Funnel Experiment • The Funnel Experiment is a famous experiment first developed by Dr. Deming. It was designed to show primarily two things: 1. All processes have statistical variation 2. Improving processes to reduce variation is infinitely better than trying to control process variation
Funnel Experiment Rule 1: Do nothing Rule 2: Move the funnel in an equal but opposite direction Rule 3: Move the funnel in an equal but opposite direction from (0,0) Rule 4: Move the funnel to the last position where the last hit.

The Funnel Experiment Rule 2: Move the funnel in an equal but opposite direction from where the last marbel hit. The funnel should be moved the distance (-xk,-yk) from its last resting point. Machine/Process adjustment rules using control chart limits. Automatic compensating machinery
Funnel Experiment; Rule 3 4 3 2 1 Yk 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 -3 -4 Xk The Funnel Experiment Rule 3: Move the funnel in an equal but opposite direction from target (0,0) to where the last marble hit. Rule 3 states that the funnel should be moved a distance (-xk,-yk) from the target (0,0).
The Funnel Experiment Rule 3: Move the funnel in an equal but opposite direction from target (0,0) to where the last marble hit. Rule 3 states that the funnel should be moved a distance (-xk,-yk) from the target (0,0). Management by Objectives Committees

The Funnel Experiment Rule 4: Move the funnel to the last position where the last marble hit. Rule 4 states that the funnel should be moved to the resting point, (xk,yk). Operator matches color from batch to batch without reference to original swatch. Operator attempts to make every piece like the last one. On the job training.
