Having covered the basics, it’s time to look at how to create a preventive maintenance schedule. In the section that follows, we will tell you more about how to schedule preventive maintenance.
Step 1: Assess inventory assets
Before you create your equipment preventive maintenance schedule, it’s highly advisable that you carry out an inventory of all your assets, big and small, expensive and less costly. This way, you will have a clear picture of which machines will require more work than others and which ones will be more costly to repair but are necessary for the overall functioning of the organisation’s production lines.
Step 2: Prioritise assets by maintenance needs
These can be identified not only by their high value or high repair costs but also by their crucial nature to the overall contribution to the functioning of your organisation. In short, they are your critical assets. In addition, they will most likely have failure modes that indicate when maintenance should be carried out. This is generally referred to as a criticality analysis.
Once you have identified these assets, you need to record the data so that you can prioritise these machines on a more frequent basis, as and when necessary. The factors for prioritisation will depend on the organisation in question as each one deals with different assets at different life stages of the asset.
Step 3: Identify preventive maintenance intervals
Once you have prioritised your assets, you will be in a better position to determine the different methods for scheduling maintenance tasks. For example, will they be time- or metre-based? For this purpose, you will need to look at the equipment manufacturer’s warranty and maintenance manuals as well as carry out a historical analysis of the timing when maintenance will be necessary.
You will also need to bear in mind that you shouldn’t over-maintain as this can be costly for the organisation, too. Ultimately, you want to achieve a balanced middle ground between under- and over-maintaining machinery so that you hit the sweet spot on an ongoing basis within an organisation defined by well-functioning machinery.
Step 4: Set recurring PM tasks
Unfortunately, many manufacturing facilities still use spreadsheets and paper-based methods to schedule PM tasks. However, in a fast-paced business environment, this is no longer feasible and that’s where automation comes in. To automate your maintenance schedule, the most modern, sophisticated and powerful solution involves using preventive maintenance scheduling software or computerised maintenance management system (CMMS) platforms.
Through this software, you can schedule work orders and maintenance tasks on time and even automate those related to repetitive tasks. What is more, depending on the type of CMMS software you choose, you can also notify your technicians via smart devices such as smartwatches, tablets or smartphones. This enables faster turnaround times, especially when you are managing multiple machines situated across different locations.
Step 5: Continually improve maintenance schedules
Over time, machines, operations and production all change. That’s why relying on a fixed PM schedule is not always the most reliable way to carry out your maintenance tasks. For this purpose, you need to constantly evaluate the effectiveness of your schedule and make small but lean adjustments for optimal performance. To help you determine whether you are on the right track, you may wish to monitor important metrics such as:
- Mean time between failure (MTBF)
- Planned maintenance percentage (PMP)
- Scheduled maintenance critical percent (SMCP)
- Preventive maintenance compliance (PMC)
- Overall equipment effectiveness (OEE)
- And others
With the reporting capabilities of the right CMMS platform at your fingertips, historical data can be quickly and easily made available to you through customisable dashboards. This not only makes reporting easier. It’s also a solid foundation for your preventive maintenance scheduling efforts.
