Advanced Quality Management / Six Sigma
Want World Class Quality? You need to ask for it by name. But getting the right Sigma-metrics requires more than just requiring Sigma-metrics in your tender or RFP. You need to specify more than just Sigma-metrics. You need to specify the goal, the level, the time period... well, we'll tell you how it can be done.
Are Sigma-metrics immune from manipulation? It should hardly be surprising that manufacturers will find ways to "boost" their Sigma-metric performance. A recent white paper provides an example of how manufacturers might mislead you - or make a mistake in their Sigma-metrics - and therefore alerts us to the safeguards we need to insist upon when we analyze performance data.
