A PCDA-Based Critical Exception Management System in Semiconductor Industry

After the global economic crisis, enterprises tend to lower their operating cost to improve their competitive advantages. Among different kinds of operating costs, lowering manufacturing cost brings the most significant effect. Among different manufacturing processes, not only the correctness and efficiency during producing products, but also those losses and expenses result from critical exception of product quality should be considered. The paper proposes a PDCA-based system for handling exception management process after critical exceptional events occurred. By facilitating managers to convene Material Review Board (MRB) meeting of critical exceptions, to manage and trace actions, and to constructing exception handling knowledge base, recurrence rate can be decreased after the efficiency of exception handling process is enhanced. Moreover, with completely recorded losses and costs, managers can manage enterprise resources in a more efficient way.
