OKR stands for Objectives and Key Results. The form of the OKR has been more or less standardized. The Objective is qualitative, and the KR’s (most often three) are quantitative. They are used to focus a group or individual around a bold goal. The objective sets a goal for a set period of time, usually a quarter. The key results tell you if the objective has been met by the end of the time.
