Test Maturity Model Integration (TMMi)

For the past decade, the software industry has put substantial effort in improving the quality of its products. This has been a difficult job, since the size and complexity of software increases rapidly while customers and users are becoming more and more demanding. Despite encouraging results with various quality improvement approaches, the software industry is still far from zero defects. To improve product quality, the software industry has much focused on improving their development processes. A guideline that has been widely used to improve the development processes is the Capability Maturity Model. The Capability Maturity Model (CMM) and its’ successor the Capability Maturity Model Integration (CMMI) are often regarded as the industry standard for software process improvement. Despite the fact that testing often accounts for at least 30-40% of the total project costs, only limited attention is given to testing in the various software process improvement models such as the CMM and the CMMI. As an answer, the testing community has created its complementary improvement models. This document describes the Test Maturity Model Integration (TMMi). The TMMi is a detailed model for test process improvement and is positioned as being complementary to the CMMI.
