Well, not everything is contained here but there’s a place for everything. In other words this model gives you a way to understand what you need to know right now and what you don’t need to learn till some other time.
Think about when you go to the doctor. The docs compare all your symptoms and test results to a model the’ve been trained in. That model gives them an understanding of how the body works and how to treat different situations. It’s interesting that different kinds of doctors are different because they have different kinds of models – a chiropractor has a different model than a more typical western doctor, and that’s different from the model of a accupucturist. But I digress.
This is the model I use when I look at a business.
