What it does
Teams often push growth before they know whether anyone would miss the product. They spend on ads and launches, and users arrive, try it and leave. Without a clear read on who loves it, every growth idea looks equally good. This workflow asks the one question that tells you: how would you feel if you could no longer use it? If at least 40 percent of active users say very disappointed, you have something worth growing. It also studies the group who say that, so you know what they value and who they are. After you collect answers, it ranks growth ideas on impact, confidence and ease and plans a test for each of the top ones. The method comes from Sean Ellis's article "Key to Sustaining Rapid Growth" and his earlier writing on growth hacking.
