(From "The checklist manifesto. How to get things right" Atul Gawande Metropolitan Press 2010)
Easy to use even in difficult situations
(Do not spell out everything, check lists can not fly planes).
Provides reminders only in most critical and important steps
Words should be simple and exact
Should use usual language used in profession
Should fit in 1 page, free of clutter and unnecessary colors
Use of upper case and lower case letters (to make it easy to read)
San serif is better (Helvetica)!
Vague and imprecise
Hard to use
Treats people using them as dumb and try to spell out every single step
Turns people's brain off, rather than turning them on
Checklist contents should not exceed 5-7 points (that are "killer points")
Should not exceed 60-90 sec for a "pause point". After this, the check list becomes a distraction. People start to "shotcut" steps.
