This article explains how to design an experiment to help prove or reject your assumptions.


Before you can design your experiment, you need to have:

  • established the assumptions on which you have based your business model
  • categorised these assumptions against the four validation themes
  • assigned each assumption a level of priority

You now need to establish if these assumptions are valid. There is no one-size-fits-all experiment: your assumptions will be many and varied, and so experiments will also vary. In general, however, you should be aiming to gather as much information in the least time, and at the lowest cost possible.


We use experiment cards on Solverboard to help you collect all information relating to an experiment in one place, and link it to the assumption you are trying to prove. These cards encourage you to follow a simple four-step process:

  1. Define your method – What are you going to test and how? You should be testing something about which you are uncertain, so failure is to be expected.
  2. What outcome are you expecting? – We will ask you to pass or fail an experiment, so you need to have thought about what a pass looks like. What is your minimum expectation to prove the assumption?
  3. Learn, learn and learn – Whatever the outcome, every experiment provides another bit of knowledge that may be useful at some point in the future. Solverboard enables you to capture all the learnings, whether they are essential now or might be useful at some point in the future.
  4. Declare the result – Objectively state the result: pass, fail or inconclusive.
