A process at a watch assembly plant has been changed. The process is divided into three work elements (see table below). A time study has been performed with the following results. The time standard for the process previously was 14.5 minutes. Based on the new time study, should the time standard be revised (essay & calculation format)? The new time study had an initial sample of four observations, with the results shown in the following table. The performance rating factor (RF) is shown for each element, and the allowance for the whole process is 18 percent of the total normal time.
