Dr. Deming presented many seminars and some of those quotes are from those seminars
- as this one (and versions of it) are likely from.
From page 155 of Out of the Crisis
"Survival of the fittest. Who will survive? Companies that adopt constancy of purpose for quality, productivity, and service, and go about it with intelligence and perseverance, have a chance to survive. They must, of course, offer products and services that have a market. Charles Darwin’s law of survival of the fittest, and that the unfit do not survive, holds in free enterprise as well as in natural selection. It is a cruel law, unrelenting. Actually, the problem will solve itself. The only survivors will be companies with constancy of purpose for quality, productivity, and service."
