The development of OKRs is generally attributed to Andy Grove, the “Father of OKRs”, who introduced the approach to Intel during his tenure there and documented this in his 1983 book High Output Management. Grove’s simple but effective concept is explained by John Doerr: “The key result has to be measurable. But at the end you can look, and without any arguments: Did I do that or did I not do it? Yes? No? Simple. No judgments in it”.
Objectives and key results (OKR) is a goal-setting framework for defining and tracking objectives and their outcomes.
