What is an Assumption Grid?
The Assumption Grid, developed by IBM, is a powerful tool that helps you decide which assumptions from your business model you should test first. By visualizing your assumptions, the grid empowers you to make judgment calls, prioritize, mitigate risk, and overcome uncertainties. The grid plots your assumptions on two axes: high impact assumptions for which you have little information, and low impact assumptions for which you have little information.
After you've put different items on the grid, the Assumption Grid becomes a good way to communicate with others. Get your team together and have them discuss the results. You might end up with new assumptions, or you might change where some of the items are on the grid.
