You will learn: the five numbers that show if your delivery is getting better.

Checked with GitHub Actions 2026-10 on 31 Oct 2026

The problem

Your boss asks, “Is our delivery getting better?” You say, “It feels faster.” What would prove it?

Watch

Tap each point on the timeline.

A research group called DORA found five numbers that matter. Tap each one. They are the DORA metrics: Five numbers from the DORA research group that show how well a team delivers software..

Try it

DORA puts the five numbers in two groups. Sort them.

Drag a card into a box. Or tap the card, then tap the box.

      Predict

      Your team made 20 deploys this month. 2 of them needed an urgent fix. What is the change fail rate?

      Try it

      Good use of the numbers, or needs work? Swipe each one.

      Swipe right for good, left for needs work. Or use the buttons.

      1 / 4

      Compare your team with itself, month by month

      Check

      A deploy breaks the shop at 2:00 pm. It is fixed by 2:40 pm. Which number is 40 minutes?

      You did it!

      You can now name DORA’s five metrics and use them well.

      Go deeper (optional)

      DORA began with four metrics in 2014. In 2023, the old “time to recover” became failed deployment recovery time. In 2024, DORA added deployment rework rate. Measure one app at a time. Watch the trend, not one bad day.

      Real rep (optional): count your repo’s deploys last month. That is your deployment frequency.
