A Metric (KPI) is a quantifiable measure that is used to track and assess the status of a specific process. In other words, a Metric is a measurable/countable action -- an Email Sent, a Lead Converted, a Deal Won, etc.
Metric Definitions are the key to connecting your integrated business data to your individual Users. Metrics establish the connection between data and people, creating numerical metric values.
It's important to note that all data in Ambition must be attributable to a user. If your data exists at a Team or Organizational level, you must break that down into User level Metrics.
