Pervasives and the VSM algedonic link

How do we keep on track to enterprise purpose? Perhaps more to the point, how can we know when we’re falling off-track, in time to recover? To me, one of the keys here is the perhaps least-known part of the

Redrawing the Viable System Model diagram

I’ve been arguing repeatedly that trying to get the Viable System Model from overviews, introductions and writings based on or about it, can put the curious mind in a state of confusion or simply lead to wrong interpretations. The absolute minimum is reading at least once each of the three books explaining the model. But […]

Cognitive Dissonance

I was reading this today: http://it.toolbox.com/blogs/ea-matters/is-there-an-enterprise-architect-paradox-surely-is-57728?rss=1 It is a good analysis of the cognitive dissonance between what Enterprise Architects should be doing and the role and situation they often actually find themselves in. The term Enterprise Architect has been hijacked for far too long. An Enterprise Architect should indeed be a senior leadership role, ideally reporting to […]

Requisite-variety and stormy weather

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 […]

Strategy Planning and Enterprise Architecture – dealing with the devil in the detail

Enterprise Architecture is all about supporting strategic planning and business transformation activities, although many organisations seem to almost wilfully forget that this is one of the main purposes of Enterprise Architecture if not the most important one. A business strategy is a long-term plan of changes for the whole enterprise which will address things like offering new products an […]

Enterprise Canvas as service-viability checklist

One of the more valuable uses of the Enterprise Canvas is as a checklist to verify completeness and viability of services, in any context within the enterprise. By ‘completeness’ I mean that we check that the service has all the connections and support and flows that it needs to play its full part in the […]

Upward and sideways from business-model (short version)

As all-too-usual, the previous ‘how-to’ post ‘Upwards sideways from business-model‘ – to complement the earlier post on transforming from Business Model Canvas to Archimate, to plan and verify the implementation – has turned out to be huge, because it included all of the explanation and context. Here’s a stripped-down version without any of the explanation […]

Upwards and sideways from business-model

The past few posts in this series have focussed on moving ‘downward’ from the business-model, towards implementation, such as might be modelled in Archimate notation. That’s an aspect of the business-architecture / enterprise-architecture interface that makes immediate and practical sense to most people.
Yet to complete and verify the business-model and its proposed implementation, we also […]

The Viable System Model is the missing theory behind Enterprise Architecture

I am currently involved with the EAST group (an outreach group of SCiO http://www.scio.org.uk/ ) which is looking at the overlap between Enterprise Architecture and System Thinking, and in particular the Viable System Model (VSM). The Viable System Model has been around for many years, coming out of Stafford Beer’s work  http://en.wikipedia.org/wiki/Anthony_Stafford_Beer This diagram looks complex at […]
