Six Sigma, with or with out 'Lean' methodologies, are primaraly used in manufactoring and in large corporations with processes. Can it also work with small businesses in the service industry. The U.S. is about %75 service, would it make sence to start focusing more in that industry?
My problem with it is results are slow to come.
Everything has to be this big project.
Not exactly nimble and quick.
I could only see it as a success in the service industry
if things were rigidly timed. Say a six sigma project
on a drive thru preformance. the mechanics of fast service.
Yes, it can be easily applied to the service industry. It is all about process improvements. In my Black Belt classes, over half of our case studies involved transactional processes.
I am not a big believer in ‘Lean’… The DMADDD model to me is a better way to go if you want to decrease cycle times. Of course, a lot of it is just differences in terminology.
