METRICS in Agile can have three most important goals:

• To measure how much value is being delivered to customers.
• To measure effectiveness delivery to the business.
• To measure a team’s health

Measuring deliverables:

• Team Velocity SHOWS how many user stories were completed by the team, on an AVERAGE, in previous sprints. It assists in estimating how much work the team is able to accomplish in future sprints.
• Escaped Defects shows how many bugs were experienced by users in production.
• Sprint burn-down shows the number of hours remaining to COMPLETE the stories planned for the current sprint, for each day during the sprint. 

Measuring effectiveness:

• Time to market shows the time a project takes to start providing value to customers.
• ROI shows the total revenue generated from a product vs. the cost of the sprints required to develop it.

Team’s health:

• Member turnover shows how healthy the team environment is.
• Team satisfaction survey shows how satisfied team members are with their work.
• Sprint retrospective gives a qualitative measurement of the team’s health.
