Quality Control Systems

Course Project

Instructions:

In this project, you will propose a method by which to monitor the quality of a process or system within your organization. Then, you will use statistical process control methods to evaluate the process. Finally, you will determine whether the process is capable and propose a strategy to decrease potential sources of variability.

Except as indicated, use this document to record all your project work and responses to any questions. At a minimum you will need to turn in a digital copy of this document to your instructor as part of your project completion. You may also have additional supporting documents that you will need to submit. Your instructor will provide feedback to help you work through your findings.

Note: Though your work will only be seen by those grading the course and will not be used or shared outside the course, you should take care to obscure any information you feel might be of a sensitive or confidential nature.

Complete each project part as you progress through the course. Wait to submit the project until all parts are complete. Begin your course project by completing Part One below. Information about the grading rubric is available on any of the course project assignment pages online. Do not hesitate to contact your instructor if you have any questions about the project.

PART ONE

Set Specification Limits

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

The first steps of designing a quality control system are determining what to measure to ensure quality and setting specification limits that determine what the measurements should be$.$ In part one of the course project, you will identify and describe a process in your organization, and propose a quality control variable for it$.$ Then you will set specification limits for that variable. If you are not currently working within an organization, choose a process in which you$$re the customer or consumer.

To complete this part of the project you will:

$1.$ Choose a process in your organization that you want to evaluate for quality OR a process in which you$$re the customer or consumer. Write a thorough description of the process.

$2.$ Recommend at least one quality control variable to be used as a proxy to determine the process quality.

$3.$ Indicate how each quality control variable should be measured.

$4.$ Set the design specification limits for each control variable you selected, and provide the business rationale behind each of them.

Describe the process in your organization $($or the process in which you$$re the customer$)$ that you want to evaluate for quality. Be specific. Consider providing a process flow diagram.

In the table below, recommend at least one quality control variable and indicate how you plan to measure it$.$ Then, set upper and lower specification limits for each variable, and provide the business rationale behind each of them.

PART TWO

Use Statistical Process Control Tools to Evaluate a Process

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

In part two of your course project, you will use statistical process control $($SPC$)$ tools to evaluate either the process you identified in part one or a hypothetical call center process.

In order to evaluate the process you identified in Part One, you must be able to collect sample data that meets the following standards:

$8-12$ samples of your control variable

$$ Each sample contains $3-5$ data points $($e$.$g$.,$ duration, volume, weight, etc.$)$

To complete this part of the project:

$1.$ Open the Mean Chart and Range Chart tools.

$2.$ If using the hypothetical call center data, download the $$Call Center Data$$ file from the Project: Part Two course page in Canvas.

$3.$ Input the data you$$ve collected from your own process OR input the sample data from the Call Center Data file into the sample charts in the Mean Chart and Range Chart tools. Note: You will need to adjust the calculations to include the number of samples you are using.

Answer the following questions. Use as much space as you need.

Which process are you using, the process from Part One or the hypothetical call center process?

After you have entered the data into the Mean Chart tool, copy your mean chart and paste it below.

Is the process in control with respect to the means? How can you tell?

After you have entered the data into the Range Chart tool, copy your range chart and paste it below.

Is the process in control with respect to the range? How can you tell?

Save your work. You will submit your course project for feedback and grading after you complete
