This chapter discusses new entry opportunities and strategies for exploiting them. It covers 3 key stages: 1) generating new entry opportunities, 2) exploiting entry opportunities, and 3) feedback between generation and exploitation. When generating opportunities, resources must be valuable, rare, and inimitable. Entrepreneurs assess opportunities by determining if the product/market are attractive enough based on prior knowledge and the window of opportunity. The decision to exploit an opportunity depends on having sufficient information and comfort with uncertainty given the window may close.
