provides many frameworks and
processes, but also presents a philosophical perspective on IA and IA architecture.
This philosophy attempts to get at root principles of why. As an architect, you are
very interested in why. Why IA. Why this is a risk. Why addressing this risk is a
priority.

Why
architecture
? If one were to say, “I've engaged an architect!” you would
likely picture a building construction project. A building architect provides guid-

works closely with the owner or sponsor for the building. The architect discovers
the owner's goals and desires. These goals and desires include functional aspects
of the building as well as aesthetic aspects. Moreover, the architect considers the
environment in which the building will reside, including the climate, sunrise, and
sunset, all with the intent to create a useful, efficient, aesthetically pleasing struc-
ture. The architect creates elevations, models, and finally blueprints that describe
the relationship among the building site and the building's floors, walls, light, and
space, all of which have been designed to meet the owner's requirements.
What if the construction project were to build a business, a nationwide enter-
prise, or a global enterprise? Initial thoughts would be to engage accountants, law-
yers, and business professionals in marketing, supply line management, and other
