“An OBJECTIVE, I explained, is simply WHAT is to be achieved, no more and no less. By definition, objectives are significant, concrete, action oriented, and (ideally) inspirational. When properly designed and deployed, they’re a vaccine against fuzzy thinking—and fuzzy execution. KEY RESULTS benchmark and monitor HOW we get to the objective. Effective KRs are specific and time-bound, aggressive yet realistic. Most of all, they are measurable and verifiable. (As prize pupil Marissa Mayer would say, “It’s not a key result unless it has a number.”) You either meet a key result’s requirements or you don’t; there is no gray area, no room for doubt.”
