The continuous stopwatch timing method was used to obtain the observed times for a worker-machine task Only one cycle was timed. The data are recorded in the table below. The times listed indicate the stopwatch reading at the end of the element Elements a, b, and d are worker-controlled elements. Element is machine controlled. Elements a and d are external to the machine-controlled element, while element is internal Every four cycles, there is an irregular worker element that takes 1.44 min rated at 100% performance. For determining the standard time, the PFD allowance is 15% and the machine allowance is 30%.
