The ‘Systems-Thinking’ Enterprise Architect

Even with the best and most complete of models and frameworks, the practice of Enterprise Architecture (EA) in organisations isn’t always effective. Analysis does not always explain everything that happens, and changes that Enterprise Architects (EAs) make do not always deliver the expected benefits.  When EA does not deliver value as expected, or when it cannot be represented as a transparent cause and effect relationship, some EA defenders draw our attention to long delays in the enterprise’s adoption of information technology.  In light of this, EA should be thought of as an investment against things that might otherwise go wrong — kind of like a ‘flu shot for 2025.  Other apologists blame flaws in the EA frameworks and methods used, or in the way that they are used.

‘Nounification’ catches up with Systems Thinking

It seems that certain verbs are becoming nouns, for no particular reason that I can see based in grammar, semantics or the logic of language.  This appears to be a recent phenomena, and in a few cases, nounification has propelled these lucky  innocuous verbs into the noun stratosphere.  The first is the innocent little doer-word ‘reveal’.

rɪˈviːl/
verb
1.
make (previously unknown or secret information) known to others.

Designing in the post-consumer age

Christmas is coming, again.  Last year, Australians reportedly spent $A32B at an average of $A1,200 per person during the silly season.  Nearly twenty million of these gifts with a value of around $A1B were unwanted and were sold, re-gifted, stored or dumped.  For myself, a distinctive marker of post-consumerism came when a ten year-old family member declared a few weeks out from Christmas that he didn’t know what to ask for this year because he couldn’t think of anything he particularly wanted. It seems that between Christmas, birthdays, special days and rewards for good behavior the number of buying opportunities outstrips some family member’s needs or even desires.  So it seems we are now living in an age of post-consumerism, even for ten year-olds.  We are beyond some western models of growth, in uncharted territory.

Slipping the noose on IT project benefits

Every business case for a new IT system must identify and argue for resulting benefits. Benefits management is a well-established competency for ensuring benefits are identified, quantified, tracked and realised. Realised benefits justify the initial investment.  Victoria’s State Treasury, which funds some very large IT projects, including a number that have gone off the rails has started providing much-needed guidance on identifying and planning for anticipated system benefits. In light of continuing problems with large public sector IT projects (Queensland Health payroll system, Victoria’s licensing system)  this is important capability-building.

In the Cloud, no one can hear your integrations scream!

Enterprise software vendors would have us believe that enterprises are flocking to The Cloud, meaning they are subscribing to remotely hosted utility systems and services rather than licensing and hosting them on premise.  The oft-claimed benefits are efficiency (only pay for what you use), simplicity (no more on-premise software) and agility (the software utility can be configured at any time to release new capabilities).

Where’s the Art in Enterprise Architecture?

Vitruvian canon, re-interpreted by Robert Venturi for the Functionalists (from 'Learning from Las Vegas').

Vitruvian canon, re-interpreted by Robert Venturi for the Functionalists (from ‘Learning from Las Vegas’).

I had the opportunity to attend the First Australian Enterprise Architecture Conference, 19th and 20th November 2013, at the iconic Melbourne Cricket Ground. The conference wrapped up with the traditional panel of luminaries. The session touched on some of the recurring themes and topics of the two days – enterprise architecture definitions, identity, what we are, what we do, what we don’t do, frameworks versus ontology, methods and pitfalls, value propositions and rationale.

As it happened, I got to ask the final question of the conference. The following is an improved, expanded and referenced version of the challenge I put to John Zachman and a number of EA practitioners and consultants.

A Systemic Perspective to Managing Complexity with Enterprise Architecture

ASystemicPerspectivetoManagingComplexitywithEnterpriseArchitecture-coverPallab Saha’s book on systemic perspectives for managing complexity with enterprise architecture is now officially published by IGI Global.  I have written Chapter 13, ‘Enterprise Architecture’s Identity Crisis: New Approaches to Complexity for a Maturing Discipline’.  The 18 month process was a reminder of the creation cycle times for this type of content. It seems that social media’s immediacy has done little to escalate the pace or compress the effort of producing a traditional academic work of 26 authors.

When I first started collecting thoughts and materials on what I began to understand as enterprise architecture’sidentity crisis’, I was reacting to my perception that IT-centric EA was increasingly facing a crisis of relevance. My experience of the unrealised promise of EA led me to think and discuss questions of theory, practice and purpose. ‘Identity crisis’ seemed an appropriate metaphor for the challenges facing enterprise architecture.
