Studying Software Flaws

On the one hand, it is frustrating that so few studies of software faults have been published to guide researchers in finding ways of detecting, ameliorating, or preventing these faults from happening. On the other hand, it is not at all surprising that projects are reluctant to make such sensitive data public because of internal politics or external competitiveness in software-intensive businesses.

Despite this paucity of studies and the reluctance of companies to make data available, there is a set of landmark studies about software faults that provide useful foundations for product and process improvements. Endres [Endres 1975], Schneidewind and Hoffmann [Schneidewind and Hoffmann 1979], and Glass [Glass 1981] reported on various fault analyses of software development. A weakness in their work is that they do not delineate interface faults as a specific category.

Thayer, Lipow, and Nelson [Thayer et al. 1978] and Bowen [Bowen 1980] provide extensive categorization of faults, but with a relatively narrow view of interface faults. Basili and Perricone [Basili and Perricone 1984] offer the most comprehensive study of problems encountered in the development phase of a medium-scale system, reporting data on the fault, the number of components affected, the type of the fault, and the effort required to correct the fault. Interface faults were the largest class of faults (39% of the faults).

We note, however, that none of these studies address the kinds of problems ...
