The Most Common Mistake Made in RCM

In 1978 F. Stanley Nowlan and Howard F. Heap released a United Airline study that contained a new methodology called Reliability Centered Maintenance (RCM). This methodology quickly became the gold standard for risk assessment and risk management.

As the years progressed, two major improvements happened:
1) Improvements in the use of advanced statistics to analyze machinery failure patterns shed new light on the nature of how machinery fails, and
2) Advancements in computer technology produced extremely powerful inspection methods that changed the face of assessing a component’s condition.

Very few practitioners of RCM kept up with either of these changes, and as such, the development of a comprehensive and efficient equipment maintenance plan (EMP) became a resource-consuming process.

The core of RCM Analysis lies in the answer to seven questions.

1. What are the functions and associated desired standards of performance of the asset in its present operating context (functions)?
2. In what ways can it fail to fulfill its functions (functional failures)?
3. What causes each functional failure (failure modes)?
4. What happens when each failure occurs (failure effects)?
5. In what way does each failure matter (failure consequences)?
6. What should be done to predict or prevent each failure (proactive tasks and task intervals)?
7. What should be done if a suitable proactive task cannot be found (default actions)?”

Note question number six - inspection techniques that adequately identify defects during normal operation are preferred over those that require downtime. Less invasive is preferred to more invasive. This is one of the fundamental concepts of any well-defined maintenance strategy. It is a bit ironic that RCM prefers inspections during operations (the use of Condition Monitoring techniques) and it is this category that most faithful RCM facilitators have traditionally overlooked or misunderstood.

Example: It is not uncommon for an RCM facilitation to result in Vibration Analysis or Ultrasonic Analysis as the primary strategy for determining an inadequate lubrication fault on a rolling element bearing. Some of these same RCM analyses have resulted in all lubrication tasks being replaced by “on-condition lubrication”. This is incorrect. While it is true that either of these two technologies can easily detect high frequency noise coming from an inadequately lubricated rolling element bearing, using either of these technologies to alert you to when a bearing needs lubricating is damaging to the bearing, and therefore, an incorrect strategy. The high frequency noise comes from metal to metal contact as a result of an insufficient lube film, therefore when you hear the noise, metal to metal contact is already happening and irreparable damage has already occurred. The point of a lubrication strategy is to prevent this metal-to-metal contact from ever occurring. The correct strategy is to lube the bearings on a time-based interval with a properly designed and formatted procedure by a trained and qualified lubrication technician.

Goal Setting

Goal Setting Powerful Written Goals In 7 Easy Steps!
by Gene Donohue

The car is packed and you're ready to go, your first ever cross-country trip. From the White Mountains of New Hampshire to the rolling hills of San Francisco, you're going to see it all.
You put the car in gear and off you go. First stop, the Baseball Hall of Fame in Cooperstown, New York.
A little while into the trip you need to check the map because you've reached an intersection you're not familiar with. You panic for a moment because you realize you've forgotten your map.
But you say the heck with it because you know where you're going. You take a right, change the radio station and keep on going. Unfortunately, you never reach your destination.
Too many of us treat goal setting the same way. We dream about where we want to go, but we don't have a map to get there.
What is a map? In essence, the written word.
What is the difference between a dream and a goal? Once again, the written word.
Goal setting however is more than simply scribbling down some ideas on a piece of paper. Our goals need to be complete and focused, much like a road map, and that is the purpose behind the rest of this article.
If you follow the 7 goal setting steps I've outlined in this article you will be well on your way to becoming an expert in building the road maps to your goals.

1. Make sure the goal you are working for is something you really want, not just something that sounds good.

I remember when I started taking baseball umpiring more seriously. I began to set my sites on the NCAA Division 1 level. Why? I knew there was no way I could get onto the road to the major leagues, so the next best thing was the highest college level. Pretty cool, right. Wrong.
Sure, when I was talking to people about my umpiring goals it sounded pretty good, and many people were quite impressed. Fortunately I began to see through my own charade.
I have been involved in youth sports for a long time. I've coached, I've been the President of leagues, I've been a treasurer and I'm currently an Assistant State Commissioner for Cal Ripken Baseball. Youth sports is where I belong, it is where my heart belongs, not on some college diamond where the only thing at stake is a high draft spot.
When setting goals it is very important to remember that your goals must be consistent with your values.

