The random selection process does not guarantee that all defined subgroups will be represented in the appraisal.

The random selection process does not guarantee that all defined subgroups will be represented in the appraisal. There is no reasonable rationale for the omission of one or more subgroups. If different subgroups within an Organizational Unit are identified by applying the sampling factors, what is the justification for overlooking some of those subgroups and still determine a Maturity Level rating for that Organizational Unit.

 

The random sampling description in the MDD and algorithm have been updated to cover all defined in-scope subgroups are represented in the random sample. The scoping sections in the MDD have also been significantly updated to ensure clarity around the scoping and sampling requirements. In addition, the random sampling generates the minimum sample required for a CMMI appraisal. The primary driving factors in appraisals are still the business and appraisal objectives as determined by the Sponsor, with the guidance and review with the LA. The decision to go beyond the minimum sampling is still at the discretion of the Sponsor and LA, in accordance with MDD requirements. Lead Appraiser good judgement is still assumed and required to ensure coverage.
