Engineering for usability (panel session): lessons from the user derived interface (original) (raw)

1985

Abstract

ABSTRACT The focus here is on the lessons learned from the UDI project for building usability into the software development process. In the UDI project we attempted to engineer a usable system. That process involved:defining an appropriate metric for measuring usability,setting explicit levels of usability to be achieveddetermining an appropriate methodology for building usability into the system,delivering a seemingly functional system with an easily changed interface very early in the development cycle, andrecognizing the tentative nature of the initial design.Using the UDI project as an example, each of the above principles will be discussed in detail.
