  1. Lecture #2 - EME6403 - QC Brief Review of QS9000 and Chapter 1 of Montgomery

  2. QS 9000 • Automotive Adaptation of ISO9000 • ISO9000 initially written in 1987 • Adopted by over 60 countries • ‘Quality management and quality assurance standards - provides guidelines for the selection and use of the standard’ • To prove you adhere - REGISTRATION!!

  3. QS9000 • Consists of 20 elements of ISO9000 • Divides up the business process • ‘management, quality, contracts, design, document and data control, purchasing, inspection and testing, inspection and test status, control of customer supplied product, prod. ID and traceabilikty, process control, conyrol of inspection/measuring/test equipment, control of nonconforming product, corrective and preventative action, handling, quality records, internal quality audits, training, servicing, statistical techniques

  4. THREE unique Automotive adaptations • Production part approval process • PPAP • Continuous improvement • Manufacturing capabilities

  5. Other versions of 900X • 9001 - Service Organization • 9002 - production and installation • 9003 - inspection and testing • 9004 - Management

  6. What to do?? • Say what you do and do what you say • First of all: DOCUMENT what you do • Second of all: Make sure documentation proves this • External auditors enforce • *read up* on documentation • the document is hefty

  7. The Big Three Document • In order to simplify life and coordinate things, the copied QS9000 document takes each of the 23 elements and explains its documentation further • *quickly review* the document to get a feel for the documentation required by this process

  8. Your homework • You may or may not have been in a QS9000 completed process • In either case, select one element of your job and figure out where it fits [ie. 4.19] • Create a one page item that either: • states what you do and what documents are required to prove this • is the proposed document to follow

  9. Caveats • Typically, the process takes 6-12 months • Your homework should not exceed an hour • Simply document one aspect of your job, or create a document to document your job • If you have already done this and it is in a 3 ring binder …. • Adapt it or do it fresh

  10. CHAPTER 1 - Strategy of Experimentation • A problem is assumed - and inquiring minds want to find out more details • What factors have an influence on this problem • If a factor has an effect, what should we do about it? • How can we do this FAST and CHEAP!

  11. Define Experiment • Your process has a problem • The ‘Experiment’ is the process of intelligently collecting data regarding the problem and cleverly analyzing it • There will be controllable and uncontrollable factors - shades of grey • There are inputs and outputs to the process

  12. Example - Emissions test engineer • the factors that could impact your test results: • type of car • type of catalytic convertor • temp/humidity/etc • operator

  13. Basic Principles • Statistical design of experiment - plan the experiment so your data collected will be cleverly analyzed • Two aspects: • clever planning [Design] • clever implementation

  14. Guidelines for statistical experimentation • Recognition and statement of the problem • Choice of factors, levels, ranges • process knowledge • Selection of response variable [ $$$] • Actual design selection • implementation • analysis • conclusion and results

  15. conclusion - Keep in mind: • use non-statistical knowledge • KISS • recognize the difference between practical and statistical significance • Experiments are INTERATIVE!!! • SECOND HOMEWORK: RULE 1: • Eyeball some statistics from Chapter 2
