DF-5 Deming Funnel Experiment with Text Book
Many have thought that Dr. Deming's Red Bead experiment was powerful in helping people recognize their simple-mindedness when it comes understanding variation. An even more powerful demonstration for showing the futility of adjustments, tampering, random walks, oscillation and a variety of other concepts is the Funnel Experiment. The experiment was actually developed by a cohort of Dr. Deming and is applicable to a variety of business situations such as machine adjustments, automatic compensating routines, calibration, reacting to accidents, worker training, performance appraisals and much more. The unit is designed to be used with a gridded chart pad (not included, but readily available at office supply store. ) and comes with a Funnel, Stand, Ball, and copy of The Deming Dimension in which Chapter 5 is entirely devoted to explaining the experiment and the four funnel rules. The funnel also has a set of cross hairs in the base for accurate placement during the experiment.
