Management by Objectives (MBO) is the traditional goal-setting system in which managers and employees define annual goals whose achievement is evaluated at year-end and often linked to a bonus. MBO works with SMART goals and remains standard in many organizations. It represents the historical precursor from which OKRs evolved.
The central differences from OKRs lie in cycle, direction, and incentive coupling. MBO is annual, OKR quarterly. MBO is top-down, OKR bidirectional. MBO is tied to compensation, OKR deliberately is not. A typical MBO goal reads: 15 percent revenue increase for the annual bonus. This works as a control mechanism but fosters neither transparency nor collaboration, because each employee primarily optimizes for their own targets. The annual cadence also prevents rapid adjustments to changing market conditions.
MBO traces back to Peter Drucker and his 1954 book The Practice of Management. Andy Grove built on it at Intel to develop the OKR methodology by introducing shorter cycles, measurable Key Results, and the decoupling of goals from compensation.
