Capability Maturity Model Integration is a basic framework designed for collaborative efforts to provide the best practice for the managing, measuring and monitoring the various software development processes. The requirement to build the CMM Integration is to get the product improved and in order to do so, the process of development to be improved. By improving the various processes during the development of the product, the emphasis will be to reduce the redundancy in the code during the development, the complexity in the development process during the design and the development phase and to see the overall reduction in the development cost. This paper gives the brief overview of the industry requirements and its need to have CMMI, its specification and the various levels.
