Arrive at the right conclusions with assumption mapping

Figure out what you, your teammates, and your future customers might assume about a new product or service, then assess and address those issues for a successful launch or update.

Make assumptions with gumption

Think critically about emerging plans by exploring assumptions and categorizing them according to matrices of known vs. unknown and important vs. unimportant.

Identify issues: Discover the greatest threats, risks, and assumptions so you can iron them out during the initial stage.

Rate risks and rewards: Examine your level of certainty around each idea to create an organized system.

Manage your money: Save time and cash by validating potential assumptions before you dive into development.

Accessible assumption mapping for anyone

The more assumptions you can generate in initial planning, the clearer your path forward will be. Boost your numbers by inviting everyone in your network to a FigJam jam sesh. Share infinite ideas, rearrange them with ease, and offer feedback via chat, sticky, or stamp.


Assumption mapping involves identifying and exploring beliefs about an upcoming project. By using an assumption map—a 2x2 grid with known vs. unknown along one axis and important vs. unimportant on the other—you can outline any hypotheses you might have about a new product or service and categorize them accordingly.

These assumptions can be positive or negative. Either way, they’ll give you a clearer picture of everyone’s perception of the project.

First, assumption mapping allows you to gauge your team’s thoughts around a new project.

Second, the process can save you money by showing you which areas need to be assigned the most time and resources and which aren’t worth your efforts.

Finally, assumption mapping provides a literal map of where to go next. Transitioning from a finished assumption map to an actionable plan is effortless.

To lead an assumption mapping workshop, start with an assumption mapping example from FigJam. With an intuitive shareable graphic at your fingertips, you can invite everyone to join—whether they’re in the office or out of the country.

From there, you’ll gather all of your collaborators into your virtual room. Ask everyone in the room to list some assumptions someone could have about the project. Put yourself in the shoes of relevant stakeholders, such as existing customers or potential leads. Generally, these assumptions should relate to the desirability, feasibility, or viability of the project.

When you have your assumptions ready, you’ll arrange them on a grid by their importance and your certainty around them. This completed grid should point you in the right direction for future roadmaps and user testing.
