$5.)$ Recreate the control chart omitting any points of special cause variation you identified above.

Once the process is stable $($why do we need a stable process first $$ take a moment to think about this$),$ we can begin to analyze the main drivers of defects.

Correcting Common Cause Variation

II$.$ Analyzing Problems

$1.)$ Create a Pareto diagram of all the defect categories. Interpret the chart.

$2.)$ Which defects occur in the highest frequency?

$3.)$ Does it make sense from a process standpoint to combine any categories together? Create a new Pareto diagram with these categories combined. Interpret the chart.

$4.)$ If the frequencies of some categories of defects are combined, which two represent the highest percent of defects?

$5.)$ What would you recommend to We$$re All Screwed as their next steps for improving their process capability?

III. Professional Report

$1.)$ Write a ~$2$ page report with an appendix $($control charts, pareto diagrams$)$ for We$$re All Screwed$$s senior quality improvement staff summarizing your findings and recommendations from Part I and II$.$ This is the only item from Part I and II that needs to be submitted on Canvas.

a$.$ A rubric has been provided below.

IV$.$ Group Presentation

$1.)$ Prepare a $10-15$ minute professional PowerPoint presentation to We$$re All Screwed$$s senior quality improvement staff summarizing your findings and recommendations from Part I and II$.$ Submit your slides on Canvas.
