Introduction:

Scorecards are becoming an increasingly popular method for identifying the elements necessary for success in a specific category of Maintenance and Reliability, weighting their importance and providing an objective score to measure performance. Scorecards are available for evaluating the effectiveness of work and stores management processes (Reliability Magazine Volume 10, Issue 3). During 2005, Jack Nicholas introduced a comprehensive RCM scorecard to measure the extent and compliance of a RCM program. The Reliability Program Scorecard adds to this body of knowledge with a list of the principal elements of a comprehensive reliability program and proposed weights. The Reliability Scorecard is presented in a spreadsheet format that is easily optimized for specific applications.

A draft version of the Reliability Scorecard was thoroughly discussed during four 90-minute workshops conducted at IMC 2005, sponsored by reliabilityweb.com. Additions and modifications suggested by workshop participants were incorporated into a second draft circulated for comment. This first version incorporates all comments and suggestions received to date.  

Scorecard Objective:

The Reliability Scorecard is the result of a several year effort to describe the total scope, content and effectiveness of a comprehensive reliability program. The scorecard is intended for use to define elements that should be considered for inclusion in a new reliability program as well as provide a basis for auditing the content and effectiveness of an existing reliability program.

Scorecard Overall Description and Content:

The scorecard, in spreadsheet format, divides a comprehensive reliability program into twelve program categories. The scorecard consists of two worksheets as follows:

1.      Category Summary

2. Detailed Scorecard

The first worksheet of the Scorecard, Category Summary, lists the twelve program categories and the highest weighted elements within each category. The second column on the Category Summary, Element Weight - %, calculates automatically through the Detailed Scorecard (second worksheet) from Category Weight - % entered manually in the third column. This will be explained in detail later.

Note: Elements in each of the twelve categories listed on the Summary worksheet have been sorted by weight in descending order. This is intended to emphasize relative priorities of the elements listed. It results in a different sequence than will be found on the Detailed Scorecard. If there is any question regarding origin, the element weight cell will identify the row in the Detailed Scorecard.

It also should be noted that the wording of elements on the Category Summary may differ slightly from wording on the Detailed Scorecard. The description and quartile ranking on the Detailed Scorecard provides an assessment of effectiveness. The Element Weight listed on the Category Summary is the maximum. If a program has high plant and system reliability, optimum maintenance costs, minimum emergency work, to name three elements, the Element Weight listed on the Category Summary is the contribution to total program effectiveness. Taking the logic further, the Category Summary implies that a reliability program with the elements listed, performing at best practice levels, constitutes almost 80% of an optimum program.

The second worksheet is the Detailed Scorecard. The Detailed Scorecard lists elements of each of the twelve program categories in ten columns. The leftmost column lists individual elements that are considered necessary for each program category. The next three columns, from left to right, define necessity, comparative metrics and any additional requirements such as a charter or procedure that must be published to meet requirements.

The fifth and sixth columns assign percentage weights for each element within the category. Individual weights for each element within the category are manually entered as a percentage of 100% in the fifth column.  Element weights within the reliability program as a whole are automatically calculated based on the relative weights entered in the third, Category Weight, column on the Category Summary (first worksheet) and repeated in the top row of each category.

Note: The spreadsheet is constructed such that changing a Category Weight (third column) on the first worksheet, Category Summary, will apply the change to the corresponding category in the Detailed Scorecard. All program element weights within the scorecard category automatically recalculate using the relative weights in the fifth column of the Detailed Scorecard. The only requirement when adjusting either category weights in the Summary sheet or element weights in the Detailed Scorecard is to manually maintain the total at 100% shown in the last line of the Category Weight column in the Summary, top line of the Element Weight column in each category on the Detailed Scorecard. 

To provide a check on the math and formulas, the Program Weight listed in the top row of each category in the Detailed Scorecard, shown as a percentage, is the value transmitted from the Category Summary. The last row in the same column, expressed as a decimal, sums the individual program weights for each element within the category. If the formulas and entries are correct the two numbers (absolute) will be identical.

The four rightmost columns on the Detailed Scorecard denote quartile spread between the best performers and the rest. As an example, first quartile performers should have an overall plant, system and equipment availability greater than 95%. An overall availability less than 70% indicates fourth quartile performance. It is recognized that there may be adjustments required for specific processes and industry groups.   

Several essential elements of a total maintenance program such as Work and Stores Management processes are not listed beyond metrics that are key to the effectiveness of a reliability program. For other essential elements such as RCM and RCFA, the scorecard only asks whether the program is in place and effective. In both cases, details necessary to evaluate the completeness of these processes / programs and assess their effectiveness are available in literature on the subject. The details will be necessary to assign partial scores indicating the completeness and effectiveness of the program.

An abbreviated glossary from the draft fourth edition of the Asset Optimization Handbook is located directly below this description to answer any questions regarding terminology or how a specific term is used within the scorecard.

Use of the Scorecard

The scorecard is yours and can be used in any way you wish. As one way to get started you might begin as follows:

1.      Review the Category Summary worksheet to determine if all the elements you consider important to your site are listed.

During the preparation of the scorecard, and especially during the workshops conducted at IMC 2005, it has been very apparent that a wide diversity of opinions exist on the composition of a reliability program and weight of elements depending on the specific facility and type of process. Hopefully this scorecard will provide you with a good starting point.

2.      Review the Detailed Scorecard, second worksheet. Are there any elements listed on the Detailed Scorecard that are important to your site but don’t appear on the Detailed Scorecard or Category Summary? You can easily add to the Scorecard or Summary

It is assumed that that you are sufficiently competent with Excel to be able to add rows on both the Summary and Scorecard, insert the correct formulas in the weight cells and the necessary formulas on the Summary and Detailed Scorecard to link the two. If there is any doubt, you can view current cell formulas and simply copy an existing cell formula into an added cell and revise the references as necessary.

3.      With all the important elements listed on the Category Summary, adjust the weights to obtain more or less the importance you consider applicable for your facility. You may have to adjust weights on the Detailed Scorecard as well to obtain the results you are seeking.

Remember, to make the weights work you must manually adjust the weights of each category on the Category Summary and individual elements on the Detailed Scorecard to total 100%. 

Acknowledgements
