Management by objectives (MBO), also known as management by results (MBR), was first popularized by Peter Drucker in his 1954 book The Practice of Management. Management by objectives is the process of defining specific objectives within an organization that can convey to organization members, then deciding on how to achieve each objective in sequence. This process allows managers to take work that needs to be done one step at a time to allow for a calm, yet productive work environment. This process also helps organization members to see their accomplishments as they achieve each objective, which reinforces a positive work environment and a sense of achievement. An important part of MBO is the measurement and comparison of an employee's actual performance with the standards set. Ideally, when employees themselves have been involved with the goal-setting and choosing the course of action to be followed by them, they are more likely to fulfill their responsibilities.
According to George S. Odiorne, the system of management by objectives can be described as a process whereby the superior and subordinate jointly identify common goals, define each individual's major areas of responsibility in terms of the results expected of him or her, and use these measures as guides for operating the unit and assessing the contribution of each of its members.
Peter Drucker first used the term "management by objectives" in his 1954 book The Practice of Management. While the basic ideas of MBO were not original to Drucker, they pulled from other management practices to create a complete “system”. The idea draws on the many ideas presented in Mary Parker Follett's 1926 essay, "The Giving of Orders".
After the term and idea were brought up, Drucker's student, George Odiorne, continued to develop the idea in his book Management Decisions by Objectives, published in the mid-1960s. MBO was popularized by companies like Hewlett-Packard, who claimed it led to their success.
Management by Objective at its core is the process of employers/supervisors attempting to manage their subordinates by introducing a set of specific goals that both the employee and the company strive to achieve in the near future, and working to meet those goals accordingly.
The principle of MBO is for employees to have a clear understanding of their roles and the responsibilities expected of them, so they can understand how their activities relate to the achievement of the organization's goals. MBO also places importance on fulfilling the personal goals of each employee.
