Introduction

A Computerized Maintenance Management System (CMMS) or Enterprise Asset Management (EAM) system is essential software for modern maintenance operations. These systems centralize maintenance information, streamline workflows, and enable data-driven decision making that transforms maintenance from a cost center to a value driver.
