In support of the "Review Architecture" activities the required set of documentation is gathered. The basic documentation needed are the defined IT architecture view, the sets of models to be reviewed. Ancillary information is also gathered such as requirements, scope, strategy and planning documents associated with the IT architecture.

The set of documentation gathered together (from the list below) for any given review is dependent upon the level (i.e. Business, Logical or Technical) and type of IT architecture (i.e. Complex or Simple) being reviewed.
