As a strategist, you must understand and calibrate the environment in which your organization operates. How generous or challenging is the environment? What forces drive the munificence or sparseness of your environment? How are those forces changing, and what is their likely impact on your organization? Is this change slow or fast? Can you influence or mold those forces in ways that benefit your organization? This module note, Market Attractiveness, helps you address these questions. It offers a framework to understand the forces that influence the environment in which your enterprise operates, evaluate the attractiveness of the environment, plan how best to respond to these forces, and contemplate how your enterprise can shape the environment favorably.
