Exam 15: Appendix: Quality Management

A manufacturer made a commitment to supply 20 units of a product. The first unit took 1,200 hours to make, the second unit took 900 hours, and the third unit took 768 hours. How many hours should it take to make the 20th unit?

Predetermined time standards are advantageous since they avoid needing multiple performance ratings.

A manufacturer made a commitment to supply 20 units of a product. The first unit took 1,200 hours to make, the second unit took 900 hours, and the third unit took 768 hours. Determine the total number of hours required to make the first ten (10) items.

Define time study and describe the basic procedures for conducting a time study.

Discuss the two different sides of the debate over work standards.

Describe an experience curve.

A method of randomly observing work over a period of time to obtain a distribution of the activities that an individual or a group of employees performs is called _____.

Consider the following time study data. $\text { Observation Cycles (Actual Time in Minutes) }$ Work Task 1 2 3 4 5 6 7 A 0.12 0.17 0.19 0.11 0.15 0.16 0.20 B 0.91 0.95 0.97 0.88 0.86 0.80 0.94 C 1.52 1.48 1.40 1.60 1.65 1.52 1.47 a. If the performance rating factor for A = 1.15, B = 1.0, and C = 0.85, determine the normal time for the job. b. If personal allowance is 7 percent, fatigue allowance is 12 percent, personal delay allowance is 9 percent, and avoidable delay is 4 minutes, determine the standard time for the job.

Allowances include time for all of the following EXCEPT:

A performance rating factor (PRF) of 130 percent means that a worker is slow and needs 30 percent more time.

A job had a normal time of 2.43 minutes, an allowance of 20 percent, and a forecast demand of 120 units per day. How long should it take to produce one day's output?

The _____ states that the cost of doing any repetitive task, work activity, or project decreases as the accumulated experience of doing the job increases.

The Chester Table Company mass produces quality end tables for motels. They produce 5,000 end tables per week. The owner is trying to determine how many workers he needs. The workers work 40 hours per week but are idle about three percent of the time because of the cleaning of their area. Their performance rating is equal to one. The owner has developed these time standards for operations per table: Transporting the table through the plant = 2 minutes Table top = 10 minutes One leg = 4 minutes Finishing = 5 minutes a. How long does it take (in minutes) to produce one table? b. What is the labor standard (in minutes) for this operation? c. What is the minimum number of workers needed to produce 5000 tables in one week?

Determine the sample size for the following time study given a standard deviation of three ounces and a 92 percent probability that the value of the sample mean is within two ounces?

The manager at a sewing factory uses a piece?rate pay system. She has just received an order for 600 dresses from a discount house downtown. She is trying to figure out what her costs are for the project. She has conducted a time study and found the following times for operations: 2 minutes to sew one sleeve 3 minutes to sew body of the dress 3.5 minutes to hem all unfinished edges 1 minute to attach the collar 3 minutes to attach all buttons The workers must sit idle while they wait for supplies on the conveyor belt for an average of 30 seconds. Their performance rating is equal to one. She pays the workers $6.00 per hour. a. What is the allowance factor for the operation? b. What is the labor standard (in minutes) per dress? c. What is the labor cost per dress? d. What is the labor cost for the entire order of 600 dresses?

Based on data from a work-sampling study, an office worker spends 21.5 percent of his time filing. Over the work-sampling period, he was idle 12 percent of the time. If the worker filed 420 items in a 40-hour workweek while performing other activities, and if his performance rating factor for filing was 0.95, determine the standard time, in minutes, he took to file an item.

Explain the concept of learning curves using an 80 percent learning curve as an example.

A company manufactures tractors and lawnmowers. They have received an order for six deluxe custom riding lawnmowers for a local golf course. They must develop a cost estimate for the order. It is estimated that the first lawnmower will take 90 hours of shop time and a 75 per-cent learning curve is expected. The labor rate is $18.00 per hour, and the pricing policy of the company is to charge 2.5 times the cost of labor for the order. a. How many hours should the sixth lawnmower take? b. How many labor-hours should the whole order take? c. What is the customer's price for the whole order? d. What is the price per lawnmower? e. If the original time estimate for the first lawnmower is too low, and it actually takes 80 hours for the third lawnmower, what is the labor hour estimate for the first unit? f. If it actually really takes 80 hours for the third lawnmower, what is the new total labor cost for the entire order?

A yacht manufacturer signed a contract to build five sailboats for a California resort. Assuming an 85 percent learning curve, how many labor-hours will it take to build all five sailboats if it took 7,000 standard hours to build the original sailboat?

Which of the following is NOT a practical issue when using learning curves?
