A good business model is:

• Aligned with company goals - allows the company to achieve its goals
• Self-reinforcing - should create virtuous cycles within company’s business model (e.g. low cost -> low price -> high volume -> lower cost -> lower price) and create vicious cycles in competitors’ business models
• Robust - should be able to protect itself from copying the business model by competitors, other parties exercising bargaining power over the company, the complacency of the company, and other products decreasing value of company’s products
