Every maturity level is shown by the implementation of various groups of process areas that assist the

of an organization’s software processes are believed to improve as the organization scales up to these
five levels. While not rigorous, the empirical evidence to date supports this belief." The five maturity
levels are as described below:
1. Level 1- Initial: The starting phase for using a new process. At this level, the processes are not
