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 $(3$ marks$)$

Summarize the entire report in $1$ or $2$ 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 $(40$ 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 $(2)$

What process capability are you analyzing?

Example: $$McDonald$$s Drive$-$Thru$$ is not a process capability. $$Capability of meeting Customer Service Time at McDonald$$s Drive Thru$$ is$.$

What are the customer specifications?

Process Data $(2)$

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 $(32$ pts$.)$

Process Capability Sixpack $(2)$

Perform the process Capability Sixpack and present it in the report.

Normality Analysis $(2)$

Is the data normal? Explain your answer and show evidence.

Process Stability Analysis $(4)$

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 $(4)$

Examine the Process Spread in detail. Show evidence.

Assess the center of the process in detail. Show evidence. Body of the Report $($cont$...)$

c$.$ Process Capability Analysis $($cont$...)$

Process Capability Results and Analysis

Analyze the Process Capability results $($Within Std$.$ Dev, Cp$,$ Cpu, Cpl$,$ Cpk$)(5)$

Analyze the Process Performance results $($Overall St$.$ Dev, Pp$,$ Ppu, Ppl$,$ Ppk$)(5)$

Compare Cpk with Ppk $(2)$

Explain the Sigma level, Predicted Yield and Expected Process Fall Out $(3)$

Is this process CAPABLE? Explain your answer $($based on a Cpk target of $1\mathrm{.}33)(5)$

d$.$ Evaluate the effect of the measurement system error on process capability $(4$pts$.)$

What is the true Cp if the measurement system $\%$GRR is $10\%?(2)$

What is the true Cp if the measurement system $\%$GRR is $30\%?(2)$ Conclusions & Recommendations $(8$ marks$)$

Much like the executive summary the conclusion summarizes what the report is about and what you have concluded from the data presented. State all your relevant conclusions and justify each one with the relevant data$/$calculation$/$statistic$.$ Include a recommendation based on your analysis.

Summarize the results of your analysis $($normality$,$ stability, capability$).$ What would you tell the process owner who paid you to analyze their process? $(3)$

What should they expect in terms of yield, defects, and customer satisfaction? $(3)$

Make recommendations to improve process capability $$ what should be done next? $($Based directly and specifically on the results and analysis $$ not opinions or invention!$)(2)$

Grammar and spelling $(4$ marks$)$

References

Please list all the references that you used CpTV is the observed potential capability $($Cp$),$ which is the Cp reported in the capability study,

in the above process capability study CpTV $=1\mathrm{.}46$

So$,$ if the above is the reported capability plot, then

For a $\%$GRR of $10\%$: The true Cp $=$ CpTV$/$sqrt$(1-$RR$2)=1\mathrm{.}46/$sqrt$(1-0\mathrm{.}12)=1\mathrm{.}47$

For a $\%$GRR of $30\%$: The true Cp $=$ CpTV$/$sqrt$(1-$RR$2)=1\mathrm{.}46/$sqrt$(1-0\mathrm{.}32)=1\mathrm{.}53$
