TQM

What TQM does

TQM Consultants Co. Limited is a Hong Kong-headquartered management consultancy firm founded in February 1994 by Prof Ir Dr Aaron W. K. Tong. The firm delivers advisory and training services across quality management, operational efficiency, energy management, health and safety, sustainability, ISO certification, and information security, serving enterprise and government clients in Hong Kong and mainland China through a Wan Chai headquarters and a Shenzhen regional office. TQM has completed over 9,200 projects across 35 industries and claims a 70% share of HKSAR Government and Public Sector Management System Consultancy engagements, with a client roster that includes Airport Authority Hong Kong, Water Supplies Department, CLP Power, Siemens, Bank of China (Hong Kong), Marks & Spencer, Sands Resorts Macao, Tung Wah Group of Hospitals, and Zhejiang Supor.

The service portfolio is anchored by proprietary methodologies including Subtractive Quality Assurance (-QA), Act-N-Achieve© LEAN Total Solution, and the SPR Success Model, alongside established frameworks such as DMAIC and LEAN Six Sigma belt training (White, Yellow, Green, Black). TQM operates as a B2B professional services firm with direct, sales-led engagement: consulting is delivered on-site at client locations or at its training center, with project-based, quote-based pricing for consulting and per-participant fees for training programs (e.g., HK$8,000 per participant for the 4-day LEAN Six Sigma Green Belt course). The firm holds flagship affiliations with the American Society for Quality (ASQ), UNESCO's World Institute of Sustainable Development Planners (WISDP), and Corporate Coach U, and partners with CEPREI under China's Ministry of Industry and Information Technology for information security services.

Revenue is generated exclusively through professional services fees from consulting engagements and training programs. The company is privately held with founder-led management and no disclosed external investors, funding rounds, acquisitions, or divestitures. Growth has historically been organic, driven by long-tenured government and enterprise relationships, repeated engagements across 35 industries, and the addition of new practice areas such as ESG and corporate sustainability, cybersecurity, and asset lifecycle management.
