What Are the Key Risks in ERP Implementation?
Here are the top 22 ERP risks and challenges that can harm your business operations and brand reputation. But don’t fret about it, we have also provided solutions for ERP risk management. Let’s take a closer look at each one.
1. Lack of Buy-in
Lack of buy-in from stakeholders is one of the most common ERP risk factors. When the leadership team, management, or end-users are disengaged or skeptical, ERP implementation stalls, and resistance builds. Without collective enthusiasm, the new ERP system may become underutilized or rejected entirely.
How to Avoid a Lack of Buy-in?
- Engage executives and departmental heads early to champion the initiative.
- Conduct workshops and presentations highlighting the key advantages of the ERP solution.
- Create a communication plan that shares wins and progress transparently.
- Empower employees in every business unit to act as local advocates.
How to Monitor Buy-in?
| Metric | Measurement Method | Target Threshold |
|---|---|---|
| Stakeholder Engagement | Surveys, workshop attendance | ≥80% positive response |
| Executive Sponsorship Level | Number of active executive sponsors | At least 2-3 sponsors |
| User Adoption Rate | System login and active usage | ≥75% usage within 3 months |
2. Change Management
Change management refers to how smoothly employees transition to new business processes and workflows in the implementation process. According to research by Prosci, projects with effective change management are seven times more likely to meet objectives. Conversely, resistance, confusion, or insufficient change adaptation capacity leads to delays and reduced system effectiveness.
How to Avoid Change Management Risks?
- Develop a formal change management strategy aligned with project phases.
- Deliver comprehensive, role-specific training early and post-launch.
