Business Models and Customer Development
The best definition of a startup I have heard is this:
A startup is a human institution designed to deliver new products and services under conditions of extreme uncertainty.
With the above definition, many groups other than what you might think of with the word startup could qualify. Its not just Google or Skype. It could be a new business unit within an existing company or even a department deliverying new products. It has a lot more to do with how the team operates and thinks about how to solve the problem - remember its a human institution - nothing to do with company size, sector or industry.
With that - take a look at this slide deck which merges ideas from two of my most favorite books - Business Model Generation
