Quality and The Art of Discovery by Professor George Box (1990):
Quotes by George Box in the video:
“I think of statistical methods as the use of science to make sense of numbers”
“The scientific method is how we increase the rate at which we find things out.”
“I think the quality revolution is nothing more, or less, than the dramatic expansion of the of scientific problem solving using informed observation and directed experimentation to find out more about the process, the product and the customer.”
“It really amounts to this, if you know more about what it is you are doing then you can do it better and you can do it cheaper.”
“We are talking about involving the whole workforce in the use of the scientific method and retraining our engineers and scientists in a more efficient way to run experiments.”
“Tapping into resources:
- Every operating system generates information that can be used to improve it.
- Everyone has creativity.
- Designed experiments can greatly increase the efficiency of experimentation.
An informed observer and directed experimentation are necessary for the scientific method to be applied. He notes that the control chart is used to notify an informed observer to explain what is special about the conditions when a result falls outside the control limits. When the chart indicates a special cause is likely present (something not part of the normal system) an informed observer should think about what special cause could lead to the result that was measured. And it is important this is done quickly as the ability of the knowledgable observer to determine what is special is much greater the closer in time to the result was created.
