Feature Usage

Feature usage is the measurement of how much and by whom each part or capability of a product is used, to reveal each feature's real value.

Feature usage is not a single metric but a family of questions: how many discovered a feature, how many adopted it into a habit, and what share abandoned it. Its importance is that it saves a product team from guessing; a feature built with great effort but little used must either be introduced better or dropped. The big trap is relying on raw counts: 10,000 uses without a denominator is meaningless, because it is unclear out of how many exposed users. So feature usage should be turned into a rate (what share of users who could have used it actually did) to make large and small features comparable. This is the umbrella under which breadth of use, depth of use, feature stickiness and feature adoption rate all sit.
