Enterprise Resource Planning (ERP) transformations often experience requirement volatility and governance complexity during fit-gap analysis. This study examines requirement drift during the Procure-to-Pay module implementation of the Integrated Education Management System (IEMS) at Independent University Bangladesh. Using version comparison of fit-gap artefacts, governance workshop records, and change logs, the study identifies governance escalation as a primary driver of requirement reclassification and traceability degradation. The findings show that requirement drift in institutional ERP environments is frequently governance-mediated rather than purely technical. The paper proposes a layered conceptual model linking stakeholder negotiation, governance escalation, architectural constraints, and AI-supported decision mediation. The study contributes to requirements engineering and enterprise systems literature by reframing fit-gap analysis as a governance-mediated adaptive process. This work is released as a working paper to support further research and doctoral study in AI-enabled requirements engineering and enterprise architecture governance.
