Abstract
Capability Maturity Model Integration (CMMI) has been widely used in recent years. Adopting CMMI helps software vendors improve their software development ability, lower costs, reduce cycle time, and insure high quality products. It is also advantageous when facing competitors from China and other countries. However, most software companies in Taiwan belong to CMMI Level 1 or Level 2. The key problems are as follows: (1) CMMI is a formidable document. Its size alone makes it hard to comprehend and use for process improvement. (2) There are few tools and methodologies to support Levels 3 and 4. Therefore, we focus on process areas at CMMI Levels 3 and 4 and present related tools to support them.
First, we reinterpret the CMMI maturity model and identify our target process areas (i.e. Organizational Process Definition, Organizational Process Focus, Organization Training, Organizational Process Performance, and Quantitative Project Management). Based on these five process areas, we then propose a CMMI support architecture for Levels 3 and 4.
Our CMMI Levels 3 and 4 Support Architecture presents four components that support our target process areas. We implement a system prototype that has three main components, namely: process modeling, process simulation and process analysis. It enables quantitative evaluation of software processes and facilitates comparison of different process designs. These functions totally support the spirit of Levels 3 and 4, i.e. process definition and quantitative management.
We believe that our architecture and prototype support target process areas because we have accomplished most of the specific goals and specific practices in each process area. That is, we provide a tool to help software vendors move to higher levels of CMMI.
