Level 3: Defined

At Level 3, a software development organization has a well-defined software engineering approach as well as a project management framework. Here, the processes are well documented and communicated across the organization through standards and training. Raynus says, "If the repeatable level defines what to do and who should do it, the defined level specifies when to do it and how to do it" [6].

Level 4 organizations understand and practice statistical quality control.
