ABSTRACT
The disciplines of maintaining quality all the time – process control monitoring. Safely sampling the stream of output. Risks in sampling, the risk window. Decision-making from a sound database, when to act and when not to act. Control chart construction and interpretation. Confidence limits and minimising the risks of being wrong. Predicting trouble and preventing it, husbanding resources. Taming the range. The dangers of numbering for numbering’s sake. The gallery of happy industrial landscapes which bring peace of mind.
