The purpose of this
activity is to update the Business Perspective architectural views after: the solution to an issue has been defined, a
change to the business has been defined or as a result of the planned introduction of a new technology.
Description
Multiple iterations are done to update the required Business level models, with enough detail defined to support the
objectives of the IT architecture. Many activities can be done in parallel, but good communications is needed in order
to keep the models consistent, but good tool support makes this a non-issue. The following items are produced:
Business Entity Model for the system;
Business Process Model for the system;
Business Locations Model for the system;
Business Roles Model for the system;
Update the Architecture Glossary and define Architectural Decisions as required.
Once the perspective is updated a peer review is done to decide if the IT architecture is complete, or if additional
iterations are required.
These activities are best carried out by a small team staffed by cross-functional team members, lead by an IT
architect. Issues that are typically architecturally significant include data, process, locations, and roles. The team
should include members with business domain experience and also modelers. The team should also have experience with model organization and
layering. From the provided inputs, the team will need to be able to synthesize the architecture views.
Usage
Usage Guidance
The Business level will only need updating if there is a fundamental change in the business. This change is:
Business Driven - the organization desires to fundamentally change its products and/or
services;
Technology Driven - an opportunity or issue based upon current of future technology requires the
business to fundamentally change.
Typically these business-level changes are centered upon changes to business processes, but they may also involve the
creation of totally new products or services and a set of new process to support them.
