requires a trained and experienced Lead Appraiser who provides CMMI® training and administers a self-appraisal in a group setting with selected organization members. The purpose of the MSA is to ensure that an organization understands the meaning and intent of the model and to provide an independent validation of the self-appraisal results. Accuracy of MSA findings tends to be fair, with the cost and organization disruption being low. The MSA is quite useful as an initial organization activity to provide understanding of the model and the organization’s processes at a relatively low cost.
