As computer systems have mobed into user environments, the need to design systems that are easy to learn and easy to use has become clearly evident. One of IBM's most successful systems from a usability standpoint is the System/38. In our first paper, Botterill presents the design approaches that were used to develop the System/38 interface, which is effectively used by operations, systems, and user personnel. Although the system has extensive function, including full interactive capability, its design has met the objectives of ease of learning and ease of use. The approaches described should be beneficial in forming the basis for futre usability designs.
