Enterprise Architecture

  

The fundamental characteristics of Enterprise Architecture (EA) can be described as follows:

  • EA is a holistic approach to documenting and managing an enterprise’s current and future states in terms of strategy, business processes and technology.

  • The adoption of EA can enable enterprises to make informed decisions and to implement the decisions as efficient as possible.

  • In governance, an EA program needs to address the dynamic and political nature of enterprises thereby making EA a pragmatic, organizational exercise.

  • The distinction between making decisions and implementing them is especially important from a strategic perspective. This stresses the dual purpose of EA to enable enterprises to:​​​​

>  Do things right (operational effectiveness)

>  Do the right things (strategy)

 

Purpose of Enterprise Architecture 

The purpose of EA is the greater alignment between IT and business concerns. The main purpose of enterprise architecture is to guide the process of planning and designing the IT/IS capabilities of an enterprise in order to meet desired organizational objectives.

Benefits of Enterprise Architecture 

The enterprise architecture benefits include: more efficient business operation with lower costs; more shared capabilities; lower management costs; more flexible workforce; more organization; less duplication and redundancies; and improved business productivity.

An effective Enterprise Architecture can bring important benefits to the organization. Specific benefits of an Enterprise Architecture include:

 

-More effective and efficient business operations:

  • Lower business operation costs

  • More agile organization

  • Business capabilities shared across the organization

  • Lower change management costs

  • More flexible workforce

  • Improved business productivity

-More effective and efficient Digital Transformation and IT operations:

  • Extending effective reach of the enterprise through digital capability

  • Bringing all components of the enterprise into a harmonized environment

  • Lower software development, support, and maintenance costs

  • Increased portability of applications

  • Improved interoperability and easier system and network management

  • Improved ability to address critical enterprise-wide issues like security

  • Easier upgrade and exchange of system components

-Better return on existing investment, reduced risk for future investment:

  • Reduced complexity in the business and IT

  • Maximum return on investment in existing business and IT infrastructure

  • The flexibility to make, buy, or out-source business and IT solutions

  • Reduced risk overall in new investments and their cost of ownership

-Faster, simpler, and cheaper procurement:

  • Buying decisions are simpler, because the information governing procurement is readily available in a coherent plan

  • The procurement process is faster - maximizing procurement speed and flexibility without sacrificing architectural coherence

  • The ability to procure heterogeneous, multi-vendor open systems

Benefits of Adopting an EA Framework

An enterprise architecture framework (EA framework) defines how to create and use enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system.  Examples include TOGAF, DoDAF, FEAF, and Zachman.
