Progressive Delivery: Is it the future of software delivery?

Progressive delivery is an approach to software delivery that involves shipping features in a disabled state, allowing for gradual activation when desired. This technique aims to speed up code deployment by reducing reliance on heavy QA processes and using feature flags to enable or disable features as needed. It differs from canary releases in its finer granularity and ability to target specific users or groups. Progressive delivery is useful for A/B testing, but the audiences for these tests are different: engineers focus on software stability and scalability, while product managers concentrate on user engagement and feature effectiveness. Feature flag toggles have become increasingly popular in recent years due to their power and versatility in managing feature activation.
