Supplementary Material: Dynamic Project Complexity and Static Financial–Contractual Governance

This record contains the supplementary material and supporting documentation for the manuscript entitled “Dynamic Project Complexity and Static Financial–Contractual Governance: A Misfit Model for Industrial Project Performance.” The supplementary material provides the methodological audit trail for construct development, expert screening, calibration of the 9 × 6 complexity–demand matrix, validation design, robustness checks, predictive-diagnostic evidence, evidence-source safeguards and managerial-use interpretation. The materials support transparency and replicability while excluding identifiable project-level records and confidential organisation-specific data.
