The Quality Analytics Simulation was designed to perform or conduct four separate challenges:

#$1$ Calculate the Control Limits for the X$-$bar and R graphs. This is where you simulate the daily production of a generic product in order to see how quality metrics are collected. Run the batch repeatedly. After you complete the entire set of runs, go to the Copy Data tab and hit enter or click on it$.$ This will assist in calculating the control limits for this process. Save these because you will need them for challenge #$2$

#$2$ Keeping a process in control while minimizing costs. In this challenge, the upper and lower control limits for X$-$bar and R $($range$)$ of the process are to be calculated; total costs $($includes defects and process changes$)$; # of defects; # of times you substituted labor or recalibrated inefficient equipment, or both. There are attachments within this assignment that will assist you in calculating these limits$.$

#$3$ Determine whether each process is capable of producing to specifications. So$,$ what is the process capability index and is it capable? The calculation for Cp is in the attached document.

#$4$ Can certain investments reduce your total cost of Quality? Total costs can be external failures, internal failures, training, investments in equipment and suppliers, managing the sample size and frequency of sampling, etc. The scatter plot generated will show the cost vs$.$ yield for all runs in the class that will be viewed by me$.$

Assignment: Open and run the simulation as previously mentioned. In the discussion board, respond to one of the questions listed below that have to do with the Costs of Quality. You will learn as you go and have to make certain decisions in challenges $2-4.$ I can set up an optional Teams meeting to discuss this

if necessary. Email me separately and let me know if this is necessary and I will try and manage a time that is suitable for everyone or individually. I am available to meet on campus as well, as I have done in the past for those on campus. I have also attached a guideline that can help you through this simulation.

Discussion board question options:

#$1$ How are the four categories of the total cost of quality related to each other As you made changes in one cost category, what happened to the other ones?

#$2$ How does the total cost of quality change as you make investments in the various quality cost categories?

#$3$ How does the variability of the process change as you made investments in the various quality cost categories?

#$4$ How do you know when the underlying process has changed based on the investments made?
