Consider the following disasters:
-New software at Hewlett-Packard Co. was supposed to get orders in and out the door faster at the computer giant. Instead, a botched deployment cut into earnings in a big way in August and executives got fired.
-Last month, a system that controls communications between commercial jets and air traffic controllers in southern California shut off because some maintenance had not been performed.
-Computer code foul-ups also recently held Tacoma, Wash.ís budget hostage, delayed financial aid to university students in Indiana and caused retailer Ross Stores Inc.ís profits to plummet 40 percent after a merchandise-tracking system failed.
What do all of these things have in common? What is the common root cause? Bad software? Sloppy programming? Oh, no. The common cause is human error.
