When are progressive delivery patterns useful in software development and deployment?

Progressive delivery is a GitOps pattern used to release software gradually, reducing risks associated

with deploying new versions. Techniques such as canary releases, feature flags, and blue-green

deployments allow teams to incrementally roll out changes, validate functionality with subsets of

users, and minimize potential disruptions.

“Progressive delivery builds on continuous delivery by enabling safer, incremental rollouts. This

pattern reduces risk, improves reliability, enhances user experience, and allows for validation of

features with a portion of users before wider release.”

Therefore, progressive delivery is useful in multiple scenarios (not just one-time deployments or

small teams), making option C correct.
