The error was made by the cable company's specifications provided to the overseas supplier. The operations manager calculates that it would be cheaper to manually change the connectors rather than the supplier re-doing or fixing the cables. The manager observes the first set of workers pulled aside to change the cables and from these observations will set a standard time. The observations are as follows for workers to each change the connectors on sets of 20 cables. n (min) 1 7.17 7.23 3 6.98 4 7.05 5 7.54 6 7.33 7.11 7.27 7.09 10 6.99 Observatio Time The manager will use a performance rating factor of .95 and an allowance factor of .04. .........anager will use to change the connectors. Hint: See the example in the lesson notes. 7. Sample size (10 marks) The operations manager from Q6 wants to make sure the right sample size was used to collect the observations and calculate the standard time. Question 8 follows on the next page. 8. Utilization, efficiency, and productivity (10 marks) The operations manager from Q6 creates an 8 hour shift with a 30 minute lunch and two 10 minute breaks, one in the morning and one in the afternoon. With personal bathroom and other breaks such as stretching, the manager feels the workers actually put in 7 hours of productive time in the shift. The manager uses 3 workers to switch the connectors. After each shift each worker on average produces so sets of 20 connectors a) Calculate the utilization, efficiency, and productivity. b) Comment on if you think the owner will be satisfied or not with the overal productivity? Hint: see the example in the lesson notes
