Advancing Business and IT Architecture – Business Context Architecture (BCA)

In a previous blog post titled Advancement in Business and IT Architecture, I introduced Role-based Domain Architecture (RDA) as a method to advance the state of the art for business and IT Architecture, to fully support services based architectures and emerging platform based architectures based on services.  In the next few posts we will delve deeper into the RDA layers to get better acquainted with RDA as well as a simple and lightweight tool called QuickRDA that captures architecture information for RDA and provides the means to generate graphical views of the models.  This next post focuses on the Business Context Architecture (BCA).

Advancement in Business and IT Architecture

When is the last time we’ve seen truly new thinking in the area of Architecture for business and IT systems?  Zachman Framework, 1984?  TOGAF, 1990’s?  OMG Model Driven Architecture, 2001?  Has there been any breakthrough thinking other than to continue to provide more clarification and more decomposition about how to document enterprise and IT architecture?  There has, but change is painful even for a profession that prides itself in facilitating change.

SOA, EA and Cloud - Are they now synonymous?

cloud-computing.jpgJoe McKendrick had a blog post a while back that asked Do SOA and Enterprise Architecture now mean the same thing? I’ve said in the past that cloud is also very dependent on good EA (at least above to IaaS layer).


I personally view that EA is about the alignment of enterprise business goals with technological initiatives from an end-to-end perspective.  SOA is about the assembly of functionality from services is definitely impacts the Enterprise Architecture as it’s defined but is a subset. Going forward I firmly believe that it will take on a great portion of the EA as more of the items that used to be in the EA are hidden in services coming from SaaS vendors.


Getting the most out of the cloud is definitely one of the roles that EA will need to take on. All these different buzzwords do address the issue that businesses expect differentiated value from their IT systems and at the same time lower costs and higher quality. These techniques will all need to come together to make that happen going forward.

When does a fad just become part of reality?

Recently there have been a number of blog posts again that have been talking about the death of SOA (again!). As I look around, the death of SOA discussions started way back in January of last year. Back when we were starting this blog, I did a number of entries around service oriented architectures - but that was half a decade ago. Sure there were some fad-like tendencies around SOA just like there are around Cloud. I'd state that SOA was a pre-requisite for cloud to move beyond IaaS.

It does remind me of a situation back when I was at a large non-US government client in the late-90s who said "What about that whole object oriented buzz a few years back, whatever became of that." In that case, it was that OO was so omnipresent that it was indistinguishable in the technology they were using. It was just part of the way things were. I believe SOA has entering that same situation. The techniques are now everywhere, therefore it is a non-issue.

At least it is not the other situation, I've encountered -- I used to be part of the AI group that supported GM in the late 80s - early 90s. There it was always a feeling that: "If we can do it, it can't be AI."
