Maintenance Operations Management commonly refers to the coordinated planning, execution, monitoring, and improvement of maintenance activities on production assets and infrastructure. It focuses on keeping equipment, facilities, and supporting utilities in a condition that allows manufacturing operations to run as intended, while documenting work in a traceable and auditable way.
What it includes
In an industrial and regulated manufacturing context, Maintenance Operations Management typically covers:
- Maintenance planning and scheduling: Defining preventive, predictive, and corrective work; prioritizing jobs; scheduling technicians and downtime windows.
- Work execution: Performing inspections, repairs, calibrations, and replacements according to defined procedures or work instructions.
- Work order management: Creating, approving, dispatching, and closing work orders, including capturing labor, parts, tools, and time.
- Asset and equipment management: Maintaining structured records of assets, hierarchies, locations, histories, and criticality.
- Spare parts and MRO materials coordination: Linking maintenance work with storeroom inventory, reservations, and usage tracking.
- Condition and performance monitoring: Using inspections, sensor data, or analytics to trigger or optimize maintenance actions.
- Compliance and documentation: Recording maintenance histories, calibrations, and changes to support audits, traceability, and internal policies.
- Continuous improvement: Analyzing failures, recurring issues, and maintenance KPIs to refine strategies and standard work.
Maintenance Operations Management is often supported by a Computerized Maintenance Management System (CMMS) or Enterprise Asset Management (EAM) system, and it may be integrated with MES, ERP, and quality systems.
Relation to ISA‑95 and operations management
Within the ISA‑95 model, Maintenance Operations Management is one of the functional areas at Level 3 (Operations Management), alongside production, quality, and inventory operations management. In this context it focuses on how maintenance work is requested, planned, dispatched, executed, and reported, and how that information is exchanged with higher-level business systems and lower-level control systems.
What it is not
- It is not the same as real-time control of machines or process variables (which belongs to control systems at ISA‑95 Level 2).
- It is not limited to emergency repair; it includes preventive, predictive, and reliability-centered strategies.
- It is not only an IT function; it combines people, processes, and systems on the shop floor and in supporting departments.
Operational use
In day-to-day manufacturing, Maintenance Operations Management appears as:
- Work orders generated from equipment alarms, operator requests, inspections, or schedules.
- Coordinated production and maintenance downtime planning between MES and maintenance systems.
- Documented maintenance and calibration records tied to specific assets, batches, or lots when needed.
- Standardized procedures for critical equipment, with revision control and training requirements.
- KPIs such as mean time between failures (MTBF), mean time to repair (MTTR), and maintenance-related downtime tracking.
Common confusion
- Maintenance Operations Management vs. Production Operations Management: Production Operations Management focuses on executing manufacturing orders, managing recipes, and tracking production. Maintenance Operations Management focuses on sustaining asset availability and reliability. They are related and often integrated but address different workflows and data.
- Maintenance Operations Management vs. Asset Management: Asset Management is broader, often covering asset lifecycle, investment, and financial considerations. Maintenance Operations Management focuses on the operational activities performed on those assets.
