ERP Roadmaps on SAP S/4HANA — POV by Dr. Dodi Mossafer

Summary

An effective S/4HANA roadmap sequences foundation before features: chart of accounts and decision rights, fit-to-standard with governed extensions, and a benefits register that survives audit. The aim is a stable run state where the ERP is the source of truth for operating and financial decisions.

1) The Framework

Establish the Control Spine First

Design the chart of accounts, cost objects, and decision rights before features.
Map end-to-end data lineage from source systems to subledgers, general ledger, and group reporting.
Create a close and reporting calendar that matches the operating rhythm of the organization.

Adopt Standard Processes and Govern Extensions

Adopt standard processes where the majority of needs are met; document clear exceptions.
Use a governed catalog for reports, integrations, customizations, conversions, and workflows with value and control gates.
Favor a simple, well-documented data model to reduce rework, outages, and testing effort.

Prove Value and Transition to Run State

Maintain a benefits register tied to income statement impact and cash flow impact.
Instrument key performance indicators in the system, not in slides or spreadsheets.
Move from stabilization through hypercare into steady-state ownership with clear roles and measures.

2) Working Principles

The enterprise platform is a system of control: demonstrations follow decision rights and policy, not the reverse.
Design for audit: embed lineage, approvals, and policy checks in the workflow.
Discipline on scope: every non-standard item must clear a value or control threshold.
Adoption over activation: measure use inside the tool of work by role and process.

3) Use Cases and Applications

Financial Core and Reporting

Accelerate the financial close with one trusted record.

Materiality thresholds, standardized recurring journals, and automated reconciliations.
Intercompany processing with clear ownership and automated eliminations.
Group reporting aligned to management views and statutory requirements.

Operations and Supply Chain

Integrate materials management, production, sales, and distribution with costing and inventory signals.

Available-to-promise, production variance transparency, and controlled backlog management.
Governed backflush, batch, and lot traceability end to end.
Product profitability aligned from the first cost object to the management report.

Public and Regulated Entities

Fund accounting, grants, and transparency by design.

Fund and program restrictions enforced in the chart of accounts and workflows.
Grant burn-rate reporting linked to evidence and procurement trails.
External reporting aligned to compliance calendars and audit packs.

4) Project Examples for Deployment

Higher Education — Multi-Campus University

Roadmap implementation focused on fund control and position-based planning.

Chart of accounts and fund redesign: create a simplified fund structure with program, grant, and restriction segments; enforce controls in workflow.
Position control and budgeting: connect positions, labor cost planning, and encumbrances to financial plans and monthly variance reviews.
Grant lifecycle transparency: standardize intake, budget, allowability checks, spend controls, and sponsor reporting with evidence links.

Transportation and Logistics — National Carrier

Roadmap implementation focused on order fulfillment, asset health, and working capital.

Order-to-cash standardization: harmonize customer master data, pricing, billing, and revenue recognition with automated controls.
Asset lifecycle and maintenance planning: integrate fixed assets, maintenance schedules, parts inventory, and downtime reporting.
Inventory and network visibility: implement available-to-promise, shortage alerts, and reconciliation to the general ledger each close.

Humanitarian Nonprofit — International Programs

Roadmap implementation focused on restricted funds and country office accountability.

Restricted fund governance: encode donor restrictions in the chart of accounts, prevent miscoding at entry, and enable exception workflows.
Grant-to-project planning: link grant agreements to projects, budgets, procurements, and field expenditure with document evidence.
Public transparency portal: publish program financials and outcomes sourced directly from the system with audit-ready lineage.

These are concrete road-ready implementations that organizations can adopt and sequence on a 12- to 18-month roadmap, moving from design to steady-state ownership.

5) Metrics and Signal Loops

Lead Indicators

Defect and backlog burn-down after go-live, with owner and due date.
Adoption by role measured as transactions per user in the tool of work.
Cycle time for change requests and approvals by governance tier.
Data quality scores across master data with remediation logs.

Lag Indicators

Financial close duration and reconciliation exceptions trend.
Working capital performance, including days sales outstanding, days payables outstanding, and inventory turns.
Service levels, reliability, and unit economics by product, program, or route.
Audit findings and remediation cycle time.

6) Common Failure Modes

Feature chasing: customizing before decision rights and the chart of accounts are settled.
Shadow processes: spreadsheets and side systems that break lineage and controls.
Ungoverned custom work: integrations and reports that lack a value or control justification.
Activation without adoption: celebrating go-live without run-state ownership, measures, and training.

7) Practical Artifacts

Chart of accounts and cost object design pack with decision maps and examples.
Fit-to-standard catalog and an extension gate with value and control criteria.
Data migration playbook with quality rules, reconciliation steps, and cutover evidence.
Close and reporting calendar with a role inventory, responsibilities, and forums.
Benefits register with baselines, accountable owners, and counterfactual documentation.
