This tutorial deals with the TPI-model, which is based on current state-of-the-art test process improvement practices. The model gives practical guidelines for assessing the maturity level of testing in an organisation and for step by step improvement of the process. Since the appearance of the book "Test Process Improvement: a practical step-by-step guide to structured testing" (by Tim Koomen and Martin Pol) in May ĉ99, the model is rapidly becoming an international standard for improving test processes, used in numerous countries like the United States, most European Community countries, Australia, South Africa, Mexico, Columbia, China and India. The model is frequently used to help an organisation meet the test requirements at CMM level 3.
Also included in the tutorial is a general description of the application of model, which deals with how to implement and how to consolidate the improvements.
