reusing Pre ious Appraisal results
Organizations often want to use previous appraisal results when beginning a CMMI
initiative. This has proven to be extremely diffi cult for many organizations, and in
our experience, has led to inappropriate actions. By previous appraisals, we mean
results from non-CMMI appraisals (CBA IPIs, SCEs, EIA 732, etc.). The reason

288 n Interpreting the CMMI
Different levels of detail in appraisal approach
Some appraisals did not consider institutionalization of practices
Not all weaknesses were documented
Don??™t assume that since you did not have a weakness, that you have a strength.
Often only level-threatening weaknesses are documented. A threat to a level is
only known after hours of consensus and team negotiations.
