Proud to be a war quant

I’ve just re-read Douglas W Hubbard’s The Failure of Risk Management.  It’s an odd book in that while I agree with most of what’s in it, I’m not particularly convinced by the overall story suggested by the subtitle: Why It’s Broken and How to Fix It. Hubbard’s theme is that we do not do enough, […]

Antifragility

Antifragility is the topic of Nassim Nicholas Taleb’s last book in his trilogy on our uncertain world and how to deal with it.  The other two were Fooled by Randomness and The Black Swan.  These are both relatively narrow in their scope – though well worth their own reviews at some point – whilst Antifragility gives […]

Always look on the bright side of life

Matthew Leitch has asked some questions on my Risk workshops post which I think are aimed at my use of terminology and, specifically, the treatment of good things which could happen.  This seemed to be worth its own Wandering. The term I’d prefer to use about the clouds of vagueness wreathing the ways things will work out […]

Fools and liars

My ears are burning (metaphorically).  I’ve just read Bent Flyvbjerg’s paper on quality control and due diligence in project management.  His theme is the inaccuracy in forecast project costs and benefits.  Specifically, the tendency to underestimate costs and overestimate benefits is attributed to the ‘planning fallacy’, a creation of our old friends Tversky, Kahneman and co.  The source of […]

Risk registers, bloody risk registers

It all sounds so simple.  Just make a list of all the risks.  Then you can start figuring out how to prioritise them and manage them in a comprehensive and visible way.  Job done. This was how it seemed back in the early 90s when we took some tools that had proven quite effective for the management of […]

5%

One of my previous Wanderings mused on the power of soundbites, and specifically the encomium, “nothing between men is 3 to 1.”  Turned into more mathematical language we get the Harry the Horse Theorem: in a two point sample space where the outcome is affected by the action of humans, managers, or anyone else who thinks […]

What’s the use of risk?

This week the the IRM held its Annual Lecture at the Willis Building.  This is a longstanding sponsored breakfast event which used to be held at the old Willis building at Ten Trinity Square.  It’s usually a thought-provoking occasion though since Willis’s move to Lime Street health and safety considerations have somehow stopped them dishing up bacon and sausage sandwiches.  Such […]

Complexity, cockroaches and building resilience

The near collapse of the financial system was fairly widely predicted though the political community is somewhat in denial about that. What was less widely foreseen was that it would happen in September 2008: it was a risk waiting to materialise as we risk geeks say. Two authors with a gold-plated prediction record on this, […]
