The analysis of the initial data set provides critical new information for the
overall planning of the appraisal and forms the basis for the detailed data
collection plan that must be developed before the on-site data collection
begins. The analysis of initial objective evidence at this stage is focused
primarily on the adequacy and completeness of information and the
implications for future data collection. The results of this analysis will be the
primary basis for determining the extent to which the appraisal will be one of
verification or discovery.
• Examine the initial set of objective evidence provided by the
organizational unit.
• Determine the extent to which additional information is needed for
adequate coverage of model practices.
Information provided by the organizational unit must be detailed enough to
understand the extent to which each type of objective evidence (direct
artifacts, indirect artifacts, and affirmations) is available for each process
instantiation, for each model practice within the scope of the appraisal. This
initial review of objective evidence identifies model practices for which the
team has
• strong objective evidence
• no objective evidence
• conflicting objective evidence
• anomalous objective evidence
• insufficient objective evidence
Key documents are identified that can be used to gain insight regarding a
number of model practices. These are potential high-leverage documents that
may be good candidates for pre-on-site review by team members.
Review the initial objective evidence with members of the engineering
process group.
