Why We Run Tiny, Fast Experiments


The FLEX framework has three goals:

  1. To help you focus
  2. To help you move fast
  3. To help you learn from your customers.

The FLEX Planner helps you with all three.

How to use Fluent’s  FLEX Planner


Use the FLEX Planner to design a Lean Experiment:

  1. Identify what stage of development to focus on – your Fluency Score recommendations point to the Expected Focus area
  2. Isolate the riskiest assumption in your business model for that stage. 
  3. Develop a tiny, fast experiment to test that assumption in the market with customers.
