There has been a recent recognition by systems designers of the necessity for considering the needs and preferences of the user of on-line computers. Very little empirical evidence exists for guiding user-oriented design efforts. In this study, two levels of interface flexibility, the users prior experience on-line, and terminal type were investigated as possible determinants of user satisfaction and performance. The task consisted of text correction with an on-line text editor. A general linear models statistical technique controlled for the effects of measurable but uncontrollable variables. Interface flexibility, operationalized as alternatives to the user, is not uniformly effective in producing optimal performance for all users, nor in producing optimal perceptions of satisfaction. An attempt was made to specify the kinds of users for whom flexibility is best. Author
