Repeatability and Reproducibility
For the process you chose (for your term project) in 1-3, write a report of 200-400 words about the repeatability and reproducibility of the measurement system. Address the following issues: What data must you collect? Who will collect the data? How do you trust that the data is accurate?
The Measure Phase
Instructions
For the process you chose in 1-3, set the following values: process target (Ï ), upper specification (U), and lower specification (L). Then take appropriate samples to estimate the process mean (µ) and the process standard deviation.
Calculate the following for your process:
Defectives per Million Opportunities (DPMO)
Yield
Process capability ratio (Cp)
Process capability index (Cpk)
The Analyze Phase
Instructions
Using Minitab and/or a cause-and-effect diagram, identify the root cause of the problem you are trying to solve for the process you chose in 1-3. Also, construct a main effects plot, if applicable.
Statistical Process Control
Instructions
For the process you chose in 1-3, identify the type (variable or attribute) of data you have collected for the outputs of interest. Construct the appropriate control charts, based on the knowledge gained from the Module Six overview. Ensure that your data is stable before proceeding to the Analyze phase of your Six Sigma term project.
The Improve and Control Phases
Instructions
Refer to the root cause you identified in 6-4. Prepare a plan to improve the process by eliminating the root cause. Estimate the time and cost involved. Also, document potential risks during the improvement process and prepare risk responses for the same.
