Using Paper Helicopters to Teach Statistical Process Control.

TLDR: This hands-on project uses a paper helicopter to teach students how to distinguish between common and special causes of variability when developing and using statistical process control charts.

Abstract: This hands-on project uses a paper helicopter to teach students how to distinguish between common and special causes of variability when developing and using statistical process control charts. It allows the student to experience a process that is out-of-control due to imprecise or incomplete product design specifications and to discover how the process can be brought into control through the use of standardized product specifications and associated construction procedures. It also allows the student to experience common causes of variability, to distinguish these from the special causes of variability resulting from the incomplete design specifications, and to discover how standardization reduces process variability. The project has been used in both undergraduate and MBA classes and demonstrates these concepts in a way that is easy for the student to understand and remember.
