This document provides an overview of Objectives and Key Results (OKRs), including: 1) OKRs are a goal-setting framework that cascades organizational objectives down through departments and individual goals, with quantifiable key results to measure success. 2) The framework originated at Google in 1999 and has since spread to other tech companies to drive performance through data-driven goals. 3) OKRs follow a process where objectives and key results are negotiated between managers and direct reports, with 60-70% achievement targeted each quarter through continuous feedback and learning.
