I thinking care for the Six Sigma system, but I've found that 5S really "goes" with my personality - maybe its that engineering mindset I've been accused of having
I used a lot of the steps before as well but never really looked at it as a method, just sort of did things as I saw the need. I think the 5S method really focuses on following the steps systematically before the actual need arises.
Anyway, I really like it and its helped me at home too. The only place I can't quite implement it complete yet is with my computer files, but I'm working on it.
