This control chart project gives you the opportunity to illustrate your expertise of how to implement chapter five topics. You have undertaken a mini version of this in the form of the yardstick experiment. In this project, you get to select the process to measure, construct a control chart off of it, and determine the process capability.
The basic idea behind the project is for you to use the techniques learned in class to investigate a process, analyze the causes of variation, and make recommendations for improvement.
There must be a definable time sequence with regard to the data used for this project. Normally, this means that you must know the sequence in which the item or service was produced.
Your data set must include at least 25 subgroups. For an I-MR chart, only 25 data points are needed because n=1. For a Xbar and R chart, you will need more than 25 data points to form 25 subgroups because n>1.
This data must be derived from a face-to-face meeting(s) with a company (you may not just go to the internet to gather the data). Data that is not developed using this methodology is unacceptable and the project will receive a zero.
Please use the subject headings below to format your paper. Of course, content is important. However, grammar, spelling, punctuation, and format will be considered as well. Tabular and graphical data must be properly labeled, presented, and referenced in the report to support your findings. Use third person!
A graded 2-4 minute PowerPoint presentation is required on the due date.
Assume a quality management audience; one that is informed of quality techniques, but not of your particular project.
Use the following section headings for the paper. The content of your report should include:
I. Introduction
Give a complete description of your experiment in terms of the physical process and the data gathering process. Be sure to address topics such as the time the data was gathered, place, data gathering equipment used, problems in data gathering, assumptions made, etc.
II. Tabularized Data
III. Findings
Using Minitab software, generate a capability six-pack. Interpret each section of the six-pack. Be sure to explain your rationale for selecting the USL and/or LSL. Also, state whether or not the process is in control and justify your decision. In addition, explain any causes of variation and how they could be removed.
IV. Recommendations
In addition to the recommendations based on the findings, discuss what you would do differently if you conducted the experiment again.
