Management by Objectives (MBO) is a process where long-term goals are set collaboratively for the business and then cascaded down to each division. These goals typically range from 12 months to 3 years. MBO is used to define performance standards for non-routine tasks like management or projects. The manager and employee agree on goals and how they will be measured, meeting regularly to discuss progress. Goals can be revised based on new inputs. At the end of the period, the manager reviews performance against goals. MBO also assesses how goals were achieved, like following processes and engaging stakeholders appropriately. MBO is often used with other appraisal systems to fully evaluate job performance.
