ABSTRACT
INTRODUCTION In Chapter 9, we discourage folks from blaming the user for making mistakes when operating a medical device. We assert that most use errors are induced by a medical device’s hardware and software user interface design flaws and not by user ineptitude in various forms. Disbelievers need only to observe a few usability test sessions to witness the pattern of repeated use errors that particular user interface design flaws can induce if the device has not already been “scrubbed clean” of such flaws.
