Trying to understand IaaS, and other nonsense

There's been something upsetting me about the whole notion of Infrastructure as a Service. It has taken me a while to put my finger on it, but here goes. But first, an analogy with electricity usage and provisioning.When I flick on the…

I demand he shoots me now….

We talk about bit rot, and information death. But there is a corollary – fact rot, and truth death. Either I am loosing my mind, or I have fallen into the incongruity of a bad television script and it’s 1994 again. In…

Services, customers and citizens

If we provide a service that is a monopoly or natural-monopoly, how should we relate with those who use our services? What’s the most appropriate metaphor to use, to guide our decision-making? I’ve been thinking hard about this for quite a while…

Product and service

What’s the difference between product and service? And in what ways does that difference affect the various aspects of enterprise-architectures? This question came up as a follow-on to an unusually-good LinkedIn discussion, started on The Enterprise Architecture Network list by Michael Clarkson,…

Assets and services

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…

Insuperordination

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…

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…

More on EA and asset-types [4]

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’ –…

More on EA and asset-types [3]

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 looked at the concept of four distinct asset-dimensions:…

What is the boundary of a service?

“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…

Rethinking the architecture of management

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…

Maintaining a Service Mentailty

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…
