Could you please answer the following questions about CMMI:
1- Are configuration action proposal and configuration improvement proposal direct artifacts if I try to implement the Specific Practice SP1.1 of the Process Area CM (Configuration Management)?
2- Are examples of software process architecture include: object-oriented model, unified model, and waterfall model?
CM.SP1.1 asks us to "Identify Configuration Items" and is part of Generic Goal 1 "Establish Baselines." I'm not sure what a "Configuration Action Proposal" or a "Configuration Improvement Proposal" are, but they sound like "Organizational" work products, and not project-level work products. SP1.1 is looking, literally, for a list of work products that we think are going to be part of our project. Examples include: product specs, requirements, process diagrams, drawings, test cases, test results . . . ."
Software Process Architecture, if I understand your question, defines the process framework that will be used to develop software. OOD, RUP, and Waterfall are all examples of PART of that (Life cycle models) but probably don't include a lot of items that should be part of the process (customer commitment to requirements, PPQA-type audits, peer reviews . . . ). So RUP is a subset of the required architecture, but not the entire process architecture.
