Uptime

The fourth edition of Uptime introduces an updated and expanded framework for achieving sustainable reliability and asset performance in an increasingly complex, data-enabled operating environment. Building on the proven foundation established by earlier editions, this new edition extends the original Uptime Pyramid of Excellence beyond maintenance best practices alone, positioning reliability as a strategic organizational capability that supports operational excellence, risk reduction, and long-term business performance. Rather than focusing solely on technology adoption, Uptime fourth edition emphasizes the integration of leadership, culture, work management, precision maintenance, reliability engineering, and data-enabled decision-making into a coherent operating model. The book presents a practical roadmap that guides organizations from reactive maintenance toward proactive, precision, and ultimately strategic maintenance through four stages of maturity: stabilize, control, optimize, and innovate. Updated throughout with modern practices and contemporary examples, the fourth edition incorporates advances in condition monitoring, analytics, digital workflows, Evidence-Based Asset Management (EBAM), and Precision Maintenance, while reinforcing the enduring principles that underpin reliability success. Written for maintenance and reliability professionals, plant managers, operations leaders, and asset managers, the fourth edition of Uptime combines practical guidance with strategic perspective to help organizations improve asset performance, strengthen workforce capability, and achieve sustainable uptime in today’s evolving industrial environment.
