What are the essential steps for a successful ERP change?
Changing an ERP (Enterprise Resource Planning) system is one of the most critical decisions for any company. When executed well, it improves efficiency, reduces costs, and increases the company’s ability to grow. When it fails, it can compromise entire operations.
This guide presents the essential steps to ensure a successful ERP implementation, with a focus on the reality of companies operating in Portugal.
1. Define clear business objectives
Before looking at any software, it is essential to answer one question: why change the ERP?
Typical objectives include:
- Improving financial control
- Integrating fragmented systems
- Increasing operational efficiency
- Supporting growth or international expansion
2. Map current processes (and identify gaps)
A common mistake is to replicate old processes in a new system.
- Map current processes
- Identify inefficiencies
- Eliminate redundancies
- Define future processes (to-be)
3. Involve stakeholders from the start
- Management (decision-making and strategic vision)
- Operational teams (actual users)
- IT (integration and security)
4. Choose the right ERP (not the most famous one)
- Industry fit
- Scalability
- Ease of use
- Integration capabilities
- Local presence and support in Portugal
5. Choose the implementation partner
- Industry experience
- Implementation methodology
- Proven success cases
- Post go-live support capability
6. Plan the data migration
- Clean up legacy data
- Standardize information
- Define what should be migrated
- Perform consistency tests
7. Define the implementation approach
- Big Bang (everything at once)
- Phased (by modules or departments)
- Parallel (old and new systems running simultaneously)
8. Invest in user training
- Practical training
- Simple documentation
- Continuous support
9. Test, test, and test again
- Functional testing
- Integration testing
- Testing with real users
10. Prepare go-live and post-implementation support
- Contingency plan
- Dedicated support team
- Performance monitoring
- Quick adjustments in the first weeks
