Enterprise Architecture
EA brings the visualisation of your organisation, showing you what is happening and how it is carried out within the organisation. It has five major parts. These five parts help to align Information Technology with the operations of your business. Details of these five architectures appear below.
Enterprise Architecture, gives a Blue Print of an organisation and its operations, similar to the Blue Print of a building!
In practical terms, an EA orchestrates the IT, to the tune of the business.
To understand what EA is and how it works, we need to use the analogy of places where people live and the need for architecture and engineering.
If you want to build a hut for one or two people to live, in a remote place, you can build it yourself, the way you want it, without the need for any professional assistance. However, you have to compromise on facilities, luxuries, and comforts as well as re-
But, in the case of constructing a large building which accommodates hundreds of people, in an urban environment, with all the modern facilities and luxuries, the need for an Architect to design the building becomes absolutely necessary..
Because, only an Architect will know how to convert your dreams and wishes into an elegant looking building that will fit in within the chosen environment. This building of your dream will also include compliance with the laws, rules, regulations and health & safety issues among various other aspects prevalent in that environment.
Likewise, for an organisation to work as a single entity, though several employees might be employed in that organisation in various functional departments and branches, it requires a SYSTEM.
In the modern world, to make that system work the way you want, consistently and constantly, you need Information Technology (IT).
For this IT based system to function smoothly 24 x 7 and serve the business purposes as expected, you need IT ARCHITECTS to design the system and IT Engineers to construct, i.e.: develop, them.
IT Architects, document their designs as ENTERPRISE ARCHITECTURES (EA), made up of five component architectures.
The 5 component architectures are, Business Architecture, Information/Data Architecture, Application/Software Architecture, Technical Architecture and Security Architecture. These are shown in the diagram appearing at the top of this page.
