First, jobs should be designed whenever possible to encourage employees to use a variety of skills. Think about why assembly line jobs tend to be boring. Standing in one place using only one or two skills doing the same thing over and over is not motivating for most people. Second, jobs should be designed whenever possible so that an employee performs a total job, e.g., all aspects of calf raising as contrasted with just feeding. Fourth, jobs should be designed so that each employee has responsibility, challenge, freedom and the opportunity to be creative.
Delegation can be a powerful motivator.
You can do the job however you want as long as you get results. Finally, supervisors should incorporate feedback into each job. Most employees want to know what is expected of them in the job, how they are doing, how they can improve, what latitude they have in changing how they do their tasks, what should be discussed with a supervisor and when the discussion should occur. Employees rarely complain about too much communication with their supervisor. They often want more communication.
