Red bead game for better understanding Deming

The RED BEAD Experiment is a tool that allows workers and managers and customers to unite using a common language to find ways to treat each other with respect; get beyond the old biases and to work as a team.


The result will be to find the red bead problems that are the causes of their: rework; the wasted effort; and the changes in mind that take away our profit; our worker satisfaction and push good customers away to look for another supplier!

Deming’s Seven Deadly Diseases of Management

Video from Deming’s voice can be seen: 

While the 14 Points for Management can be said to express Dr. Deming’s philosophy of transformational management, his Seven Deadly Diseases of Management describe the most serious barriers that management faces to improving effectiveness and continual improvement. The video discusses in detail the first Five Deadly Diseases. He did not include in the video number Six and Seven which he said in “Out of the Crisis” were, “Peculiar to industry in the U.S., and beyond the scope of this book.”

1. Lack of constancy of purpose to plan product and service that will have a market and keep the company in business, and provide jobs.

2. Emphasis on short-term profits: short-term thinking (just the opposite from constancy of purpose to stay in business), fed by fear of unfriendly takeover, and by push from bankers and owners for dividends.

3. Evaluation of performance, merit rating, or annual review.

4. Mobility of management; job hopping.

5. Management by use only of visible figures, with little or no consideration of figures that are unknown or unknowable.

6. Excessive medical costs.

7. Excessive costs of liability, swelled by lawyers that work on contingency fees.

Two books: Deming and American Physician in Turkey


I’ll share the books I liked here. I hope that will contribute my reading effort and be beneficial for my virtual library. Nowadays I read that book. Mary Walton had written book after her observations and interviews. Taking support from that type of books for better understanding of quality philosophy is vital. 

… And other book I explored today was THIS one. An American Physician in Turkey. It is a free google book. A doctor who practices medicine in Turkey in World War years. It’ll be a quite good opportunity to read medical history from an American’s point of view.
