The document discusses the McKinsey 7S model, which examines seven internal elements of an organization: structure, strategy, systems, skills, style, staff, and shared values. It provides definitions for each element and describes a four-step process for applying the model to identify inconsistencies within an organization and determine the optimal design for change. The advantages of aligning all elements are discussed, as well as some potential disadvantages in changing business environments. An example of applying the model during a company merger is also provided.
