2.6 The importance of the model elements for Capability
Rating of Capability Level 1
As shown in the previous section the Base Practices are of major importance. They are used to determine the rating of GP1.1.1 and PA1.1. The output work products are not rated explicitly.
If it is hard to decide for either Capability Level zero or one the assessors may consider:
- Because the Process Outcomes have a slightly higher importance then the Base Practices (see how GP1.1.1 is phrased: “Achieve the process outcomes”) one may check whether Process Outcomes have been highly impacted by particular Base Practices. This is the case if a Process Outcome is supported by one single Base Practice only and this Base Practice has severe weaknesses. If Process Outcomes are not achieved this may give a clearer perspective whether CL1 is achieved or not.
- You might take a closer look at the Process Purpose (see how PA1.1 is phrased: “the extent to which the process purpose is achieved”). The Process Purpose often highlights some aspects which may correspond to a subset of Base Practices and their ratings would then gain more emphasis.
Rating of Capability Level 2 and higher
The Generic Practices are at the center of attention. They are used to determine the rating of the Process Attributes. Generic Resources are not rated explicitly. If it is hard to decide between two Capability Levels one can compare the phrasing of a Process Attribute with the phrasing of its Generic Practices and derive different weightings of its Generic Practices.
