"This paper outlines a management philosophy aimed at promoting employee involvement, quality and process improvement at Inco 's Thompson operations. It describes the use of statistical process control techniques, lessons learned and examples of progress.IntroductionThis paper provides an overview of the Manitoba Division's performance through the promotion of greater employee involvement, quality and process improvement. Having learned from other practitioners o f quality management, the Manitoba Division believes its experiences are applicable to all mining and other businesses.The Thompson operation consists of two underground mines, an open pit, a mill, a smelter and an electrolytic refinery. The workforce consists of 2000 members. The main products are electrolytic nickel slab and proprietary nickel rounds. Production levels are currently at capacity in response to heavy market demand.Paralleling much of the mining industry the corporation was faced with six years of decreasing nickel prices (Fig. I). Inco Limited survived by focusing on productivity and cost improvement. Manitoba Division productivity improved 32070 over three years beginning in 1982-the worst financial year in the company's history (Fig. 2). A real unit cost reduction of 20%, net of inflation, was also achieved (Fig . 3)."
