moneyscience: Steve Jobs dies aged 56 - http:/
To be available is normally expressed in up time over a one year horizon, so if I was to say to you this service is 99.885845% reliable, you may think that is a great statistic but in reality you can expect 10 hours worth of accumulated outage in a single year of operation.
Is that good?
Well let's hope it is a cumulative measure over 365 days especially if you depend on the service, like that of a jet engine in an aeroplane. Fret not for those like me who dislike flying, the majority of turbines being manufactured today are running "6 Nines" and most aircraft are able to fly on a single engine once they are cruising.
 Adding Redundancy
 Reducing Tail Events
 Operational Simplification
You guessed it, finance was going to appear in this blog post seeing that is where I spend most of my time working and I left the finance bunch for the end of this article. In my opinion financial services would rate pretty poorly in our resilience factor ranking argument and if some of these banks were to run airlines, many of us would never want to fly again.
On the resilience factor, manufacturing experience is probably more widely dispersed from a global perspective and in some parts of the world construction would fall into that bucket as well. The banking sector however has been showing a deteriorated level of standards when it comes to resilience and in the year of 2011 many jurisdictions have been unable to run through a single event horizon without living through a critical failure. In short, the banks need to do more work.
