A feature rollout plan allows the introduction of a set of new features to a group of your user base, often to a limited user set initially.
A good rollout plan gives developers control of the releases in the development cycle of a limited set of features. This way is possible to ship and test specific changes into a control group before deploying to all your users.
In the early stages of development, a small team could release multiple changes to production every week or two. Testing the impact of specific changes was difficult because of the noise generated by releasing a large number of features at the same time. Another problem development teams faced with the early approach, was the risk of a full rollback if anything went wrong, which eats up the company's time and resources.
In response to this issue, many product teams started planning and releasing specific changes to a set of users instead of full feature releases. This approach allows for safer testing of the new feature.
A good feature rollout plan can provide a solution. One of the advantages is that it encourages collaboration and considered planning. Instead of pushing new features to all users, development teams are able to do controlled releases in the development cycle by incorporating a release strategy.
Sometimes a product with a large number of users will need major changes. In this situation, a rollout plan makes a significant impact on the success of those changes. Rolling them out in phases or segmenting users into groups to test different features gives companies the freedom to fully test the user interface and user experience, as well as to run more tests. This creates a faster feedback loop, which allows dev teams to spend less time debugging and more time building features.
There are multiple ways to deploy new feature rollouts; one useful method involves feature flags. Feature flags are a software development technique that let dev teams turn features on and off, without having to deploy new code. Using feature flags gives companies the ability to perform more incremental rollouts. It also fixes bugs in the code without redeploying, creating a smoother, more streamlined development cycle.
To properly execute a feature rollout plan, you'll need to implement careful planning, scheduling, controlling, and testing a feature every step of the way until its release. The process goes like this:
