Your business model determines the strategy you should be pursuing. It defines the issues your business confronts. It prioritizes the problems you must address. Models are more important than "industry," "environment," or "resources."
To take command of your strategy, you must understand your current model and its requirements. There are four model types. Each has unique requirements. What works for one model won't necessarily work for another.
To master your strategy, you must take command of the mix of models within your company. No model is perfect. Each has its own inherent strengths and weaknesses. By blending the right models into your enterprise, you can create a whole that's stronger than the sum of the parts.
