The simple checklist has gotten a lot of press recently.
A couple years back Atul Gawande published his popular Checklist Manifesto, recounting the use of checklists in the operating room and arguing that this marvelous tool can be used to reduce injuries and quality errors. On the wave of checklist mania also rides a group of pilots who call themselves Check Six who make a strong case for the precision of checklists allowing for quite amazing feats of gravity done safely.
