The users cant/shouldnt expect everything to be spoon fed! The Option is
there! just because the user forgets ,it isnt a design flaw.
A crash is not the error of the car manufacturer but the driver, the
manufacturer has provided the breaks its upto the user to use it! Only
faulty breaks are design flaws.
If the system makes it incredibly easy, it's a design flaw. If your car manufacturer provides brakes,
but puts them somewhere inaccessible, where you can't get to them
quickly in an emergency, it's a design flaw. Yes, this is ridiculous,
but it was your example. Not mine.
Martin's concern is certainly valid, but it may be something that should be dealt with at the application level and not by the system itself.
How do we differentiate a presentation done for an audience , and a
rehearsal? we cant!
Is there a difference at all?
