The document provides a guide to Objectives and Key Results (OKRs), a goal-setting methodology popularized by companies like Google and LinkedIn since its introduction by John Doerr in 1999. OKRs involve setting measurable objectives with 3-5 key results and are designed to improve team focus and communication while being visible to all team members. The methodology encourages regular check-ins and can be implemented at any organizational level to align and track goals across the company.
