Six Sigma Test Process: Lower Failure Rate ...
Six Sigma process is used in test process to lower failure rate at disk drive maker. Chris Mellor explores disk drive companies and the successes and failures in the marketplace. ...
Six Sigma Test Process: Lower Failure Rate: Via ARNnet | All is not quiet on the Western Digital front
Additional resources on using Six Sigma in the test process:
Via Westgard QC Lesson: From Method Validation to Six Sigma - Translating Method Performance Claims into Sigma Metrics: "While it is probably disconcerting to find that a single test process has two different Sigma metrics, it's not surprising that a test performs differently at different levels. It would be far more unusual if a test performed the same at all the levels of concentration. For the high level control, a Sigma metric of 4.56 is actually acceptable. But for the low level control, a Sigma metric of less than zero is clearly bad. "
Via Conference Presentation Summary: "Running these tests by hand became cumbersome so the group developed a nightly test harness that runs each of the quality tests and collects all of the data to present a single comprehensive view of measured quality. It was a small move from this point to start a continuous test process that runs a slimmed down set of the quality tests whenever code is checked into the source code repository. The continuous measure of quality then is the final blending of extreme programming with Six Sigma. "
Software Verification and Validation Consulting - Best Practices - Via Wipro Technologies: "This model supports the improvement of test processes, offers insight into maturity of test processes, defines new test strategy and recommends immediate improvement steps. "
... "There have been design improvements, an extended test process to reduce infant mortality and improve the product (so as) to lower the failure rate. Some Raptor mechanisms are re-used. The extended test process is all part of a Six Sigma process, a manufacturing quality discipline which Seagate also uses. " ...
