OKRs and OGSM are both strategic planning tools used to set goals, but they differ in important ways. OKRs focus on setting quarterly objectives and key results that are measurable and help teams adapt quickly. In contrast, OGSM involve setting multi-year objectives, annual goals, and strategies to achieve those goals, with less frequent updating. A key difference is that OKRs emphasize frequent feedback to help teams course-correct, while OGSM does not have a set process for integrating employee input as strategies are implemented.
