Resumen: How are leaders to assess whether or not the purpose of the business is truly common and deeply shared? To be able to answer such questions, it is crucial we have a perspective that allows for the gathering of our employees¿ thoughts and feelings, a system that assesses the organization¿s health and its areas for improvement upon which to base our actions. This work develops the Purpose Strength Model, which establishes the basis for the development of measuring tools. The model integrates the different frameworks introduced in the previous chapters into four sequential areas: organizational purpose antecedents, purpose accelerators, shared purpose development, and purpose outcomes (individual and organizational). Theoretical implications and further research lines are discussed.
