Uptime

The 4th Edition of Uptime modernizes the world’s most trusted maintenance excellence framework for the realities of the digital age. While preserving the proven three-layer Uptime Pyramid of Excellence—Leadership (foundation), Essentials (systems), and Choosing Excellence (disciplined practices)—this edition brings the framework forward with new tools, new technologies, and new expectations facing today’s maintenance organizations.

Where earlier editions established a robust and practical approach to maintenance management, the 4th Edition integrates the advancements now reshaping the field, including:

• Evidence-Based Asset Management (EBAM)

• AI-assisted predictive maintenance

• Sensor-enabled condition monitoring

• Mobile and digital workflows

• Data quality standards for CMMS/EAM systems

• DOE-backed Precision Maintenance

• Updated RCM logic for modern operations

This edition retains the clarity and structure that made Uptime a bestseller, while adding practical, technician-focused methods aligned with contemporary work environments. This book equips frontline maintenance teams, supervisors, planners, and reliability practitioners with a practical, adoption-ready framework for achieving reliability excellence. It aligns the original Uptime Pyramid with modern digital practices and provides actionable guidance on:

• Leadership behaviors that build a culture of reliability

• Systems and processes required for consistent maintenance performance

• Disciplined practices such as RCM, proactive maintenance, precision maintenance, and RCFA

• Converting evidence into action through a structured Work Identification process.
