become facilitators, trainers and coaches while people who do the field work will be held responsible for their own performance. Many forms of this scenario are beginning to appear but, in many locations, our old mindsets are formidable barriers to progress in this regard. |
| Non-Value Added Work Accepted as Routine - Non-Value Added Work Continually Pruned |
| In plant after plant, we hear the lament that staffs have been cut so much that it is impossible to pursue proactive work. Yet, in these plants one can observe a preponderance of non-value added work being done. Price Waterhouse reports that between 88% to 92% of all the work done in American factories is non-value added. When we make up our minds to do something about this we will begin to open pockets of time for proactive activities. |
| Identifying Potential Failures - Reducing Potential Failures |
| We have come to believe that the more progressive plants have reliability groups that predict potential failures. What we must remember is that true reliability can only be realized when we reduce our dependence on prediction. This is not to say that prediction is not important but more important is the need to prevent the need for prediction. We do this by increasing the preciseness of our work. We no longer accept the standards of the past but adopt new higher standards of workmanship for equipment, parts, assembling equipment and processing products. |
| Focus on Sporadic Failures/Problems - Focus on Chronic Failures/Problems |
| Our practice has been to avoid and study our more catastrophic failures. Certainly on the surface this is hard to argue. However, as we discover that the chronic failures are costing us more over time than the larger sporadic failures, we begin to see that there is a need to shift our focus. What has been fooling us is the frequency factor. Without multiplying by frequency our small failures remain small but when multiplied they become huge. The writer is not advocating abandoning efforts to avoid sporadic failures but he is advocating a shift in focus. |
| Discipline People Who Make Mistakes - Find Management System Causes |
| The theory has been that if we punish people for making mistakes they will not repeat them. Further, as the punishment is subtly made public their colleagues will also avoid the same mistakes. This sounds logical but it has not worked. Failure rates are rising. The explanation lies in the "Error/Change Phenomenon" that we already discussed. When we have a sporadic event like a fire, explosion or merely an equipment failure there is a multiplicity of errors that lead up to the event. When we punish an individual for his or her mistake we drive the information on the other 9 to 13 mistakes underground. Thus, we have not really solved the problem because we did not uncover all its root causes. This needs to change. But to effect the change we have to shift a very old paradigm. |
| Prerequisites for Transformation |
| These represent the changes that are needed. The question remaining is how do we change or transform to achieve quantum benefits and provide a work place that has less stress and offers more fulfillment. We start with the following prerequisites: |
|
|
|
|
|
|
|
|
| Transformational Strategies |
| Now we know the prerequisites, what are the means? The means vary depending upon the organization, its prior conditioning and what needs to be accomplished. Although some consultants would like you to think there is a cookbook and they have it, the writer has not been able to experience "like" situations. Each plant has its own uniqueness. Following are some of the strategies that have worked for the writer. They are not presented as an all inclusive list but can be very effective in the right circumstances: |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
| In summary, the writer has experienced manufacturing locations that have outstanding successes. Because of this experience and the writer's observations of manufacturing, generally, he is enthusiastic about our future. We have always found the will and the courage to rise to the occasion. We are currently on the move and are experimenting with a number of means. We are pointed in the right direction. |
|
The Reliability Approach works. It is the infrastructure that supports
organizational health, quality, safety and environmental integrity. To
achieve the challenge of setting the Reliability Approach in place will
require a number of conditioned paradigms to change. This will take boldness
and courage. We are up to the task. If we can delineate the challenge in
an uplifting vision we can even have fun realizing extraordinary performance
far beyond what we have become conditioned to expect.

| "Most people live, whether physically, intellectually or morally, in a very restricted circle of their potential being. They make use of a very small portion of their possible consciousness, and of their soul's resources in general, much like a man who, out of his whole bodily organism, should get into a habit of using and moving only his little finger. Great emergencies and crises show us how much greater our vital resources are than we had supposed." |
