Which horizon represents core businesses that provide the greatest profits and cash flow?

In the context of the SAFe framework and strategic planning, Horizon 1 is the correct choice for representing core businesses that provide the greatest profits and cash flow. This horizon typically encompasses established offerings that have been developed and refined over time, generating stable and substantial revenue for the organization.

Horizon 1 focuses on optimizing current business operations and sustaining existing products and services, making it crucial for maintaining profitability. Leaders invest in improving these core areas while ensuring customer satisfaction, as they form the backbone of the organization's financial success.

In contrast, other horizons represent different stages of innovation and potential growth. Horizon 0 concerns the current operations and focuses on immediate performance, while Horizon 2 and Horizon 3 address emerging opportunities and long-term investments. These latter horizons deal with exploring new markets and innovative products, which may not initially yield the same cash flow or profits as the established offerings in Horizon 1.
