The Meaning of 5S

I write a lot about 5s, both in this blog and for my company. We get a lot of business from people interested in how labels can support, create and maintain the visual workspace.

But when is something a true 5S implementation and when is it just good business sense?
Take for example those wondrous little guide lights in parking garages - you know, the ones that tell you how many spaces are available in each row/section of the garage, saving both time and hassle.

They certainly visually organize the environment, they keep it clean and well organized and they sustain this organization.

But is it a true 5S implementation?

Pehsk's blog has a recent post maintaining that it is.

I can certainly see how it contains elements of 5S, and I can see how it benefits the garage and the consumer. I can also see how it empowers the individual user (in this case a driver) to make an informed decision about where to drive.

Take a look at some of his photos, and let me know what you think?
Is it lean, is it 5S - or is it just good solid business sense?
Is there a difference?

... And does it matter?
