ETA

ETA — ETA stands for "estimated time of arrival".

In simple English

ETA comes from travel ("the flight's ETA is 6pm"), but in tech teams it is used for anything that will be done in the future: a fix, a feature, a report, or a person joining a call. "What's the ETA on the hotfix?" means "When do you think the hotfix will be ready?" An ETA is a guess, not a promise, so people often add "rough ETA" or update it later.

How to say it: Say the letters: "ee-tee-ay", stress on the last letter.

ETA full form: estimated time of arrival. Here is how to ask for and give an ETA at work.

Say it like this

  • What's the ETA on the fix?
  • Rough ETA is end of day tomorrow.
  • No ETA yet, I'll update you by 3pm.

Use it at work

Asking

  • What's the ETA on this?
  • Do we have a rough ETA?

Giving one

  • ETA is end of day tomorrow.
  • I'd say Thursday, but I'll confirm after testing.

Updating

  • Quick update: the ETA has moved to Monday.
  • No ETA yet, next update at 3pm.

Don't say this

✕When is the ETA of the fix?
✓What's the ETA on the fix? / When will the fix be ready?

ETA already means "when", so ask "What's the ETA?", not "When is the ETA?"

Handle with care. An ETA is a guess. If it changes, update people early instead of missing it quietly.

  • ✕The ETA is guaranteed for Friday.
    ✓Our ETA is Friday, but it may move if testing finds issues.

    An ETA is an estimate. Don't present it as a promise.

  • ✕ETA: soon.
    ✓ETA: Thursday afternoon.

    An ETA should be a time or date. "Soon" doesn't help anyone plan.
