The evaluation of EA performance (IT Toolbox Blogs)

In the Measuring the Performance of Enterprise Architecture, published in Information Week, Imre Kabai proposes an approach to measuring the EA performance.

The article is more clear than most on this theme.


Still, the EA performance is analysed only from the perspective of the EA team rather than the enterprise which is the customer of this effort. Hence, while the work is useful for the strict evaluation of the EA progress, it does not suggest how to measure the enhanced enterprise performance due to EA. Yet, business is only interested in how its performance is improved due to the EA rather than how the EA team evaluates its own performance, internally, in terms of As-Is, Target, Governance, Assurance. 


That is, the  evaluation of the EA performance should tie the business performance to the EA progress rather than in itself, in isolation.

The business, management and other key stakeholders of the enterprise expect to see the benefits for the enterprise rather than a report on the maturity of a potentially sterile EA development.


The EA team itself should be also concerned with assessing the positive impact on the enterprise so that the EA business case is proven and the effort is justified. They need to show how EA reduced unnecessary duplication and variation, how reducing teh architecture debt the operation becomes more efficient and so on.


Because there may be the case where the EA performance measures great but the business sees little benefits. This is often the case today, in particular when EA often follows a particular method specification, for example.


You may surely start by evaluating the reduction of the architecture debt. A proper architecture reduces duplications and overlays in processes, platforms, projects and sometimes people. Therefore, the EA performance should measure the degree of reduction in duplication and unnecessary variation in platforms, technologies, roles…
