Agile methodologies define specific roles for each project stakeholder. Learning how to play these roles and navigate agile's stakeholders can prove bewildering to new practitioners, impeding their success with agile. This book guides agile practitioners in understanding their roles and immediately applying pragmatic agile practices that are proven to work. Designed for team members working with any agile methodology, it shows how to apply the specific agile best practices most closely associated with success in each role, and become far more effective advocates for agile throughout their organizations. Leading agile consultant Venkat Subramaniam first helps agile team members gain momentum for core agile practices, including stories, estimation, and planning, and offers expert guidance on scaling agile to larger projects. Next, he demonstrates how to sustain the pace of agility by applying evolutionary design and architecture, test-driven design, mock objects, refactoring, continuous integration, and other innovative techniques. The book concludes with a full chapter of case studies, many drawn from the author's own consulting experience.
