Strategy as Action presents an action plan for how firms can build, improve, and defend their competitive advantage at every stage of their life cycle. For start-up firms entering a market, it provides a model for exploiting competitive uncertainty and blind spots; for growth firms who have established some market advantages, it provides an action plan for exploiting relative resources; for mature firms, it explains how to exploit market position; finally, for firms that have no decisive resource advantage, it provides an action plan based on firm co-operative reactions.
