Extreme Programming Explained: Embrace Change
"In this completely revised introduction to Extreme Programming (XP), Kent Beck describes how to improve your software development by integrating these concepts into your daily development process. The first edition of Extreme Programming Explained is a classic. It won awards for its then-radical ideas for improving small-team development, such as having developers write automated tests for their own code and having the whole team plan weekly.

“In this second edition of Extreme Programming Explained, Kent Beck organizes and presents five years’ worth of experiences, growth, and change revolving around XP. If you are seriously interested in understanding how you and your team can start down the path of improvement with XP, you must read this book.”—Francesco Cirillo, Chief Executive Officer, XPLabs S.R.L. “The first edition of this book told us what XP was—it changed the way many of us think about software development. This second edition takes it farther and gives us a lot more of the ‘why’ of XP, the motivations and the principles behind the practices. This is great stuff. Armed with the ‘what’ and the ‘why,’ we can now all set out to confidently work on the ‘how’: how to run our projects better, and how to get agile techniques adopted in our organizations.”—Dave Thomas, The Pragmatic Programmers LLC “This book is dynamite! It was revolutionary when it first appeared a few years ago, and this new edition is equally profound. For those who insist on cookbook checklists, there’s an excellent chapter on ‘primary practices,’ but I urge you to begin by truly contemplating the meaning of the opening sentence in the first chapter of Kent Beck’s book: ‘XP is about social change.’ You should do whatever it takes to ensure that every IT professional and every IT manager—all the way up to the CIO—has a copy of Extreme Programming Explained on his or her desk.”—Ed Yourdon, author and consultant “XP is a powerful set of concepts for simplifying the process of software design, development, and testing. It is about minimalism and incrementalism, which are especially useful principles when tackling complex problems that require a balance of creativity and discipline.”—Michael A. Cusumano, Professor, MIT Sloan School of Management, and author of The Business of Software “Extreme Programming Explained is the work of a talented and passionate craftsman. Kent Beck has brought together a compelling collection of ideas about programming and management that deserves your full attention. My only beef is that our profession has gotten to a point where such common-sense ideas are labeled ‘extreme.’...”—Lou Mazzucchelli, Fellow, Cutter Business Technology Council“If your organization is ready for a change in the way it develops software, there’s the slow incremental approach, fixing things one by one, or the fast track, jumping feet first into Extreme Programming. Do not be frightened by the name, it is not that extreme at all. It is mostly good old recipes and common sense, nicely integrated together, getting rid of all the fat that has accumulated over the years.”—Philippe Kruchten, UBC, Vancouver, British Columbia“Sometimes revolutionaries get left behind as the movement they started takes on a life of its own. In this book, Kent Beck shows that he remains ahead of the curve, leading XP to its next level. Incorporating five years of feedback, this book takes a fresh look at what it takes to develop better software in less time and for less money. There are no silver bullets here, just a set of practical principles that, when used wisely, can lead to dramatic improvements in software development productivity.”—Mary Poppendieck, author of Lean Software Development: An Agile Toolkit “Kent Beck has revised his classic book based on five more years of applying and teaching XP. He shows how the path to XP is both easy and hard: It can be started with fewer practices, and yet it challenges teams to go farther than ever.”—William Wake, independent consultant “With new insights, wisdom from experience, and clearer explanations of the art of Extreme Programming, this edition of Beck’s classic will help many realize the dream of outstanding software development.”—Joshua Kerievsky, author of Refactoring to Patterns and Founder, Industrial Logic, Inc.“XP has changed the way our industry thinks about software development. Its brilliant simplicity, focused execution, and insistence on fact-based planning over speculation have set a new standard for software delivery.”—David Trowbridge, Architect, Microsoft CorporationAccountability. Transparency. Responsibility. These are not words that are often applied to software development.In this completely revised introduction to Extreme Programming (XP), Kent Beck describes how to improve your software development by integrating these highly desirable concepts into your daily development process.The first edition of Extreme Programming Explained is a classic. It won awards for its then-radical ideas for improving small-team development, such as having developers write automated tests for their own code and having the whole team plan weekly. Much has changed in five years. This completely rewritten second edition expands the scope of XP to teams of any size by suggesting a program of continuous improvement based on: Five core values consistent with excellence in software development Eleven principles for putting those values into action Thirteen primary and eleven corollary practices to help you push development past its current business and technical limitationsWhether you have a small team that is already closely aligned with your customers or a large team in a gigantic or multinational organization, you will find in these pages a wealth of ideas to challenge, inspire, and encourage you and your team members to substantially improve your software development.You will discover how to: Involve the whole team—XP style Increase technical collaboration through pair programming and continuous integration Reduce defects through developer testing Align business and technical decisions through weekly and quarterly planning Improve teamwork by setting up an informative, shared workspaceYou will also find many other concrete ideas for improvement, all based on a philosophy that emphasizes simultaneously increasing the humanity and effectiveness of software development.Every team can improve. Every team can begin improving today. Improvement is possible—beyond what we can currently imagine. Extreme Programming Explained, Second Edition, offers ideas to fuel your improvement for years to come. Booknews Beck, who owns and operates his own software company, wants to encourage readers to reexamine their preconceptions of how software development ought to occur. He does just that in this overview of Extreme Programming (XP), a controversial approach to software development which challenges the notion that the cost of changing a piece of software must rise dramatically over the course of time. This book covers the basics of XP, including the integration of testing throughout the whole system, beginning projects with a simple design, and expanding and changing it as you go along. XP asserts that programmers should participate at every phase of a project, rather than specialize, and it encourages face-to-face communication with two programmers at a screen. Annotation c.

The goal of Extreme Programming (XP) is outstanding software development. Software can be developed at lower cost, with fewer defects, with higher productivity, and with much higher return on investment. The same teams that are struggling today can achieve these results by careful attention to and refinement of how they work, by pushing ordinary development practices to the extreme.\ There are better ways and worse ways to develop software. Good teams are more alike than they are different. No matter how good or bad your team you can always improve. I intend this book as a resource for you as you try to improve.\ This book is my personal take on what it is that good software development teams have in common. I’ve taken things I’ve done that have worked well and things I’ve seen done that worked well and distilled them to what I think is their purest, most “extreme” form. What I’m most struck with in this process is the limitations of my own imagination in this effort. Practices that seemed impossibly extreme five years ago, when the first edition of this book was published, are now common. Five years from now the practices in this book will probably seem conservative.\ If I only talked about what good teams do I would be missing the point. There are legitimate differences between outstanding teams’ actions based on the context in which they work. Looking below the surface, where their activities become ripples in the river hinting at shapes below, there is an intellectual and intuitive substrate to software development excellence that I have also tried to distill and document.\ Critics of the first edition have complained that it tries to force them to program in a certain way. Aside from the absurdity of me being able to control anyone else’s behavior, I’m embarrassed to say that was my intention. Relinquishing the illusion of control of other people’s behavior and acknowledging each individual’s responsibility for his or her own choices, in this edition I have tried to rephrase my message in a positive, inclusive way. I present proven practices you can add to your bag of tricks.\ \ No matter the circumstance you can always improve.\ You can always start improving with yourself.\ You can always start improving today.\
