Our organization is CMMI Maturity Level 3 Ver 1.2 certified. Our delivery teams are going to implement CMMI practices soon. I did see the processes of the organization and though all the roles appeared from project leader to developer to manager, except for documentation teams. In the same context, I am very curious to see if there are any set of practices to be followed for the documentation department in CMMI as all the processes at CMMI ML2, ML3 are specific to project management, engineering, support, organization areas.
Your question actually raises some other questions:
- What are the roles and responsibilities of your documentation teams and documentation department?
- If this group of people is responsible for the technical documentation (e.g. requirements, design, etc.) and the user documentation, how and why were they excluded from your ML 3 SCAMPI A?
- How are the delivery teams different from the organization that achieved Maturity Level 3?
What is puzzling with your question is that REQM, RD, TS, PI, and CM cover the different aspects of writing and controlling the various documents associated with designing, developing, maintaining, operating, using, and deploying products. And then VER covers the inspection/review of the documents before placing them in the baseline and controlling them with CM.
It does appear from your description that your organization omitted the documentation people as a process role from your process documentation. In my opinion, at a minimum, your PPQA audits should have identified this omission long before your SCAMPI A appraisal. Then your Lead Appraiser should have identified this gap during the appraisal planning process before the SCAMPI A and should have taken steps to address the gap or postponed your appraisal until the documentation group was included in the scope. Since your documentation group was apparently not included in the scope of your appraisal, this oversight also calls into question your Lead Appraiser’s credentials and quite possibly the validity of your SCAMPI A results.
The bottom line, in my opinion, and based on only what you stated, your documentation group should have been included in the scope of your ML 3 SCAMPI A. Even if all they do is Document Configuration Control (which would be covered under CM) or Document Quality Assurance (which would be covered under PPQA).
The answers to my above questions could provide additional information that would change my opinion.
