Why do you use it?

After the energy and excitement of a creative ideation process, it's common for innovators to fall in love with their solution idea - and to fail to recognise its potential flaws. This canvas guides you through a structured process to question your assumptions about whether your idea is really as desirable, feasible, and viable as you think.

When do you use it:

This canvas is designed to be used after a creative ideation process, once you've selected an idea or a number of ideas about how best to solve the problem at hand. It enables you to identify some of the unproven assumptions that you might need to test in the prototyping process.

How to use it:

With a particular solution idea in mind, move around the canvas and answer each of the questions in turn.

• Desirability: Start by listing any evidence you already have that your solution is something people want and will actually use. Then, try to identify any untested assumption you have about your idea's desirability.
• Feasibility: First, explore the evidence already at hand that your idea is technically feasible and that you have the skills and technology needed to bring it to life. Next, ask yourself what assumptions you might be making about the feasibility of your idea.
• Viability: Begin by listing what's already been proven about whether your idea makes business sense and could be sustainable. Then identify any untested assumptions about the viability of your solution idea.
