Final Exam Essay

13. Which of the following characteristics makes it EASIER to measure the quality of a service, relative to that of a product or facilitating good?

Quality Associates, Inc., a consulting firm, advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes. IN one particular application, a client game quality associates a sample of 800 observations taken during a time in which that client's process was operating satisfactorily. The sample standard deviation for there data was .21 ; hence, with so much data, the population standard deviation was assumed to be .21. Quality associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. BY analyzing the new samples, the client could quickly learn whether the process was operating satisfactorily. when the process was not

A process that monitors standards by take measurements and corrective action as needed. It is in control when only variation is natural, if variation is assignable then discover cause eliminate it. Take samples to inspect/ measure- reduce inspection time, reduce opportunity of bad quality. Control charts graph of process data over time-show natural and assignable causes. Control charts for variable data (characteristic that is measured, length,height, etc) are X-chart (average) and R-chart (range)must use x and r to get correct results. central limit theorem follow normal curve. When we know . When we don’t know . Control charts for attributes (categorical-defective, good/bad) P-chart (percent) or C-chart

Question 2. 2. (TCO G) Explain the concept of the cost of quality model and then link your explanation to how quality can be defined by organizations. What are some advantages and disadvantages of the cost of quality model? This answer must be in your own words—significant cut and paste from the text or other sources is not acceptable.  (Points : 30)

C. Quality: The degree to which a product or service meets customer requirements and expectations.

7) Quality can improve profitability by reducing costs. Which of the following is not an aspect of reduced costs by quality improvements?

5.  Assuming that operators will continue to take samples of 10 sheets each hour to check if the process is in control, what control limits should Douglas set for the case when extrusion is a Six Sigma process?

Back in the olden days, the success of an organisation was determined by the quality nature of products they provided their customers. It was believed that customers were ignorant and did not know exactly what they want and therefore accepted whatever was given them; thus the final decision rested on the producer or service provider. The case however, in today’s business environment is the reverse of the above mentioned. Due to technological advancements, increased competition and the fact that people have become more informed and knowledgeable, customers now determine exactly what

Traditionally, Service quality can be portrayed as the result from client comparison between their assumptions about the service they will use and their insight about the service company. That implies that if the insight recognitions would be higher than the desired the service will be considered as fabulous, if the desires rise to the insight observations the service is viewed as great and if the desires are not met the service will be viewed as awful. For a service to be considered as good the organisation is required for making customers satisfied and service quality should be associated with customer perceptions and expectations. (Carlsson, 2010)

Control – the necessary amount and type of control/s having been computed are then enacted at the appropriate point/s in the input-throughput-output process.

Presented in the following lines will be the three data control categories, two specific controls and how each of the controls contributes to ensuring that the data is reliable. This problem is divided into three different controls: Input, Processing and Output.

The statistical process control system involving both acceptance sampling and automated process control was to be implemented. SPC involved testing for productions within a pre-specified range. If the production went beyond the range, the production process had to be shut down maintenance was to be called to perform maintenance and recalibration. As a part of the process, the operators were to take six random measurements of a process characteristic during the course of their shift and then plot the mean measured value.

Customers realize that the current system is not flawless. Companies see that providing better service quality will create and obtain the customers loyalty, continuation of business and enhance the quality of the organization. Service quality is suppose to be consistent, reliable and accountable

1. What control charts should be used to determine whether the process is in control or out of control?

“A product or a service possesses quality if it helps somebody and enjoys a good and sustainable market.”
