The assumption grid is for helping you decide what assumptions on your business model to test first.

Here's a quick explanation on the grid and how to use it:

Using the grid to decide what to test first

The grid plots your assumptions on two axes: How much you know about it, and how much impact it has on your business if it turns out false. The high-impact assumptions you know little about are the ones you should focus on first:

However, the assumptions that are low impact but you know little about are also important, as you might find out they're higher impact than you'd thought as you start testing them!

The assumptions that are high impact and you're certain of are the ones to plan for, and the assumptions you're certain of are low impact can be safely ignored.

See what areas of the Business Model Canvas you're covering

When you start adding assumptions you'll notice they have different colours. This is to visually indicate what areas of the BMC (Business Model Canvas) it's covering. You can find the legend underneath the grid:

Filtering on assumptions

You might have noticed this little section above the grid:

This is for filtering on assumptions on the grid. You can select the different options to show either open, validated, or invalidated assumptions, or show them all at once!
