The McKinsey 7S framework analyzes seven internal elements of an organization that must be aligned for it to be successful: strategy, structure, systems, shared values, style, staff, and skills. It was developed in the 1980s to improve company performance and examine the effects of changes. The model asserts that all elements are interconnected, so a change in one requires changes in the others. It can be used to align departments, implement strategies, and determine the best path forward for an organization.
