Design to Deployment for SAP (S/4HANA) — POV by Dr. Dodi Mossafer

Summary

An audit-ready SAP deployment runs on a simple idea: design for control and decisions first; build only what’s needed; migrate clean data; cut over with evidence; and govern adoption until value shows up in P&L, cash, and unit economics.

1) The Framework

Design the Control Spine

Chart of accounts, cost objects, and decision rights mapped to governance forums.
End-to-end lineage defined from source systems to subledgers to the Universal Journal to group reporting.
Financial close and reporting calendar aligned to the operating rhythm.

Build and Data with Governance

Catalog for reports, interfaces, conversions, enhancements, forms, and workflows gated by value and control criteria.
Data design with master and reference standards, quality rules, ownership, and stewardship.
Testing approach from unit to process to integration to controls with clear exit criteria.

Cutover, Deployment, and Run State

Cutover ledger prepared with trial balances and reconciliation evidence.
Stabilization and hypercare service level agreements tied to business key performance indicators.
Benefits register attested each quarter with exit criteria to steady state ownership.

2) Working Principles

Controls precede features: demonstrations follow decision rights and policy, not the reverse.
Build less, govern more: simplicity reduces outages and accelerates measurable value.
Design for audit: evidence trails are embedded in workflow and data lineage.
Adoption over activation: measure use in the flow of work by role and process.

3) Use Cases and Applications

Financial Core (Financial Accounting and Controlling)

Accelerate the close with one number culture.

Materiality rules, standardized journals, and automated intercompany processing.
Universal Journal established as the single spine to enterprise performance management.
Benefits tracked to controllable variance and cash flow.

Manufacturing and Supply (Materials Management, Production Planning, Sales and Distribution)

Throughput and inventory signal loops that can be audited.

Available-to-promise, governed backflush, and batch or lot traceability with clear ownership.
Costing and profitability transparency at the product and channel level.
Linked plan and actual data to support make, move, and sell decisions.

Projects, Grants, and Capital (Project Systems, Investment Management, Funds)

Capitalize correctly and prove value to outcomes.

Stage-gate funding with evidence-backed capitalization.
Grant restrictions and fund accounting enforced in process.
Run-state reporting aligned to the governance cadence.

4) Project Snapshots (anonymized)

Consumer Packaged Goods — Global

Design to deployment focused on the control spine and inventory signals.

Chart of accounts simplified and Universal Journal connected to enterprise performance management.
Production variance visibility enabled across plants with governed shop floor extensions.
Working capital effects tracked each quarter and reviewed in governance forums.

Chemicals — Multi-Region

Batch traceability and cost transparency by product family.

Adopted standard processes with a small, approved set of extensions.
Profitability analysis aligned to yield and mix with an operational variance loop.
Compliance reporting automated with an audit dashboard.

Utilities — Generation and Transmission

Funds, projects, and asset capitalization with complete evidence trails.

Standardized work breakdown structures; cutover ledger reconciled to opening balances.
Capital expenditure stage-gates tied to regulatory milestones and documented approvals.
Variance oversight strengthened and narrative improved for regulator submissions.

Snapshots describe adoptable patterns that organizations can implement without speculation or fabricated results.

5) Metrics and Signal Loops

Lead Indicators

Defect and backlog burn-down after deployment with owner and deadline.
Adoption by role measured as transactions per user and forum participation.
Change request approval cycle time and data quality score by domain.

Lag Indicators

Close duration and reconciliation exception trend.
Working capital performance and inventory turns.
Unit economics and return on investment by program track.

6) Common Failure Modes

Feature chasing: customizing before policy and decision rights are clarified.
Shadow spreadsheets: lineage broken by off-system reconciliations.
Ungoverned custom work: complexity without control or value justification.
Activation without adoption: celebrating go-live without run-state ownership.

7) Practical Artifacts

Chart of accounts and cost object blueprint with a decision map.
Extension value gate covering reports, interfaces, conversions, enhancements, forms, and workflows with policy references.
Data migration playbook with rules, ownership, reconciliation, and cutover evidence.
Cutover ledger template containing trial balances and documentation.
Benefits register with baselines, counterfactuals, and accountable owners.
