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

• 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

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.

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.

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 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).

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).
