Visual controls must at the very minimum be unambiguous, and either indicate normal versus abnormal or to positively specify a problem condition in order to be useful.

This attempt at visual management raises more questions than it answers. What is the intended designation of “normal versus abnormal”? What
Here is another recent find on visual management: the website of MediFilm “the leaders in healthcare visual management systems”. Who knew there was such a thing to be leaders of? Well done in any case, making a product out of an specialty application of graphics which can be applied to
Visual controls must by definition be clear indicators of normal versus abnormal, go versus no go, okay versus not okay.
