With all the associated enterprise architecture benefits, more and more organisations are using Enterprise Architecture for successful delivery of Information Systems.
The enterprise architecture benefits include the following:
- Simplification of an enterprise. The enterprise architecture benefits include more efficient business operation with lower costs, more shared capabilities, lower management costs, more flexible workforce, more organisation, less duplication and redundancies and improved business productivity.
- Align technology operation to the business wants .The enterprise architecture benefits include help to analyse business models and create an enterprise wide transformation project portfolio which guides decisions and investments. It also increases the return on business and IT investments.
- Align enterprise components to strategy. The enterprise architecture benefits include help in supporting strategic changes such as the due diligence for mergers and acquisitions and management of the resulting integration programme, the design of a new organisation, business model and business operating model, introduction of regulatory and legal changes , introduction of new technology, platforms and infrastructure such as SaaS, Cloud etc. and consolidation of the existing portfolio of people, processes, application and infrastructure etc.
- More Effective IT operation. EA helps in 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 and easier upgrade and exchange of system components.
- Effective management and exploitation of information through IT. EA helps in Identifying areas for consolidating and reducing costs, improve executive decision making, increase the benefits from innovation and manage business transformation activities.
- Better return on existing investment, reduced risk for future investment. EA helps in 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.
Enterprise Architecture is not an approach to fix just one type of problem but applies to many.Hence, constructing up a right architecture depends on the quality of the planning process. The selection of a particular framework or just having EA is rarely the key to success .Instead; it is how the framework is applied that makes a difference. The EA that fits an enterprise often is a mix of multiple frameworks. It’s a long term commitment with continuous improvements and not just a “one-off”. It should be a “live” document that needs to be updated when necessary.
Also, this won’t solve all the problems, but just help assess which those problems are and it is up to the management to fix it.
While designing the architecture, there should be a focus on the business requirements and the strategic goals and how can Information Technology help to achieve both.
A well organised Information system can help an enterprise to have integrated and improved information about the organisation‘s resources. This, in turn, will enable better communication and common understanding between different stakeholders and helps to reduce re-work and duplicated efforts, more profitability, and quicker time to market, improve strategy execution and even reduced IT costs.
