business-models

(Uit http://sethgodin.typepad.com/seths_blog/2009/05/thinking-about-business-models.html)
A business model is the architecture of a business or project. It has four elements:

1. [waarde propositie] What compelling reason exists for people to give you money? (or votes or donations)
2. [verdienmodel] How do you acquire what you're selling for less than it costs to sell it?
3. [entry barriers] What structural insulation do you have from relentless commoditization and a price war?
4. [marketing en communicatie] How will strangers find out about the business and decide to become customers?
