Information architecture
What is information architecture?
Information architecture is how a product's content is organised, labelled and connected so people can find things and know where they are. It is the floor plan beneath the interface - invisible when it works, maddening when it doesn't.
Also known as: IA, content structure
The demo
Same nine options, two ways of arranging them. Your task: click where you would go to do the thing below. Try it in the flat list, then switch to the organised version and feel the difference.
Find where you'd go to: return an order
Pick the option that fits the task.
What this demo shows (text version)
Nine options - track a parcel, return an order, change delivery address, update password, notification settings, close account, add a card, view invoices, apply a voucher. The task is to find where you would go to return an order, which is the option "Return an order".
In flat mode the nine options sit in a single unordered jumble, so finding the right one means scanning all of them. In organised mode the same options are grouped under headings - Orders, Account, Payment - so "Return an order" is plainly under Orders and you can ignore two-thirds of the list. The content is identical; the grouping and labelling are what make it findable.
In the flat list you had to scan everything to find one item; in the organised version you went straight to the right heading and the rest fell away. Nothing changed about the content - only how it was grouped and named. That gap is information architecture earning its keep.
Good IA is built from the user's categories, not the company's org chart. The fastest way to get the groupings wrong is to mirror your internal teams; the fastest way to get them right is to watch how people actually sort the content - a card sort - and label each group in their words, not your jargon.
Labels do as much work as the structure. A perfectly logical group hidden behind a clever name nobody recognises is as good as missing. Plain, expected labels beat clever ones every time - "Returns" finds more than "Reverse logistics", however neatly the boxes are arranged behind it.
