Hey Tony, great meeting you at SNW - San Diego last week. <div>&nbsp;</div> I hate that the pubilc release is that it was "operator error". Doesn't that stop short of the real problem?<div>&nbsp;</div> How about the 'system' had inadequate controls that understood that the HUMAN, a fallable entity, would be part of the SYSTEM. Systems should be engineered knowing that parts (humans) will fail (make mistakes).<div>&nbsp;</div> Reminds me of an explanation of pilot error - that I've always liked: "Pilot error is what a committee of experts determines over months of thorough and exhaustive research with seemingly limitless resources, what the pilot should have done, with roughly 20 seconds to make that same analysis."<div>&nbsp;</div> Now you've got me going - I'll try and blog something more on this, this afternoon.<div>&nbsp;</div> ..clark (

Clark, it is so true. A system should be designed for no single points of failure and this should include single points of "operator" failure. The latest I heard before leaving Bogota was that the electric company was contemplating lucite plastic covers that snap over the switches involved, so that a technician would have to take an overt act to open the cover before hitting a switch. At least that's an improvement.
