10、tion No. 146A -i- GUIDELINES FOR SUPPLIER PERFORMANCE RATING Introduction Manufacturing operations often require the use of suppliers and subcontractors for materials, piece parts, manufacturing, test, and finish operations. Semiconductor suppliers are using semiconductor fabrication, package assemb

11、ly, test, and finish subcontractors. Users of semiconductor products are relying on PCB (Printed Circuit Board) fabrication subcontractors and PCB assembly subcontractors for these operations as well as reliance on distributors of electronic components for inventory management and stock room functio

12、ns. With the increasing reliance on second or third parties to assist in the manufacture of goods, there exists a need to measure and rate suppliers based on consistent criteria that can be measured. There is also a need for suppliers to be measured uniformly by their customer base so that suppliers

13、 who market to a broad base of customers can understand the data presented and translate that understanding into meaningful preventive or corrective actions. This document provides a vehicle to accomplish the task of measuring suppliers in a consistent manner. JEDEC Publication No. 146A -ii- JEDEC P

14、ublication No. 146A Page 1 GUIDELINES FOR SUPPLIER PERFORMANCE RATING (From JEDEC Board Ballot JCB-08-59, formulated under the cognizance of the JC-14.4 Subcommittee on Quality Processes and Methods.) 1 Scope The intent of this document is to establish guidelines and provide examples by which custom

15、ers can measure their suppliers based on mutually agreed upon objective criteria. These results can then be used to improve communications between customers and suppliers. The document applies to supplier / customer interfaces. Subcontractors used by suppliers are not addressed separately but are in

16、cluded in the rating of the supplier. 2 Reference Documents ISO 9000 3 Terms and definitions corrective action request: A formal request from a customer to a supplier requiring an investigation into the root cause of a specific problem and the steps taken to prevent recurrence. delivery and lead tim

19、tions (contd) supplier performance rating: An assessment of the metrics established to evaluate a suppliers performance. supplier report card: A document that conveys to a supplier an evaluation of their performance based on criteria as defined by the customer and agreed to by the supplier. NOTE The

20、 report should contain the rating for each item. technology rating: An assessment of the metrics established to evaluate technology attributes. 4 Measurements of Supplier Performance Customers should maintain performance metrics for at least their key suppliers. Items such as quality, reliability, d

21、elivery, technology, and value should be measured. It is recommended that the supplier be included in the discussions on what to measure and how the measurement will be accomplished and reported. JEDEC Publication No. 146A Page 3 5 Procedure a) A rating system should be established that will rank an

22、d differentiate suppliers. All metrics defined may apply to all suppliers rated and ranked together. Metrics should be quantitatively determined and agreed to between supplier and customer. b) A supplier report card should be generated on an agreed upon schedule. It is recommended that this report s

23、hould be issued quarterly. Annex A shows an example of an approach to a supplier report card. c) The customer should assume responsibility for the following: 1) Engage the supplier in meaningful dialogue to set expectations and obtain supplier agreement; 2) Maintain records of the supplier report ca

24、rd; 3) Present and explain the supplier report card to the supplier on an agreed schedule; 4) Discuss each metric in the supplier rating system that falls below expectations with the supplier; 5) Document agreed upon preventative or corrective actions; 6) Issue formal supplier corrective action requ

25、ests (SCAR) if warranted or applicable. It is recommended that such a request accompany the supplier report card in the event the information is mailed to a supplier; 7) Customers should determine the relative importance of each item in the areas of quality, delivery, technology, value, and service

26、if using annex A; 8) Customers should group suppliers into meaningful categories for comparison purposes. For example: Suppliers of memory product compared to other memory suppliers. d) The supplier should assume the following responsibilities: 1) Discuss expectations with the customer. 2) Review an

27、d maintain records of the supplier report card 3) Utilize the feedback of the supplier report card as part of the management review process. 4) Highlight any inaccuracies or concerns with the supplier report card to the customer in a timely manner. 5) Document and communicate to the customer any pre

In case of qualitative assessment choose rating table at the bottom of the template. 4) Calculate weighted mean rating value per main item 5)

30、 Calculate weighted mean rating value (Totals) Explanation of headers in the rating tables: 1) Description of sub criteria contributing to performance 2) Measure to be used for measuring the performance (column gives some suggestions) 3) Weight of the sub criteria within the main item 4) Value of th
