Management by Objectives (MBO) is a process where managers and employees jointly set objectives, understand their roles, and monitor performance against goals. The goals should be specific, measurable, achievable, relevant and time-bound. Involving employees in setting goals increases motivation, communication, and commitment to meeting objectives. However, MBO works best when contexts like resources and leadership support are also considered, and objectives are discussed not just set, to avoid potential limitations like a focus only on short-term targets.
