Achieving the Goals of TMMi Levels 2 and 3 has the benefits of putting into place a technical, managerial and staffing infrastructure capable of thorough testing and providing support for test process improvement.
With this infrastructure in place, testing can become a measured process to encourage further growth and accomplishment. In TMMi Level 4 organisations, testing is a thoroughly defined, well-founded and measurable process.
Testing is perceived as evaluation, consisting of all life cycle activities concerned with checking products and related work products. Peer reviews as a defect detection technique is transformed into a product quality measurement technique in line with the Process Area Product Quality Evaluation.
TMMi level 4 also covers establishing a coordinated test approach between peer reviews (static testing) and dynamic testing and the usage of peer reviews results and data to optimise the test approach with both aiming at making testing more effective and more efficient.
Peer reviews are now fully integrated with the dynamic testing process, being part of the test strategy, test plan and test approach.
There are 3 Process Areas in this Level.
