As you think through your idea and start to test it, you’ll also need to remain cognizant of your business model. A good way to keep it front and center in your mind is by using a Business Model Canvas. This simple sheet asks you key questions like what’s your revenue stream, what are key partnerships you’ll need to forge, and what resources are vital to your operation. You might even use a Business Model Canvas several times in the process as elements are bound to change as you refine your idea and move toward implementing it.
