Enterprise Architecture

I don’t know

June 12, 2012 by Tom Graves

I don’t know. There – how hard was that to say? For some people, seemingly impossible. But as an enterprise-architect and a generalist, I have to be able to say it often – very often, in fact. Because the fact is that I don’t know most things – not in fine-detail, anyway. Nothing like as well […]

ArchiMate core – Tailoring ArchiMate (5/7)

June 11, 2012 by Bas van Gils & Sven van Dijk

In the previous postings of this series we have introduced the (history of) the ArchiMate language, its underlying framework, the core concepts as well as its extensions. This should give you a good overview of the language. On the one hand it may seem…

Inside-in, inside-out, outside-in, outside-out

June 6, 2012 by Tom Graves

I’ve been brewing how to describe some key distinctions about the way we view our architecture, about how we see its role, and its relationship with everything else in its context.

Requisite-variety and stormy weather

June 1, 2012 by Tom Graves

Just how much of a law is Ashby’s Law of Requisite Variety? Our answers to that question – and likely there’ll be many of them – are fundamental to how we handle key architectural concepts or requirements such as management, control, certainty (or lack of it), complexity, disruption and much, much more. Okay, first, the […]

ArchiMate core – Extension (4/7)

May 31, 2012 by Bas van Gils & Sven van Dijk

In the previous two posts in this series we introduced the core of the ArchiMate languages existing of the three layers and three columns. However, not all questions that enterprise architects typically face are supported by this core. Think for ex…

Assets and services

May 31, 2012 by Tom Graves

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 […]

On ‘stupid’ organisations

May 30, 2012 by Tom Graves

To link up with a discussion on ‘Possible examples of stupidity (or brilliance)‘, on the LnkedIn ‘Organizational Intelligence’ group, Richard Veryard and Geoff Elliott asked me to post this diagram, from my book Everyday Enterprise Architecture: I believe Richard and Geoff want to use this diagram to comment on the current JP Morgan bank-losses case, […]
