I don’t hold most startup accelerators in high regard, but the one very stimulating activity we did was based on the ‘business model canvas’. It’s a marginally useful thing in itself to document all the moving parts of your business (real or imagined) but I really enjoyed a session we spent just working on hypotheticals like in this article, like what if this key resource is no longer available? What if you need new channels? You immediately realise that your business is a vector in a high-dimensional space and you can explore in any direction you like looking for some sort of fit. It was a great way of shaking us out of linear thinking, and instilling a sense of agility all the way down in a company.
