a canvas helps to structure ideas and directions.
the canvas is just a snapshot of a product, and there are a number of different canvasses out there. for example, the pain/gains/job canvas, which I tried to apply to freelance projects: <a href="http://thinkingonthinking.com/customers-jobs/" rel="nofollow">http://thinkingonthinking.com/customers-jobs/</a> - what could be wrong with this?
