Objective: So far--so good. The process has been in control for the past four months. Phyllis isn't as well versed in Six Sigma as the team is, and it is her nature to question everything. She asks for a capability study to be performed on these parameters and asks for a calculation two key factors that affect thickness and wants to see this for the past 35 days of production. You are on the spot, but confident. You pull up the past 35 day's worth of data and you calculate Pp and Ppk for each. Is Phyllis going to be happy or is she going to be more skeptical? That is the 'question of the day.' Crunch the numbers--and you will find out. By the way--finish this deliverable AND MAKE ALL OF THE CORRECTIONS REQUIRED ON THE PREVIOUS ASSIGNMENTS and you are finished with the project! Congratulations!!! Instructions for you: "Is it possible for me to do a self-check?" Instructions for you: 1. Construct histograms for each of the parameters. Note: The first parameter 'thickness' is the product parameter. The second parameter is thought to affect thickness. 2. Are the processes approximately normally distributed? 3. Calculate Pp and Ppk for each. Note: The upper and lower specifications are listed at the bottom of each column. You will need these to do the calculations. 4. Are the processes acceptable?

DO NOT SEND THE ACTUAL HISTOGRAMS UNLESS YOUR INSTRUCTOR ASKS YOU TO. Project: Deliverable: Pp Ppk Student last name: INSTRUCTIONS: (1) IF YOU SAY THE DISTRIBUTION IS NOT APPROXIMATELY NORMAL, GIVE THE CORRECT NAME FOR THE PATTERN YOU SEE IN YOUR HISTOGRAM. (2) BASE YOUR DECISION ON ACCEPTABILITY ON THE ASSUMPTIONS AND CRITERIA FOR Pp and Ppk DISCUSSED IN THE RECORDED LECTURES AND VIRTUAL CLASSES ON CAPABILITY. YOU DO NOT NEED TO CREATE CONTROL CHARTS FOR THIS ASSIGNMENT!! Thickness Pp (use 6 decimal places) Ppk (use 6 decimal places) Is this distribution approximately Normal? If it's not normal, what is the shape? Is this process acceptable? Explain your decision on acceptability. 2.111442 2.093347 Yes Yes yes-acceptability because variation CPK>0 Round your Pp and Ppk results to 6 decimal places. R.P.M. Pp (use 6 decimal places) 7.552945 Ppk (use 6 decimal places) Is this distribution approximately Normal? If it's not normal, what is the shape? Is this process acceptable?

MAL, GIVE THE CORRECT ON ON ACCEPTABILITY RDED LECTURES AND L CHARTS FOR THIS Check HINT! HINT! HINT! ecause variation CPK>0 Check HINT! HINT! HINT! INT: These calculations generally require that two assumptions be met, particularly Cp/Cpk. Since we are at the end of the project, we would like to meet both of these. What are these assumptions and do these histograms meet them? (Use the histograms ecause variation CPK>0 to decide.)
