My friend Peh has posted an article in his blog about 5S here. It is written in Chinese but the gist of it is this:
"Japan is a developed country. Visitors Japan are impressed by their cleanliness, discipline and first class service. They excel in many areas especially in the management of 5S.
In contrast, here in Singapore, 5S is not well regarded. Bad housekeeping practices can be seen everywhere including our educational institutions. If our kids are regularly exposed to such messy surroundings in school, when they grow up and join society, they will adopt the same standards."
In contrast Japanese students are indoctrinated with good 5S disciplines in schools. Read about it here.
