Rolling out a product or improvement involves deploying and launching new features or updates to an existing user base.
A comprehensive rollout plan should address testing protocols, progressive deployment plan, rollback process, communication plan, and user documentation.
Progressive deployment strategies include canary deployments, blue/green deployments, rolling deployments, and shadow deployments.
Feature flags, or feature toggles, provide flexibility in the deployment process by enabling specific features for a subset of users before rolling out to the entire user base.
