Project Overview
A mid-size Japanese auto parts manufacturer based in Aichi Prefecture, with approximately 500 employees and three production facilities, approached BCT Global to modernize their manufacturing operations. The company supplies precision components to major Japanese automakers and needed to maintain their competitive edge in an increasingly data-driven industry.
The Challenge
The client's manufacturing operations relied on a legacy Manufacturing Execution System (MES) that was over 12 years old. Quality control processes were still paper-based, and there was no real-time visibility across their three factory floors. This created several critical problems:
- A 15% defect escape rate due to delayed quality reporting and manual inspection logs
- Production managers had no real-time view of equipment performance, leading to reactive (rather than predictive) maintenance
- Monthly reporting took 2 weeks to compile manually from spreadsheets across three facilities
- Data silos between factories made it impossible to optimize production scheduling across sites
- Growing pressure from OEM customers to provide digital traceability for every component
The client had previously attempted an internal digitalization project, but it stalled due to lack of specialized IoT and cloud engineering resources. They needed a dedicated team that could work alongside their existing IT staff without disrupting ongoing production.
Our Solution
BCT Global deployed a lab-style dedicated team of 8 engineers—including 2 IoT specialists, 3 full-stack developers, 1 cloud architect, 1 data engineer, and 1 bilingual project manager based in our Tokyo liaison office. The project followed an agile methodology with 2-week sprints and weekly demos to the client's manufacturing leadership.
Our approach was divided into three phases:
- Phase 1 — IoT Infrastructure (Months 1-4): Installed 200+ IoT sensors across three factory floors to monitor equipment vibration, temperature, cycle times, and output quality in real time. Connected sensors to AWS IoT Core for centralized data ingestion.
- Phase 2 — Dashboard & Analytics (Months 4-9): Built a custom React-based dashboard providing real-time OEE (Overall Equipment Effectiveness) monitoring, predictive maintenance alerts, and quality analytics. The dashboard supported both Japanese and English interfaces.
- Phase 3 — Cloud Migration & Integration (Months 9-14): Migrated legacy MES data to AWS (Lambda, RDS, S3), integrated with the client's existing SAP ERP system, and implemented automated quality traceability reports for OEM customers.
Throughout the project, all sensitive production data was handled in compliance with APPI (Act on the Protection of Personal Information) regulations. BCT Global's ISO 27001 certification provided the client with confidence in our information security practices.

Results & Impact
Within the first quarter after full deployment, the client saw a 40% reduction in unplanned equipment downtime thanks to predictive maintenance alerts. Monthly reporting that previously took 2 weeks was reduced to real-time dashboards accessible from any device. The defect escape rate dropped from 15% to 6%, and the client achieved full ROI within 8 months of the project's completion.
The success of this project led to a Phase 2 engagement, where BCT Global is now developing AI-powered quality prediction models using the historical sensor data collected during Phase 1.
"BCT Global's team integrated seamlessly with our factory operations. Their bilingual project manager understood both our technical requirements and the nuances of Japanese manufacturing culture. The fact that they are ISO 27001 and ISO 9001 certified gave us confidence from day one, especially when handling our proprietary production data under APPI compliance."
