The document discusses the Teece model and Clarysse's Entrepreneurial Strategy Matrix for assessing entrepreneurial strategies. The Teece model assesses the protectability of a business idea and the ease of accessing complementary assets needed to bring the idea to market. It evaluates whether independent market entry or a cooperative partnership strategy is better. Clarysse's matrix builds on this by also considering whether a market for products or technologies is more suitable and what resources will be required for different strategies. Examples are provided to illustrate applying the models. The models help determine a viable business strategy by assessing threats to an idea's protectability and access to needed complementary assets.
