System Architecture covers a wide range of information technology infrastructure. One of it’s primary objective is having a working solution seen as part of a whole enterprise architecture, which includes other systems. Its benefits include the ability to share and efficiently process information, to respond faster to changes in technology and business needs, increasing revenue, and reductions in costs. System architecture must be vigorous enough to be changed over time to operate efficiently and efficiently. That is, the ability to support easy exodus to the organization's desired future state from the current state.

The successful systems architecture has to change the minds and attitudes of the stakeholders, drive the highest risks out of the projects, and provide the basis upon which the system may be continuously evolved with minimal alteration. Likewise, a good systems architecture must have the foundation from which systems are built and an architectural model that defines the vision on which the architecture is based. It must be simple, i.e. easy to implement and understand as well as able to work for the current business goal and be scalable to allow easy future modifications.

As business goals change, the system architecture needs to evolve to ensure continued satisfaction of business goals.
