Why MES Projects Fail – and How to Avoid It

Implementing a Manufacturing Execution System (MES) is a strategic decision for any manufacturing company aiming to digitalize production processes, improve traceability, and boost operational efficiency. Yet, despite good intentions, many MES projects fail — or worse, they are completed but fail to deliver real value.

Let’s explore why this happens and how you can avoid it.

1. Lack of Clear Objectives

The issue: Many companies start an MES project without well-defined, measurable goals. “Digitalizing the factory” is a vision — not a strategy.

The fix: Begin with a detailed plan that includes specific and quantifiable goals, such as reducing scrap by 10%, achieving full traceability, or cutting downtime by 15%. Every goal should be linked to a clear KPI.

2. Poor Understanding of Current Processes

The issue: MES is implemented without a proper analysis of actual workflows. As a result, the system gets configured around theoretical processes, not how things really happen on the shop floor.

The fix: Conduct a thorough process assessment before selecting any technology. Involve operators, supervisors, and maintenance teams to get a complete and practical picture.

3. Lack of User Involvement

The issue: The project is led solely by IT or upper management, with minimal input from the people who will actually use the system every day.

The fix: Take a user-centered approach. Involve production staff early on, gather feedback, and invest in practical training. Engaged users are far more likely to adopt and support the system.

4. Over-Customization

The issue: The MES is heavily modified to meet every internal request, leading to long timelines, hidden costs, and difficult maintenance.

The fix: Choose a flexible MES that can be configured rather than rewritten. A good MES offers open APIs and smooth integration options — adapting to your processes without compromising stability.

5. No Gradual Rollout Strategy

The issue: Companies try to activate everything at once — traceability, maintenance, quality, scheduling, OEE. The result? Confusion and resistance.

The fix: Follow a modular, step-by-step rollout. Start with a pilot on one line or department. Measure results. Scale progressively. This approach builds confidence and reduces risk.

6. Inadequate Post-Go-Live Support

The issue: Once the system is live, the project team disappears and the internal staff is left to deal with problems on their own.

The fix: Work with a reliable technology partner that offers ongoing training, product updates, and responsive support. Go-live is only the beginning of the journey.

Conclusion

MES projects often fail not due to technology, but because of organizational and strategic missteps. With the right mindset, an experienced partner, and a collaborative approach, MES can become a powerful driver of growth, efficiency, and competitiveness.
