The case for enterprise architecture – part 1

Enterprise architecture projects require investment. Not only in monetary, but also in time and skills. The question arises: Why should we consider the implementation of Enterprise Architecture? The answer has to do with the many varied benefits that formalized enterprise architecture brings with it.

Considering just the impact through information technology, according to Ross, Weil and Robertson (2006) the benefits of enterprise architecture are noticeable in the areas of Information Technology (IT) costs, response of IT, management of risk, satisfaction levels of management and the achievement of strategic business objectives.

Standardization and the disciplined execution of IT processes save the enterprise money due to more efficient, visible processes and reduction in time spent on IT support and maintenance. Having clearly defined process aids the effort towards optimization, re-engineering and the monitoring and measurement of operational IT processes.

Better defined and executed IT process also aids in the responsiveness of the IT departments. Systems development is aided by re-use of modular components which reduces time to rollout to the benefit of the systems and user audience.

From a risk perspective, enterprise architecture leads to reduced business risk, increased continuance and a reduction of security breaches. Better systems, uptime and reduced risk contribute to improved management satisfaction with IT and its ability to delivers.

The most compelling reason is the ability of enterprise architecture to facilitate achievement of enterprise objectives. Better systems allows for more customer focus and reaction on customer demand with improved and innovative products. Alignment between business and the systems that support it facilitates rapid change and repositioning in the market in order to meet market demand and opportunity.
