From craft to science

Abstract

Empirical software engineering (SE) research is often criticized for poorly designed and reported studies, a lack of replications to build up bodies of knowledge, and little practical relevance. In this paper, we discuss issues in empirical software architecture research as an illustration of these issues in one subfield of SE and as a step towards better understanding empirical research in SE in general. Based on feedback from software architecture researchers and practitioners, we explore why, despite persistent discussions in the SE research community, there are still disagreements about why and how to conduct empirical research. Then, we explore how empirical SE research can progress beyond one-off studies and endless new and exciting results toward SE research as a mature science. This would allow us to establish foundations for evaluating existing and future empirical research and help researchers design and publish better studies.
