Productivity Tip 20 What is Preventive Maintenance?
Preventive Maintenance (or Preventative Maintenance) is a process in which we can prevent major failures of equipment by scheduling various activities to keep that equipment in peak condition. Here are five productivity gains that can be achieved if you adopt a Preventive Maintenance programme in your business or in your customer’s business.
Evolution of Maintenance Systems
Early Preventive Maintenance systems were manual in nature. These required the use of preventive maintenance forms and service sheets. Initially these related to maintenance events derived from actual historical breakdowns which provided a Mean Time Between Failure (MTBF) frequency. This provided a frequency for creating a 'Planned' Maintenance Event. However, with the introduction of computer technology the use of Preventive Maintenance software became the preferred way of managing this functional area. Evolution of this computerisation has extended the scope of a Preventive Maintenance process beyond simply 'Planned' Maintenance and can now include:-
Planned Event - These are Maintenance Events scheduled at a pre-defined date.
Predictive Event – Based upon predictions derived from Actual usage rather than time. (For example: 30000Km or 12 Months whichever comes first; copies; cycles).
Today Maintenance systems also include activities outside the original scope of simply maintaining Company 'Plant'. Examples are:-
To adequately cover this increased scope maintenance computer programs were enhanced to include:
Maintenance activities in Ostendo
Ostendo covers all the above Maintenance styles and also facilitates the automatic creation of a Customer Asset record and its maintenance schedule at the time a maintainable Item is sold to the Customer. Having created the Service schedule Ostendo also has the capability to send a reminder to the customer detailing impending maintenance activities. This can be in the form of a Letter, Phone, or email. Once the Service Reminder has been acknowledged and confirmed then it is included in Ostendo's Advanced Resource Scheduling function which can also include Resource Demands from all other areas of the business (Sales, Shop Floor Assembly Orders, Job Orders, etc). This scheduling function uses Critical Constraint Resource (CCR) criteria to schedule key personnel and equipment.
