SAP S/4HANA Transformation for Small and Medium-sized Enterprises

More than an IT upgrade: The move to SAP S/4HANA transforms processes, control and operations – and requires an implementation that lasts the long term.

How we can support your SAP S/4HANA transformation

Our Services

Implement SAP S/4HANA from scratch (Greenfield)

When processes are to be rethought, systems harmonised and structures modernised, a reintroduction is the right way.

We accompany:

Target image definition and fit-to-standard workshops
Process design and organisational perspective
Introduction of SAP S/4HANA (Cloud or On-Premise)
Project structure, go-live and stabilisation

Our goal: A system that is soundly established from the outset.

Migration from SAP ECC to S/4HANA (Brownfield)

If an existing ECC system is fundamentally functional but technologically or strategically reaching its limits, a system conversion is worthwhile.

We support:

SAP ECC Analysis and Readiness Assessment
Custom Code Analysis and Cleanup
Data migration and interface testing
Tests, Cutover Planning and Operations Stabilisation

Our goal: A clean migration that does not jeopardise ongoing operations.

Selective Data Migration

If neither a pure conversion nor a complete restart is sensible, a selective approach can be the right way. Selected data and structures are adopted and specifically cleansed.

We support:

Evaluation of scope, data migration and target state
Planning, testing and cutover implementation
Operational stabilisation

Our goal: A viable compromise that reduces complexity while ensuring continuity.

Why switch to SAP S/4HANA now?

Many companies are asking themselves: „When is the right time to switch?“. The answer is: now – and for good reasons:

Support for older systems is expiring. Those who plan now decide for themselves. Those who wait decide under pressure.
S/4HANA brings speed. Real-time data instead of monthly reports. Decisions when they are needed.
Modern Fiori interfaces finally make SAP user-friendly. SAP that your employees will actually enjoy using.
Less manual work in analyses, more automation overview.
One system instead of ten workarounds. Less complexity, lower maintenance costs.

And above all: a stable foundation for the next ten years.

Structured for a Successful S/4HANA Transformation

Our Method

Every SAP S/4HANA transformation is different. However, successful projects follow a clear principle: first understand, then decide, then implement – with consideration for later operation.

We combine technical diligence with organisational clarity.

1. Understanding the starting position and system landscape

At the beginning, there is no concept of transformation, but a realistic look at what currently exists.

How is the system used today?
Where did in-house developments originate?
Which interfaces are critical?
How stable is master data and reporting?

We consider processes, system landscape and integrations in context, not in isolation.

Result:
A resilient view of complexity, dependencies and risks.

2. Check technical readiness and S/4HANA compatibility

Before an approach is decided upon, we check the technical prerequisites and effort drivers.

Typical content:

SAP Readiness Check and Simplification Items
Analysis of Custom Code and Modifications
Evaluation of Interfaces and Middleware
Data volume, archiving and performance
Role and authorisation concepts
Infrastructure and Hosting Options

Result:
Clarity on what is technically necessary and where unnecessary „legacy baggage“ would be carried along.

3. Define the transformation path

The appropriate path will be determined based on the starting position and readiness.

Greenfield – if processes are to be fundamentally re-established
Brownfield – if the existing ECC system is viable
Selective Data Migration – if a middle way seems sensible

Decision criteria

Original developments / modifications
Data Quality and History
Process alignment vs. retention
Time pressure, resources, operations
Target Image (Cloud / Hybrid / On-Prem)

Result:
A transformation approach that is justifiable in terms of content and technology.

4. Plan target architecture, data, and integrations cleanly

Many risks arise not from the core system, but from interfaces and data transfers.

That's why we plan early:

Target architecture and system roles
Integration scenarios with SAP and non-SAP systems
Master Data Governance
Migration strategy and cutover logic
Reporting and Analytics Target State

Result:
A technical and organisational target state that functions in everyday life.

5. Implementation, Testing and Validation

The implementation is carried out in a structured manner, with clear test stages and comprehensible validation.

Not just „technically runs“, but „functionally works“.

Typical focal points:

Sandbox conversions or prototypes help to identify risks early on.
Custom code is adapted or deliberately cleaned.
Data is being migrated and validated.
Processes are tested in terms of their functional aspects, not just technically clicked through.

Result:
A system that is tested for resilience before going live.

6. Go-live and stabilisation

The go-live is a controlled transition.

With clear cutover planning, defined responsibilities, and a structured hypercare phase, we ensure a stable transition of the system into operation.

The transformation has only truly arrived when processes are running in everyday life.

7. Operation, Stabilisation and Further Development

SAP S/4HANA is not a project state, but a platform.

After go-live, it's about stability, optimisation and targeted further development.

We accompany:

Stabilisation and Incident/Problem Management
Performance Tuning
Process optimisation and reporting
Release and Change Management
Extensions and Integrations (BTP, Add-ons, Tycom Solutions)

Result:
A stable system that can be further developed.

Frequently Asked Questions

What is the difference between migration and transformation?

A migration is often the technical switch to SAP S/4HANA. A transformation additionally encompasses processes, data, organisation, and stable operation. Crucial is not only the go-live, but a setup that sustains long-term.

Greenfield or Brownfield – how do you make the right decision?

This depends primarily on the condition of the SAP ECC system, the extent of custom developments, data quality, and the target state. We support the realistic assessment of options, including effort, risks, and operation.

How long does an SAP S/4HANA transformation take?

That depends on the starting point, system complexity, and organisational structure. Typical projects range from a few months to several phases. What’s crucial is less the duration itself, but rather realistic planning and a clean stabilisation in operation.

What happens to in-house developments and modifications from ECC?

In-house developments are assessed as part of the readiness and custom code analysis. Some can be adapted, much can be replaced by standard solutions or Fiori. The goal is a solution that remains maintainable in the long term.

How is ongoing business secured during the transformation?

Transformations happen almost always in parallel with day-to-day business. That's why we plan roles, responsibilities, test phases, and cutovers in such a way that critical processes are secured – including a hypercare phase after go-live.

Does Tycom also support stabilisation and further development after go-live?

Yes. SAP projects do not end with go-live. We provide support for stabilisation, maintenance, and further development – for example, in reporting, integrations, or extensions via SAP BTP and proprietary solutions.
