A CTO's perspective
The quick answer is the business model(s) informs the business strategy.
A business model is a scientific concept model turning the key elements in any business into a graphic model. Key elements present in any business are the target market, how you reach your target market, what value you are providing them unique to what’s on the market already (what problem you are solving), how the business will bring in revenue, the key activities of the business required to deliver the value, and the expenses. Combined, these elements drive strategic decision-making in the business. The decisions are turned into planned actions with expected outcomes and deadlines as a strategy. Business level strategies would be more focused on the delivery of the key elements of unique value, increasing reach and expansion of target segments.
