The Final Manufacturing Group (FMG) at Motorola, Inc.'s Semiconductor operations in Phoenix, AZ, recognized the need for new quality measures to bring a supplier's quality performance to zero defects. FMG now uses process analysis techniques to improve supplier quality. They have progressed from a basic compliance audit to the Supplier Manufacturing Effectiveness Survey, which provides more information to FMG as well as to the client.The steps in performing a process analysis study (audit) are the same as in a traditional quality audit: initiation, planning, implementation, reporting, and follow-up. However, unlike the traditional quality audit in which auditors are independent and do not offer any recommendations or corrective actions, the process analysis study encourages the auditor or audit team to be involved in the problem solving efforts. This audit requires a sound customer-supplier partnership and emphasizes problem solving to improve quality.The process analysis study is an excellent tool for enhancing audit procedures and for reducing defect levels in a supplier who is already practicing good quality methods. During a three-month time period, the defect level of one problem area was reduced from 330 ppm to 30 ppm. An added benefit is the enhancement of the customer/supplier relationship.
