Approaches to job design
According to Hannaway & Hunt (1995), approaches to job design include engineering approach, human approach and the job characteristics approach. These three approaches are very important because they ensure increased production within organizations in one way or the other.

The three approaches to job design should be discussed briefly so that one can understand how they are important toward employee motivation. In the engineering approach, task idea was the most prominent element imagined by FW Taylor. According to this approach, every employee's work should planned by the management earlier, and each employee is given complete written instructions which describe in detail the chore to be accomplished. The task specifies what to be done, how it should be done, and the exact time it is allocated. Employees should be offered with thorough training regarding the job, successful job performers are rewarded by monetary compensation, and employees should be assigned jobs that match with their capabilities.

The human approach of job design aims at designing the most rewarding and interesting jobs. This approach ensures that employees are constantly motivated by ensuring that they are well recognized, the working conditions are clean, presence of favorable inter-personal relations, and when they are assured of job and pay security. According to Hackman and Oldham's job characteristics approach theory, employees will work to their best given that they are positively rewarded for the work done, and when they get satisfaction from the work. This approach addresses employee independence, effective communication between employees and employers, and job satisfaction. Through these, the employees remain motivated and therefore work hard for increased productivity.
