MRO Supply Chain Excellence: The Practical Playbook for Reliability, Inventory, Procurement, Working Capital, and Digital Transformation

MRO is more than purchasing parts and managing a storeroom. It is an operating system.

Every maintenance organization depends on having the right material, in the right place, at the right time—without tying up unnecessary working capital or creating layers of purchasing complexity.

MRO Supply Chain Excellence gives operations, maintenance, procurement, reliability, materials, and supply chain leaders a practical framework for connecting asset reliability, inventory, sourcing, storeroom operations, suppliers, maintenance execution, technology, and financial performance.

Rather than treating MRO as a collection of disconnected transactions, Glenn Pierce shows how to manage it as an integrated operating system—one that balances service, cost, cash, reliability, and risk.

Inside, you’ll learn how to:

• Build a reliable MRO data and master-data foundation


• Identify and manage critical spares without overstocking


• Reduce excess and obsolete inventory while protecting equipment uptime


• Improve sourcing, supplier performance, and total cost of ownership


• Connect maintenance planning with material readiness


• Optimize storerooms, vending, kitting, repairables, and point-of-use inventory


• Measure MRO performance with meaningful operational and financial KPIs


• Apply analytics, automation, and AI without automating bad processes


• Build a practical 90-day roadmap for MRO transformation

The book also addresses integrated supply, VMI, outsourcing models, global logistics, repairable management, resilience, digital MRO, AI-enabled workflows, business-case development, and transformation governance.

Throughout the book, practical examples, decision rules, diagnostic questions, KPI frameworks, and implementation guidance help readers move from theory to action.

The included MRO Excellence Companion Toolkit extends the book with working tools such as an MRO maturity assessment, critical-spares matrix, supplier scorecard, KPI guide, sourcing-wave planner, 90-day transformation plan, and MRO business-case calculator.

Written from an operator’s perspective, MRO Supply Chain Excellence is designed for plant managers, maintenance and reliability leaders, procurement professionals, supply chain executives, storeroom and materials teams, finance leaders, technology professionals, consultants, and transformation leaders who want to improve performance without sacrificing reliability.

Turn MRO from a cost center into a strategic operating advantage.
