I wouldn't cite grocery stores as a model for "organization" given that their "information architecture" of where things are in relation to another is driven by dark design patterns like "put the most often sought after items at the BACK of the store (like milk / eggs) so people have to walk through and see all the other products". There's nothing "organized" about this insofar as being an optimal organization for anything but manipulating people.
Ohhhh no. It's organized all right, very much so... just not for the customers' benefit.
No no, it's organized for the shops' benefit.
Some hlalmarks:
* Perishables around the edges for quick stocking and restocking. Non-perishables around the middle where they don't need to be changed so much.
* Areas that need environmental controls are grouped: so...
- bakery products in one area, lighting is yellow-gold, air fresheners emitting maltol, etc.
- chilled goods in another area, with a lower ambient lighting level and a different colour palette;
- fresh fruit & veg in another area, lit with greenish light, air fresheners emitting something piney or something herbal-smelling;
And so on.
On the shelves, typical eye-levels and eye-lines measured, premium products put at eye level, budget ones down where they are less visible so fewer shoppers will find them, meaning more stuff with higher profit margins sells;
Tempting fresh stuff is encountered first, in case the customer is hungry, to tempt them.
Boring slow-moving stuff, frozen goods, imperishables, toilet paper etc., right at the end.
It's highly organized but not _for_ you; no, it's organized to exploit you.
