Check lists are an often overlooked tool. They can be both simple and effective if they are used correctly. The classic check list we can all think of is one used by an airline pilot to check his/her plane before a flight. And not many of us would be comfortable being on a flights if we knew the pilot had skipped the pre-flight checklist.
Too often checklists are used solely as a downstream tool to ensure that x is doing their job correctly. Or they are used by a manger in the hope that if they put one in place then the problem will go away and the manager's job is done.
I was shopping recently and as I exited the changing room I noticed the checklist shown below. The other white marks are where paint has peeled from the wall.
In this situation it is obvious that the feedback part of the deal is not happening. And I do mean DEAL. The implicit DEAL with a check list is - You follow the procedure and sign off that you are doing it and I or the Company will give you the tools and resources to make sure you can do your job and when things are out of specification corrective action will happen.
