Remove plate from fixture and place in rack 0.62 The reading in the table above were taken by the snapback timing method of direct time study to produce a certain subassembly. The task was performance rated at 80%. In addition to the above regular elements, an irregular element must be included in the standard: each rack holds 6 mechanism plates and has universal wheels for easy movement. After completing 6 subassemblies, the operator must move the rack (which now holds the subassemblies) to the aisle and then move a new empty rack into position at the workstation. This irregular element was timed at 2.93 min with the same previous performance rating. The PFD allowance is 10%.
