Since attending the Seminar by Gartner on Enterprise Architecture last year I have been focussing on formalising my IT Architecture skills (well when time allows!!). TOGAF (The Open Group Architecture Framework) 9 appears to be the way to go. You can think of it much the same way as PRINCE2 is to Project Management – its something that provides the core principles but it needs to be tailored to the organisational specifics.
Came across “TOGAF 9 in pictures” available on http://www.orbussoftware.com/downloads which is a really effective way of getting to grips with the core concepts.
Also (on the same site) found a stencil for ArchiMate; Archimate is a means of standardising the way that Enterprise Architecture is defined at a high level. Chapter 2 of the specification makes good reading – has a nice summary on why EA: http://www.opengroup.org/archimate/doc/ts_archimate/index.html
From my research IT Architecture (in particular Enterprise Architecture) still seems to be something that different people and organisations view differently – in particular role definitions / responsibilities seem to vary massively. I also fear that often the goal behind EA initiatives aren’t clear enough and some organisations just want to “tick the EA box” rather than get true value from it.
