Making the case for enterprise architecture
Conclusion: Many organisations have integrated enterprise architecture (EA) into the business processes, whilst many have not. To some, it is a religious argument as to why the ICT group even needs to have people with ‘architect’ in their name; for others, the EA group is the watchdog of the system, ensuring both new capabilities and changes to existing capabilities will be fit for purpose.
Like most things in business, the cost versus benefit analysis to justify why any activity is a priority is essential before committing effort and resources to it. EA should be no different. Organisations should complete a business case assessment to justify why EA is necessary for their business model, and what form it should take.
In doing so, both business and ICT will jointly have a better understanding of the value EA brings to the enterprise, be able to manage expectations on what EA can deliver and judge its effectiveness.
