Systematic process improvement using ISO 9001:2000 and CMMI

4.2 CMMI ® 99
uous representation defines four process categories: engineering, project
management, process management, and support.
Although the PAs are grouped into categories, they interact in many
ways and those interactions must be kept in mind when their features are
discussed. Specific goals, associated specific practices, and a brief discussion
of each PA’s salient features are given next. For more details, refer to [2].
4.2.6.1 Engineering
The engineering PAs include these:
• Requirements Management (REQM);
• Requirements Development (RD);
• Technical Solution (TS);
• Product Integration (PI);
• Verification (VER);
• Validation (VAL).
These are the only PAs that contain both base and advanced specific
practices. Base practices, denoted as SP x.y-1, are required if capability level
1 is to be satisfied. The advanced practices, denoted as SP x.y-2 or SP x.y-3,
are associated with capability levels 2 and 3, respectively. As indicated
earlier, base and advanced practices are not distinguished in the staged
representation.
Requirements Management
The purpose of requirements management is to manage the requirements of the
project’s products and product components and to identify inconsistencies
between those requirements and the project’s plans and work products.
