This paper introduces a systematic procedure for operationalizing software engineering theories, focusing on translating abstract concepts into measurable elements for empirical validation. The procedure extends Sjoberg et al.'s operationalization framework and formulates non-causal hypotheses based on Dubin's approach, defining variables, selecting indicators, and systematically deriving hypotheses. The methodology is illustrated using the DevOps Team Taxonomies Theory, providing a replicable guideline for researchers.
Grounding software engineering theories in empirical evidence just got easier: this paper offers a systematic, replicable procedure for translating abstract concepts into testable hypotheses.
Software Engineering often adapts theory-building frameworks from the social sciences to address socio-technical complexity. The key phases of the theory-building process are conceptual development, operationalization, testing, and application. Operationalization translates abstract concepts into measurable elements for empirical validation. This phase is essential for delivering the practical utility required by an applied science like Software Engineering. We propose a systematic procedure for the operationalization phase that bridges the gap between abstract concepts and empirical validation, ensuring the resulting theory is both rigorous and practically useful. We extend the operationalization framework proposed by Sj{\o}berg et al. and formulate non-causal hypotheses following Dubin's approach. Our procedure defines variables, selects indicators, and systematically derives hypotheses. We present a replicable, evidence-based methodological guideline that preserves a clear chain of evidence and supports practical validation. We illustrate the procedure using the DevOps Team Taxonomies Theory. This guideline provides a transparent chain of evidence from theory to testable elements, empowering researchers to ground theoretical advancements in empirical evidence and deliver actionable insights for practitioners.
