Climbing the Ladder: CMMI Level 3

This report details the attempt to form a complete workflow model for an ICT company in order to achieve a Capability Maturity Model Integration (CMMI) maturity rating of three. During this project, business processes across the company´s core and auxiliary sectors were documented and extended using modern enterprise modeling tools and a The Open Group Architectural Framework (TOGAF) methodology. Different challenges were encountered with regard to process customization and tool support for enterprise modeling. In particular, there were problems with the reuse of process models, the integration of different project management methodologies and the integration of the Rational Unified Process (RUP) development process framework that had to be solved. We report on these challenges and point out research directions that could help to improve the situation in the future.
