Research into the use of statistical quality control in british manufacturing industry — part I

The work described in this paper is part of a large, Government‐funded investigation into the usage of statistical methods of quality control (SQC) in British manufacturing industry. This paper reports the results of an investigation of fifteen firms which claimed in earlier work to be successful users of SQC. It is shown that six of the companies were in fact not regularly using recognized SQC techniques. Some general conclusions are drawn from the activities of these, and the remaining nine companies which were examined in detail.
