Guidance
When using the staged representation of a CMMI model, the team may derive
the satisfaction of PAs from the set of goal satisfaction judgments. Assigning
PA satisfaction ratings is an optional activity, selected at the discretion of the
appraisal sponsor and documented in the appraisal input.
Rate the satisfaction of each PA in the scope of the appraisal based on the
ratings of the goals within each PA, if this rating option was selected during
planning.
PAs may be assigned rating values of Satisfied, Unsatisfied, Not Applicable,
or Not Rated.
A PA is rated Satisfied if and only if all of its specific goals and generic goals
are rated Satisfied.
If even one of the goals in a PA is rated Unsatisfied, then the PA is rated
Unsatisfied.
When a PA is determined to be outside of the organizational unit’s scope of
work, the PA is designated as Not Applicable and is not rated. The
identification of a PA as Not Applicable must occur during the planning of the
appraisal.
When a PA is outside of the appraisal scope, or if the associated set of
objective evidence does not meet the defined criteria for sufficient data
coverage, the PA is designated as Not Rated and is not rated. The criteria for
sufficient data coverage are described in activity 2.2.1, Verify Objective
Evidence.
A profile to summarize the satisfaction of goals may be created to provide
further insight about the rating outcomes. Where a PA is rated as Unsatisfied,
this more detailed view of the rating outcomes may provide focus and
visibility at a lower level of detail.
PA satisfaction is a direct function of goal satisfaction. A PA is rated as
Satisfied if every goal contained in the PA is rated as Satisfied. A PA is rated
as Unsatisfied if any goal is rated as Unsatisfied. This ensures that one or
more weaknesses exist that serve to explain why the goal and therefore the PA
are not satisfied.
PA ratings need not be reported to appraisal participants, if the sponsor does
not wish to disclose these results. However, a documented output from this
rating activity, if it is performed, is a required component in the Appraisal
Record.
