South Dakota School of Mines & Technology Deming’s Funnel Exp. Industrial Engineering

Funnel Experiment u 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 1: (LTDTA) Set the funnel over the target at (0,0) and leave the funnel fixed through all 50 drops. Funnel Experiment; Rule Xk Yk

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 (-x k,-y k ) from its last resting point. Funnel Experiment; Rule Xk Yk

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 (-x k,-y k ) from its last resting point. Machine/Process adjustment rules using control chart limits. Automatic compensating machinery

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 (-x k,-y k ) from the target (0,0). Funnel Experiment; Rule Xk Yk

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 (-x k,-y k ) 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, (x k,y k ). Funnel Experiment; Rule Xk Yk

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, (x k,y k ). 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.
