Quality Basics Conformance Quality How it performs versus design (or versus expectation). Producers measure it during manufacturing Testing all functions work. Testing durability of parts. Testing that it works correctly for thousands of cycles. https://www.gettyimages.com/detail/news-photo/sunbeam-toasters-sitting-on-assembly-line-news-photo/50628361#/sunbeam-toasters-sitting-on-assembly-line-picture-id50628361
Quality Basics Conformance Quality Consumers also experience it. Expectations and warranties. “dies” Expected/Designed duration 3. Quality conformance? Years of use 1 2 3 4 5 6 7 “dies” Expected/Designed duration: 10. Quality conformance?
Quality Measurement Manufacturing processes include steps to verify conformance to specifications = good quality. Repetitive tests (number of successes before it breaks down) special equipment test often damages the product being tested, so only performed in a sample Functional test (Dishwasher turns on, all cycles work, water does not leak) Aesthetics are also inspected
Quality Measurement Is it necessary to inspect 100% of what is produced? Should we just take a sample? Factors: Probability of defects Cost / time to inspect Effect of inspection on product Cost/effect of the defect 100% inspection is no guarantee 0 defects. Multiple sample techniques and models based on desired confidence level
