The Test Maturity Model integration (TMMi) provides a framework for assessing the maturity of the test processes in an organisation. Level 5 is the highest level of certification under the TMMi scheme, which is developed and managed by the TMMi Foundation.
At TMMi level 4 organisations, testing is a thoroughly defined, well-founded and measurable process. Testing is perceived as evaluation; it consists of all lifecycle activities concerned with checking products and related work products. An organisation-wide test measurement program will be put into place that can be used to evaluate the quality of the testing process, to assess productivity, and to monitor improvements. Measures are incorporated into the organisation's measurement repository to support fact-based decision making. A test measurement programme also supports predictions relating to test performance and cost.
With respect to product quality, the presence of a measurement programme allows an organisation to implement a product quality evaluation process by defining quality needs, quality attributes and quality metrics. 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.
To date, three Malaysian organisations have obtained TMMi certifications – Malaysian Software Testing Board (Level 5), Custommedia (Level 4) and Mesiniaga Berhad (Level 3). Custommedia is currently preparing to go up to TMMi Level 5 certification.
