Usage Intensity

Usage intensity describes how deeply a user works with a product on each visit, as opposed to frequency, which only describes how often they come.

The concept has no single metric and is usually assembled from several: events per session, the number of distinct features touched and active time per session. Its value appears when it is placed next to frequency, because the two axes describe very different users: someone who drops in for thirty seconds daily and someone who works for an hour once a week can look identical in an active-user report. The main warning is not to read high intensity as automatically good, since many events in one session can mean either mastery or floundering, and separating the two is impossible without looking at task completion.
