Embarking on a journey to SAP S/4HANA is like renovating your home. You have two primary options: start fresh with a new design or renovate your existing space. Let’s explore these approaches in a relatable way.
Greenfield Approach: Building a New Home
What It Is: Imagine demolishing your old house to construct a brand-new one tailored to your current needs and preferences.
When to Choose It:
- You desire a complete overhaul of your business processes.
- Your current system is outdated and hindering innovation.
- You’re planning to adopt cloud solutions like SAP Ariba.
Real-Life Example: A manufacturing company decides to implement SAP S/4HANA to streamline operations and integrate with modern cloud applications. They choose the Greenfield approach to build a system that aligns with their future goals.
Considerations:
- This approach is less common, with only 14% of companies opting for it.
- It requires more effort and resources.
Brownfield Approach: Renovating Your Existing Home
What It Is: Instead of tearing down your house, you renovate and upgrade it to meet modern standards while preserving its structure.
When to Choose It:
- Your existing system is still functional and meets most of your needs.
- You want to retain historical data and customizations.
- A quick transition with minimal disruption is desired.
Real-Life Example: A retail company has been using SAP ECC for years and has customized it to fit their operations. They choose the Brownfield approach to upgrade to SAP S/4HANA, preserving their customizations and data.
Considerations:
- This is the most popular approach, with 44% of companies choosing it.
- It allows for a smoother transition with reduced project time.
Hybrid Approach: Combining the Best of Both Worlds
What It Is: A blend of Greenfield and Brownfield approaches, allowing you to start fresh in some areas while retaining existing systems in others.
When to Choose It:
- You have multiple systems and need a phased approach.
- Certain departments require a complete overhaul, while others can be upgraded.
Real-Life Example: A multinational corporation operates in various regions with different systems. They implement the Hybrid approach, upgrading some regions while starting fresh in others to align with local needs.
Considerations:
- This approach is chosen by 42% of companies.
- It offers flexibility but may require careful planning and execution.
Making the Right Choice for Your Organization
Choosing the right approach depends on several factors:
- Business Objectives: What are your goals?
- Current System Landscape: What systems are in place?
- Resources Available: Do you have the necessary resources?
Decision-Making Guidance:
- Define your business needs.
- Build a business case.
- Develop a strategy using methodologies like SAP Activate.
Enterprise Architecture Tools:
