Improvement of Software Testing Processes With Test Maturity Model Integration

ABSTRACT In this study, a maturity‐level determination and assessment method developed for companies operating in the software industry to perform TMMi Levels 2 and 3 assessments in‐house, with the goal of improving testing processes, is presented. With this method, it is aimed to help companies to conduct their own self‐assessments and improve their testing processes before participating in high‐budget audits. The validity of this method was tested in practice for TMMi Levels 2 and 3 assessments. Companies can prepare for a formal TMMi audit by using the test maturity‐level determination methodology developed in this study, or they can simply improve their processes to produce higher quality products. Additionally, if they already have TMMi certification, they can regularly self‐audit to ensure continuity and compliance. Demonstrating how TMMi can be applied in practice and providing a guide to test process maturity determination are key contributions of this work.
