According to the Practicing Perfection Institute (PPI) survey, Six Sigma can improve human performance and workplace safety, slash errors and eliminate accidents, while showing efficiency improvements of more than 70%.
The results from three clients of PPI are:
- An electrical transmission organization in central Texas reports a 55.2% reduction in the average number of minutes per month of equipment outage caused by human error through integrating PPI’s methods.
- A major electrical transmission/distribution company in the northeastern U.S. reports that PPI’s own techniques for workplace safety resulted in an almost 75% reduction in human error rate — even in the midst of massive capital expansion employing multiple contractors!
- A commercial nuclear power plant was just awarded a Strength award by the World Association of Nuclear Operators (WANO) for its incorporation of Six Sigma methods.

So a company publishes positive results from three of its own customers and we’re going to call it a “survey” and imply that we can use this information to make general claims about the effectiveness of Six Sigma?
If we’re going to adopt a scientific viewpoint, perhaps we should apply it to thinly-veiled marketing claims as well…even when those claims support our own beliefs.
