This author argues that "IA is foundational and also critical for both users and organizations" - and extends from infrastructure to user interface. This article provides a checklist of architectural aspects to examine and questions to ask.
" Abstract
Government environments often have prescribed complex processes for obtaining and implementing technology solutions. In order to encourage and enable information architecture (IA) in government systems, it is essential to embed IA within the current processes and to view IA as part of the overall architectural framework. The definition of IA used here is broad and inclusive spanning applications, the Web and the enterprise. A common focus exists aimed at organizing information for findability, manageability and usefulness, but the definition also includes infrastructure to support organization of information. This case study describes the development of an IA checklist in a large United States government agency. The checklist is part of an architectural review process that is applied 1) during assessment of proposed information systems projects and 2) design of solution recommendations before system implementation.
