What Opex Consulting does

Opex Consulting Group is a Singapore-headquartered management consulting firm that delivers end-to-end digital transformation and operational excellence services to mid-market and enterprise manufacturers across Southeast Asia, Asia-Pacific, South Asia, and EMEA. The firm operates a two-division architecture — Training and Consultancy and Technology Solutions — and targets clients in verticals such as medical devices, steel, biofuel, oil and gas, and float glass. Its core technology offering is the OpexDX (Digital Transformation) platform, built on the proprietary ADD-IS five-pillar methodology (Assess, Design, Deploy, Integrate, Sustain), which orchestrates a People-Process-Technology approach to Industry 4.0 adoption. The OpEx APS Preactor advanced planning and scheduling platform functions as a sub-product within the Technology Solutions practice, and an "Ideal Factory" reference architecture spans CRM, CPQ, CAD/PLM/CAM, ERP, MES, APS, IIoT, predictive maintenance, warehouse digitalization, RPA, and real-time mobile dashboards. The firm is brand-agnostic, selecting best-fit hardware and software for each client to avoid vendor lock-in.

The company's go-to-market is enterprise field sales with direct client engagement, supplemented by content marketing (long-form articles, gated whitepapers) and event-driven thought leadership. Services are delivered by in-house consultant teams and sold through quote-based, custom-priced engagements with multi-year contracts; no public price list is offered. Geographic delivery is supported by three permanent offices — Singapore (HQ at 1 One North Crescent), Jakarta, Indonesia, and Penang, Malaysia — with stated project reach across 16 countries/regions. Opex is privately held, founder/management-led under Managing Partner/CEO Franklin Lim, with no disclosed external funding, parent entity, or institutional shareholders. Named customers include Intricon Pte Ltd, voestalpine HPM Pte Ltd, HiGi Biofuel (Philippines), and Banshing Industrial Pte Ltd, with engagements spanning Lean Six Sigma deployment, Industry 4.0 advisory, Lean SIRI assessments, S&OP, and customized training programs delivered in English and Bahasa Indonesia.

Core offering

Opex Consulting Group provides Lean Six Sigma training, operational excellence consulting, and brand-agnostic Industry 4.0 technology solutions to manufacturing and supply chain clients. Its core platform, OpexDX, accelerates digital transformation through the proprietary ADD-IS methodology (Assess, Design, Deploy, Integrate, Sustain) covering People, Process and Technology concurrently. The firm delivers services via two divisions: Training and Consultancy (certification courses, advisory, assessments, roadmaps) and Technology Solutions (Industry 4.0 building block deployment, including the OpEx APS Preactor advanced planning and scheduling platform).

Product overview

Opex Consulting Group operates a two-division, platform-plus-services architecture rather than a single unified product. The core offering is the OpexDX Platform, an integrated digital-transformation accelerator for manufacturing and supply chain industries built on the ADD-IS methodology (Assess, Design, Deploy, Integrate, Sustain) and the Lean Six Sigma foundation. Around this core platform sit two service divisions: Training and Consultancy (which delivers the Lean Six Sigma, Operational Excellence, Planning, Industry 4.0 Consultancy, Technical Skills, Soft Skills, Human Capital Development, Business Consultancy, and Assessment & Roadmap modules) and Technology Solutions (a brand-agnostic Industry 4.0 building-block practice). OpEx APS Preactor functions as a sub-product / Industry 4.0 building block within the Technology Solutions portfolio, providing advanced planning and scheduling. The OpexDX platform orchestrates the deployment, integration and sustainment of these building blocks, while the consultancy division prepares people, process and technology for adoption.
