The past efforts by the Aluminum Company of America (Alcoa) to create a statistically capable work force have met with limited success. Faced with a mixed record of translating statistical training to on-the-job application and meeting demanding executive expectations, members of the Alcoa Quality, Training and Education Department are creating tools which help Alcoa develop quantitatively literate employees- One result is a workshop which gives the participants hands-on experience and provides them with an appropriate set of statistical tools “just-in time”. This paper outlines the elements of the workshop, emphasizing that bringing a process into control and making it capable is really empirical learning. Learning models are explored, and an algorithm outlining a methodology to bring processes into control and make them capable is presented. 相似文献

In 1990s, with dramatic price reductions, reverse e-auctions were projected to be a widely used procurement tool. However, not all buyers saw the economic benefits of reverse e-auctions and the current usage is more limited than expected. This study identifies important organizational characteristics that determine the net return of e-auction programs and addresses why adopters of e-auctions experience varying profitability levels from their usage. The first step in the study concentrated on gathering interview and archival data from five large U.S. manufacturing firms that have used reverse e-auctions. Based on the field study findings, controlled experiments were conducted using a simulation model to assess identified influential factors for e-auctions. Implications for supply managers are presented and future research directions are discussed. 相似文献
