The catapult (often the Statapult®) is a hands-on training tool in Six Sigma workshops.

Training Purpose

It simulates a multi-factor process where teams adjust variables like arm angle, rubber band tension, and launch height to hit a target distance consistently. This demonstrates variation sources—both common (random) and special cause—through repeated launches.

Six Sigma Applications

• DMAIC Practice: Define target specs, measure shots, analyze data (histograms, control charts), improve via DOE (design of experiments), control with standard work.

• Key Lessons: Shows interactions (e.g., angle × tension), regression modeling, ANOVA, and capability (Cp/Cpk) in real time.​

• Engagement: Teams compete to minimize variation, making abstract stats tangible without complex setups.
