Happy Opposite Day!  Today is a great way to think about how you would look at business problems, design and even requirements from a different perspective.  Trying going through a business process backwards to gain a different perspective.  Instead of walking through the steps to complete a form online in order, start at the end or just before clicking the submit button and work backwards.  Changing your perspective can lead to uncovering better requirements for business rules, business process and design in general.  The physical act of doing something backwards forces your brain to think in completely new ways.  You can easily see how this works by simply walking down the hallway backwards or even driving a different route to work.  Give it a try!
