Guide on Continuous Verifiable Delivery
Definition: Continuous Verifiable Delivery (CVD) is a principle in Agile that emphasizes the frequent and consistent delivery of useful and functioning features to customers. It's heavily linked with Continuous Integration and Continuous Deployment, as these practices facilitate the ability to continually deliver verified software.
Importance: CVD enhances transparency and trust with stakeholders by ensuring a demonstration of steady progress. It enables teams to provide value to their customers continuously, reduce risks, and improve product quality and customer satisfaction.
How It Works: Development teams create and test software in small, manageable chunks and integrate their changes into the main codebase frequently, ideally, several times a day. After successfully passing automated tests, these changes can be deployed to a production environment and made available to users.
Exam Tips: When answering questions about CVD, focus on its advantages such as improved quality, customer satisfaction, and reduced risk. Understand the difference between CVD and traditional release practices. The emphasis on CVD is on smaller, more frequent updates that are tested and integrated continually, allowing for quick feedback and adjustments. In traditional practices, large updates are made less frequently, usually entailing more risks.
Example Exam Question: 'What's the key benefit of Continuous Verifiable Delivery in Agile?' The answer should emphasize frequent value delivery, proactive risk reduction, and increased stakeholder trust.
