Describing the Overall Architecture
nColumns: IS components -
data models (what it is made
of), functional models (how it works), and network models (where the components are located); represent physical manifestations of the system. Also
people (who), time (when), and motivation
(why).
nUse of the framework: When IS users bring in a package that follows a data model inconsistent with the rules of the company, a lot will be spent fixing the package.
