Metrics | Glossary

Definition

A wide range of metrics are available to Agile Project Managers to choose from and display various types of progress/ evaluation at both the iteration and release levels. The deeper the Managers understand metrics, the more effectively they will be able to communicate the progress to Project Stakeholders.

Metrics are used in daily meetings, iteration delta tables, release and burn-down charts, progress reports, value management and in running tested features. With metrics, one can also track the iteration back to release.
