3 1. Introduction it is the purpose of advanced quality management to prevent that unreliable designs or processes are used in serial production therefore it is necessary to have one extensive, strict approval process for new or changed designs or processes inevitably this process causes some administration work but its worth while because it reduces the production of muda! Seite 5 Saving by taking advantage of the Rule Of The 10 : The cost of the remedy of a defect increases tenfold with every step, the project advances! Early identification of a defect EXPENSES...saves the major part of the cost! PROJECT TIME Seite 6

4 Savings by avoiding the 7+1 muda errors over production stock muda in the process muda unnecessary movement unnecessary transport waiting time Design ignoring the customer s expectations Seite 7 Too high stocks... take space raise assets employed require additional searching require additional administration require additional transport are a risk, because parts might exceed expiration date or become unsaleable are a risk, because parts might be damaged complicate the overview are often a consequence of a weak process cover weak process Seite 8

5 Requirement for low stocks... are controlled and capable processes and Total Productive Maintenance since all kind of process problems will cause delivery stops, if the stocks are low! lower stocks Seite 9 Advantages of controlled & capable production processes satisfied customers by good quality and avoided muda no scrap, no rework constant flow of material low stocks possible Seite 10

Customer Notification The organization shall notify the authorized customer representative of any planned changes to the design, process or site. Examples are indicated in Table 3.1 Notification of all changes to desing nad process is the the organization s resonsibility. Upon notification and approval of the proposed change by the authorized customer representative, and after change implementation, submission is required unless otherwise specified 2. Submission to Customer The organization shall submit for approval prior to the first production shipment in the following situations (see Table I.3.2) unless the authorized customer representative has waived this requirement. The organization shall review and update all applicable items in the file to reflect the production process, regardless of whether or not the customer requests a formal submission. The file shall contain the name of the authorized customer representative granting the waiver and the date Seite 27 Table 3.1: Customer Notification Required 1. use of other construction or material than was used in the previously approved part or product 2. production from new or modified tools (except perishable tools), dies, molds, patterns, etc., including additional or replacement tooling 3. production following refurbishment or rearrangement of existing tooling or equipment 4. production from tooling and equipment transferred to a different plant location or from a additional plant location. 5. change of subcontractor for parts, non-equivalent materials or services (e.g.: heat-treating, plating) that affect customer fit, form, function, durability, or performance requirements 6. product produced after tooling has been inactive for volume production for twelve months or more 7. product and process changes that impact fit, form, function, performance, and/or durability of the salable product Seite 28

16 2.4. Submission Levels Note: The content of the documentation to be generated is always the same! The supplier has to retain everything (e.g.. as a copy)! the Submission Level just indicates what has to be submitted to the customer! Seite 31 There are five Submission Levels: 1. warrant only (and if applicable an Appearance Approval Report) 2. warrant with product samples and limited supporting data 3. warrant with product samples and complete supporting data 4. warrant with other requirements as defined by the customer 5. warrant with product samples and complete supporting data available for review at the organization s manufacturing location Seite 32

17 The customer decides about the submission level I want I need I wish...looking at: the status of the supplier (Ford Q1,...) his experience with earlier approval processes the know-how of the supplier concerning this product the importance of the part so the submission level might be different for every product Seite 33 S = submit retain a copy at an appropriate location, (including manufacturing) R = retain at appropriate locations (including manufacturing) has to be made readily available to the customer representative upon request * = retain at appropriate locations submit upon request Seite 34

18 LEVEL 3 IS THE STANDARD LEVEL" IT SHALL BE USED FOR ALL SUBMISSIONS UNLESS SPECIFIED OTHERWISE BY THE RESPONSIPLE CUSTOMER PRODUCT APPROVAL ACTIVITY Level 1 = just warrant and (if applicable) Appearance Approval Report Level 2 = standard minus process description and background information Level 3 = standard Level 4 = warrant, other requirements as defined by the customer Level 5 = the complete list, and everything will be checked at the supplier s site!

19 After everything is ready, it will be submitted to the customer! namely at the responsible product approval activity the customer will inspect everything and notify the organization of the result using the Part Submission Status Seite 37 Part Submission Status ORGANIZATIONS MAY NEVER SHIP PRODUCTION QUANTITIES BEFORE CUSTOMER APPROVAL! Upon approval of the submission, the organization shall assure that future production continues to meet all customer requirements For those organizations that have been classified as self-certifying by a specific customer ( Submission Level 1), submission of the required organization-approved documentation will be considered as customer approval unless the organization is advised otherwise Seite 38

20 Part Submission Status: A B C Approved Interim Approval Rejected Seite 39 Part Submission Status A = Approved indicates that the part or material meets all customer specifications and requirements the organization therefore is authorized to ship production quantities of the product subject to releases from the customer scheduling activity Seite 40

