Activity
Description
Required
Practices
Parameters
and Limits
The appraisal team must establish a clear understanding of the practices
implemented in the organization. Typically, the organization provides a set of
objective evidence at the beginning of the appraisal process, and the team sets
out to verify the instances where those practices are implemented. For
practices reflecting project-level activities, the team must observe that each
selected project in the organizational unit has evidence of implementation. For
practices reflecting organization-level activities, the team must understand the
organization-level implementation as well as any activities involving the
projects that indicate the implementation of the practice.
• Verify the appropriateness of direct artifacts provided by each
instantiation for practices within the model scope of the appraisal.
• Verify the appropriateness of indirect artifacts provided by each
instantiation for practices within the model scope of the appraisal.
• Verify the appropriateness of affirmations provided by each instantiation
for practices within the model scope of the appraisal.
• Verify that the implementation of each model practice is supported by
direct artifacts for each instantiation, and corroborated by indirect artifacts
or affirmations.
• Obtain face-to-face affirmations for (1) at least one instantiation for each
model practice in the scope of the appraisal, or (2) at least 50% of the
practices corresponding to each specific and generic goal for each
instantiation.
• Generate statements describing gaps in the organizational unit’s implemented
practices relative to practices defined in the reference model.
For practices implemented at the project level, direct and indirect indicators of
practice implementation must be examined for every project sampled to
represent the organizational unit being appraised.
For practices implemented at the organization level, direct and indirect
indicators of practice implementation are examined in reference to the
organizational unit within the scope of the appraisal, and not necessarily for
each project sampled. Aspects of the practice that are implemented at the
project level must be investigated for every project sampled to represent the
organizational unit.
One or more direct artifacts will be needed to verify implementation of each
model practice. Indirect indicators can include either artifacts or affirmations.
A description of these indicator types is contained in activity 1.4.3, Obtain
Initial Objective Evidence.
Coverage criteria for face-to-face affirmations are focused at the goal and
organizational unit level.
