Planning an ERP rollout?
Define your ERP requirements →Executive Context
One of the most common mistakes SMEs make during ERP planning is either under-defining requirements or overengineering them.
- Under-definition leads to poor vendor fit and missing capabilities
- Overengineering leads to unnecessary complexity, higher costs, and delayed implementation
The goal is not to capture every possible feature, but to define clear, practical requirements aligned with real business processes.
When to Use This Guide
Use this guide if:
- You are planning ERP implementation
- You are preparing for vendor evaluation
- You want to avoid scope creep
- You need clarity on system requirements
Expected Outcomes
- Clear and structured requirement definition
- Reduced complexity and overengineering
- Better vendor alignment
- Faster and smoother implementation
Phase 1: Start with Business Processes (Not Features)
Focus on how your business operates.
Key Activities
- Identify core processes (sales, procurement, finance, inventory)
- Map current workflows
- Identify pain points and inefficiencies
- Highlight process variations
What to Avoid
- Starting with feature lists
- Copying generic requirement templates
Deliverables
- Process maps
- Pain point summary
Gate Criteria (Phase Approval)
- Core processes identified
- Pain points clearly documented
Phase 2: Define Functional Requirements Clearly
Translate processes into system needs.
Key Activities
- Define required system behaviors
- Identify key transactions and workflows
- Specify reporting needs
- Prioritize requirements (must-have vs nice-to-have)
Best Practice
- Keep requirements simple and outcome-focused
Deliverables
- Functional requirement document
- Priority matrix
Gate Criteria (Requirement Clarity)
- Requirements aligned with processes
- Priorities defined
Phase 3: Avoid Overengineering
Keep scope practical and manageable.
Common Overengineering Areas
- Excessive customization requirements
- Trying to automate every scenario
- Over-detailed specifications
How to Avoid
- Focus on standard processes
- Limit customizations
- Plan phased enhancements
Deliverables
- Simplified requirement scope
- Customization guidelines
Gate Criteria (Scope Control)
- Scope is realistic
- Customization minimized
