Webinar Recordings:  Six Sigma: the Good, the Bad, the Ugly and the Better, Sept 16, 2020

Most laboratories either use, plan to use, or think they should use six sigma to evaluate method performance, select QC rules and troubleshoot. Yet there are significant disagreements on what sigma means, how to calculate it, and what is acceptable.  At this webinar, we explore the true meaning and common misconceptions of six sigma – and the other definition of insanity: “everyone doing something differently and expecting the same result!”.

The one hour webinar is divided here into three segments as a courtesy to busy viewers.

Part 1:  Calculations Matter

Part 1 introduces:
What does six sigma mean?
Calculations matter!

 Poll results of how people perceive, calculate and use sigma
There are 2 popular meanings of six sigma (One is right)
Labs use 4 different formulae to calculate sigma (One is right)
Different labs use different standards for acceptable sigma levels – with over 10,000x difference in number and cost of errors/year

Part 2:  Numbers Cost and Insanity

This section deals with
The myth of the 1.5 sigma shift;
Definitions of insanity and Assigning cost to error.
Poll results of how people perceive, calculate and use sigma

Labs use sigma to select QC rules, evaluate method performance and guide troubleshooting – with different calculated values and standards

A 3-sigma method is equally perceived to produce 1,350 or >66,000 errors/year




Part 3:  A Better Way!
