Rolling out MES across many countries is hard. Each site has its own set of rules, tools, and working methods. A global plan must still fit local needs. That is the challenge. Many companies attempt to use a single MES setup across all locations. This often results in delays, confusion, and resistance from users. What works in one plant may not work in another. Language, regulations, and manufacturing workflows vary from country to country, and even within some cases, from plant to plant. For successful implementations and rollouts, it is crucial to establish a bridge between global objectives and local needs. It is necessary to plan, listen, and adjust throughout the process.

Additionally, support after the launch is just as important as the initial rollout. This study explores the factors that influence the success or failure of global Manufacturing Execution System (MES) projects. It is based on a real case from a worldwide manufacturer with strict rules and complex sites. This study examines the rollout of MES in various countries. It covers the steps, problems, and what leads to success.

The goal is to identify what helps people use it effectively and maintain consistency in system operation across sites. The findings support that both schools and companies learn how to scale MES in real-world settings. This can guide future projects in digital manufacturing. This study is based on a real case from a global manufacturing company. The company operates in a highly regulated, rules-based industry. It rolled out MES across many production sites. Each site required robust tracking, process control, and integration with ERP systems. The goal was to study how the rollout worked in practice. It examined problems, deployment time, user buy-in, system health, compliance, and integration. The study employed both numerical data and stories to provide a comprehensive picture. Data came from project documents, talks with IT staff, MES leads, and plant supervisors. Surveys and feedback were also taken from floor workers and rollout teams.

Results from different sites were compared after launch to assess their performance. The study found that global MES rollouts can work and lead to strong user adoption. However, success depends on local changes, good planning, and strong teamwork. After rollout, fine-tuning and addressing regional gaps remain challenging and require a clear focus. The study showed that MES rollouts can be completed in approximately three to nine eighth per site. This proves that a global setup is possible. However, success requires precise planning, strong control, and local adjustments. One plan will not work everywhere.

Good rollouts depend on more than just the tech. Require adequate planning, local support, and adaptable regulations. The study offers clear steps for future MES projects. It emphasizes the importance of post-go-live support, user training, and customized plans tailored to each site.
