Abstract
This paper describes an experiment that investigated the effects on design productivity and quality of displaying design constraint violations or design errors to the designer when using a case tool for early lifecycle system design. A laboratory experiment was conducted in which the design activity was carried out using an instrumented tool that was developed to support the experiment. Two versions of the case tool were used, one which displayed constraint violations and one which did not. We found that the display of constraint violations had a significant impact on the productivity of the designer by slowing the design process. There was not a statistically significant difference in the quality of designs at the end of the design exercise although subjects with constraint violation notification had 61% fewer errors in their designs.
