Where to start? How to start?
How often does it happen that we have ideas and we take actions to make these ideas happen, but we miss the big picture. I believe having a simple and powerful framework to "structure your thoughts" is essentail for a start up.
I find this 15-mins long video by IDEO's Tom Hulme very helpful in creating a easy to remember, easy to pitch and talk about, yet powerful framework around structuring business ideas and visualizing them.
