Process improvement is just like continuous improvement.
We can never reach the perfect level. From this tutorial, we willl be able to learn CMM that is continuously evolving and about the improving model where the focus always lies on doing better.
Our final reach must always exceed our grasp.
Definitions may vary but the mature processes are generally known to be:
Poor but the mature processes are just as bad as no maturity at all.
CMM helps in solving the maturity problems by defining a set of practices and also providing a general framework for improving them. The focus of CMM mainly lies on identifying the key process areas and also the exemplary practices that may comprise of disciplined software process.
In an immature organization we can see the following characteristics:
In contrast, the characteristics of a mature organization are as follows:
CMM Integration project was developed to sort out the problems of using multiple CMM's. CMMI product teams goal was to combine the three Source Models into one single improvement framework for the organizations which are pursuing enterprise-wide process improvement. The above mentioned three Source Models are:
Integrated Product Development Capability Maturity Model (IPD-CMM) v0.98.
Capability Maturity Model for Software (SW-CMM) - v2.0 Draft C.
Electronic Industries Alliance Interim Standard (EIA/IS) - 731 Systems Engineering.
CMM is just a reference model of matured practices in a specified discipline like Systems Engineering CMM, People CMM,Software CMM, Software Acquisition CMM etc., but they were difficult to integrate when needed.
CMMI is the next version or successor of the CMM and it evolved into a more matured set of guidelines.It had been built combining the best components of the individual disciplines of CMM(Software CMM, People CMM, etc.). CMMI can be applied to people management, software development, product manufacturing,etc.
CMM only describes about the software engineering where as CMMI describes both software and system engineering. CMMI also helps in incorporating the Integrated Process and Product Development from the supplier sourcing.
The objectives of CMMI are very clear. They are as follows:
