Assumption Collecting

What is an Assumption Collecting workshop?

This tactic helps you uncover the assumptions you and your team may have about a project.

Declaring what you think to be true at the start of the project to help you identify risks. Having everyone’s assumptions visible early removes any surprises later on.

Try running Problem Statement beforehand to give you a clear problem to start unpacking your assumptions from. Afterwards, prioritise your riskiest assumptions with Assumption Map.
