Enterprise Architecture
Starting in 2000 the Department of Technology and Enterprise Business Solutions initiated an Enterprise Architecture program that resulted in the official publishing of the Montgomery County Technical Architecture document in 2003. The architecture has been updated on a roughly yearly basis since that time.
The County’s Enterprise Architecture effort is based around maintaining an Enterprise Architecture that defines the following:
-
Business Architecture – defines the business strategy, processes, business domains, and governance
-
Technical Architecture – defines the IT infrastructure and standards
-
Application Architecture – Application architecture and standards
-
Performance Architecture - Business and EA Domain metrics
Each component architecture is interrelated and supportive of the others. The sum total of all the subcomponent architectures make up the County Enterprise Architecture Standard. The relationships among the component architectures is illustrated in the following diagram:
The County has one Enterprise Architecture that is released as a roll-up Architecture Document.
The latest release (November 2022) was a rewrite of the Architecture and is located here. It is considered an interim release as the Enterprise Architect program is undergoing a transition. A new release is anticipated reflecting the updated program.
The purpose of the Enterprise Architecture is to communicate:
-
the results of County business decisions (related to IT);
-
the County IT Architecture and infrastructure;
-
how the County manages its data; and
-
how the County builds or acquires applications.
In general, it communicates how the organization has invested in its IT infrastructure (including hardware, software, processes and people). The County continues to make significant investments in IT and must communicate to many parties how future investments align or impact the architecture and infrastructure.
