Corporate strategy involves determining what business(es) a company is or wants to be in and how to maximize performance across businesses. It establishes the overall direction for a company. A company's corporate strategy is constrained by where it sits on a continuum from very general to highly specialized resources. Most companies mistakenly enter businesses based on similarity in products rather than underlying resources. An effective corporate strategy ensures a tight fit among the company's resources, objectives, and competitive strategies. While any one strategy may work well for some companies, every company's context is different, so the strategy must suit its unique resources. The test of a good corporate strategy is whether the business is worth more to the current owners than potential new owners.
