Original Equipment Manufacturer (OEM)
GM of Operations
OEM (original equipment manufacturer) refers to the company that designs and builds the original machinery, vehicle or component, whose specifications govern warranty, parts compatibility and recommended service intervals.
An Original Equipment Manufacturer (OEM) is the company that designs and produces an asset or component in its original form. In asset management, OEM refers to the manufacturer whose specifications, service intervals, and approved parts lists govern how equipment should be maintained. OEM documentation, including service manuals, parts catalogues, and warranty terms, forms the baseline for maintenance planning and compliance.
Why it matters
Following OEM-recommended service intervals and using approved parts protects warranty coverage and ensures equipment performs as designed. Deviating from OEM specifications without documented justification can void warranties, increase failure rates, and create liability if an incident occurs. OEM data also sets the starting point for maintenance schedules that teams refine over time with operational experience.
How MapTrack helps
MapTrack stores OEM service intervals, parts lists, and documentation against each asset record, ensuring maintenance teams follow manufacturer guidelines and can demonstrate compliance during warranty claims.

Frequently asked questions
Why should maintenance follow OEM recommendations?
OEM service intervals and procedures are based on the manufacturer’s engineering data, testing, and failure analysis. Following them ensures the equipment operates within its design parameters, maintains warranty coverage, and meets any regulatory requirements that reference manufacturer standards. Organisations may adjust intervals based on operating conditions, but should document the rationale for any deviation.
What is the difference between OEM and aftermarket parts?
OEM parts are manufactured by or to the specification of the original equipment maker. Aftermarket parts are produced by third-party manufacturers as compatible replacements. OEM parts typically carry the manufacturer’s warranty backing, while aftermarket parts may be less expensive but can vary in quality. For safety-critical components, OEM parts are generally the lower-risk choice.
How should OEM documentation be managed for a large asset fleet?
Store OEM manuals, parts lists, and service bulletins digitally against each asset record in your asset management platform. Link OEM service intervals directly to the preventive maintenance schedule so that reminders are generated automatically. When the OEM issues updated service bulletins or recalls, apply them to the relevant assets and update the maintenance plan accordingly.

Spare Parts Management
Spare parts management is the process of planning, procuring, storing, and issuing replacement components and consumables needed to maintain and repair assets. It involves determining which parts to stock, setting minimum and reorder quantities, managing supplier relationships, and ensuring parts are available when needed without carrying excessive inventory. Effective spare parts management balances availability against holding costs.
Preventive Maintenance
Preventive maintenance (PM) is a proactive maintenance strategy in which assets are serviced at predetermined time or usage intervals to reduce the likelihood of failure. Tasks may include inspections, lubrication, filter changes, calibrations, and component replacements. PM schedules are typically based on manufacturer recommendations, regulatory requirements, or historical failure data.
Service History
Service history is the chronological record of all maintenance, repairs, inspections, and modifications performed on an asset throughout its lifecycle. A comprehensive service history includes dates, descriptions of work, parts used, technician details, costs, and supporting documentation such as photos or test certificates. It serves as the permanent maintenance biography of an asset.
Resource Scheduling
Resource scheduling is the process of allocating available labour, tools, equipment, materials, and facilities to planned tasks within defined time periods to maximise utilisation and meet operational targets. In maintenance and field service contexts, resource scheduling involves matching technician skills and availability to work orders, ensuring that required parts and tools are available at the right location, sequencing tasks to minimise travel time and idle periods, and balancing workloads across teams and shifts. Effective resource scheduling requires accurate estimates of task duration, up-to-date information on resource availability, visibility into work order priority and dependencies, and the ability to reschedule dynamically when priorities change or emergencies arise. Advanced scheduling tools use constraint-based algorithms to optimise schedules across multiple variables simultaneously. The weekly scheduling cycle typically begins with a planning meeting where the maintenance planner and scheduler review the ready backlog, confirm resource availability, and build a schedule that targets 90 per cent or higher schedule compliance.
Site Induction
A site induction is a structured orientation process that familiarises workers, contractors, and visitors with the specific hazards, safety rules, emergency procedures, and operational requirements of a worksite before they commence work or enter designated areas. In Australia, WHS Regulations require PCBUs and principal contractors to ensure that all persons entering a construction site or other high-risk workplace are inducted with information relevant to their safety. A comprehensive site induction covers site layout and access routes, emergency assembly points and evacuation procedures, hazard-specific controls (e.g. overhead work, mobile plant, confined spaces), PPE requirements, permit-to-work procedures, reporting obligations for incidents and hazards, and any site-specific rules such as speed limits, exclusion zones, or drug and alcohol policies. Inductions may be site-specific (covering the unique characteristics of one location) or general (covering company-wide safety standards). Digital induction platforms have largely replaced paper-based sign-in sheets, enabling workers to complete inductions on their own devices before arriving on site, reducing delays at the gate and creating searchable records of who has been inducted, when, and for which site.
