Funnel Experiment

Adjusting a process that is in statistical control only increases the variation in the process. See how the Funnel Experiment is used to show the dangers in tampering with a process. This animated video reviews variation (common and special causes), demonstrates the four rules for the funnel and gives real life examples of each rule.

I've been using SPCforExcel for a while now and it is fantastic, but the best part is the knowledge I've gained form your videos and articles. I've learned so much from them and use them to educate others and improve our business. Convincing other managers to stop tampering with our processes has been the biggest challenge to stabilizing and improving our process, but with persistent and solid evidence it works. Thanks!

Errata: Out of the Crisis was first published in 1982 and then again in 1986... video says 1968.

You are correct. The video say 1968 instead of 1986. Our apologies for the error, thanks for letting us know.
