Work Order

A work order is a formal document or digital record that authorises and tracks a specific maintenance task. It typically includes the asset identification, description of work required, priority, assigned technician, parts needed, safety requirements, and completion details. Work orders provide a structured workflow from request through approval, execution, and closeout.

Computerised Maintenance Management System (CMMS)

A CMMS is software that centralises maintenance information, automates work order management, and tracks the upkeep of physical assets such as plant, equipment, and fleet. It stores service history, schedules preventive tasks, and manages spare parts inventory. Organisations use a CMMS to move from reactive, paper-based maintenance to a structured, data-driven approach.

Mean Time to Repair (MTTR)

Mean Time to Repair (MTTR) measures the average time required to diagnose and fix a failed asset and return it to operational status. It includes diagnosis, sourcing parts, performing the repair, testing, and return to service, and is calculated by dividing the total repair time across all failures by the number of failure events in a given period. MTTR is a key input to availability calculations and is often tracked alongside Mean Time Between Failures (MTBF) to give a complete picture of asset reliability and maintainability. Some organisations distinguish between Mean Time to Repair (active repair time only) and Mean Time to Restore, also called Mean Time to Recover (the full elapsed time including waiting for parts, travel and administrative delays), as the broader measure often reveals improvement opportunities beyond wrench-time efficiency.

Corrective Maintenance

Corrective maintenance refers to repair or restoration work carried out after a fault, defect, or failure has been identified in an asset. It may be triggered by an operator report, a failed inspection, or an unexpected breakdown. Corrective tasks range from minor adjustments to major overhauls, depending on the severity of the issue.

Total Cost of Ownership (TCO)

Total Cost of Ownership (TCO) is a financial metric that captures all costs associated with owning and operating an asset over its entire lifecycle, including acquisition price, financing costs, maintenance and repair, fuel or energy, insurance, registration, operator costs, downtime costs, and disposal or residual value. TCO provides a comprehensive view of the true cost of an asset beyond its purchase price.

Field Service Management (FSM)

Field service management is the coordination of an organisation's resources, including technicians, vehicles, tools, parts, and information, to deliver maintenance, installation, inspection, or repair services at locations outside the organisation's own facilities. FSM encompasses the full service delivery lifecycle: customer or internal request, triage and prioritisation, technician dispatch, travel, on-site work execution, parts consumption, completion reporting, and invoicing or charge-back. Modern FSM platforms integrate scheduling optimisation, mobile workforce tools, asset and inventory management, customer communication, and analytics into a single system. Industries with large field service operations include utilities, telecommunications, HVAC, elevator and escalator maintenance, medical equipment servicing, and industrial equipment support. Key performance indicators for field service include first-time fix rate, mean time to service, technician utilisation, cost per service call, and customer satisfaction scores, all of which are driven by the quality of scheduling, the availability of parts and information, and the effectiveness of the mobile tools provided to technicians in the field.

Maintenance, Repair and Operations (MRO)

Maintenance, repair and operations (MRO) describes the supplies, spare parts, tools, consumables, and activities required to maintain and repair equipment, facilities, and infrastructure. MRO items, such as bearings, filters, lubricants, fasteners, and safety equipment, support production and operations but are not incorporated into the finished product. MRO is managed as a distinct category from raw materials and production inventory.
