The McKinsey Horizons Model is a strategic framework that helps organizations prioritize and manage growth initiatives across different time frames. It divides growth opportunities into three horizons: Horizon 1 focuses on core businesses with established products, Horizon 2 explores emerging opportunities that can drive growth in the near term, and Horizon 3 emphasizes long-term, transformative innovations. This model encourages companies to balance investments across these horizons to ensure sustainable growth and adaptability in a changing market.
