Getting software released to users is often a painful, risky, and time-consuming process.
This groundbreaking new book sets out the principles and technical practices that enable
rapid, incremental delivery of high quality, valuable new functionality to users. Through
automation of the build, deployment, and testing process, and improved collaboration between
developers, testers, and operations, delivery teams can get changes released in a matter of hours—
sometimes even minutes–no matter what the size of a project or the complexity of its code base.
Jez Humble and David Farley begin by presenting the foundations of a rapid, reliable, low-risk
delivery process. Next, they introduce the “deployment pipeline,” an automated process for
managing all changes, from check-in to release. Finally, they discuss the “ecosystem” needed to
support continuous delivery, from infrastructure, data and configuration management to governance.
The authors introduce state-of-the-art techniques, including automated infrastructure management
and data migration, and the use of virtualization. For each, they review key issues, identify best
practices, and demonstrate how to mitigate risks. Coverage includes
• Automating all facets of building, integrating, testing, and deploying software
• Implementing deployment pipelines at team and organizational levels
• Improving collaboration between developers, testers, and operations
• Developing features incrementally on large and distributed teams
• Implementing an effective configuration management strategy
• Automating acceptance testing, from analysis to implementation
• Testing capacity and other non-functional requirements
• Implementing continuous deployment and zero-downtime releases
• Managing infrastructure, data, components and dependencies
• Navigating risk management, compliance, and auditing
Whether you’re a developer, systems administrator, tester, or manager, this book will help your
organization move from idea to release faster than ever—so you can deliver value to your business
rapidly and reliably.
Dave Farley has been having fun with computers for nearly 30 years. Over that period he has worked on most types of software, from firmware, through tinkering with operating systems and device drivers, to writing games, and commercial applications of all shapes and sizes. He started working in large scale distributed systems about 20 years ago, doing research into the development of loose-coupled, message-based systems - a forerunner of SOA. He has a wide range of experience leading the development of complex software in teams, both large and small, in the UK and USA. Dave was an early adopter of agile development techniques, employing iterative development, continuous integration and significant levels of automated testing on commercial projects from the early 1990s. He honed his approach to agile development in his four and a half year stint at ThoughtWorks where he was a technical principal working on some of their biggest and most challenging projects. Dave is currently working for the London Multi-Asset Exchange (LMAX), an organization that is building one of the highest performance financial exchanges in the world, where they rely upon all of the major techniques described in this book.
Jez Humble has been fascinated by computers and electronics since getting his first ZX Spectrum aged 11, and spent several years hacking on Acorn machines in 6502 and ARM assembler and BASIC until he was old enough to get a proper job. He got into IT in 2000, just in time for the dot com bust. Since then he has worked as a developer, system administrator, trainer, consultant, manager, and speaker. He has worked with a variety of platforms and technologies, consulting for non-profits, telecoms, financial services and on-line retail companies. Since 2004 he has worked for ThoughtWorks and ThoughtWorks Studios in Beijing, Bangalore, London and San Francisco. He holds a BA in Physics and Philosophy from Oxford University and an MMus in Ethnomusicology from the School of Oriental and African Studies, University of London. He is presently living in San Francisco with his wife and daughter.
This is the definitive, realistic, actionable guide to starting fast with Scrum and agile–and then succeeding over the long haul. Leading agile consultant and practitioner Mike Cohn presents detailed recommendations, powerful tips, and real-world case studies drawn from his unparalleled experience helping hundreds of software organizations make Scrum and agile work.
Succeeding with Agile is for pragmatic software professionals who want real answers to the most difficult challenges they face in implementing Scrum. Cohn covers every facet of the transition: getting started, helping individuals transition to new roles, structuring teams, scaling up, working with a distributed team, and finally, implementing effective metrics and continuous improvement.
Throughout, Cohn presents “Things to Try Now” sections based on his most successful advice. Complementary “Objection” sections reproduce typical conversations with those resisting change and offer practical guidance for addressing their concerns. Coverage includesPractical ways to get started immediately–and “get good” fast Overcoming individual resistance to the changes Scrum requires Staffing Scrum projects and building effective teams Establishing “improvement communities” of people who are passionate about driving change Choosing which agile technical practices to use or experiment with Leading self-organizing teams Making the most of Scrum sprints, planning, and quality techniques Scaling Scrum to distributed, multiteam projects Using Scrum on projects with complex sequential processes or challenging compliance and governance requirements Understanding Scrum’s impact on HR, facilities, and project management
Whether you've completed a few sprints or multiple agile projects and whatever your role–manager, developer, coach, ScrumMaster, product owner, analyst, team lead, or project lead–this book will help you succeed with your very next project. Then, it will help you go much further: It will help you transform your entire development organization.
In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world.

In The Clean Coder: A Code of Conduct for Professional Programmers, legendary software expert Robert C. Martin introduces the disciplines, techniques, tools, and practices of true software craftsmanship. This book is packed with practical advice–about everything from estimating and coding to refactoring and testing. It covers much more than technique: It is about attitude. Martin shows how to approach software development with honor, self-respect, and pride; work well and work clean; communicate and estimate faithfully; face difficult decisions with clarity and honesty; and understand that deep knowledge comes with a responsibility to act.
Readers will learnWhat it means to behave as a true software craftsman How to deal with conflict, tight schedules, and unreasonable managers How to get into the flow of coding, and get past writer’s block How to handle unrelenting pressure and avoid burnout How to combine enduring attitudes with new development paradigms How to manage your time, and avoid blind alleys, marshes, bogs, and swamps How to foster environments where programmers and teams can thrive When to say “No”–and how to say it When to say “Yes”–and what yes really means
Great software is something to marvel at: powerful, elegant, functional, a pleasure to work with as both a developer and as a user. Great software isn’t written by machines. It is written by professionals with an unshakable commitment to craftsmanship. The Clean Coder will help you become one of them–and earn the pride and fulfillment that they alone possess.
