10、ive Action and Disposition System for Nonconforming Material REQUIREMENTS Corrective Action and Disposition System: The Quality System shall provide for analysis of scrap, rework, and repair costs. Results of analysis shall be used to evaluate methods to reduce these costs. Evidence of cost reductio

11、ns shall be available. Corrective action documentation shall be maintained and positive action shall be taken to identify and reduce costs associated with nonconforming materials. Statistical Process Control (SPC): There shall be provisions for ensuring that when process control techniques are appro

12、priate, that control limits are established statistically or by other agreed upon methods. Control limits shall be based on the documented history of the process capability. Control Limit Standards There shall be provisions for developing and recommending to the customer the use of standards applica

15、ated by collective analyses, trend reviews, or other acceptable means. Quality Improvement: The supplier shall have a documented quality improvement program throughout his organization The supplier shall assign organization elements, teams, or individuals to investigate technology, methods, and proc

16、edures to increase efficiency and conformance to requirements. The supplier Corrective Action Board (CAB) or other group senior to the CAB shall monitor the QIP for progress towards established goals at regular intervals. Contractors Written Procedures: The requirements for full MRB shall be impleme

17、nted through the preparation, publication, and maintenance of detailed written procedures. Material Review Board (MRB): The supplier MRB shall be chaired by a supplier appointed representative, and the MRB shall include personnel representing other supplier organizations necessary to determine the d

18、isposition of nonconformances. The supplier shall maintain a current list showing qualified MRB members including a representative of the Engineering Organization responsible for product design. MRB members shall be selected on the basis of their documented technical competence. The supplier MRB sha

19、ll investigate in a timely manner all nonconforming material that has not been dispositioned by preliminary review. Supplier MRB dispositions shall be made available to the govemmentkustomer when required by contract. Copyright SAE International Provided by IHS under license with SAENot for ResaleNo

21、to identify causes of nonconformances and cany out required corrective actions. The supplier CAB shall maintain records of cases, trends, and individual causes it acted upon and prepare summaries of actions taken. The CAB shall have the authority to: a. b. C. d. e. f. 9. h. 1. Ensure that an effecti

22、ve corrective action system is functioning throughout the organization. Require investigations and studies by other organizations necessary to define essential corrective actions which will result in reducing the number and cost of nonconformances. Ensure maintenance of applicable documentation. Ens

23、ure that summary data of nonconformances and associated costs are analyzed and areas of high potential payoff, adverse trends, exceeding control limits, or out-of- control recurrence of nonconformances are thoroughly investigated to identify appropriate corrective actions and to identify potential Q

24、IPs. Ensure the adequacy of follow-up systems. Ensure that reviews of nonconformance data and PR and MRB disposition decisions are conducted periodically to determine that PR and MRB (if authorized) actions are effective and in compliance with applicable standards. Ensure that process evaluation is

25、accomplished and that specific corrective actions are taken when indicated by control limit techniques and analysis of cumulative data. Ensure that nonconformances are documented and that the processes are monitored until effectiveness of corrective action is demonstrated. Initiate and monitor QlPs
