Checklists are one of the most powerful universal tool I know for avoiding/minimizing disasters/failures. In the context of software, I try to create user interfaces as masked checklists, because it forces making critical steps/decisions visible and clear (common domain specific understanding for both developer and end user), and guides user to goal. It's almost like old-school "wizard" UIs, but professionals in mind instead of beginners. Also, critical business processes are great expressed as checklists.
