How to Use TOGAF® Business Scenarios for Successful SAP S/4HANA Implementation
A detailed roadmap showing how TOGAF business scenarios guide the implementation of SAP S/4HANA.
What Is a Business Scenario in TOGAF®?
In TOGAF®, a Business Scenario is defined as a typical business pattern or story that captures how the business operates in a given context. It is used as a technique to clarify business requirements and link them to the architecture, so the scenario itself is not the goal but a means to make needs and value visible.
A Business Scenario includes the following key elements:
Target business processes and/or applications (or their combinations)
The business and technology environment in which they operate
People, organizations, and systems involved in execution (actors)
Expected outcomes, described as successful end states
A crucial point is that a Business Scenario should be SMART: Specific, Measurable, Actionable, Realistic, and Time-bound. By making scenarios SMART, they become a solid basis for defining architecture requirements and measuring the impact of the transformation.
The Role of Business Scenarios Across TOGAF® ADM
Within the TOGAF® ADM, a Business Scenario is not limited to a single phase; it acts like a “thread” that runs from the initial phases through business, application, and implementation planning. Because it consistently represents “requirements, value, and priorities”, a well-defined scenario in the early stages has a direct impact on the overall quality of Enterprise Architecture (EA).
How Business Scenarios are used in each phase:
Phase A (Architecture Vision)
Define representative Business Scenarios and use them as stories to explain to stakeholders why the architecture is needed.
Use them to agree on scope boundaries and priorities, such as which scenario to start with.
Phase B (Business Architecture)
Decompose the scenarios and use them as a starting point for modeling business processes, organizations, business functions, and business services.
By mapping scenarios to the value chain and end-to-end processes, the connection between strategy and operating model becomes explicit.
Phase C (Information Systems Architecture – Applications/Data)
For each scenario, identify required application services, data objects, and interfaces, and derive non-functional requirements such as performance and availability.
Phase D (Technology Architecture)
Translate each scenario into concrete platform requirements such as scalability, redundancy, and network characteristics.
Decide which Business Scenario is covered in which release and reflect this in the roadmap and transition architectures.
Use scenarios as anchors to manage traceability from scenario → requirements → architecture components → implementation.
Redefining TOGAF® Business Scenarios for SAP Implementation
In SAP implementation projects, it is effective to treat a Business Scenario not just as a set of process flow diagrams, but as the minimum EA unit that connects SAP standard capabilities to business value. This perspective allows discussions and decisions to be driven by value rather than by isolated functions.
For SAP implementation, a Business Scenario can be rephrased as: “A complete, end-to-end business story that describes how systems including SAP, together with organizations, processes, and data, interact to deliver a specific business value (for example, inventory reduction or shorter financial closing lead time).”
Within this description, the TOGAF® elements (processes, environment, actors, outcomes) can be mapped as follows:
Business processes / applications: End-to-end processes in SAP S/4HANA such as “Order-to-Cash” and “Procure-to-Pay”.
Business / technology environment: Global site structure, multi-currency and multi-language requirements, and existing legacy interfaces.
Actors: Sales, purchasing, finance, inventory management, external partners, and related systems.
Expected outcomes: KPIs and target values such as lead time reduction, improved inventory turns, and faster financial closing.
Why this matters in SAP projects:
Fit/Gap from a value perspective
Fit/Gap analysis can be conducted in units of business value instead of individual functions, making it easier to structure differences between SAP standard and current operations as well as required extensions or process changes.
Common language among stakeholders
Business, IT, and SAP vendors can discuss requirements based on shared scenarios, reducing omissions and misalignment.
Release planning and value realization
It becomes possible to visualize “which release will deliver which Business Scenario and how it will impact which KPIs” on the roadmap.
Hub of the EA repository
By linking process models, organization charts, application maps, data models, and interface lists around scenarios, consistency and traceability of Enterprise Architecture are significantly improved.
Practical Usage Examples in SAP S/4HANA Projects
Assume a SAP S/4HANA implementation viewed from an EA perspective. Below are concrete examples of how to use Business Scenarios in each ADM phase.
Example 1: Defining an “Order-to-Cash” Scenario in Phases A–B
SMART definition of the scenario:
Specific: Standardize the “Order–Shipment–Billing–Payment” process on S/4HANA for Japan and Asia sites.
Measurable: Reduce average lead time from order to payment from 10 days to 7 days.
Actionable: Use standard SD functionality as a baseline and redesign credit management, shipping conditions, and legacy system interfaces.
Realistic: Scope limited to key customers representing 80% of sales.
Time-bound: Achieve the KPI within six months after rollout.
In this way, the scenario is organized as a SMART scenario as recommended in TOGAF.
Expansion into Business Architecture:
Use the scenario as the axis to model the end-to-end Order-to-Cash process and related business functions/roles (sales, shipping, billing, credit management, and so on).
Explicitly capture issues within the scenario (for example, paper-based orders and double data entry) to visualize standardization and automation targets.
Fit/Gap and requirements definition:
For each step in the scenario, compare SAP standard processes with current processes and identify necessary extensions and process changes as requirements.
Tag each requirement with “which scenario and which step it supports” to maintain traceability in the EA repository.
Example 2: Designing Application/Data and Technology in Phases C–D
Application Architecture:
For each scenario, identify required SAP modules (such as SD, MM, FI) and surrounding systems, then define the interface structure.
For the “Order-to-Cash” scenario, clarify integration with CRM and warehouse systems as well as how billing data is posted to accounting.
Data Architecture:
Identify master data (customers, products, prices) and transactional data (orders, shipments, invoices, payments) handled in the scenario, and define requirements for data quality, integration, and master data governance.
Technology Architecture:
Derive scalability and availability requirements from transaction volumes and peak times for each scenario.
If there are constraints such as global access and latency, reflect them in decisions on regional landscape and network design.
Example 3: Migration and Release Planning
Release planning by scenario:
For example, plan to roll out SAP in Phase 1 focusing on “Order-to-Cash”, then add “Procure-to-Pay” and “Inventory Management” in Phase 2.
For each release, clarify the scenarios and expected KPIs to be delivered and secure stakeholder alignment.
Transition Architecture:
For each release, clarify which scenarios remain on legacy systems and which move to SAP, and design temporary interfaces and data migration strategies accordingly.
Communication with vendors and SI partners:
Business Scenarios become key materials that help vendors understand and explain solution value.
In proposal phases, it becomes easier to have concrete conversations such as “for this scenario, this template and accelerator will be applied, producing this impact.”
Key Takeaways for SAP and TOGAF® Practitioners
In TOGAF-based Enterprise Architecture, a Business Scenario is the story that connects business requirements, value, and architecture. In the context of SAP implementation, it works extremely well as a central axis for Fit/Gap analysis, release planning, and EA repository structuring.
If your SAP program has a long list of requirements but it is unclear “what this architecture is really for”, start by defining a set of representative Business Scenarios and reusing them consistently across ADM phases. Doing so will make it far easier to see a coherent EA-level end-to-end picture of your SAP transformation.
