Progressive Delivery is a strategic approach to software deployment that emphasizes learning from failures and minimizing their impact by delivering changes incrementally to small, low-risk audiences before gradually expanding to larger groups. This method allows for real-time validation and feedback, enabling companies like Target and IBM to manage feature releases more effectively. Key components include release progression, which involves carefully selecting the audience to limit risks, and delegation, which empowers relevant teams to manage features and respond swiftly to issues. Utilizing techniques such as A/B testing, chaos engineering, and canary testing, Progressive Delivery ensures a controlled and adaptable rollout process. Essential tools like feature flags and observability help identify and recover from failures, allowing for targeted action such as load shedding or request throttling. By fostering a culture that anticipates and learns from failures, Progressive Delivery equips organizations to deploy software safely and efficiently.
