Abstract
Effective coordination between contributors with different functional roles is fundamental for the success of collaboration-centric software development paradigms such as DevSecOps. However, quantitatively assessing coordination in such settings has received limited attention. We introduce multi-class socio-technical congruence (MC-STC), an extension of the widely studied socio-technical congruence (STC) framework to address this gap. Our metric enables the assessment of coordination in a setting where contributors with different functional roles or alignments collaborate. Using a large-scale exploratory case study, we evaluated MC-STC for two classes (i.e., 2C-STC). Specifically, we calculated 2C-STC for 100 systematically selected projects from the TravisTorrent dataset, considering developers (dev) and security-focused developers (sf-devs) as the two types of contributors with different functional alignments (i.e., two classes). We hypothesized that the dev and sf-dev interaction would have a quantifiable impact on the vulnerability score (VS) of each project. Our results show a moderate negative association between 2C-STC and VS, with the Spearman correlation reaching −0.427 (p = 0. 00000624), indicating that higher levels of coordination between dev and sf-dev led to projects with a lower incidence of high-severity vulnerabilities. In addition, 2C-STC shows a stronger negative relationship with VS than STC, suggesting that it is the more sensitive indicator of this relationship. Therefore, the specific instantiation of our proposed metric, 2C-STC, performs comparatively better than STC for measuring cross-functional coordination in our selected projects. However, further research is needed to explore its broader applicability.
