In PM, metrics are measures of things. Defining, selecting, applying, or calculating measurements of progress or activity on a project.

Metrics questions are generally about:

  1. What things to measure.
  2. How to measure those things.

Some common uses of the metrics tag would include questions about:

  1. Key performance indicators (KPIs).
  2. Velocity and burn-down charts.
  3. Throughput or cycle-time analyses.
  4. Completion or activity estimates, e.g. "This task is 83% done."
