Quantitative Exercise 1 -Statistical Process Control | | June | Quantitative Exercise-Statistical Process Control EXERCISE 1 ASSIGNMENT: Six Sigma Definition and Analysis Each student is to complete the following problems from the text: 1. Prepare a SIPOC flowchart (Exhibit 9.5) of the major steps in the process of boarding a commercial flight. Start the process with the passenger arriving curbside at your local airport. a. Introduction/Justification –If we are to create a SIPOC flow chart of the major steps in the process of boarding a commercial flight and we want to start the process with the passenger arriving curbside at local airport, there are 7 steps in the process in my opinion. Before the flowchart let’s take a look at this technique and why we use it. SIPOC (supplier, input, process, output, customer) in essence is a formalized input-output model, used in the define stage of a project, which is the ”D” part of DMAIC methodology. At this case, a SIPOC diagram provides a visual description of airplane boarding. It helps communicate inside and outside of the airline company. In SIPOC analysis it is very clear about where the process starts and where the process ends, which helps define the boarding project scope and so it’s a very good tool here. b. Calculations &amp; Answers –Here we separate the process of boarding a commercial fight into 7 steps and developed a SIPOC Chart. So the completed SIPOC Flow chart is below: c. Interpretation –This chart establishes project scope and is very clear about where the process starts and where the process ends. Usually SIPOC chart is within 5 steps while we use 7 steps instead of within 5 steps is because each step is performed at different time commonly and is best not to combine them. This will help the OM team visually see the process and define the project scope; it will help
