Computer-aided software engineering´s impact on the software development process: an experiment

Organizations today invest enormous resources in computer-aided software engineering (CASE) technologies with the hope of gaining significant increases in programmer productivity. In an empirical study, eleven three-person teams, composed of undergraduate Information Systems majors, developed versions of the same software system, a Pascal Pretty Printer; four teams used the same CASE tool and seven teams did not use any CASE tools. The major results of this study are: (1) most of the CASE projects were coded in less time than the non-CASE projects; and (2) all of the CASE projects met more of the requirements than the non-CASE projects. Each of these results was a statistically significant effect
