Fragility of Markets and Architecture Failure

As the NASDAQ exchange came to a grinding halt this past week, I, as well as many of you perhaps thought about system failure and what was the series of events and initial conditions that preceded the shutdown. Did a human did something strange that set a series of events in motion that jeopardized the…

Real-time sensemaking with SCAN

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 […]

On sensemaking in enterprise-architecture [4]

How do we make sense of uniqueness in enterprise-architecture? How do we support decisions at ‘business-speed’ – especially when the context is in part unique? And what architectural support do we need to provide for sensemaking and decision-making at business-speed? In the first part of this series we looked briefly at uniqueness, and why it’s […]

Domains and dimensions in SCAN

What are the sensemaking-domains in SCAN? What are the boundaries between those domains? A great challenge in an earlier comment from Roger Sessions, where he asked me for the mathematical basis for those domains and boundaries. I think he was a bit shocked when I said there wasn’t one – but in fact there is […]

On sensemaking in enterprise-architectures [3]

How do we make sense of uniqueness? How can we use uniqueness? And how do we make appropriate decisions when some or all of a context is inherently unique? In the first post in this series, we skimmed through Max Boisot’s I-Space and its impact on sensemaking in relation to complex-adaptive-systems. I then added a […]

On sensemaking in enterprise-architectures [2]

How do we make sense of uniqueness? How can we make sense of what’s happening at the exact moment of action? In the previous post in this series, I looked briefly at Boisot’s I-Space – promoted by some as ‘the answer’ to everything in the information-space – and discovered that, useful though it may be […]

On sensemaking in enterprise-architectures [1]

We know how to do sensemaking in enterprise-architectures; but why do we do it? What’s the purpose? What’s the point? As a result of various recent proddings from Bruce Waltuck and Stephen Law, amongst others, I’ve finally gotten round to taking a more than just a cursory glance at Max Boisot‘s concept of information-space, or […]

When effort estimations feel like buying showroom kitchens

Purchasing a showroom kitchen can be an unpleasant experience, especially if you’re not sure of the value of what you are buying. Kitchen showrooms tend to have the atmosphere of a prestigious car dealership, perhaps because the price tag of a well-designed kitchen is similar to a mid-sized car. If you happen to linger at […]
