What is a computerized maintenance management system CMMS?
A computerized maintenance management system (or CMMS) is software that helps maintenance teams keep a record of all assets they are responsible for, schedule and track maintenance tasks, and keep a historical record of work they perform.
Where do you install a CMMS?
There are two common places where CMMS software runs: On a computer at the client’s business or on the web.
When a business is responsible for running its own CMMS, it is called an on-premises CMMS. The benefit of this kind of installation is the user has full control over network access to the CMMS server and complete data privacy (relevant for defence contractors, for example). The drawbacks are that this type of CMMS implementation is expensive and complex. The IT department has to constantly look after the server, backups must be done by the maintenance team, and the software can quickly get out of date if updates aren’t installed regularly.
When the CMMS runs online, it is called a cloud-based CMMS. Here, the CMMS provider takes care of all the IT, hosting, security, and backups for the system, and the software can be accessed through any computer with an internet connection and web browser. Another strength of a cloud-based CMMS is that the software updates automatically, so you’re always using the latest version. Make sure to subscribe to a cloud-based CMMS that lets you export the information in your current system, so that you can migrate it if needed.Type your paragraph here.
What is preventive maintenance (PM)?
Preventive maintenance (or preventative maintenance) is maintenance that is regularly performed on a piece of equipment to lessen the likelihood of it failing. Preventive maintenance is performed while the equipment is still working, so that it does not break down unexpectedly.
Preventive maintenance is planned so that any required resources are available.
The maintenance is scheduled based on a time or usage trigger. A typical example of an asset with a time-based preventive maintenance schedule is an air-conditioner which is serviced every year, before summer. A typical example of an asset with a usage-based preventive maintenance schedule is a motor-vehicle which might be scheduled for service every 10,000km.
Preventive maintenance is more complex to coordinate than run-to-failure maintenance because the maintenance schedule must be planned. Preventive maintenance is less complex to coordinate than predictive maintenance because monitoring strategies do not have to be planned nor the results interpreted.
Assets suitable for preventive maintenance include those that:
Unsuitable applications for preventive maintenance include those that:
Advantages of preventive maintenance
Planning is the biggest advantage of preventive maintenance over less complex strategies. Unplanned, reactive maintenance has many overhead costs that can be avoided during the planning process. The cost of unplanned maintenance includes lost production, higher costs for parts and shipping, as well as time lost responding to emergencies and diagnosing faults while equipment is not working. Unplanned maintenance typically costs three to nine times more than planned maintenance. When maintenance is planned, each of these costs can be reduced. Equipment can be shut down to coincide with production downtime. Prior to the shutdown, any required parts, supplies and personnel can be gathered to minimize the time taken for a repair. These measures decrease the total cost of the maintenance. Safety is also improved because equipment breaks down less often than in less complex strategies.