21 Part Submission Status B = Interim Approval Permits shipment of material for production requirements on a limited time or piece quantity basis. Interim Approval will only be granted when the organization has: clearly defined the non-compliances preventing approval; and, prepared an interim approval action plan agreed upon by the customer The organization is responsible for implementing containment actions to ensure that only acceptable material is beeing shipped to the customer. re-submission is required to obtain a status of Approved material covered by an interim approval that fails to meet the agreed-upon action plan either by the expiration date or the shipment of the authorized quantity will be rejected. No additional shipments are authorized unless an extention of the interim approval is granted Seite 41 Part Submission Status C = Rejected Means that the submission does not meet the customer requirements, based on the production lot from which it was taken, and/or accompanying documentation In such cases, the submission and/or process (as appropriate) shall be corrected to meet the customer requirements. The submission shall be approved before production quantities may be shipped Seite 42

35 Seite Initial Process Studies General Quality Indices Acceptance Criteria for Initial Study Unstable Processes Processes With One-Sided Specifications or Non-Normal Distributions Actions To Be Taken When Acceptance Criteria Are Not Satisfied Seite 70

36 General the level of initial process capability or performance shall be determined to be acceptable prior to submission for all special characteristics designated by the customer or the organization (sc,cc) the organization shall perform measurement analysis to understand how measurement error is affecting the study measurements (see Measurement System Analysis reference manual) for explanations about Cpk or Ppk see SPC (Statistical Process Control manual) Seite 71 Mean Value x Turning Point Standard Deviation s Gauß Normal Distribution Seite 72

37 Definitions Process under Control / Capable Process not capable capable under control not under control Seite 73 The Capable Process Example Process Capability Index Comment C p = Process Capability Index Shows proportion of the permissible tolerance interval to the scatter Scatter is measured in multiples of the standard deviation s If the scatter is with +/- 3 s within the tolerance, then C p =1 C pk = Critical Process Capability Index Supplementary considers the mean of the process not being equal to the middle of the tolerance interval Example 1 to 3 No capability High amount of scrap No capability If centered pretty exact, just about no scrap Very good capability Statistically no scrap No capability Not centered Scrap Good capability Process is centered enough Little scrap Process adjusted exactly to center of tolerance interval Seite 74

38 Quality Indices Initial process studies shall be summarized with capability or performance indices, if applicable. NOTE 1: The initial process study results are dependent on the purpose of the study, method of data acquisition, sampling, amount of data, demonstration of statistical control. etc. See the QS-9000 Statistical Process Control reference manual for additional information in understanding the basic principles of statistical stability and process measures (indices). For guidance on items listed below, contact the authorized customer representative Seite 75 C pk and P pk C pk - The capability Index for a stable process. The estimate of sigma is based on within subgroup variation. C pk is an indicator of process capability based on process variation within each subgroup of a set of data. C pk does not include the effect of process variability between the subgroups. C pk is an indicator of how good a process could be if all process variation between subgroups was to be eliminated. Therefore, use of C pk alone may be an incomplete indicator of process performance. P pk - The performance index. The estimate of sigma is based on total variation (all of individual sample data using the standard deviation. P pk is an indicator of process performance based on process variation throughout the full Set of data. Unlike C pk, P pk is not limited to the variation within subgroups. However, P pk cannot isolate within subgroup variation from between subgroup variation. When calculated from the same data set, C pk and P pk can be compared to analyze the sources of process variation. For more information, see QS-9000 Statistical Process Control Seite 76

39 Purpose of Initial Process Studies The purpose of the initial process study is to understand the process variation, not just to achieve a specific index value. When historical data are available or enough initial data exist to plot a control chart (at least 100 individual sarnples), Cpk can be calculated when the process is stable. Otherwise, for processes with known and predictable special causes and output meeting specifications, Ppk should be used. When not enough data are available (< 100 samples) or there are unknown sources of variation, contact the authorized customer representative to develop a suitable plan Seite 77 Examination of the stability (Process control) process seems stable process seems instable examine capability continue with Process may not meet customer requirements continue with Seite 78

40 Acceptance Criteria for Initial Study Capability Index for stable process Index > Index 1.67 Index < 1.33 the process currently meets the acceptance criteria after approval, begin production and follow control plan the process may be acceptable contact the authorized customer representative for a review of the study results the process does not currently meet the acceptance criteria contact the authorized customer representative for a review of the study results Seite Unstable Processes Depending on the nature of the instability, an unstable process may not meet customer requirements. The organization shall identify, evaluate and, wherever possible, eliminate special causes of variation prior to submission. The organization shall notify the authorized customer representative of any unstable processes that exist and shall submit a corrective action plan to the customer prior to any submission. NOTE: For bulk materials, for processes with known and predictable special causes and output meeting specifications, corrective action plans may not be required by the customer Seite 80

41 Processes With One-Sided Specifications or Non-Normal Distributions The organization shall determine with the authorized customer representative alternative acceptance criteria for processes with one-sided specifications or nonenormal distributions. NOTE: The above mentioned acceptance criteria assume normality and a two-sided specification (target in the center). When this is not true, using this analysis may result in unreliable information. These alternate acceptance criteria could require a different type of index or some method of transformation of the data. The focus should be on understanding the reasons for the nonnormality (e.g., is it stable over time?) and managing variation. Refer to the Statistical Process Control reference manual for further guidance Seite Actions To Be Taken When Acceptance Criteria Are Not Satisfied The organization shall contact the authorized customer representative if the acceptance criteria cannot be attained by the required submission date. The organization shall submit to the authorized customer representative for approval a corrective action plan and a modified Control Plan normally providing for 100% inspection. Variation reduction efforts shall continue until the acceptance criteria are met, or until customer approval is received. NOTE: 100% inspection methodologies are subject to review and concurrence by the customer Seite 82

