Aggregated enterprise architecture wisdom
Year after year I am finding that Enterprise Architecture certifications are becoming more important to architects. Back in 2007, I remember reading an article from Gene Leganza called, “Is EA Certification Important?”. In that article he stated that 65% of…
#entarch Like many complex capabilities, enterprise architecture operates at several different tempi. (See my post on Enterprise Tempo.) A workshop at the SEI last year identified three tempi, which it called “Operating Modes”.

On December 1st we see the first revised TOGAF 9 specification since its release in 2009. This brings TOGAF to version 9.1 with 450 changes that addressed 400 comments from EA practitioners. This release promises downward compatibility to the TOGAF…
Why do we need enterprise-architecture in a business? And why does that EA need to be broader than just IT, often all the way out to a true enterprise-wide scope? One reason is implied this Tweet by Belgian consultant Patrick Van Renterghem: itworks: Big discussion now about what happens when cloud vendors go bankrupt or out-of-service. […]
In enterprise-architecture, in what sense are we using the word ‘enterprise’? As adjective, or as noun? This is another point of language that turns out to be surprisingly important… We can use ‘enterprise’ as adjective, to describe a scope for something else. That’s the sense that’s used in classic IT-oriented ‘enterprise-architecture’: the context or concern is IT-architecture, […]
Ends and means are not the same: everyone knows it’s not a good idea to mix them up. The same is true of ‘enterprise’ and ‘organisation’.

If the choice-point itself is a true moment of chaos – a point where literally anything is possible – then what is it that guides us through each of those infinitesimal yet ubiquitous […]

I’m currently sifting through my past blog-posts of the past five years or so, with a view to republishing some of them in ebook-format, to make them more accessible in a more convenient and more portable form. So far there are well over 400 blog-posts here on enterprise-architecture and related themes, plus a few more […]
What do we do when we don’t know what to do? – and how do we ensure that whatever we do is the right thing to do? How do we make sense fast, at business-speed? I’ve been tussling with this one for quite a while, most recently culminating with a simple sensemaking framework called SCAN: The horizontal green-line […]
