Analysis of the effect of planning/design phase factors on rework

Thesis (S.M.)--Massachusetts Institute of Technology, Engineering Systems Division; and, (M.B.A.) -- Massachusetts Institute of Technology, Sloan School of Management; in conjunction with the Leaders for Manufacturing Program at MIT, 2008.Includes bibliographical references (p. 59-60).Over the past several years, Raytheon has experienced great growth in their revenue and sales. One of the contributing organizations to that growth has been the Space and Airborne Systems (SAS) business sector. To continue this growth, SAS has started initiatives to improve their Operations. One of these initiatives is to reduce the amount of rework performed within the manufacturing centers. By reducing rework, SAS will be able to reduce costs, meet aggressive schedules, and continue to satisfy customer's needs. This paper describes the development of two tools to reduce rework in an attempt to meet Raytheon's goals. One is a manufacturing/Earned-Value Measurement System monitoring tool. The second tool determines the factors during the design and planning phases of a project that affect rework. Developing these two tools will help increase transparency on the manufacturing shop floor and help reduce the amount of rework performed.by Michael W. Liu.M.B.A.S.M
