I am working with a couple different clients now on their approach to enterprise architecture, and not surprisingly, their approaches are vastly different.
One company has a core group of EA’s, working primarily on what they have named Business Driven Target Architecture, which is a bit of a mix of business, application and data architecture. The scope of these ranges from very project-specific to business-unit wide. In addition to this work, they have other efforts underway to cross-reference their primary work with each other, company and division strategies and trends in business and technology. While their primary work is very solutions oriented, their secondary work is enterprise-wide and will, over time, provide more enterprise views of the business and application landscapes. There is another group that is focused on the technology architecture.
The second client also has two groups working on EA. The first group has been in existence for a few years and is an internal IT group, headed by the full-time Chief Architect, with several architects acting in a part-time EA/part-time solutions architect capacity. The Chief Architect leads the IT architecture effort with internal IT resources , but also is a member of the second group. The second group is composed of a variety of business and IT representatives, with a focus on business architecture and strategy. Without the second group, the internal IT group has struggled to gain the traction necessary for EA to be more effective. The second group is just getting started, but they are already beginning to see more support, especially given the stature of business architecture group’s members and the vocal support of the company’s chief executive.
While these two companies are approaching EA very differently, they both have one very important characteristic in common: They both have a “Business First” approach. The first company starts their Business Driven Target Architectures (notice the First word in the name of their approach) with an understanding of the business goals and strategies, pain points, processes and business capability changes. That is what separates it from a straightforward solutions architecture approach, in addition to the cross-referencing to their secondary work.
The first company, after struggling with traction, also decided there needed to be more of a business first sense to their efforts. So they not only created a Business Architecture Team (there is that word first again), but they also focused the group on defining a holistic business operating model as the context for many of the business process integration and business process standardization (see my earlier post that describes their approach) recommendations.
Both of these companies will continue to modify their EA approach as necessary, but one thing will remain constant: Business First!

EA and SOA Revisited
September 1, 2010There has been a lot of discussion recently on online forums, phone calls and visits with clients and prospects, and in the analyst community about the relationship between enterprise architecture and service-oriented architecture … again.
Three years ago EAdirections did a webinar with David Linthicum entitled “When EA and SOA Worlds Collide.” (Both the presentation and webinar recording are available.) I was recently asked to revisit that presentation with a client for one of their internal meetings as they just got internal approval to implement an ESB as part of their SOA strategy. Based on the recent activity, both within and outside my own conversations, it seems that not a lot has changed in these three years.
We have always positioned SOA as one of the modes of architecture and development that an EA should include, but it is not the entirety of EA. You are still going to have batch feeds and other non-service-oriented modes of systems integration and development. While there has been an increase in the implementation of SOA and the maturity of EA functions, it seems as though the main disconnect that we pointed out in our webinar still exists – Multiple SOA projects going on without being part of an enterprise SOA plan. There are a variety of different reasons for this, but to me, it boils down to the lack of an answer to 2 fundamental questions from a holistic perspective: What services should we build? Who will use them?
In order to answer this question, the scope of analysis must be not only beyond the project level, but beyond the IT perspective. Enterprises need to have a better idea of how they are going to operate, where the opportunities for redundant service delivery are, and where integration should be implemented among its current and future business processes. Business architecture is the key to figuring out the answers to these questions.
So I guess I misspoke (typed) earlier when I said nothing has changed. There has been one very big change in the three years since we did that webinar – business architecture has left the realm of possibility and potential and is positioned to actually help some organizations be more successful with SOA, as well as other modes of architecture within the overall EA.
