Software delivery models have evolved significantly over time, adapting to changing infrastructure, business needs, and development constraints. The evolution has been marked by the transition from waterfall methodology to agile and then to Continuous Delivery. One notable development methodology that has made its mark in recent years is Progressive Delivery. This approach enables controlled, incremental software delivery by allowing teams to control who sees what and when. It offers benefits for both developers and businesses, including speed and safety, more control over feature exposure, and faster innovation. Companies like Microsoft, IBM, JetBrains, Mozilla, and Google have successfully implemented Progressive Delivery principles in their operations, and it remains a promising approach in the software delivery ecosystem.
