W. Edwards Deming Quotes

Quote by W. Edwards Deming

There are four prongs of quality and four ways to improve quality of product and service:

Innovation in product and service
Innovation in process
Improvement of existing product and service
Improvement of existing process

The common mistake is the supposition that quality is ensured by No. 4, improvement of process, that operations going off without blemish on the factory floor, in the bank, in the hotel will ensure quality. Good operations are essential, yet they do not ensure quality. Quality is made in the boardroom.

A bank that failed last week may have had excellent operations— speed at the tellers’ windows with few mistakes; few mistakes in bank statements; likewise in the calculation of interest and of penalties and loans. The cause of failure at the bank was bad management, not operations.
