Article Abstract

Current TQM and vendor certification programs are insufficient to create true supplier partnerships. Keki Bhote suggests an alternate method for achieving world-class vendor certification.Provide concrete help for vendors, via Design of Experiments (DOE) and Multiple Environment Over Stress Tests (MEOST), rather than remote, dictatorial control. Replace confrontation with vendor training and mutual specifications definition. Establish a steering committee to structure the supply process. Define commodity teams to audit suppliers' quality system. Track certification progress with pre-control, a technique more effective than control charts. Use Quality Function Deployment and DOE to develop specifications and discuss them with the supplier. Classify parameter and process characteristics into important and unimportant elements, highlighting the crucial tolerances and procedures. Use Positrol and Process Certification to control parameters. Incorporate reliability into specifications via MEOST, which compare product performance in a stress/time rectangle. Let Value Engineering use suppliers' knowledge of their product to place a dollar value on important elements. Employ cost targeting to reduce time spent in research. Apply financial incentives to increase suppliers' participation in quality improvement. Recognize the link between quality, cost, and cycle time.While certification itself is important, certification managed properly makes the difference between mediocre and world-class quality.
