SUBSTRATE AUDIT OS · R2R
P&L Governance
Establish end-to-end governance for P&L reporting — from version-controlled forecast assumptions and owned variance commentary to formally signed management reports — enabling AI-assisted forecasting on a trusted substrate.

TARGET OPERATING MODEL
Current-state process versus the governed, automation-ready future state this blueprint delivers.
CURRENT STATE
1
Forecast assumptions in individual spreadsheets
2
Variance commentary produced ad hoc
3
Management report distributed without formal sign-off
4
Finance Manager as single point of failure
5
No version history for forecast changes
FUTURE STATE
1
Forecast assumptions in version-controlled log with approval workflow
2
Named owner per entity for variance commentary
3
Structured templates with peer review gate
4
Management report sign-off chain enforced in system
5
Finance Manager deputy trained and tested
6
Full audit trail for all forecast changes
ARCHITECTURE PATTERN
Recommended system layers from data source to governance output.
L1
LAYER 1
Forecast Platform
Version-controlled forecast model with assumption log; all changes require approval and generate audit trail.
L2
LAYER 2
Commentary Workspace
Entity-level templates with mandatory fields; peer review gate before submission to consolidation.
L3
LAYER 3
Consolidation Layer
Aggregate commentary and financial data from all entities; consistency check before pack preparation.
L4
LAYER 4
Sign-Off Workflow
Enforced approval chain for management report; version locked on final approval before distribution.
L5
LAYER 5
Distribution Control
Controlled distribution with log; recipients, timestamps, and version recorded.
L6
LAYER 6
Finance Director Dashboard
Forecast accuracy, variance explanation completion, sign-off status, and governance score trend.

DELIVERY ROADMAP
Sequenced implementation programme from governance foundation to closed-loop optimisation.
PHASE 1 · LIVE NOW
Assumption & Ownership Foundation
Weeks 1–3
Catalogue forecast assumptions
Assign variance ownership per entity
Create commentary templates
Establish deputy coverage
MILESTONE
Assumption log live; ownership register published; deputy trained
PHASE 2
Workflow Controls
Weeks 3–10
Implement version-control for forecast
Build sign-off chain
Deploy commentary workspace
Configure distribution control
MILESTONE
Sign-off chain used for 100% of reports; all assumptions version-controlled
PHASE 3
Automated Commentary Checks
Weeks 8–14
Automate mandatory field check
Deploy variance threshold alerts
Implement consistency validation at consolidation
MILESTONE
Commentary completion rate above 98%; no consolidation delays
PHASE 4
AI-Assisted Forecasting
Weeks 14+
Train model on assumption history and actuals
Deploy driver-based forecast suggestions
Continuous model calibration
MILESTONE
Forecast accuracy improvement measurable; assumption changes declining
AUTOMATION READINESS GATES
GATES PENDING
These governance conditions must be confirmed before automation can be safely deployed on this process. Meridian does not recommend automating until all gates are met.
All forecast assumption changes processed via version-controlled workflow for two cycles
Governance
Named variance owner producing commentary for all entities for two cycles
Dependency
Peer review gate in use for 100% of commentary submissions
Audit Trail
Sign-off chain used for 100% of management reports for two cycles
Audit Trail
Finance Manager deputy successfully covered during absence
Dependency
Governance score above 65 (Governed band)
Governance
Readiness gates are governance conditions, not technical prerequisites. Each gate maps to a source dimension: Governance score, Audit trail completeness, Dependency risk, or Drift status.
