What is a Computerised Maintenance Management System (CMMS)?
A Computerised Maintenance Management System (CMMS) is software used to plan, schedule, track and manage maintenance activities for equipment, machinery and other physical assets.
It provides a central system for managing maintenance work orders, preventive maintenance schedules, asset information, spare parts and maintenance histories.
CMMS software is widely used in manufacturing, utilities, oil and gas, transport, facilities management and other industries where equipment reliability and maintenance performance are important.
By bringing maintenance information and activities together, a CMMS helps maintenance teams coordinate work, reduce unplanned downtime and maintain a clearer picture of asset condition and maintenance requirements.
Why is a CMMS Important?
Maintenance teams need accurate information about equipment condition, outstanding work and planned servicing to keep assets operating reliably.
When maintenance activities are managed through paper forms, spreadsheets or disconnected systems, it becomes harder to prioritise work, track recurring faults and ensure inspections or servicing are completed on time.
A CMMS helps businesses:
- Plan and schedule preventive maintenance
- Manage maintenance work orders and priorities
- Reduce unplanned equipment downtime
- Track asset maintenance histories
- Improve spare parts and inventory management
- Support safety and regulatory compliance
- Monitor maintenance costs and performance
By providing greater visibility into maintenance activities, a CMMS helps teams move away from reactive approaches towards more structured and proactive maintenance management.
What Does a CMMS Do?
A CMMS brings together the information and processes needed to manage maintenance work.
Maintenance teams can use the system to create work orders, assign tasks, schedule servicing and track the status of maintenance activities.
Asset information, including equipment specifications, locations and maintenance histories, can be stored centrally so technicians and planners can access relevant details.
Many CMMS platforms also support spare parts management, maintenance reporting and performance measures such as Mean Time Between Failures (MTBF) and Mean Time to Repair (MTTR).
For example, a CMMS may generate a preventive maintenance work order for a production machine, assign it to a technician and track when the work is completed.
This helps maintenance managers understand what work is outstanding, which assets require attention and how maintenance activities affect equipment availability.
CMMS vs EAM: What’s the Difference?
A Computerised Maintenance Management System and Enterprise Asset Management (EAM) software are closely related, but they have different areas of emphasis.
A CMMS primarily focuses on managing maintenance activities, including work orders, servicing schedules, spare parts and maintenance histories.
EAM generally covers a broader range of asset lifecycle processes, from acquisition and installation through operation, maintenance and eventual replacement or disposal.
For example, a CMMS may manage the maintenance schedule and repair history of a production machine, while an EAM system may also support decisions about the machine’s lifecycle costs, performance and eventual replacement.
The distinction is not absolute. Many modern CMMS platforms include wider asset management functionality, while EAM systems typically provide extensive maintenance management capabilities.
The most important consideration is whether the software supports the maintenance and asset management processes required by the business.
CMMS vs Work Execution Layer: What’s the Difference?
Although a CMMS and a Work Execution Layer both support maintenance operations, they have different areas of emphasis.
A CMMS primarily helps maintenance teams plan, schedule and manage work. It provides visibility into maintenance requirements, work orders, asset histories and the resources needed to complete activities.
A Work Execution Layer focuses on how individual maintenance tasks are carried out. It connects technicians with the instructions, checks and information they need while capturing evidence of what happens during the work.
For example, a CMMS may schedule a preventive maintenance inspection and assign it to a technician. A Work Execution Layer can guide the technician through the inspection, capture measurements and photographs, and document any faults identified.
Some CMMS platforms already include mobile applications, digital checklists, operator guidance and evidence capture. The distinction therefore depends on the capabilities of the particular system rather than a fixed boundary between the two technologies.
The important consideration is whether maintenance teams have both the tools to manage their workload and the guidance needed to complete tasks consistently.
Why Might Maintenance Teams Need Both?
Even when a CMMS is in place, some maintenance activities may still rely on paper instructions, separate checklists or manual reporting.
A work order may be marked as complete without consistently capturing the measurements, inspections or evidence needed to understand exactly what was done.
A Work Execution Layer can help address this gap by providing structured digital guidance and capturing information during task execution.
When appropriately integrated, work orders and asset information from a CMMS can support frontline tasks, while completed job reports, inspection results and identified issues can contribute to maintenance histories and wider operational reporting.
This creates a clearer connection between maintenance planning and the work carried out, helping teams improve consistency, traceability and asset reliability.
How WorkfloPlus Complements CMMS
WorkfloPlus provides a Work Execution Layer that helps maintenance teams carry out inspections, servicing, repairs and compliance checks consistently.
Technicians can follow step-by-step digital instructions on mobile devices, tablets, desktops or supported smart glasses, with access to the latest approved procedures.
Photographs, measurements, timestamps, signatures and other evidence can be captured directly within each process. Issues identified during maintenance can also be documented, creating instant job reports and a traceable history of completed work.
WorkfloPlus can connect with wider maintenance and business systems through supported integrations and APIs, allowing relevant information to support existing maintenance processes where integrations are configured.
Rather than replacing a CMMS, WorkfloPlus complements maintenance management software by strengthening the connection between work orders, frontline execution and the operational data generated during maintenance activities.
