Good OKRs help organizations align and stay that way by connecting company-level, team, and personal objectives to measurable results. This popular method for setting goals is defined by two characteristics: structure, and philosophy.
Structure: OKRs are built around two different questions.
1) Objective: Where do I want to go?
2) Key Result: How will I get there?
The Objective is the goal of the entire organization, team, or individual and the Key Results help you measure what matters in order to accomplish the objective (i.e., the "to do list"). This goal-setting framework is repeated from the top-down: from company objectives down to the goals of individual team members, which creates a cascading interplay of business goals that boosts employee engagement and keeps everyone aligned company-wide.
Philosophy: OKRs have a unique belief system around set goals that distinguishes itself from other goal setting methodologies.
This unique approach to goal setting was developed by Andy Grove at Intel and passed down to John Doerr who brought the company strategy to Google. Today, thousands of organizations from Spotify to the United States Navy use OKRs as one of their main management tools.
