Top Feature
Beginner PronunciationEN/tɑːp ˈfiːtʃər/
A top feature is the part of a product with the highest usage in a period, measured either by number of uses or by number of distinct users.
The ranking flips entirely with the chosen denominator: counting events promotes features one user repeats ten times a day, while counting distinct users promotes features everyone touches once. The main trap is confusing mandatory steps with valuable capabilities, since the login screen and the home page always top the list although nobody chose the product for them. A more meaningful reading is repeat usage among the users who discovered the feature at least once, rather than the raw rank.
FAQ
Report both, because they answer different questions. User count describes breadth and usage count describes depth: few users with heavy usage usually means a power-user tool, while many users with light usage is often a mandatory step in a flow.
