I would like to know what is the content of the Statement of Work and how does this document meet requirements of the CMMI?
As a best practice with definition questions, the first place to look is the CMMI Glossary. In this case there is a definition of Statement of Work (SOW) in the Glossary. “A description of contracted work required to complete a project.” In other words, the SOW contains the requirements for what you have to delivery to the customer. And there are varying levels of detail from SOW to SOW depending on the size, criticality, and nature of the work. For large government contracts, the SOW may also contain the Work Breakdown Structure (WBS) for the program/project as well. At a minimum, the SOW will contain the customer’s requirements that the organization will further develop. So the SOW supports RD and may also support PP.
