I recommend you start with assessing “How much do we know about this assumption?” In other words, what evidence do we already have that tells us this assumption is true or false? If we have a lot of evidence that it’s true, then we would place the assumption on the left side of the x-axis. If we have very little evidence, we would place it on the right side of the x-axis. Next, we want to assess how important this assumption is to the success of your idea. Now, all assumptions are important to the success of your idea as currently designed. However, some assumptions can be easily worked around if they turn out not to be true. Others may be much harder to work around. These would make these assumptions more important. The more important an assumption is, the higher on the y-axis it gets placed. The less important it is, the lower on the y-axis it gets placed. Each
