BP oil spill clearly foreseeable on monitoring software, official

  There is a real conflict when designing systems for control of these types of processes, between "too much alarming" and "not enough alarming". They both have the same consequence -- a lack of trust in the control software. The too much alarming case is obvious, but the too little case also leads to a lack of trust like this: 1. software doesn't alarm when operator thinks it should 2. bad consequence 3. thoughts of "software doesn't work" 4. valid alarm not trusted in the same way too many false positives. This sequence of events is not necessarily rational, but it is human non-the-less. There is a lot of really cool work going on, and a lot more to be done, in this space. Current best practices include lots of training for operators, who do an awful lot of "flying the factory by feelings and hunches", rather than by good, informed software interaction.

  Here is a related interesting article on what any industry can learn from this incident in regards to risk management and regulatory oversight. Two pointers: 1) Ensure layers of controls are implemented and tested for known risks. 2) Do not underestimate or ignore the low risk vulnerabilities. It does not take many in aggregate to result in catastrophe. http://www.redspin.com/blog/2011/01/07/lessons-learned-from-the-bp-well-blowout-for-your-industry/ http://www.redspin.com/blog/2011/01/07/lessons-learned-from-...
