How to Use TOGAF® Compliance Assessment in SAP S/4HANA Implementation

Introduction

For Enterprise Architects involved in SAP implementation projects, TOGAF® Compliance Assessment is not merely a design review checklist. It is a governance mechanism that visualizes gaps between the target architecture and actual implementation, controls exceptions, and steers the project back on track.

In S/4HANA programs—despite adopting a Fit-to-Standard approach—deviations frequently emerge due to local requirements, legacy constraints, and site-specific conditions. By embedding Compliance Assessment at key milestones, Enterprise Architects can connect architectural intent with execution, transforming SAP projects into enterprise-wide transformation initiatives rather than isolated ERP deployments.

What is TOGAF® Compliance Assessment?

In TOGAF®, Architecture Compliance Review (or Compliance Assessment) evaluates how well projects or solutions conform to agreed architecture principles, standards, guidelines, and target architectures.

Its purpose is not just to verify compliance, but to:

• Identify gaps
• Understand root causes
• Define conditions for exception approval

This makes it a practical governance tool rather than a theoretical framework. It is also positioned as a core deliverable in Architecture Governance, typically including:

• Scope of assessment
• Evaluation criteria
• Compliance status
• Risks
• Remediation actions
• Exception approvals
• Final decision

This structure is highly applicable—and even more critical—in large-scale SAP programs.

Why It Matters in SAP Programs

In SAP implementations, the clean architecture envisioned during planning often erodes during design, build, and deployment phases.

Common issues include:

• Increase in custom developments despite standard capabilities
• Persistence of local data interfaces despite integration strategies
• Expansion of company-specific exceptions within global templates

Compliance Assessment transforms these issues from informal concerns into structured architectural discussions aligned with EA principles.

Importantly, it should not be treated as an audit. Unlike audits, which are retrospective, Compliance Assessment is proactive—intervening during design and implementation to guide decisions and manage exceptions.

What to Evaluate in SAP Context

To make Compliance Assessment effective in SAP projects, TOGAF® concepts must be translated into SAP-specific evaluation criteria across four architecture domains.

Business Architecture

Evaluate alignment with global business processes.

Key focus:

• Fit-to-Standard vs differentiation decisions
• Gap analysis for core processes (Order-to-Cash, Procure-to-Pay, Plan-to-Produce)
• Justification and impact of deviations
• Future harmonization potential

---

Application Architecture

Assess application landscape centered around S/4HANA.

Key focus:

• Clear roles of MES, PLM, WMS, EDI, BI systems
• Avoidance of functional overlap with S/4HANA
• Defined roadmap for legacy systems

Retaining legacy systems may be practical short-term, but increases long-term complexity.

---

Data Architecture

Focus on master data standardization.

Key focus:

• Consistency of material, customer, BOM, and cost data
• Defined data ownership and governance
• Data quality and migration standards
• Alignment with MDG/MDM strategies

Without data harmonization, SAP integration benefits remain limited.

---

Technology Architecture

Evaluate technical standards and integration approaches.

Key focus:

• API-first integration vs file-based interfaces
• Authentication and audit mechanisms
• Monitoring and infrastructure standards
• Management of temporary solutions and their sunset plans

---

When to Apply Compliance Assessment

Compliance Assessment should be conducted iteratively at key project phases:

• Planning Phase
  Evaluate alignment with EA roadmap and transformation goals
• Fit-to-Standard / Design Phase
  Validate gap justification and template integrity
• Implementation Phase
  Check compliance of extensions and integrations
• Deployment Preparation Phase
  Assess data quality, operational readiness, and open exceptions

Each review should function as an architectural decision point, with outcomes such as:

• Go
• Conditional Go
• No-Go

Automotive Tier-1 Example

In automotive Tier-1 SAP programs, Compliance Assessment is particularly valuable due to structural complexity:

• OEM-specific requirements (EDI, ASN, Kanban)
• Plant-specific production models
• Tight integration with MES and PLM
• Global rollout and M&A challenges

Example scenario:

A Tier-1 supplier deploys a global S/4HANA template across Japan, Thailand, and Mexico.

• Japan follows standard processes
• Mexico requires sequence delivery adaptations
• Thailand retains tight MES integration

Without Compliance Assessment, local optimizations accumulate, resulting in fragmented systems despite a common S/4 platform.

Key evaluation points:

• Is localization truly a competitive necessity?
• Are system responsibilities clearly defined?
• Are exceptions formally approved with timelines and convergence plans?

---

Practical Tips for Enterprise Architects

To make Compliance Assessment effective:

• Translate principles into actionable criteria
  (e.g., limit add-ons to regulatory or competitive needs)
• Do not aim for zero exceptions
  Instead, ensure exceptions are documented, approved, and time-bound
• Integrate assessment results into governance systems
  Link with EA repositories, PMO processes, and roadmap decisions

Ultimately, the role of an Enterprise Architect in SAP programs is not to enforce perfect compliance, but to manage deviations while preserving transformation integrity.
