Abstract

The general ethos of producing structured programs has been, at least in theory, adopted throughout the software engineering community. By studying and measuring the structure of existing software we can estimate the benefits to be gained from changes in the structure in terms of the external attributes (perceived behaviour) of the re- structured software. [13, 2, 3, 10, 6, 7]. In this paper we report the results of two controlled experiments measuring the improvement on the maintainability of differently structured code. These experiments build on the experience and insights gained through an earlier experiment [5]. We discuss a strategy for re-structuring based on an improved re-engineering factor [9]
