To demonstrate how to use this model, let us look at two different scenarios. Scenario 1 is an electronic systems developer that wants to improve its product development processes using a continuous approach. Scenario 2 is a software development company that uses IPPD, has been using the Software CMM, and now wants to use CMMI. This company most recently has been rated at maturity level 3 using the Software CMM (version 1.1).
