01
ECL Programme Blueprint
Programme and governance
Set scope, ownership, measurement routes, review cadence, and evidence expectations before model complexity takes over the conversation.
02
Data Architecture, Integrity and Segmentation
Data foundation
Create the data foundation for ECL through source mapping, segmentation logic, reconciliations, exceptions, and readiness checks that reviewers can trust.
03
SICR Framework and Stage Transfer Governance
Stage transfer governance
Establish significant increase in credit risk through quantitative and qualitative indicators, backstops, cure logic, and review workflow that management can defend.
04
PD, LGD and EAD Modelling Framework
Model architecture
Translate policy into model architecture using PD, LGD, EAD, term structure logic, calibration discipline, and portfolio fit that remain explainable.
05
Overlay Framework and Disclosure Narrative
Reporting and judgement
Capture emerging risks and model limitations in a controlled way, then connect adjustments to movement analysis, approvals, and disclosure-ready narrative.
06
Controls, Documentation and Audit Readiness
Controls and assurance
Support maker-checker workflow, reconciliations, version awareness, approval records, and evidence packs that keep ECL repeatable and review-ready.
