246 - The 3 Ways to Structure a Quality Management System (Centralized vs. Federated vs. Decentralized)

Most discussions about One QMS focus on harmonization.But before deciding whether a single global Quality Management System is the right approach, it's worth understanding the three primary ways organizations structure a QMS.In this episode, I compare centralized, decentralized, and federated (hybrid) Quality Management System models, including the trade-offs of each in terms of ownership, standardization, flexibility, governance, and decision-making.We also walk through how the document hierarchy typically differs across each model—from the Quality Policy and Quality Manual to standards, SOPs, work instructions, and records—and discuss why governance often has a greater impact on success than the operating model itself.Timestamps00:00 Why "One QMS" Is Trending01:33 The Three Primary QMS Models01:50 Centralized QMS02:01 Decentralized QMS02:28 Federated (Hybrid) QMS03:50 Comparing the Document Hierarchy04:14 Centralized Document Structure05:04 Decentralized Document Structure05:22 Federated Standards, SOPs, and Governance06:50 The QMS Tree: Philosophy, Governance, and Execution08:20 Why Governance Matters More Than the ModelSubhi Saadeh is a quality professional, consultant, auditor, and trainer who specializes in drug-device combination products, medical devices, pharmaceutical quality systems, supplier quality, and lifecycle management.
