The evaluation of EA performance


The Enterprise Architecture delivers value, as soon as it is modelled. It does that, gradually, while it is implemented, by increasing the effectiveness and efficiency of your Enterprise.

EA soon becomes an asset in its own, returning value to your Enterprise. 


The EA scope is key, since more scope returns more value. EA iterations add scope and as such new value. 
When looking only at the benefits of standardising technology and integrating applications in IT, the benefits are limited. With the business architecture in scope, the picture changes significantly. The IT to Business alignment, for instance, occurs only if you develop a full Enterprise Architecture.


Hence, the EA success should be measured against scope rather than against an abstract EA that does not have an agreed definition but promises the lot, in vague terms. Yet, while, in pratice, it covers only IT, Its value is advertised as for an enterprise wide EA.


To evaluate the performance of EA at the enterprise as a whole level, you have to measure, for instance, the degree of increased enterprise agility with KPI such as Time To Market.

Or you may estimate the improvement in operation efficiency from the alignment of technology to business operation. 


The Key Performance Indicators (KPIs) may be grouped then in a few categories: 

– operational (those measuring the enhancment in the enterprise operation reliability, responses…) 

– development (quantifying improvement of capability, product development… processes)

– governance (evidencing better understanding, communication and decision making in the organisation) 

– enterprise support (measuring optimisation of support processes) 


While the EA performance evaluation method suggested in the article measures the effectiveness of the EA team, tt does not evaluate the degree of business improvement realised as a result of EA which is what really matters to stakeholders. 

In other words, the evaluation of EA performance should be rooted in the enterprise performance enhancement because this is what the business and management really expect.