2. A goal can not contradict any of your other goals.

For example, you can't buy a $750,000 house if your income goal is only $50,000 per year. This is called non-integrated thinking and will sabotage all of the hard work you put into your goals. Non-integrated thinking can also hamper your everyday thoughts as well. We should continually strive to eliminate contradictory ideas from our thinking.

3. Develop goals in the 6 areas of life:

Family and Home
Financial and Career
Spiritual and Ethical
Physical and Health
Social and Cultural
Mental and Educational
Setting goals in each area of life will ensure a more balanced life as you begin to examine and change the fundamentals of everyday living. Setting goals in each area of life also helps in eliminating the non-integrated thinking we talked about in the 2nd step.

4. Write your goal in the positive instead of the negative.
Work for what you want, not for what you want to leave behind. Part of the reason why we write down and examine our goals is to create a set of instructions for our subconscious mind to carry out. Your subconscious mind is a very efficient tool, it can not determine right from wrong and it does not judge. It's only function is to carry out its instructions. The more positive instructions you give it, the more positive results you will get.
Thinking positively in everyday life will also help in your growth as a human being. Don't limit it to goal setting.
5. Write your goal out in complete detail.

Instead of writing "A new home," write "A 4,000 square foot contemporary with 4 bedrooms and 3 baths and a view of the mountain on 20 acres of land.
Once again we are giving the subconscious mind a detailed set of instructions to work on. The more information you give it, the more clear the final outcome becomes. The more precise the outcome, the more efficient the subconscious mind can become.
Can you close your eyes and visualize the home I described above? Walk around the house. Stand on the porch off the master bedroom and see the fog lifting off the mountain. Look down at the garden full of tomatoes, green beans and cucumbers. And off to the right is the other garden full of a mums, carnations and roses. Can you see it? So can your subconscious mind.
6. By all means, make sure your goal is high enough.
Shoot for the moon, if you miss you'll still be in the stars. Earlier I talked about my umpiring goals and how making it to the top level of college umpiring did not mix with my values. Some of you might be saying that I'm not setting my goals high enough. Not so. I still have very high goals for my umpiring career at the youth level. My ultimate goal is to be chosen to umpire a Babe Ruth World Series and to do so as a crew chief. If I never make it, everything I do to reach that goal will make me a better umpire and a better person. If I make it, but don't go as a crew chief, then I am still among the top youth umpires in the nation. Shoot for the moon!
7. This is the most important, write down your goals.
Writing down your goals creates the roadmap to your success. Although just the act of writing them down can set the process in motion, it is also extremely important to review your goals frequently. Remember, the more focused you are on your goals the more likely you are to accomplish them.
Sometimes we realize we have to revise a goal as circumstances and other goals change, much like I did with my umpiring. If you need to change a goal do not consider it a failure, consider it a victory as you had the insight to realize something was different.

So your goals are written down.
Now what?
First of all, unless someone is critical to helping you achieve your goal(s), do not freely share your goals with others. The negative attitude from friends, family and neighbors can drag you down quickly. It's very important that your self-talk (the thoughts in your head) are positive.
Reviewing your goals daily is a crucial part of your success and must become part of your routine. Each morning when you wake up read your list of goals that are written in the positive. Visualize the completed goal, see the new home, smell the leather seats in your new car, feel the cold hard cash in your hands. Then each night, right before you go to bed, repeat the process. This process will start both your subconscious and conscious mind on working towards the goal. This will also begin to replace any of the negative self-talk you may have and replace it with positive self-talk.
Every time you make a decision during the day, ask yourself this question, "Does it take me closer to, or further from my goal." If the answer is "closer to," then you've made the right decision. If the answer is "further from," well, you know what to do.
If you follow this process everyday you will be on your way to achieving unlimited success in every aspect of your life.

