1)Do you recommend that the four machine operators continue to switch machines every hour? Would you recommend that the operators are permanently assigned to the machines they currently operate during Hour 3? What do you think would be the consequences of any changes you might recommend? 2)How can the principles of the mechanistic approach to job design inform a decision about how to assign workers to machines? What about the principles of the motivational approach? The perceptual approach? The biological approach? 3)How could job analysis be used to improve this assembly line?
