Deming gave the tools for management to use knowledge of variation to accomplish just that. This doesn't entail that Dr. Deming was against variation because he advocated attempts to discover (and eliminate) unique sources of variation and aimed to regulate common reason variation (to attain the "correct uniformity") that led to inefficient operations and damage to customers. It also doesn't imply that he didn't comprehend the value of diversity in situations other than the one in which it created issues.
