Behavioural effects of attitudes toward constraint in CASE: the impact of development task and project phase

This paper examines the effects of systems development task and phase upon individuals' attitudes and behaviour while using computer-aided systems eng ineering (CASE) tools. A previous empirical study of developers in several countries is revisited. Findings indicate that the mediating effects of tas k and phase upon the relationship among constraints, attitudes and behaviou r are weak. They thereby support earlier research, which claims significanc e between attitudes and behaviour, by eliminating the potentially mediating effects of task and phase. Findings also indicate that CASE tool users ass ociate implementation, integration and maintenance in terms of tasks and co nstraints, suggesting a reassessment of traditional life cycle models.
