A study of statistical process control: Practice, problems and training needs

To ascertain factors relevant to effective training for statistical process control (SPC), this study examines the training practices and needs of 10 UK manufacturing organizations of different sizes and product ranges. In the companies, which were all actively using SPC, major training needs mere found over the whole range of SPC-related activities, from conceptual understanding of its potential effectiveness as a quality, tool, through the development of diagnostic and problem-solving? skills, down to basic control chart completion and interpretation. The companies that seemed most effective in the use of SPC had devolved more SPC procedures to employees lower in the organizational hierarchy. In those companies, all employees had good levels of education and the training tended to focus on domain-relevant and conceptually concrete approaches. In the other companies, a diverse mixture of forms of training were used, with limited success. From the training needs identified and the comparison of the forms of training, some recommendations for the design of SPC training have been inferred.
