The McKinsey 7S model breaks down an organization into 7 key factors that influence its ability to implement strategy: strategies, structure, systems, shared values, style, staff, and skills. These factors are interdependent and can be categorized as either "hard" elements like strategies, structure and systems that are easier to change, or "soft" elements like shared values, style, staff and skills that are more difficult to change directly and take longer. The model provides a framework for analyzing how well an organization's strategic elements align and identifies areas for improvement.
