There is little benefit in applying work study to work which is temporary or which, for some reason or other, is expected to be short-lived. The economic results of the study, whether they are increase in output, reduction in scrap, improved safety, reduction in training time, better use of equipment or labour etc. should always outweigh the cost of the investigation.
Kuna faida kidogo katika kutumia utafiti kazi ya kufanya kazi ambayo ni ya muda au ambayo, kwa sababu fulani au nyingine, anatarajiwa kuwa muda mfupi. matokeo ya kiuchumi ya utafiti, kama wao ni ongezeko la pato, kupungua kwa chakavu, kuboresha usalama, kupungua kwa muda wa mafunzo, matumizi bora ya vifaa au nk kazi lazima daima outweigh gharama za uchunguzi.
