In the chart on above it is important to note that some companies and some teams are further along than. I would say that we are measuring the software s evolution in two distinct ways. In cmmi models with a staged representation, there are five maturity levels designated by the numbers 1 through 5. Cmm was developed at the software engineering institute in the late 80s. All maturity models present several levels against which different areas are assessed. Initial, repeatable, defined, managed and optimizing. Although this model is applied to the software development process, eventually it is used for other processes as well like qa and testing.

Cmm capability maturity model a process developed by sei in 1986 to help improve, over time, the application of an organizations supporting software technologies. Cmmi maturity levels a maturity level is a welldefined evolutionary plateau toward achieving a mature software process. It is structured into maturity levels that range from level 1 to level 5. The model describes a fivelevel evolutionary path of increasingly organized and systematically more mature processes. A maturity level is a welldefined evolutionary plateau toward achieving a mature software process. They also help an organisation prioritise its improvement efforts. If software s maturity cannot simply be measured by how long it has been on the market, yet time in the market is clearly an indicator of how mature a piece of software is, then what is the factor that we are measuring here. As we documented the behaviors, processes, and activities that constitute defined, managed, and repeatable best practices for localization, we found that most organizations pass through four stages of maturity before reaching the ideal process see figure 1. Maturity levels represent a staged path for an organizations performance and process improvement efforts based on predefined sets of practice areas. At this level, the entire software development process is not only defined but is managed in a proactive fashion. Test maturity model tmm is fairly a new concept compared to compatibility maturity model cmm but the main goal of both models remains the same i.
