CMMI stands for Capability Maturity Model Integration. It is a process improvement approach that provides companies with the essential elements of effective process. CMMI can serve as a good guide for process improvement across a project, organization or division.
CMMI was formed by using multiple previous CMM process. Below are the areas which CMMI addresses because of integrating with CMM process:-
Systems engineering: - This covers development of total systems. System engineers concentrate on converting customer needs to product solution and support them through out the product life cycle.
Software Engineering: - Software engineers concentrate on the application of systematic, disciplined, and quantifiable approaches to the development, operation, and maintenance of software.
Integrated Product and Process Development: - Integrated Product and Process Development (IPPD) is a systematic approach that achieves a timely collaboration of relevant stakeholders throughout the life of the product to better satisfy customer needs, expectations, and requirements. This section mostly concentrates on the integration part of the project for different processes. For instance it’s possible that your project is using services of some other third party component. In such situation the integration is a big task itself and if approached in a systematic manner can be handled with ease.
Software Acquisition: - Many times organization has to acquire products of other organization. Acquisition is itself a big step for any organization and if not handled in a proper manner means just calling for disaster.
