The 7-S Framework of McKinsey is a management model that analyzes seven internal elements of an organization: shared values, strategy, structure, systems, staff, style, and skills. The model was developed in the 1970s and aims to help companies understand their strengths and weaknesses, align with strategies, and optimize organizational design. It evaluates how an organization's culture, goals, plans, roles, processes, people, behaviors, and capabilities work together holistically.
