Abstract: | From a survey of 201 people concerned with information-system design, estimates for 83 systems indicate that on average 30—35, per cent of operational software is devoted to the user-system interface (USI). In the design of USI software, survey responses indicate that improvements are needed in requirements definition, design documentation and design guidelines. |
