Standard time = Normal time x (It allowance factor) 58.282 X (1+0.12) 52.282 X 1.12 65.275 6) Time available for making sandwiches 8X60-50 480 - 50 = 430 minutes No. of sandwiches = 430 X 60 = 395.25 65.275 So, there is a need of an more than one accomplish the target of 400 units. employee to If are to be recruited employees needed. new then 2 wokes are Fast & Fresh Pastry Fast & Fresh Pastry generally applies a fatigue allowance of 5%, and a personal allowance of 7%. They pay their employees the equivalent of $10.50 per hour. Discussion Questions Fast & Fresh Pastry is a medium-sized company in Australia, specialized in baking and distributing pastries in high volumes. They serve gas stations, convenience stores, and cafeterias. Their products line includes cinnamon rolls, croissants, bear claws, bis- cuits, buns, and flatbreads. Their processes are highly standard- ized, with the same steps needed for all their products. Recently they had a request from their customers to introduce croissant sandwiches, with ham, lettuce, butter, and mayonnaise in it. They would need to produce 400 units during their 8-hour morning shift. The procedure of making the requested croissant sandwich is simple and the new ingredients are readily available from nearby supermarkets. The company would have to halve the croissant, put the required ingredients in it, package it individually, and stamp the production date and time on it. The issue was that it added a new ele- ment into their well-working process. The management also worried about the number of employees they would have to hire, since the additional labor cost would cut into their already thin profit mar- gin. To estimate the time needed for the additional step, one of their workers (with a performance rating of 115%), performed the task 20 times with the following results in seconds): 1. Determine the job element's normal time and standard time. 2. If the management uses a 95% confidence level and an accu- racy of +5%, is their current sample size sufficient? 3. Is one additional employee sufficient to perform the new job ele- ment and prepare the 400 sandwiches during the morning shift? The workers get one 50-minute paid break during the shift, which is not included in their fatigue allowance. 4. How much labor cost does new job element add to the total cost of one croissant sandwich?
