Find Missing Requirements
This blog post by Betsy Stockdale explains how to use the Feature Tree model to discover missing requirements.

There are three possible levels of features that might be useful for organizing the requirements: Level 1 (L1), Level 2 (L2), and Level 3 (L3). Below L3 are individual requirements themselves.
