Here is another of those articles that promotes the idea that oversimplifies six sigma and then declares that mindset is outdated because innovation is needed nowadays – Six Sigma: So Yesterday? [the link Business Week broke was removed].
My guess would be that what leads to this quote is not a lack of understanding that managers need the same qualities today they needed 10 years ago but the compulsion to feed the media frenzy for some incredible new insight. It just isn’t sexy to say “we need the same leadership qualities we needed in the past.” Deming stressed the importance of these “new” qualities he states more than 50 years ago
Yes execution of six sigma often focused too much on cost reduction, optimizing short term projects (which resulted in sub-optimizing the entire system), ranking and rating employees… But innovation is not harmed by a good six sigma program – in fact a good six sigma effort a decade ago understood the importance of innovation perfectly well.
