My interpretation is that the business model is used for at least having some idea of how you will reach your customers and earn money. It may not work, so you may need to pivot or change your strategy, but you could have multiple channels for the same idea that you validated. I found this link off Steve Blank's site - http://www.businessmodelgeneration.com/canvas http://www.businessmodelgeneration.com/canvas That's the canvas in his book and you can use that to generate some ideas. It's not the formal paper model. You and your partner could be thinking of a "business plan" in two different ways. A formal business plan is much too stuffy, but you want at least some list of ideas on paper. That way when you get stuck and you're stressed out, you can go back and re-visit something you made when cooler heads prevailed.
