Setting up Criteria for Prioritization Analysis

Analysis criteria are the business goals that each asset is evaluated against when an asset prioritization analysis is conducted. Usually, you will use six or seven criteria such as safety, environment, quality, throughput, operating cost, and customer service.
 
The prioritization criteria are enterprise-wide, although you can define rule sets for groups of assets or sites. Criteria are typically developed by the key stakeholders and reflect overall business goals.
During an asset prioritization analysis, you will select a consequence for each criterion. The score for the selected consequence is assigned to the asset. The scores for all criteria are used to determine the asset’s priority.
After criteria have been determined, stakeholders decide if any of the criteria should be given more importance. This is done by setting the maximum score for each criterion. This is the highest score a criterion can attain during an analysis; the higher the score, the more critical the result of failure. For example, the criterion Safety might be given a maximum score of 40 points and Operating Cost only 10 points. Safety then contributes more points to the overall priority score and thus is a more important criterion.
As a general rule, safety and environment are given equal maximum scores, while the sum of all operating consequences is equal to the maximums for safety and environment.
The system comes with six criteria already defined. These are the most commonly used criteria for analyses. You can use all, some, or none of these criteria.
Criteria
Maximum Score
Safety
40
Environment
40
Quality
10
Throughput
10
Customer service
10
Operating cost
10
Notice that the maximum scores for operating consequence criteria (quality, throughput, customer service, and operating cost) sum to a total of 40 points.

Weighting Factors

You can assign weighting factors (whole numbers greater than 0) to analysis criteria to raise or lower the significance of individual criteria. The consequence score is multiplied by the weighting factor. For example:

To Define an Analysis Criterion

1.
From the Site window, select the Strategy Development view, Settings tab. Select the Prioritization tab and the Asset prioritization settings node in the tree.
Tip: You can also select the Administration menu, Strategy Development Settings, and then Asset Prioritization. The Asset Prioritization Settings dialog appears.
2.
Select the Analysis Criteria tab.
3.
Click New. The Assessment Criteria dialog appears.
4.
On the General tab, enter the following information:
Setting Name
Description
Assessment criteria
A meaningful name that identifies how the asset is to be evaluated. The criterion typically relates to your business goals.
Usage
Indicates whether the criterion is used with asset prioritization or asset condition analysis.
Rule set
Rule sets are used to apply selected consequence priority (condition) rules to specific groups of assets or sites. For example, when a rule set is assigned to an analysis, only the rule clauses that reference that rule set are used to calculate the asset’s consequence priority or condition.
If the analysis does not have a rule set, only rules that do not reference a rule set are used.
Sequence
The criteria sequence numbers control the order in which the criteria are presented throughout the analysis. A general rule is to order the criteria in the order of importance. Give the most important criterion sequence number 1 and so on.
Maximum score
Identifies the maximum score that can be assigned to a consequence for this criterion. Maximum score can be used to give weight to the criteria. More important criteria will have a higher maximum score.
Weighting factor
The weighting factor raises or lowers the significance of the criteria. The consequence score for the criterion is multiplied by the weighting factor. For example, a weighting factor of 2 on Operating Cost would double the score.
5.
Select the Analysis Criteria tab. For each consequence you wish to add, click New. The Criteria Consequence dialog appears:
6.
Enter the following information:
Setting Name
Description
Score
The score that will be given to assets that are assigned this consequence. Each consequence must have a unique score. More serious consequences should be given higher scores.
Description of consequence
A meaningful summary of the types of failures that can occur for an asset being assigned this consequence. For example, for the criterion Safety, a consequence of failure might be minor injury. You can describe this further by creating consequence examples and explanations in the table below.
7.
Be sure to add an explanation or example to each consequence criterion to help users when entering scores. For each explanation you need, click New. The Consequence Example dialog appears:
8.
Enter the following information:
Setting Name
Description
Sequence
Controls the order in which the consequence examples appear in the analysis worksheet.
Description
Specific examples of failures that can result in an asset being assigned this consequence. Use these examples during the analysis to help team members determine the score for an asset.
