The Reality of the Thailand Local MES Implementation Project (2)

Date : 23-07-2026

In the last article, we introduced the fundamentals of Manufacturing Execution Systems (MES).

In this follow-up, we will explore the practical realities of MES implementation projects, particularly in Thailand. We hope this article provides useful insights for organizations considering or planning an MES deployment.

Why Is MES Implementation Challenging in Thailand?

Most manufacturers recognize the importance of MES. However, turning that understanding into a successful implementation is often far more challenging than expected. In Thailand, companies frequently encounter a set of challenges that differ from those typically seen in Japan.

1. Heavy Reliance on Individual Expertise in Shop Floor Operations

Many manufacturing sites in Thailand still depend heavily on the experience, intuition, and know-how of skilled operators. As a result, operational procedures are often not fully standardized.

When companies attempt to introduce MES to improve process visibility and standardization, they often discover that organizing and documenting existing operations becomes a major project in itself.

Common examples include:

• Work instructions that either do not exist or no longer reflect actual operations
• Quality inspections managed on paper, resulting in inconsistent record-keeping
• Defect causes that rely on individual judgment and are not systematically recorded

These situations are far more common than many organizations initially expect.

2. IT Literacy and Training Challenges

MES implementation is not simply about deploying software. Its success ultimately depends on how effectively it is adopted and used on the shop floor.

However, several factors can hinder adoption, including :

• Limited familiarity with PCs, tablets, or handheld terminals among operators
• Resistance to data entry and system-based workflows
• Multilingual environments involving Thai, English, and Japanese

Without careful planning, these challenges can lead to one of the greatest risks of any MES project: a system that is implemented but rarely used.

This is particularly evident in multinational manufacturing environments, where insufficient attention to user experience (UI/UX) design and operator training can significantly reduce user adoption and prevent organizations from achieving the expected business benefits.

3. Difficulties Integrating with ERP Systems and Production Equipment

An MES serves as a bridge between systems, processes, and equipment. Therefore, integration with surrounding systems is a critical component of any implementation.

In practice, organizations often face obstacles such as:

• Incomplete or poorly maintained master data within ERP systems
• Production equipment lacking data collection interfaces
• A large number of legacy machines in operation

As a result, system integration frequently requires more time, effort, and budget than originally anticipated.

In Thailand, many factories operate a mix of second-hand equipment and machines from multiple manufacturers, making standard integration approaches insufficient or impractical.

4. Project Governance and Organizational Alignment

MES implementation is not only an IT project—it is also a business transformation initiative.

Project success is heavily influenced by factors such as:

• Differences between headquarters-driven policies and local operational realities
• Misalignment between IT and manufacturing departments
• Insufficient involvement of shop floor personnel

One of the most common pitfalls occurs when a template designed by headquarters in Japan is applied directly to operations in Thailand without adequate localization. In many cases, the result is resistance from local teams and a system that fails to deliver meaningful value.

Key Success Factors : Practical Lessons from the Field

Based on our experience supporting MES implementation projects in Thailand, several best practices consistently contribute to successful outcomes.

1. Start Small and Scale Gradually

Rather than attempting a full-scale rollout from day one, organizations should begin with areas where benefits can be demonstrated quickly, such as:

• Traceability management
• Production data collection
• Inventory and warehouse operations

A phased approach allows organizations to achieve early wins, build confidence, and reduce implementation risk.

2. Define Requirements from the Shop Floor Up

An MES should not be implemented simply because the technology is available.

Before defining system requirements, companies should first visualize, understand, and streamline their actual operational workflows. The system should support business processes—not the other way around.

---

3. Prioritize Multilingual Support and Ease of Use

Support for Thai language interfaces is essential. Equally important is designing a user-friendly system that operators can learn quickly.

Intuitive, icon-based interfaces and simplified workflows can significantly improve user adoption and long-term operational success.

4. Engage Shop Floor Leaders Early

Successful MES projects require strong involvement from key personnel on the production floor.

By engaging supervisors and operational leaders from the early stages of the project, organizations can foster a sense of ownership and encourage users to view the MES as their system rather than an externally imposed tool.
