At the Open Group meeting in Austin a couple of weeks ago, I attended the workshops on IT risk assessment. Pretty dull, eh? In fact, this topic produced some of the liveliest debate I’ve ever had at a conference.
Unless you specialize in this area, you may think that risk assessment is pretty well sewn-up. You couldn’t be more wrong. Get 50 practitioners in a room and you will have 50 different methodologies for assessing IT risk. The trouble is that nearly all of them will be subjective – the outcome of any risk assessment exercise is most likely to be ‘high’, medium’ or ‘low’. Even when it’s an apparently objective number -- 54,821, for example – you don’t learn all that much. Try going to your board and telling them that their IT risk is 54,821 and their eyes are likely to glaze over very quickly! Any attempt to calculate ‘annual loss expectancy’, although valiant, only results in trouble when the degree of variability is larger than the sum itself!
