Continuous Integration, Continuous Quality, Continuous Delivery
The document discusses continuous delivery practices including defining goals and features through examples and stories, automating acceptance criteria tests, and implementing application code to pass those tests. It emphasizes that quality must be built into the process through techniques like test automation to enable continuous delivery of value to the business. Automating acceptance criteria keeps projects on track, provides better visibility, allows faster release cycles, and reduces risk and costs.
