EMM 314: Manufacturing Work Study Revision Questions with Worked Solutions

Question sets for the unit with the calculations worked through. The questions cover why a job is chosen for methods study, the areas to focus on when improving work methods, the reasons for excess work content arising from defects in design or specification, what work measurement achieves, the advantages of work sampling over time study, the predetermined time study approach, and the principles of motion economy as they apply to the human arms and body. The solutions take a work sampling study over five days at eight hours a day with ten operators, fifteen per cent allowances and six thousand components produced, and carry it through observed time to effective time, normal time at a performance rating of one hundred and twenty per cent and the standard time, alongside a stop-watch study of five elements rated at eighty to one hundred and ten per cent.
