Software testing is an essential part of software development but many organizations regard it as an uncontrollable part of the process and find it difficult to take steps to improve it. In Test Process Improvement, Tim Koomen and Martin Pol give practical suggestions for improving the testing process in a gradual and controlled manner, with realistic goals in terms of quality, lead time and costs.

The book describes and explains the Test Process Improvement (TPI) model, tried and tested by numerous professional testers, which provides a structured framework to be used either for improving an existing test process or for developing a new process from scratch. The authors use their in-depth knowledge and extensive experience to provide practical guidance and a framework that enables the reader to adapt the model for use in his/her organization.

If you are involved in testing software systems and are aiming to implement a successful and structured process, you will find this book an invaluable resource.
