Operational Proof

Validated by Manufacturing Leaders

Real perspectives from plant directors, quality vice presidents, and operations heads who have executed transformation programs alongside OpexCG.

"OpexCG did not just drop software on us. Their practitioners spent weeks on our shop floor re-engineering our batch workflows before digitalizing the batch record. The result was zero compliance deviations on our next regulatory audit."

VP of Global Quality & Regulatory
Class II/III Medical Device Manufacturing, Batam
100% Digital Batch Records (Zero Audit Findings)

"The SIRI assessment conducted by OpexCG revealed critical blind spots in our milling throughput that generic IT consultancies missed. Their technical roadmap gave our board the exact confidence needed to commit to a multi-plant Industry 4.0 rollout."

Director of Operations & Supply Chain
Southeast Asian Flour Milling Conglomerate
SIRI Tier-3 Certification & Predictive Maintenance Roadmap

"With SlingX, OpexCG bridged complex Epicor Kinetic custom business logic directly to our frontline technicians. Work order lead times were compressed by 40% without destabilizing our ERP core."
