This is an open content presentation on enterprise architecture. The target users are ICT Service Manager and Executive, Administrator, and Corporate Planner.
The goal is to build a common reference, terminology, and practices on enterprise architecture to support the strategic and tactical goals of government, education and SME through information and communications technology.
It brings a "get started" guidance to usher in an integrative process approach in assessment, development, delivery and support of the enterprise wide ICT architecture envisioned to meet the strategic business and service goals of the organization.
Enterprise Architecture Definition: (from EWITA)
Enterprise Architecture is generally defined in terms of its constituent architectures, namely:
-
Business architecture
-
Application/software architecture
-
Technology/infrastructure architecture
-
Information architecture
A fairly general definition of architecture in the system space (versus civil or building architectures), is:
Architecture is the high-level definition of the structure of a system, which is comprised of parts, their interrelationships, and externally visible properties.
With this definition in mind, it is all the more obvious that Enterprise Architecture is more than the collection of the constituent architectures (Business, Application, Technology, and Information). The interrelationships among these architectures, and their joint properties, are essential to the Enterprise Architecture. That is to say, these architectures should not be approached in isolation. Together, they are intended to address important Enterprise-wide concerns, such as:
-
meeting stakeholder needs
-
aligning IT with the business
-
seamless integration and data sharing
-
security and dependability
-
data integrity, consistency
-
reducing duplication
