6. A process at a watch assembly plant has been changed. The process is divided into three workelements (see table below). A time study has been performed with the following results. Thetime standard for the process previously was 14.5 minutes.Based on the new time study, should the time standard be revised (essay & calculationformat)?The new time study had an initial sample of four observations, with the results shown in thefollowing table. The performance rating factor (RF) is shown for each element, and theallowance for the whole process is 18 percent of the total normal time.Element 1Element 2Element 3Obs 1 Obs 22.602.344.944.782.181.98Obs 33.125.102.13Obs 42.864.682.25Average (min)2.7304.8752.135RF Normal Time1.01.10.92.7305.3631.922
