The Art of Agile Development contains practical, down-to- earth guidance for anyone involved in or considering the agile method - and Extreme Programming in particular - to build reliable software. Agile development methods have become increasingly popular because too many software projects have failed to meet expected release dates, deliver the required features, or to match projected costs. This book provides no-nonsense advice on agile planning, development, delivery, and management taken from the authors' many years of experience. While plenty of books address the what and why of agile development, very few offer developers, managers, stakeholders and users the information they can apply directly.
