Six Sigma Catapult Project

For the final project of the Six Sigma Methodology class at Arizona State University (which also certified me as a Six Sigma Green Belt) our team of 6 conducted a project based on the famous Six Sigma Catapult experiment. This project was used to conclude the significant effects of the catapult and also a model was derived to make sure a target was hit at any particular point in a predefined area.

We were restricted to a total of only 45 shots for the whole process so this was interesting as we had to decide how to break up the shots we were going to take. We went with

  • 10 shots for the initial trial and error
  • 16 shots for the 24-1 experiment
  • 19 shots for optimization and verification

We learned a lot during this experiment and were surprised by the results we obtained as they were pretty accurate. The final competition of the class consisted of a target being placed at a random point allocated on the area shown below according to the discretion of our professor and us having to hit the target based on the experiments we conducted and the model obtained. If my memory serves correct from class, I believe we were runner ups for the final competition and won the overall class competitions that were held throughout the semester.
