Abstract

Though there is a wide agreement that software technologies should be empirically investigated and assessed, software engineering faces a number of specific challenges and we have reached a point where it is time to step back and reflect on them. Technologies evolve fast, there is a wide variety of conditions (including human factors) under which they can possibly be used, and their assessment can be made with respect to a large number of criteria. Furthermore, only limited resources can be dedicated to the evaluation of software technologies as compared to their development. If we take an example, the development and evaluation of the Unified Modeling Language (UML) as an analysis and design representation, major revisions of the standard are proposed every few years, many specialized “profiles” of UML are being developed (e.g., for performance and real-time) and evolved, it can be used within the context of a variety of development methodologies which use different subsets of the standard in various ways, and it can be assessed with respect to its impact on system comprehension, the design decision process, but also code generation, test automation, and many other criteria. Given the above statement and example, important questions logically follow: (1) What can be a realistic role for empirical investigation in software engineering? (2) What strategies should be adopted to get the most out of available resources for empirical research? (3) What does constitute a useful body of empirical evidence?
