What Is Assumption testing?

Identify beliefs that a decision or plan depends on and seek evidence that could confirm, weaken, or disprove them.

Why Does Assumption testing Matter?

Assumption testing matters because plans often fail at the point where an untested belief was treated as a fact.

What Does It Look Like?

Someone applying assumption testing may:

  • writes down assumptions before committing to a plan
  • ranks assumptions by how much damage a wrong assumption could cause
  • looks for evidence that could falsify an attractive idea
  • changes the plan when a critical assumption proves weak

How to Develop Assumption testing

You can develop it by:

  • before starting a project, list five assumptions and the evidence needed to test each
  • choose the riskiest assumption and design the smallest useful test
  • review a failed decision and identify the assumption that was never verified
