For test managers, consultants, and information technology professionals preparing to take the International Software Testing Qualifications Board (ISTQB) Certified Tester Expert Level exam, this guide covers its "Improving the Test Process" module and describes test process improvement and the human factors involved. It provides information on the exam, then outlines the context for test improvement; an overview of the improvement process and approaches; model-based and analytical-based improvement; selecting approaches; the details of the improvement process; the organization, individual roles and staffing, and the skills of the test process improver/assessor; managing change; critical success factors; and adapting to different life cycle models. Multiple-choice questions are provided in each chapter. Bath and Veenendaal, consultants who have experience in software testing and quality, are co-authors of the ISTQB Expert Level syllabus. Distributed by O'Reilly Media. Annotation ©2014 Ringgold, Inc., Portland, OR (protoview.com)

This book covers the syllabus for the Improving the Test Process module of the International Software Testing Qualifications Board (ISTQB) Expert Level exam.

To obtain certification as a professional tester at the Expert Level, candidates may choose to take a course given by an ISTQB accredited training provider and then sit for the exam. Experience shows that many candidates who choose this path still require a reference book that covers the course. There are also many IT professionals who choose self-study as the most appropriate route toward certification.

This book can be used both as a preparation guide for those planning to take the ISTQB Expert Level certification exam and as a practical guide for experienced testing professionals who want to develop their skills in improving test processes.
