Information Architecture
Définition
Information Architecture (IA) is the art and science of organizing and structuring the content and navigation of a digital product (website or application) to make it findable, usable, and understandable. It constitutes the logical foundation that defines how the user will access information without excessive cognitive effort. IA is based on the proper management of nomenclature (naming categories), navigation (possible paths), and hierarchy (relationship between pages and content).
Exemple
On a large e-commerce site, IA determines whether a user searching for a "men's short-sleeved linen shirt" should find it under "Clothing > Men > Tops > Shirts" or under "Clothing > Materials > Linen > Shirts." IA, often determined by Card Sorting, ensures that the chosen path is the one that makes the most sense to the average user, and not to the company's internal organization.
