We have the world of information at our finger-tips. Our operational tools get better every day. Yet things still go wrong on a regular basis. Then we take the opportunity to prove that there is no problem so bad that you can't make it worse. Why do we screw up? And why do we then screw up trying to fix it? My favourite magic-pixie-dust quick-win cure-whatever-ails-you fix (no seriously this time) is checklists.
