Debate
The difficulty in establishing a common definition for "information architecture" arises partly from the term's existence in multiple fields. In the field of
systems design, for example, information architecture is a component of
enterprise architecture
Enterprise architecture (EA) is a business function concerned with the structures and behaviours of a business, especially business roles and processes that create and use business data. The international definition according to the Federation of ...
that deals with the information component when describing the structure of an enterprise.
While the definition of information architecture is relatively well-established in the field of systems design, it is much more debatable within the context of online information (i.e., websites). Andrew Dillon refers to the latter as the "big IA–little IA debate".
[.] In the little IA view, information architecture is essentially the application of
information science to
