Answer:
A) mutual goal setting between the sales manager and the salesperson.
Explanation:
Management by objectives (MBO) is a management approach that is based on setting attainable goals for every member of the organization. These goals must be set together and agreed by the employee and his/her supervisor.
One of the main advantages of this approach is that it creates a more productive environment where all of the members of the organization know their goals and work towards achieving them. This approach allows no excuses, since the responsibility of setting the goals is shared between the manager and the employee.
