## Meaning

To introduce or launch something new on a larger scale.

Roll out describes the process of releasing something to production in stages rather than all at once. Engineers mention this during standups when discussing release timelines, in pull request discussions about deployment strategy, and during incident reviews when explaining how a problem spread. You'll also hear it in interviews when candidates describe their deployment experience. The staged approach is key to the concept. Instead of immediately exposing all users to a change, teams gradually increase the percentage. A engineer might say, "We're rolling out the new authentication system to five percent of traffic first, then bumping it to twenty-five percent after monitoring for errors." A common learner mistake is using roll out interchangeably with "release" or "launch." While related, roll out specifically emphasizes the gradual, controlled distribution method rather than a single binary moment. The term implies caution and measurability built into the deployment process.

## When you hear it

Used in standups, Slack, sprint planning, release notes, and stakeholder updates. Works in casual and formal settings.

## Examples

- **Standup:** "I'm working on the final tests before we roll out the payment feature tomorrow."
- **Slack message:** "Heads up: we're rolling out the new auth flow to 20% of users today."
- **GitHub PR:** "This PR adds the feature flag so we can roll out the change gradually."
- **Jira ticket:** "Roll out dark mode to all mobile users by end of Q2."
- **Retrospective:** "The rollout went smoothly because we tested with beta users first."
- **Sprint planning:** "We need two more sprints before we can roll out the redesign."
- **Pair programming:** "Let's add a toggle here so we can roll this out without affecting existing users."

## What native speakers say

- "We're planning to roll out the new dashboard next week."
- "Let's roll this out to 10% of users first and see how it goes."
- "The rollout is scheduled for Monday after the freeze ends."
- "We rolled out the fix yesterday and the error rate dropped."
- "Can we delay the rollout until after QA signs off?"

## Common mistakes

- ✗ "We will roll out the feature to production." → ✓ "We will roll out the feature to users." (You deploy to production (servers), but you roll out to users (people). Roll out focuses on who receives the change.)
- ✗ "I rolled out my code yesterday." → ✓ "I pushed/deployed my code yesterday." (Roll out is for features or products reaching users, not for individual code commits.)
- ✗ "We need to roll out this bug." → ✓ "We need to fix this bug." (Roll out means to release something new, not to solve a problem.)

## FAQ

### What is the difference between 'roll out' and 'deploy'?

Deploy focuses on putting code on servers. Roll out focuses on making features available to users. You deploy code, then roll out the feature to users.

### Can I say 'roll out' for a small internal tool?

Yes. You can roll out features to your team, to beta users, or to all users. The size doesn't matter—roll out works for any audience.

### Is 'rollout' one word or two?

As a verb, it's two words: 'roll out.' As a noun, it's one word: 'rollout.' Example: 'We will roll out the feature. The rollout is Monday.'

### What does 'phased rollout' mean?

A phased rollout means releasing in stages—first to 10% of users, then 50%, then 100%. This helps teams find bugs before everyone sees them.

### Can I use 'roll out' in a formal email to stakeholders?

Yes. Roll out is professional and clear. It works in standups, Slack, and formal updates. Example: 'We plan to roll out the new system in Q3.'

The opposite is 'roll back.' If you roll out a feature and find a problem, you roll back to the previous version.
