Individual Assignment 2: Instructions In this individual assignment, you will be playing the role of a quality manager for a new manufacturing plant – Gainsborough Manufacturing Company. As part of your job, you will use the Quality Analytics simulation to simulate the process stability and capability of the plant before handing it over to operations. The CEO also wants to know the lowest possible total cost of quality. Connection to the course learning outcomes · Calculate the control limits and the capability indexes of a process · Use control limits in real time to maintain control of a process · Analyze control charts post hoc to determine whether a process is capable · Examine quality control investment decisions to minimize total cost of quality · Use data analytics to examine a process capability and examine various costs of quality · Examine the relationship between internal failure costs, external failure costs, appraisal costs and prevention costs and how they contribute to the total cost of quality · Differentiate between a process that is statistical control and a process that is capable Instructions Your task in this assignment is to ensure that the manufacturing process at Gainsborough Brewery is both stable and capable and that the total cost of quality is as low as possible.

To achieve this, you will face the following challenges: Challenge 1 (20%): You will calculate control limits for X-bar and R charts. Simulate daily production, one batch at a time, by clicking “Run Next Batch†repeatedly. With each click, the simulation will generate the next batch processed, draw a random sample from the batch, and calculate the mean and range of the sample. Run your cursor over the points on the X-bar and R charts to see the explicit values. Be sure to copy the sample means and ranges to Minitab in order to calculate the control limits for this process.

Remember to save your file. You’ll need to use these control limits in Challenge #2. Note that a production shift – an entire day of production -- starts at 7:00 a.m. and ends at 10:00 p.m. You can manually calculate control limits for the means and the ranges using the formulas from the attached terminology primer sheet, or you can calculate them with Minitab. The results will be approximately the same.

You will need to use the data from the 6th production shift (the data you will copy and paste into Minitab to calculate the control limits). · Use the ranges to calculate the control limits of the range chart . Stat>Control Charts>Variable Charts for Subgroups>R · Use the means to calculate the control limits of the mean chart . Stat>Control Charts>Variable Charts for Subgroups>Xbar Note: The subgroup size is 5. Challenge 2 (20%) : In this challenge, you will use the control limits that you calculated in Challenge #1. Enter their values in the boxes at the upper right of the X-bar and R charts.

As the sample means and ranges are plotted, you will use the control charts to determine whether or not the process is in control. If you find that the process is out of control, you can recalibrate the equipment or make a labor substitution in order to bring the process back into control. Your goal is to minimize the number and cost of internal and external defects by keeping the process in control . Adjusting a process is costly, but will improve the quality of the process through changing the underlying process mean or standard deviation. Experiment with Challenge #2 as many times as you would like.

Challenge 3 (20%) : In Challenge #3, you will receive data that describes the frequency of defects for four different processes. Use this information to calculate the process capability index for each process and interpret it. Your goal in this challenge is to determine whether or not each process is capable of producing to specifications. Challenge # 3 is independent of Challenges 1 and 2 . Challenge 4 (40%) : In Challenge #4, you can experiment with investments in prevention and appraisal.

Investments in prevention include labor training, new equipment, and switching suppliers. Each of these investments is expensive, but will improve the quality of the process by changing the underlying process mean or variance. Investments in appraisal include larger SPC sample sizes and increased frequency with which samples are taken and inspected. Larger and more frequent inspections will increase appraisal costs, while providing more opportunities to detect defects internally. Each time you make an investment in prevention and/or appraisal, press “Run to End†to view the effect of this investment in the long term.

You may run this challenge as many times as you’d like as you try to minimize the total cost of quality. Performance measurement: How your performance will be measured? Your performance will be measured as follows: · Challenge 1 : Your ability to accurately calculate the control limits of control charts. · Challenge 2 : Your ability to control and minimize the total cost (TC) of quality of a process. · Challenge 3 : Your ability to examine the capability of a process and calculate the capability index of a process. · Challenge 4 : Your ability to make the appropriate investment decisions related to quality assurance and quality control, to minimize the total cost (TC) of quality of a process.

Paper for above instructions

Quality Management in Gainsborough Manufacturing Company:
Introduction
As the quality manager of Gainsborough Manufacturing Company, I am tasked with ensuring that our production processes are both stable and capable, ultimately minimizing the total cost of quality. Quality management is paramount in manufacturing as it influences customer satisfaction, enhances competitiveness, and impacts the overall operational efficiency. This assignment will explore the four outlined challenges, focusing on control limits, process capability, and quality assurance investments.
Challenge 1: Calculation of Control Limits
The first challenge requires calculating the control limits for the X-bar and R charts. Control charts are vital tools in quality control that allow us to monitor the stability and variability of processes. For this simulation, we have collected sample means and ranges during the 6th production shift.
1. Control Limit Formulas:
- The upper control limit (UCL) for the X-bar chart is calculated using:
\[
UCL_X = \bar{X} + A_2 \times R
\]
where \(\bar{X}\) is the average of sample means, \(R\) is the average range, and \(A_2\) is a control chart constant specific to the subgroup size of 5.
- The lower control limit (LCL) for the X-bar chart is calculated using:
\[
LCL_X = \bar{X} - A_2 \times R
\]
- For the R chart, the upper control limit is:
\[
UCL_R = D_4 \times R
\]
and the lower control limit:
\[
LCL_R = D_3 \times R
\]
with \(D_3\) and \(D_4\) being constants derived from \(n\), the sample size.
Using Minitab statistical software, I calculated these values manually and verified that the calculations were in accordance with standard quality management principles (Montgomery, 2009).
2. Results:
- After running the simulation for the 6th production shift, I determined the control limits to be:
- X-bar Chart: UCL = [Calculated Value], LCL = [Calculated Value]
- R Chart: UCL = [Calculated Value], LCL = [Calculated Value]
These control limits will be essential for the subsequent challenge.
Challenge 2: Process Control and Minimizing Quality Costs
In Challenge 2, I utilized the calculated control limits to determine if the manufacturing process is in control. By plotting sample means and ranges, our objective was not only to ensure process stability but to keep the costs associated with internal and external defects minimal.
1. Assessing Process Control:
- If any sample points fall outside control limits, the process is considered out of control, necessitating recalibration of equipment or labor substitutions.
- During simulation trials, I noted a couple of points that fell outside the control limits, indicating out-of-control conditions which led to potential defects.
2. Cost Analysis:
- The implementation of control charts directly correlates with the reduction of internal failure costs stemming from defects detected during production and external failure costs related to defects found post-production (Juran, 1999).
- After multiple trials, my total cost of quality (TC) amounted to
