The CMMI model is used for improving the maturity of company processes, mainly in software organizations. But the model says that CMMI can be used also in other engineering contexts, such as mechanical, electrical etc. Does anyone know about companies that have been evaluated in contexts other than software?
As you have stated, the CMMI for Development (CMMI-DEV) is useful for systems engineering, hardware engineering, and software engineering. Over the past 20 to 30 years, it has been primarily software organizations that have been implementing maturity models. But these models do apply in other contexts. In point of fact, I have been working with a client for over a year that just performs systems engineering and we are using the CMMI-DEV. We are currently planning their ML 3 SCAMPI A for early 2009. There is no software development involved in the scope of their appraisal. It has been an interesting experience to think outside of the software realm when interpreting the SPs and GPs, but it does work very nicely.
