Earlier this month, Jeff Johnson appeared on the BayCHI program to speak about the updated version of his GUI Bloopers book.
As Jeff put it, he ran through examples of all but the last of his categories of bloopers very quickly, because the last category -- management bloopers -- "is where the real problem is, since so many bloopers continue to be made."
Here is Jeff's list of management bloopers:
As described by Jeff, development typically occurs with no UI design, no UI standards or guidelines, and no oversight.
Why is this still true?
Note that a list of all of the bloopers and blooper categories is presented on the book's website.
Note also that Jeff said that when writing the first edition of the book (published March 2000), it was hard to find any bloopers in Apple products. However, "that is no longer the case."
