The DevOps Handbook: How to Create World-Class Agility, Reliability, & Security in Technology Organizations is a manual for technology companies looking to improve their ability to deliver high-value products to consumers.

In the 1980s, Toyota revolutionized manufacturing with its application of the lean production philosophy. Today, DevOps seeks to apply the principles of lean manufacturing to the technology industry. To do so, DevOps unites the two traditionally clashing bodies of the corporate IT department: development and operations. In traditional IT departments, the development group builds products and then hands them off to operations to launch them and keep them up and running. This can lead to tension because products may be untested in real-world conditions when development builds them, which leaves operations to clean up the mess while trying simultaneously to keep the product afloat for customers after launch.
