2.2.2 Characterize Implementation of Model Practices Activity Description Required Practices Parameters and Limits Once a critical mass of evidence on practice implementation has been verified, the team (or mini-team) turns to characterizing the implementation of model practices. For each practice in the model included in the selected scope, and each instance of expected use, the team will document a characterization of the extent to which the model practice (or an acceptable alternative) has been implemented. These project-level characterizations are then aggregated to the organizational unit level. Characterizations of practice implementation are used as a means to focus appraisal team effort on areas where professional judgment is needed, and to aid in reaching team consensus on the extent to which practices are implemented. • Characterize, for each instantiation, the extent to which reference model practices are implemented. • Aggregate practice implementation characterization values from the instantiation level to the organizational unit level. The following table summarizes rules for characterizing instantiation-level implementations of practices. Consensus of at least a subset of appraisal team members (e.g., mini-team members) is necessary for instantiation-level characterizations. Label Meaning Fully Implemented (FI) • The direct artifact is present and judged to be appropriate. • At least one indirect artifact and/or affirmation exists to confirm the implementation. • No substantial weaknesses were noted. Largely Implemented • The direct artifact is present and judged to be (LI) appropriate. • At least one indirect artifact and/or affirmation exists to confirm the implementation. Partially Implemented (PI) • One or more weaknesses were noted. • The direct artifact is absent or judged to be inadequate. • Artifacts or affirmations suggest that some aspects of the practice are implemented. • Weaknesses have been documented. Not Implemented (NI) • Any situation not covered above Continued on next page Page II-90 CMU/SEI-2001-HB-001
2.2.2 Characterize Implementation of Model Practices (continued) Parameters and Limits (continued) The following table summarizes rules for aggregating instantiation-level characterizations to derive organizational unit-level characterizations. Consensus of all members of the appraisal team is necessary for organizational unit-level characterizations. The column labeled “Condition” is the input condition—the practice implementation characterizations for the set of sampled projects. The column labeled “Outcome” is the resultant aggregated practice implementation characterization at the organizational unit level. Condition Outcome Remarks All X (e.g., all LI) X All instantiations have the same characterization. All (LI or FI) LI All instantiations are characterized LI or higher. Any PI, No NI LI or PI Team judgment is applied to choose LI or PI for the organizational unit. Any NI NI, PI, or LI Team judgment is applied to choose NI, PI, or LI for the organizational unit. Optional Practices Implementation Guidance While the initial characterization of practice implementation may be proposed by a mini-team or some subset of the team, the following selections are available: • Instantiation-level characterization of practice implementation can be reviewed by the entire team for consensus. • Team-wide review and consensus on practice implementation characterization can be reserved for the organizational unit level. • A mix of the two strategies above, tailored to match the learning curve of the team members or to reflect the prioritization of particular PAs, can be used. When the team is ready to perform the ratings, these characterizations serve to simplify the judgments. The team is then able to focus on the aggregation of weaknesses observed to determine the goal satisfaction ratings (explained in process 2.4). Situations where the project has not yet reached the appropriate point in time where the practice would be enacted are omitted from this characterization. The appraisal-planning activities are expected to prevent situations that severely limit the examples of actual implementation for any given practice.
