OKR stands for Objectives and Key Results, which is a goal-setting framework used by individuals, teams, and organizations to define measurable goals and track their outcomes. The development of OKR is generally attributed to Andrew Grove who introduced the approach to Intel in the 1970s.

The OKR framework comprises an objective, which is a significant, concrete, and clearly defined goal, and 3-5 key results, which are measurable success criteria used to track the achievement of that goal. The key results are quantifiable and actionable, and they help track progress, create alignment, and encourage engagement around measurable goals.

OKRs are designed to provide a framework for groups, not individuals, and the process is designed to ensure that all areas of the business are working together toward the same objectives. OKRs are flexible and can be used to set goals at different levels, from company-wide objectives to individual goals.

OKRs have become popular in the tech industry, with companies such as Google, LinkedIn, Twitter, Uber, Microsoft, and GitLab using them. The OKR framework fosters an agile and adaptable approach, enabling organizations to cascade goals from top-level to individual objectives. Regular check-ins and transparency ensure accountability and continuous improvement.

In summary, OKR is a goal-setting framework that helps individuals, teams, and organizations define measurable goals and track their outcomes. It comprises an objective and 3-5 key results, and it is designed to provide a framework for groups to work together towards the same objectives.
