As Miro, Mural, and other similar products become more and more popular, it becomes easier and easier to copy existing templates. But if you don't know much about the thing you are copying, it might not end up well.
For example, I've stumbled upon a template on assumption mapping and experiment design that has a critical flaw, essentially rendering nearly all findings useless. This template outlines four steps:
- Brainstorming Assumptions
- Prioritizing Assumptions
- Crafting Experiments
- Crafting Hypotheses
Can you spot the erroneous thinking?
Hypotheses come before the experiments, not after. That is Experimentation 101.
Experiments are used to test hypotheses. If you determine how will you test before what will you test, then you have confounded your experiment design, and won't be able to trust your findings.
The proper order is:
- Start by defining your learning goal.
- Surface the assumptions.
- Prioritise them if you wish.
- Translate prioritised assumptions into hypotheses (one assumption can have multiple hypotheses attached to it).
- Figure out which experiments do you want to do in order to test them.
I've written a detailed guide on how to design Lean Experiments that will create trustworthy and reusable knowledge:
