Procedure WBD-HT81-C: White Bead Generation.

1.Required Tools: Paddle, for retrieval of beads.

2.Required Materials: Container with beads.

Process Steps1.Ensure paddle holes are empty of all beads.2.Grasp the paddle by the handle. Ensure that the holes are orientated facing upwards.3.Slide the paddle down into the beads until paddle is covered with beads. Pick up paddle to 4 inches above the bead level.4.Tilt paddle at a 47 degree angle to release excess beads.5.Withdraw paddle, ensuring that one bead is in each hole.6.Present to Quality Control for count of beads produced.7.Empty paddle back into bead container.

Rewarding or punishing the Willing Workers had no effect on the outcome. Extrinsic motivation is not effective.

People are not always the dominant source of variability.

Slogans, Exhortations and Posters Are At Best Useless To The Willing Worker.

People want to do a good job

Numerical goals and production standards can be meaningless. The number of red beads produced is determined by the process, not by the standard.

We can use statistics to create a quality control chart and look for problem areas and to predict future performance.

A faulty item is not a signal of "special" causes. A process can be stable, in-control and be producing 100 percent defective items. "Defects" are defined by specification, not by process.

Mean- Also called the average, a measurement of a center point in a data set.

Standard Deviation – A measurement of variation. Specifically a measure of how a set of data values fluctuate around the mean.

Upper/lower control limits – The highest/lowest value that can be expected to occur for a particular data set. 99.7300% of all results will fall between the upper and lower control limits.

It’s the system, not the workers alone that determine results

Rigid and precise procedures are not sufficient to produce the desired quality.

If you want to improve performance, you must work on the system.

Quality is made at the top. Quality is an outcome of the system. Top management owns the system.

Keeping the place open with only the "best" workers was acting on "superstitious" knowledge

Management was "tampering" with the system by rewarding and punishing the Willing Workers.

Management never looked in the box/Gemba

Thoughts from a Willing Worker named Ann. A Willing Worker named Ann, after the experiment on the Red Beads came to a close, expressed to Dr. Deming some provocative thoughts. She wrote her thoughts down in the following letter:

“When I was a Willing Worker on the Red Beads, I learned more than statistical theory. I knew that the system would not allow me to meet the goal, but I still felt that I could. I

wished to. I tried so hard. I felt responsibility: others depended on me. My logic and emotions conflicted, and I was frustrated. Logic said there was no way to succeed.

Emotion said that I could by trying. After it was over, I thought about my own work situation. How often are

people in a situation that they can not govern, but wish to do their best? And people do their best. And after a while, what happens to their drive, their care, and their desire?”

The Deming System of

Profound Knowledge

1.Appreciation of a system

2.Knowledge of variation

3.Theory of knowledge:

4.Knowledge of psychology

Once the individual understands the system of profound knowledge, he will apply its principles in every kind of relationship with other people. He will have a basis for judgment of his own decisions and for transformation of the organizations that he belongs to. The individual, once transformed, will:•Set an example•Be a good listener, but will not compromise•Continually teach other people•Help people to pull away from their current practices and beliefs and move into the new philosophy without a feeling of guilt about the past."
