SPI (Software Process Improvement) is increasingly applied methodology for the improvement of the software development. The practical capability level assessment using CMMI (Capability Maturity Model Integration) is conducted for the business processes within the specific software organization. The overall organization maturity level could be represented in a form of different reports including graphic diagrams. Usage of the SCT based generator enables flexibility in specifying parameters of maturity level assessment as well as producing different forms of customized reports.