The difference between a goal and a dream is the written word.-Gene Donohue

SMART Goal Setting




I encourage you to pick up a pen and a piece of paper and jot down the goals you want to reach. Look at each goal and evaluate it. Make any changes necessary to ensure it meets the criteria for a SMART goals:

S = Specific

M = Measurable

A = Attainable

R = Realistic

T = Timely


Specific
Goals should be straightforward and emphasize what you want to happen. Specifics help us to focus our efforts and clearly define what we are going to do.
Specific is the What, Why, and How of the SMART model.

WHAT are you going to do? Use action words such as direct, organize, coordinate, lead, develop, plan, build etc.

WHY is this important to do at this time? What do you want to ultimately accomplish?

HOW are you going to do it? (By...)
Ensure the goals you set is very specific, clear and easy. Instead of setting a goal to lose weight or be healthier, set a specific goal to lose 2cm off your waistline or to walk 5 miles at an aerobically challenging pace.

Measurable
If you can't measure it, you can't manage it. In the broadest sense, the whole goal statement is a measure for the project; if the goal is accomplished, the is a success. However, there are usually several short-term or small measurements that can be built into the goal.
Choose a goal with measurable progress, so you can see the change occur. How will you see when you reach your goal? Be specific! "I want to read 3 chapter books of 100 pages on my own before my birthday" shows the specific target to be measure. "I want to be a good reader" is not as measurable.
Establish concrete criteria for measuring progress toward the attainment of each goal you set. When you measure your progress, you stay on track, reach your target dates, and experience the exhilaration of achievement that spurs you on to continued effort required to reach your goals.

Attainable
When you identify goals that are most important to you, you begin to figure out ways you can make them come true. You develop that attitudes, abilities, skills, and financial capacity to reach them. Your begin seeing previously overlooked opportunities to bring yourself closer to the achievement of your goals.
Goals you set which are too far out of your reach, you probably won't commit to doing. Although you may start with the best of intentions, the knowledge that it's too much for you means your subconscious will keep reminding you of this fact and will stop you from even giving it your best.
A goal needs to stretch you slightly so you feel you can do it and it will need a real commitment from you. For instance, if you aim to lose 20lbs in one week, we all know that isn't achievable. But setting a goal to loose 1lb and when you've achieved that, aiming to lose a further 1lb, will keep it achievable for you.
The feeling of success which this brings helps you to remain motivated.

Realistic
This is not a synonym for "easy." Realistic, in this case, means "do-able." It means that the learning curve is not a vertical slope; that the skills needed to do the work are available; that the project fits with the overall strategy and goals of the organization. A realistic project may push the skills and knowledge of the people working on it but it shouldn't break them.
Devise a plan or a way of getting there which makes the goal realistic. The goal needs to be realistic for you and where you are at the moment. A goal of never again eating sweets, cakes, crisps and chocolate may not be realistic for someone who really enjoys these foods.
For instance, it may be more realistic to set a goal of eating a piece of fruit each day instead of one sweet item. You can then choose to work towards reducing the amount of sweet products gradually as and when this feels realistic for you.
Be sure to set goals that you can attain with some effort! Too difficult and you set the stage for failure, but too low sends the message that you aren't very capable. Set the bar high enough for a satisfying achievement!

Timely
Set a timeframe for the goal: for next week, in three months, by fifth grade. Putting an end point on your goal gives you a clear target to work towards.
If you don't set a time, the commitment is too vague. It tends not to happen because you feel you can start at any time. Without a time limit, there's no urgency to start taking action now.
Time must be measurable, attainable and realistic.

Everyone will benefit from goals and objectives if they are SMART. SMART, is the instrument to apply in setting your goals and objectives.
