ABSTRACT
It is not altogether uncommon for medical device companies to spend several months developing a preliminary user-interface design only to be dissatisfied with the result. Such firms can come to regard a product’s user interface as its Achilles’ heel, especially in cases where their competition has already brought a more user-friendly product to market. As a result, manufacturers may seek an objective third party such as a usability or human factors engineer, graphic designer, or marketing professional to enhance their product’s usability and appeal without a major overhaul, given their schedule and budget limitations.
