The horizon model is a framework that helps organizations balance their investments across different time horizons and types of innovation. According to the Scaled Agile Framework, there are four horizons: Horizon
0, Horizon 1, Horizon 2, and Horizon 31. Horizon 1 describes the desired state as stable solutions that deliver high value with minimal new investment. These are the core products or services that generate most of the current revenue and profit, and have a loyal customer base. Horizon 1 solutions require continuous improvement and optimization, but not significant new investment or disruption. Horizon 1 can be further divided into two sub-horizons: Investing and Extracting2.
