This book provides a practical view of how to use requirements effectively. It contains several complete examples and practical material, and this way ideally complements Bertrand Meyer’s “Handbook of Requirements and Business Analysis”. It includes implementations of the important ideas from this handbook, concrete and directly usable, such as professional templates, principles and rules implementations, or a detailed list of possible stakeholders. It not only details the principles of the PEGS (Project – Environment – Goals – System) approach, but also offers a lot of illustrations, concrete cases, examples of implementation, practical advice, and materials to adopt the approach efficiently.


It thus addresses several kinds of readers: First, industry professionals looking for practical materials and guidelines to help them apply good practices and principles to handle modern requirements and business analysis. Second, students eager to exercise and learn modern practices of requirements engineering and business analysis. And third, lecturers looking for complete case studies to discuss with their students, as well as exercise solutions, examples and discussions around modern requirements and business analysis.


Almost all the practical materials described in this book are available on a related companion website.
