Process: Fill a cup with water. Characteristic: time it takes to fill the cup with water. Prepare a formal technical report of your process capability analysis using the collected data Cover page: No marks Assignment name, Course Name and section, Group # Student Names, Date Executive Summary marks Summarize the entire report in or concise paragraphs summary of results, conclusions, and recommendations A person should be able to read this summary, and know what you did, why you did it and what your conclusion is Body of the Report marks Use headings to separate the sections within your report, but make sure the headings define what you are going to say in that section. This section should be an explanation of the data and analyses. If extensive data and analyses are required include them in an appendix. Suggested headings: Process Description What process capability are you analyzing? Example: McDonalds DriveThru is not a process capability. Capability of meeting Customer Service Time at McDonalds Drive Thru is What are the customer specifications? Process Data Provide a table with the collected data. Clearly state how the data was collected: sample subgroup size, sample frequency, unit of measure, total number of subgroups collected. Body of the Report cont Process Capability Analysis pts Process Capability Sixpack Perform the process Capability Sixpack and present it in the report. Normality Analysis Is the data normal? Explain your answer and show evidence. Process Stability Analysis Is this process stable? Explain your answer and show evidence. Explain if you decide to remove any special causes and reassess stability. Show evidence. Histogram Analysis Examine the Process Spread in detail. Show evidence.