42 4.12 Qualified Laboratory Documentation Inspection and testing for shall be performed by a qualified laboratory as defined by customer requirements (e.g., an accredited laboratory). The qualified laboratory (internal or external to the organization) shall have a laboratory scope and documentation showing that the laboratory is qualified for the type of measurements or tests conducted. When an external/commercial laboratory is used, the organization shall submit the test results on the laboratory letterhead or the normal laboratory report format. The name of the laboratory that performed the tests, the date (s) of the tests, and the standards used to run the tests shall be identified Seite Appearance Approval Report (AAR) AAR = approval report for the appearance of appearance items concerning requirements on color, structure, or surface For completion of AAR, see instruction in, appendix B A separate AAR shall be completed for each part or series of parts for which a submission is required if the product/part has appearance requirements on the design record Upon satisfactory completion of all required criteria, the supplier shall record the information on the AAR since the Appearance Approval Report is a industry wide used form not all customers will require entries in every position Seite 84

43 4.13 Appearance Approval Report (AAR) / The completed AAR and representative production products/parts shall be submitted to the location specified by your customer to receive disposition AARs (complete with part disposition and customer signature) shall then accompany the PSW at the time of final submission based upon the submission level requested Seite Seite 86

44 4.14 Sample Production Parts The organization shall provide sample products as specified by the customer Seite Master Sample The organization shall retain a master sample for the same period as the production part approval records, or a) until a new master sample is produced for the same customer part number for customer approval, or b) where a master sample is required by the design record, Control Plan or inspection criteria. as a reference or standard. The master sample shall be identified as such, and shall show the customer approval date on the sample. The organization shall retain a master sample for each position of a multiple cavity die, mold, tool or pattern, or production process unless otherwise specified by the customer Seite 88

45 4.16 Checking Aids If requested by the customer, the organization shall submit with the submission any part-specific assembly or component checking aid. The organization shall certify that all aspects of the checking aid agree with part dimensional requirements. The organization shall document all released engineering design changes that have been incorporated in the checking aid at the time of submission. The organization shall provide for preventive maintenance of any checking aids for the life of the part. measurement system analysis studies, e.g. gage R&R, accuracy, bias, linearity, stability studies, shall be conducted in compliance with the customer requirements. See MSA (Measurement Systems Analysis reference manual) Seite Customer-Specific Requirements The organization shall have records of compliance to all applicable customer-specific requirements. For bulk materials, applicable customer-specific requi rements shall be documented on the Bulk Material Requirements Checklist Seite 90

46 4.18. Production Part Submission Warrant Upon completion of all requirements, the organization shall complete the Part Submission Warrant (PSW). Warrant A separate PSW shall be completed for each customer part number unless otherwise agreed to by the authorized customer representative. If production parts will be produced from more than one cavity, mold, tool, die, pattern, or production process. e.g., line or cell, the organization shall complete a dimensional evaluation on one part from each. The specific cavities, molds, line, etc., shall then be identified in the Mold/Cavity/Production Process line on a PSW, or in a PSW attachment Seite Production Part Submission Warrant/ The organization shall verify that all of the measurement and test results show conformance with customer requirements and that all Warrant required documentation is available and, for Level 2, 3, and 4, is included in the submission as appropriate. A responsible official of the organization shall approve the PSW and provide contact information Seite 92

47 Part Submission Warrant consists of: Information about the part Some formal information Materials reporting Reason of the submission Requested submission level Result of the submission Declaration For customer use (result) Seite 93 Detail of Part Submission Warrant Seite 94

48 Dimension Results / Part Weight (Mass) The organization shall record on the PSW the part weight of the part as shipped, measured and expressed in kilograms to four decimal places (0.0000) unless otherwise specified by the customer. The weight shall not include shipping protectors, assembly aides, or packaging materials. To determine part weight, the organization shall individually weigh ten randomly selected parts, calculate and report the average weight. At least one part shall be measured from each cavity, tool, line or process to be used in product realization. NOTE: This weight is used for vehicle weight analysis only and does not affect the approval process. Where there is no production or service requirement for at least ten parts, the organization should use the required number for calculation of the average part weight Seite 95 Contents 1.

49 The Attempt to Run without APQP! Seite 97 The Production Part Approval Process is an extensive strict approval process for new or changed designs or processes. Summary It is very formalized, so it inevitably causes some administration work, but it doesn t demand anything that makes no sense from an engineer s point of view! Later changes of the product or the process are expensive and take a lot of time. The prerequisite to fulfill demands is a carefully done quality planning according to QS-9000 APQP Seite 98
