How can you say Six Sigma is bullshit?

It’s literally just a method of identifying a problem, measuring and analyzing its impact, and implementing a lasting solution.

The difference between the six sigma method and traditional organizations is that:

• Six sigma gives power to experts (instead of middle managers), * It involves staff who are actually doing the work
• It tests solutions before they’re implemented
• It acknowledges that many things can’t be forced top-down by the boss

You say that probably because many components in it look like common sense.

“Duh, of course the response to a problem should be to rectify it” (simplifying slightly)

Lots of companies don’t though. Or they jump to a conclusion about the best solution. Or some middle manager decides he knows what’s best and then proceeds to break things.

It’s quite useful to have a philosophy that gives authority to non-traditional but logical steps.

I mean, that’s what people do with models and methodologies right? In my language English terms are used when using an English methodology.

Kaizen comes from Japan, was developed in Japan, and it was quite successful there. It’s not that strange to copy it word for word.

The idea behind it is quite different from what tends to happen in traditional Western companies. Since companies want to be better than their competitors and organizational change is hard, it makes sense to look for ready-made tools, rather than try to reinvent the wheel.

Of course, since (organizational) change makes many employees nervous, depending on how the organization goes about it Kaizen could get a bad name.
