A factory is scheduled to produce 500 units in an 8.5 hour shift that includes a 30 minute lunch period and two 20 minute breaks. No-one works during lunch or breaks. A time study was conducted of a job in order to develop new time standards. A worker was observed for 30 minutes. During that time, 35 units were produced. The analyst rated the worker as performing at a 110 percent performance rate. Since a lunch break and two personal breaks are already scheduled during the shift, no separate allowances are made for personal time. However, the job does require the operator to periodically swap out three different racks of parts. Allowances are needed for this periodic swapping as shown below: Part No. ABC XYZ 123 Units/Container 50 500 250 Time to swap racks 3min 2min 2min.Click here for more on this paper.......
