For Japanese manufacturers operating overseas production facilities, production management methods and systems often differ from one factory to another. At factories in Vietnam and other countries, Excel spreadsheets and paper-based reports may still be widely used, making it difficult for headquarters in Japan to obtain timely production information.
Addressing these challenges requires a structured approach to production data management, allowing headquarters and overseas factories to access consistent and reliable information.
One approach is to improve production data visibility by integrating a Manufacturing Execution System (MES) with existing business systems.
This article explores common challenges in overseas factory production management, how MES can support data visibility, and practical steps for improving coordination between headquarters and manufacturing sites.
01. Why Is Overseas Factory Production Management Challenging?
Manufacturers operating multiple overseas facilities may use different production processes, reporting formats, and management systems at each location.
Even when headquarters collects data from all factories, comparing performance accurately can be difficult if data definitions and reporting methods are inconsistent.
For example, one factory may define production output as the number of finished products, while another records the quantity processed at each manufacturing stage.
Therefore, effective data management requires more than collecting information. Manufacturers need to establish what data should be recorded, how it should be measured, and when it should be updated.
02. Three Common Challenges Between Headquarters and Overseas Factories
1. Delays in Production Reporting
When overseas factories prepare production reports in Excel and send them by email, headquarters may need to consolidate and process the information manually.
This creates a time gap between actual shop-floor operations and the information available to management, making it harder to identify production delays or operational issues promptly.
2. Inconsistent Data Definitions Across Factories
Production output, defect rates, and work-in-progress inventory may be calculated or measured differently across manufacturing sites.
Without standardized definitions, consolidating these figures can lead to misleading comparisons and inaccurate operational assessments.
3. Difficulties Integrating Existing Systems
Headquarters in Japan may use an ERP system, while overseas factories operate separate production management applications or Excel-based workflows.
When these systems are not connected, employees may need to enter the same information multiple times or transfer data manually between applications.
03. How Can MES Improve Overseas Factory Data Visibility?
MES manages manufacturing information such as production instructions, process progress, shop-floor performance, and quality records.
By connecting MES data with ERP and Business Intelligence (BI) tools, manufacturers can make relevant production information more accessible to both headquarters and overseas facilities.
| Management Area | Information Shared Across Locations |
|---|---|
| Production Progress | Planned quantities, actual output, and progress by manufacturing process. |
| Quality Management | Inspection results, defect quantities, and quality issues. |
| Inventory Management | Raw materials, work-in-progress inventory, and finished goods. |
| Equipment Operations | Equipment operating status, downtime records, and operating hours. |
For example, headquarters may use dashboards to compare production plans and actual output across factories, while local production teams access more detailed process-level information.
However, achieving real-time visibility depends on how data is collected on the shop floor, the availability of equipment connections, and the system integration environment.
04. Four Steps to Standardize Production Management Across Overseas Factories
Standardizing production management does not necessarily mean replacing every factory’s existing systems with a single platform.
A practical starting point is to identify the information that headquarters and each manufacturing site need to share, then determine how existing systems can support that requirement.
STEP 1 | Assess Factory Operations and Existing Data
Review production processes, reporting formats, existing applications, and data collection methods at each factory. Identify differences in data definitions and operating procedures.
STEP 2 | Define Common Production KPIs
Standardize the definitions of key indicators such as production output, defect rates, and inventory quantities. Clarify measurement units, reporting periods, and calculation methods.
STEP 3 | Plan MES, ERP, and Existing System Integration
Evaluate how production data can be exchanged while retaining existing ERP and production management systems where appropriate. Define integration methods, update frequency, and user access permissions.
STEP 4 | Roll Out the Solution Gradually
Begin with one factory or selected manufacturing processes. Validate data accuracy and usability in daily operations before considering deployment to additional locations.
Factories may manufacture different products using different equipment and processes. A shared data framework can support consistent reporting while allowing each facility to maintain operational workflows suited to its manufacturing requirements.
05. BAP’s MES and Manufacturing DX Services for Overseas Factories
BAP supports manufacturers in Japan and Vietnam with MES development, manufacturing digital transformation, and integration of existing business systems.
In a beverage manufacturing project in Vietnam, BAP implemented an integrated manufacturing system connecting MES, Laboratory Information Management Systems (LIMS), Computerized Maintenance Management Systems (CMMS), ERP, and Business Intelligence (BI).
For a Japanese steel pipe manufacturer in Vietnam, BAP conducted operational assessments, business analysis, and MES system design covering production records, work-in-progress inventory, quality management, and traceability.
Managing overseas manufacturing data requires consideration of both local factory workflows and the information needed by headquarters in Japan.
BAP evaluates existing systems and operational requirements to propose appropriate solutions for data collection, system integration, and production dashboards.
Facing Challenges Managing Production Data Across Overseas Factories?
From improving data sharing between headquarters in Japan and factories in Vietnam to production visibility and ERP integration, BAP helps develop MES and business systems tailored to manufacturing operations.
Conclusion
Overseas factory production management becomes more challenging when manufacturing sites use different reporting methods, data definitions, and systems.
Integrating MES with existing business systems can make production progress, quality, and inventory information more accessible to both headquarters and factory teams.
The goal is not necessarily to replace every factory’s systems, but to establish common management indicators and gradually improve data integration according to each facility’s operational needs.
