Six Sigma is more popular than Lean
Google Trends: lean manufacturing, six sigma
More fun with “Google Trends.” Six Sigma (red line) is a much more popular search term in Google than Lean Manufacdturing (blue line). It looks like about a 7:1 ratio. That surprises me.

I’m not surprised. If you look at job postings many require six sigma certification of some degree or other, but only rarely do they mention any kind of lean qualifications. A person’s interests are usually where the money lies.
It depends on the number of permutations of the word. Lean manufacturing is not an absolute term, as six sigma is. It would be more “fair” to compare just “lean” and “six sigma”. However that would also add alot of non manufacturing stuff.
Alas, statistics is devil’s tool ;)
Well, I have to disagree. Do a Googlefight.com on “lean” versus “six sigma” (with quotes).
Lean: 82,600,000 results
Six Sigma: 14,700,000 results
well, if you search for “lean manufacturing”, you’re right. But is Lean only toward manufacturing ? I don’t think so (I’m in the service ;)
I guess part of the problem is that “lean” is very generic term and would bring up diet plans, etc. I originally started, looking to compare “lean manufacturing” and “lean healthcare”, but lean healthcare hadn’t received enough searches to count.
Are the results really significant? No, not at all. What conclusion was I trying to draw…. none really. Just a fun thing to look at.
For what it’s worth, Googlefight results:
5S = 17,000,000
Six Sigma = 14,700,000
