Six Sigma on the wane

An article in Business Week suggests that the six sigma quality improvement practice is on the wane. It’s another of those management fads that seemed to take hold of the US especially with a degree of fanaticism, but now reality has begun to set in. After you have done the job of reviewing and improving processes, there are other things that need to be addressed which six sigma can’t do.

I expect it will go the same way as its predecessors – TQM, process re-engineering, CRM – not relegated but remembered as much for its problems as its benefits. And I hope that it will allow for a more realistic appraisal of whether a major proponent, Jack Welsh, actually did much good for business.
