Murphy's Law for Engineers

The popular version of Murphy's Law is:
      If anything can go wrong, it will
However, the real version of Murphy's Law, for professionals is:
      If anything can go wrong, it will
  therefore
      We should investigate all possible ways it can go wrong,
      and make sure that these cannot happen

Murphy caused the law, but he didn't formulate the law. According to Spark1, who investigated the origins of Murphy's Law, it was first launched at a press conference. The journalists apparently only used the first line and people use this version as an excuse that they couldn't have done anything about it. For professionals, however, the full law is essential. Things we develop shouldn't go wrong and there is much more than we think we can do to prevent things going wrong.
