“A FIRST Guide to Quality Control for Engineers” (London: H. M. Stationery Office, 1945. Pp. 38. 1s. net), compiled in 1943 by Dr. E. H. Sealy of the Ministry of Supply Advisory Service on Quality Control for use by the Ministry of Supply when there was a great demand for a scientific method of controlling the quality of mass-produced goods, has now been released for general publication in the hope of assisting in the application of statistical methods to industry. It is intended primarily for use by engineers, and all examples are taken from actual engineering work. A method of plotting the standard control chart, of establishing control limits and of interpreting the significance of their relation to the drawing limits is detailed in the first two chapters, and a method of control specially adapted to suit multi-spindle automatic machines is described in a subsequent chapter. The handbook was used during the last two years of the War by the Ministry of Supply Advisory Service on Quality Control as a simple introduction to statistical methods for engineers who wish to begin using quality control in the machine shop and who have no prior statistical knowledge.
