Aggregated enterprise architecture wisdom
What is a service? And what do services do? Seems like it’s time to re-explore some of the routine questions that come up almost every day in a service-oriented enterprise-architecture… not least because these questions are right at the core of the Enterprise Canvas model. And, in turn, the discipline and rigour about services that modelling […]
In designing management-structures, why is it so often assumed that responsibility-relationships only go one way? Our organisations often place enormous attention on insubordination, a refusal or failure to follow ‘orders from above’; yet why don’t they place the same level of attention on insuperordination, the refusal or failure to respect the the same relationships and […]
In enterprise-architecture, how do we disentangle business-function, business-capability and business-service? This one’s for Adam Johnson, particularly as a follow-on to his comment to the previous post ‘More on EA and asset-types [Part 4]‘: I perceived your usage of function to be business function at a certain level of abstraction that could be perceived as a […]
What are the different types of assets that we need to deal with in an enterprise-architecture? What implications arise across the architecture from the differences between these types? In the first post in this series, we identified four distinct asset-dimensions: physical: physical ‘thing’ – independent, tangible, transferrable, alienable virtual: data, information, idea – independent, non-tangible, transferrable, non-alienable […]

“What would be the smallest service? Did anyone ever look for the/a boundary condition of a service?” – an important pair of questions from Jan van Til in an earlier comment here. The first question is a bit difficult, because the only correct answer would be that ultimately it’s right down at the sub-cellular level – […]
Why is management the way that it is? Does it work well that way? And what part does the architecture of management play in determining how well it does or doesn’t work? (This is probably another politically-risky post for me to play with, but never mind… ) In recent weeks I’ve repeatedly come across four […]
On Twitter, Brenda Michelson of Elemental Links started a conversation with the question: Do #entarch frameworks enable or constrain practice of (value from) enterprise architecture? In my comments back to Brenda, it became clear to me that there’s a trap that many teams fall into, not just Enterprise Architecture, and that’s falling into an inward […]
In the Wired magazine article on the relationship between AT&T and Apple (see: Bad Connection: Inside the iPhone Network Meltdown), the author, Fred Vogelstein, presents a classic service management problem. In the early days of the iPhone, when data usage was coming in at levels 50% higher than what AT&T projected, AT&T Senior VP Kris […]
This article (Can SOA Give You Good Service) identifies some of the troubles withwords when dealing with all the Service terms. I found it a very helpful article indeed because it helps keep Service and SOA on the straight and narrow. Nice call out of …
