A Minimum Viable Feature (MVF) can be defined as a function of a product that has the smallest number of attributes but remains operable. This is similar to, but not the same as a Minimum Feature Product (MVP).
The feature is experimental, easy, and efficient to roll out, and enables the collection of data for analysis. Typically, an MVF creates the opportunity for collecting user feedback information or data concerning operational feasibility. This data can be used in turn to add attributes to the feature, enhance the overall product, or indeed, discard the feature completely.
