Process Audit & Diagnostics

I am a System Analyst and Senior SAP consultant at EPAM Systems. When sponsors feel Order-to-Cash, Procure-to-Pay, or custom integrations are leaking value, I run structured audits to expose where the flow breaks and how to fix it. The goal: restore control, shorten lead times, and keep S/4HANA portable.

Audit focus areas

1. Order-to-Cash (O2C)

• Analyse order fulfilment stages from intake to billing, including ATP/aATP, pricing, delivery creation, and billing completion.
• Inspect backlog drivers: blocked deliveries, incomplete billing docs, idoc rejections, credit management holds.
• Map incident history to specific process steps and quantify revenue impact.
• Evaluate extension footprint (user exits, BAdIs, custom tables) for clean-core alignment and documentation.

2. Procure-to-Pay (P2P)

• Review sourcing, purchase order automation, goods receipt, invoice verification, and payment release.
• Identify manual interventions (parked invoices, GR/IR imbalances, unplanned delivery costs) and their root causes.
• Check vendor master governance, approval workflow design, and segregation of duties (SoD) risks.
• Validate how custom fields, forms, or partner add-ons impact compliance and audit trails.

3. Integration & custom developments

• Inventory interfaces across Idoc, AIF, PI/PO, Integration Suite, APIs, and event mesh.
• Assess logging, monitoring, replay, and idempotency patterns — highlight where observability is missing.
• Evaluate custom code quality, transport hygiene, and test coverage for high-change components.
• Confirm decision records (ADRs) exist for critical build vs. buy choices and platform selection.

Diagnostic toolkit

1. Process mining & logs — SAP application logs, CDS views, and change docs to trace actual process flows.
2. KEDB and incident clustering — group repeat issues by process stage, integration partner, or plant.
3. Code review matrix — catalogue enhancements, extensions, and wrappers with portability scoring.
4. Control heatmap — visualise SoD gaps, manual overrides, and compliance breakpoints.
5. Observability scan — measure alert coverage, runbook quality, and MTTR trends.

Engagement flow

1. Kick-off & scoping (Week 0-1)
   • Stakeholder interviews across business, IT, and operations.
   • Collect baseline metrics (OTIF, DPO, backlog age, automation rate).
   • Confirm data sources (logs, transport history, change docs).
2. Discovery & analysis (Weeks 1-3)
   • Run process mining queries, interface traces, and code reviews.
   • Catalogue findings in an audit backlog with severity, owner, and remediation options.
   • Validate hypotheses with frontline users and AMS teams.
3. Playback & prioritisation (Week 4)
   • Present heatmap of risks and opportunities by domain (O2C, P2P, Integration).
   • Align on remediation sprints: clean-core refactoring, observability rollout, control hardening.
   • Produce guardrails (ADRs, design briefs) so fixes stay portable and auditable.
4. Follow-through (Weeks 5+)
   • Pair with delivery teams to embed guardrails and prevention metrics.
   • Set up monitoring dashboards and MTTR/lead-time tracking.
   • Provide an executive scorecard for ongoing governance.

Outcomes to expect

• Faster cash conversion: fewer billing backlogs, smoother deliveries, cleaner returns handling.
• Stronger compliance: SoD, approval workflows, and audit evidence brought under consistent governance.
• Lower run-rate: reduction in repeat incidents, manual retries, and partner escalations.
• Portable architecture: clean-core remediation plans and integration guardrails ready for future programmes.

Working together

Use this audit when you suspect the process is slowing growth, when audit findings keep returning, or when custom code feels like a black box. I partner with AMS, product, and compliance leads to turn findings into measurable improvements.
