S3m - Introduction 

The Software Maintenance Maturity Model 





The book



The Software Maintenance Maturity Model (S3M®) is a maturity model aimed at software maintenance organisations and covers such processes as transition, corrective, adaptive, perfective, support and many more. The structure of the model is similar to that of the Software CMM, the contents of the S3M, however, are key process areas needed for maturing software maintenance organisations aimed at small changes, not projects.

Currently, the S3M is in use in several small, medium-sized and large organizations that are applying the S3M to improve their software maintenance processes and organisation(s).

The model, currently at version 3, is described in a number of publications. Maturity level 0,1 and 2 practices can be downloaded for free

Enjoy, S3M.
