CMMS – Maintenance Glossary

A CMMS is of vital Importance for exercising control of all maintenance operations, budgets, stock, and personnel. The texts on our website offered detailed explanations of what an Idhammar MMS is capable of doing, and how best to configure and deploy it.

In order to clarify the meaning of some of the jargon you will come across, and for the avoidance of doubt, we’ve compiled this helpful glossary.


In the context of CMMS, an asset is a fixed, physical item of machinery, infrastructure or associated facilities used within the manufacturing plant or factory premises.

Asset Hierarchy

Asset hierarchy is a ranking of the assets (machinery). This ranking can be expressed in terms of the financial value of a machine, or its importance in the manufacturing process. Hierarchy information will include such items as: a unique reference, location, supplier, model number, specification, target performance, and cost centre.

Asset Register

An asset register is a listing of all maintainable assets held within the organisation. It includes all items of machinery, and certain fixtures such as storage racking. A CMMS asset register will include all physical items that require maintenance and servicing, whereas an asset register used for accounting purposes is a list of assets by their financial value.

Browser Based Maintenance

Browser Based Maintenance is a CMMS program that is held remotely (rather than being downloaded onto a computerised hard disk within the plant), and is accessible via the internet.


Computerised Maintenance Management Systems- software that enables engineers to enhance their maintenance practices, take control of plan assets and practice expert maintenance management.


To be in accordance with legislation, specification, and industry best practice

Condition Tracking

Condition Tracking is the real time monitoring and reporting of a programmable number of pieces of data relating to the performance of any asset. The data is used to predict and forewarn of asset malfunction or failure and impending problems that may impact productivity. As well as being an invaluable device for scheduling maintenance and servicing, it also holds calibration data, manages audit trails and facilitates compliance with HSE requirements.

Core CMMS Modules

The basic, essential, modules that comprise the heart of the Idhammar CMMS modular software including planned and preventative maintenance; work management, asset register and document management.

Equipment Down Time

The amount of time within any given period when an asset fails and needs to be services or replaced.

Idhammar Maintenance Dashboard

A maintenance dashboard is a real time graphical display of the performance parameters of a given production cycle or process. It can be displayed on an external screen for the benefit of the workforce and maintenance staff. Various dashboards can be configured and personalised to suit each user or plant and offer drill down facilities for detailed interrogation of data.  The datasheet can be found here.

Intuitive User Interface

Enabling the creation of standard maintenance jobs that can be related to similar assets and repeated on a pre-scheduled or real time basis according to actual readings.


Key Performance Indicators – the factors that lead to optimisation of production of any item or component

Lead Time

The time it takes for a product or service to be delivered from date of order.

Lean Maintenance

Minimising spare part stock, optimum deployment of maintenance labour resources, and maximum reduction of machinery down time. Lean maintenance is an essential component to achieving lean manufacture.

Maximised Assets

Machinery that is working at optimum efficiency with the minimum of down time.


Maintenance Management System – Idhammar’s own unique version of the generic CMMS – Computerised Maintenance Management System software.

Personal Development Records

Part of Idhammar’s maintenance personnel skills register which records the skills and certifications of each member of the maintenance team. It ensures the most appropriately qualified member of the team is allocated to the pertinent task.

Planned Maintenance

Planned maintenance may be either preventative or predictive. It is a maintenance or service that has been scheduled to take place.


Plant in CMMS terms refers to a manufacturing plant or factory premises. In other contexts plant can also include fixtures and machinery, but in CMMS these are usually referred to as assets.

Plant Assets

Machinery in manufacturing areas.

Pocket Maintenance

Pocket Maintenance is an aspect of Idhammar’s CMMS software that enables the use of hand held PDAs enabling maintenance engineers to access inspection schedules, capture and manage feedback, record meter readings, issue work order statements and check stock availability for key components necessary to service equipment on location .


Predictive Maintenance – maintenance schedules that are created to establish high levels of asset reliability and are mostly performed whilst the equipment is in service. The goal is to undertake maintenance activity before the assets loses optimum performance capability, therefore extensive Condition Monitoring is vital.


Preventive or ‘Preventative’ Maintenance – maintenance programs that are designed to prevent machinery assets from malfunctioning or breaking down by planning repairs, replacing components and servicing assets so that incipient failures can be detected or corrected before they occur or develop into major defects.

Reactive Crisis Management

Reactive Crisis Management takes place when a problem has been allowed to manifest itself. Best use of Idhammar’s MMS is designed to negate the need for reactive crisis management through proper deployment of PdM and/or PM

Regulatory Compliance

Metrics that are applied by outstanding agencies (including the HSE) that apply to the manufacture/production of goods and services and which must be seen to be met.


Reliability Centred Maintenance – the practice of developing and centring maintenance around component parts that are prone to failure, as well as maintaining those parts and seeking to develop a more reliable alternative.


Intelligent reporting modules that use the data captured to analyse and report on all aspects of maintenance management helping to maximise the efficiency of production, minimise downtime, and help to avoid having to employ reactive crisis management


Service Level Agreements – Idhammar MMS helps to ensure SLAs are honoured by improving and tracking the reliability of machinery, minimising down time and improving machinery efficiency.


Total Productive Maintenance- a zero tolerance approach towards breakdowns by maximising equipment effectiveness. Achieved by maintaining equipment throughout its life, involving planning, design and maintenance departments and actively involving employees at all levels in the promotion of the importance of TPM.

Work Management

A module that allows planned maintenance work to be scheduled and managed to maximise efficient use of labour and to minimise down time. This module utilises both paper based works orders or wirelessly transmitted PDA data

Workload Planner

Facilitates the selection of any given number of programmed maintenance operations which interrogates the system to ensure sufficient materials and labour resources are available. If there is a conflict, Workload Planner can suggest alternative dates when sufficient resources are expected to be available.
