have many uses in addition to IA

assist in identifying the essential questions surrounding the following, where X

Business perspective
The business need for X
The business fit of X
The business justification for X
Technical perspective
The technical fit of X
The technical development and delivery of X
The technical mechanisms of X
The use of the technical mechanisms
IA perspective
The business need for IA
The business fit for IA
The business justification for IA
The technical fit of IA
The technical acquisition/development and delivery of IA
The operations and maintenance of IA technical mechanisms
The use of IA (i.e., IA implications to the user community)
The frameworks are applicable to far more than just IA; therefore, we isolate IA as
a special consideration for the IA architect. The EPIA framework is as follows:
