While some of software engineering's basic assumptions seem intuitive, the need for scientific experimentation remains clear. Empirical validation is the hallmark of a mature scientific or engineering discipline. However, little precise experimentation is performed in computer science, especially in the area of software engineering. Several assumptions are made about the factors affecting software reuse, specifically concerning the role of human factors such as managerial influence. This paper describes the results of a controlled experiment designed to evaluate the impact of human factors on software reuse. The experiment concludes that (1) software reuse promotes higher productivity than no reuse, (2) reuse resulting from both moderate and strong encouragement promote higher productivity than no reuse, and (3) while strong managerial encouragement did not create a significant difference in productivity, it does tend to promote improper reuse activities.
