A metric is named: needs work
Name the thing you will measure, for example "30-day repeat purchase rate" or "support tickets per week".
It says how much or which direction: needs work
Add a number or a direction to the metric, for example "from 18% to 24%" or "reduce by a third".
It is time-boxed: needs work
Give a duration with a unit, for example "6 weeks" or "2 sprints", so you know when to check.
The expected result is an outcome, not an output: needs work
Describe what changes for people or the business (for example "fewer abandoned carts"), not what you deliver ("launch a new checkout").
