Support

Support process areas cover the activities that support product development and maintenance. The Support process areas address processes that are used in the context of performing other processes. In general, the Support process areas address processes that are targeted toward the project and may address processes that apply more generally to the organization. For example, Process and Product Quality Assurance can be used with all the process areas to provide an objective evaluation of the processes and work products described in all the process areas.
The Support process areas of CMMI are as follows:
· Configuration Management
· Process and Product Quality Assurance
· Measurement and Analysis
· Decision Analysis and Resolution
· Causal Analysis and Resolution

Engineering

Engineering process areas cover the development and maintenance activities that are shared across engineering disciplines. The Engineering process areas were written using general engineering terminology so that any technical discipline involved in the product development process (e.g., software engineering or mechanical engineering) can use them for process improvement.
The Engineering process areas also integrate the processes associated with different engineering disciplines into a single product development process, supporting a product-oriented process improvement strategy. Such a strategy targets essential business objectives rather than specific technical disciplines. This approach to processes effectively avoids the tendency toward an organizational “stovepipe” mentality.
The Engineering process areas apply to the development of any product or service in the development domain (e.g., software products, hardware products, services, or processes).
The technical foundation for IPPD is grounded in a robust systems engineering approach that encompasses development in the context of the phases of the product’s life. The Engineering process areas provide this technical foundation. The implementation of IPPD is further addressed through amplifications to specific practices in the Engineering process areas that emphasize concurrent development and focus on all phases of the product’s life.
The Engineering process areas of CMMI are as follows:
· Requirements Development
· Requirements Management
· Technical Solution
· Product Integration
· Verification
· Validation

Project Management

Project Management process areas cover the project management activities related to planning, monitoring, and controlling the project.
The Project Management process areas of CMMI are as follows:
· Project Planning
· Project Monitoring and Control
· Supplier Agreement Management
· Integrated Project Management +IPPD

· Risk Management
· Quantitative Project Management
Integrated Project Management (IPM) has one goal that applies only when using CMMI with the IPPD group of additions.

Process Management

Process Management process areas contain the cross-project activities related to defining, planning, deploying, implementing, monitoring, controlling, appraising, measuring, and improving processes.
The Process Management process areas of CMMI are as follows:
· Organizational Process Focus
· Organizational Process Definition +IPPD
· Organizational Training
· Organizational Process Performance
· Organizational Innovation and Deployment
Organizational Process Definition (OPD) has one goal that applies only when using CMMI with the IPPD group of additions.

Four Categories of CMMI Process Areas

Process areas can be grouped into four categories:
· Process Management
· Project Management
· Engineering
· Support
Although we are grouping process areas this way to discuss their interactions, process areas often interact and have an effect on one another regardless of their defined group. For example, the Decision Analysis and Resolution process area provides specific practices to address the formal evaluation that is used in the Technical Solution process area for selecting a technical solution from alternative solutions. Technical Solution is an Engineering process area and Decision Analysis and Resolution is a Support process area.Being aware of the interactions that exist among CMMI process areas and which process areas are Basic and Advanced will help you apply CMMI in a useful and productive way. The following sections describe the interactions of process areas within the categories and only briefly describe the interactions among process areas in other categories. Interactions among process areas that belong to different categories are described in references within the Related Process Areas section of the process areas in Part Two.
