Question 1 (1 point) What kind of cost involves checking the product or service during its manufacture or provision? Appraisal Cost Intangible Cost Failure Cost Prevention Cost Navi Dao Dana Question 2 (1 point) How does a reduction in the costs associated with poor quality result in an improvement in a company's profit performance? If a company is spending significant funding to rework a product or redo a service, then this is money that is being spent unnecessarily. Reducing costs of poor quality increases the likelihood of repeat or new business. The cost associated with ensuring quality outweighs any possible benefit to the company. All of the above A&B Question 3 (1 point) Which of the following statements best describes total quality cost? Prevention costs & intangible costs The total added to invoice for added quality measures for services rendered Internal and external error costs Prevention costs, appraisal costs, failure costs, intangible costs There are 3 components to a balanced Scorecard.

True False Previous Page Next Page Page 4 of 26 Question 5 (1 point) John has just been hired as a color separator in a printing company. John is familiar with many types of separators, but each has its own processes that must be learned. The person doing the hiring assured John that a training program was in place. John's first day at work was a disaster. He was assigned to separator 3 and told to "run it. When he explained to the supervisor that he needed some training to get up to speed on the machine, the supervisor grudgingly asked another employee to spend 15 minutes with John. Wanting to get back to her machine, the other employee gave a quick 5 minute run through and John was on his own. John made many mistakes that first night and production was lost. His supervisor thinks John won't make it through his probationary period. What costs of quality have been incurred? External failure costs (employee satisfaction) Internal failure costs (waste of time and effort) Intangible costs (potential loss for a job incorrectly done) Prevention costs (probationary period) Employee training is a measure of internal process measurement. True False Question 6 (1 point) Employee training is a measure of internal process measurement. True False Previous Page Next Page Page 7 of 26 Question 7 (1 point) 1. Recently, a customer in a store purchased over $100 worth of household cleaning supplies. As the clerk bagged the purchases, the customer notice that the bags were flimsy and the items (laundry soap, detergent, cleanser, furniture polish, bleach, ammonia, etc.) were rather heavy. The customer requested that the items be separated into several different bags and double-bagged to avoid ripping the bags. Though the store was not busy and no one else was waiting in line, instead of complying with the customer's request, the clerk hefted the bag in the air and said "it should hold up". The customer insisted, but the clerk refused to double-bag or provide more bags. As the customer left the store, several of the bags ripped. The customer ended up returning for bags and re-bagging the items without the aid of the clerk. The customer has decided not to patronize the fore in the future. What costs of quality did the customer incur? What costs of quality did the provider of the product or service incur? External failure costs (cheap bags) External failure costs (poorly trained clerk, no customer service) Prevention cost (Is anyone telling purchasing that the customers are upset about the bags?) bandalavahvendo this Question 8 (1 point) Another name for a why-why diagram is a fishbone diagram.
