Organizational Coupling as a Leading Indicator of Microservice Architecture Degradation

Title:Artifact Package for Organizational Coupling as a Leading Indicator of Microservice Architecture Degradation “Organizational Coupling → Service Degradation” Study Description:This artifact package enables full reproduction of the empirical results reported in the paper “Organizational Coupling → Service Degradation”. The artifact implements a three-stage analysis pipeline: Change Impact Analyzer (CIMET2) – extracts architectural degradation metrics (e.g., stdLOMLC, maxSSIC) from repository history. OC Computation Module – computes weekly Organizational Coupling (OC) values from version control and service mappings. Analytic Processing Pipeline – performs causality testing, recurrence analysis, robustness checks, and early-warning modeling. The package includes: All source code required to reproduce the analyses Step-by-step documentation (README and INSTALL guides) Pre-produced intermediate and final results under the Data/ directory A sample combined dataset used as analytic input The artifact reproduces: Granger causality results Prewhitened cross-correlation analyses Early-warning performance metrics (AUC-PR, precision@k) Recurrence pattern outputs Robustness and transformation analyses All outputs are generated as CSV artifacts and stored in structured data folders. The package is self-contained and does not require NDA-restricted data.
