What is the difference between predictive maintenance and CBM?
Condition-based maintenance and predictive maintenance are both forms of proactive maintenance that occur before equipment breaks down. Predictive maintenance relies on precise formulas—often derived from historical data on equipment failure—in addition to sensor measurements to predict when an asset will fail.
|Condition-based maintenance||Predictive maintenance|
|Definition||A proactive maintenance strategy where assets are maintained on an as-needed basis (based on signs of impending equipment failure).||A proactive maintenance strategy where work is scheduled in the future based on historical data insights on equipment failure.|
|Triggers||Time intervals or meter readings.||
Predicted date of failure and/or other warning signs.
|Cost||Medium/high (startup cost)||High|
|Use case||Highly critical production assets with high repair and replacement costs.||
Assets with an unpredictable failure rate that require high-precision maintenance.
Condition-based maintenance software
1. Streamline the reporting process
Condition-based maintenance software provides a fast and easy way to aggregate condition monitoring data so you can create work orders and track the success of your CBM strategy.
Reports allow you to see how frequently an asset is maintained, how much it costs, and how much money is saved by using preventive maintenance. With all your data stored in one place, you can effectively manage work orders, purchase orders, inventory, and maintenance records — all of which are required for a successful preventive maintenance program.
2. Optimize the workflow
Create a set of standard maintenance procedures technicians can follow when dealing with complex assets. Even if these assets aren’t currently under a preventive maintenance plan, you can still minimize downtime and maintenance costs by preparing for the asset’s eventual degradation.
CMMS features help facilitate this process by providing quick access to maintenance logs for every asset, a spare parts management system that helps control inventory so you never run out of replacement parts and centralized information about each asset (OEM recommendations, fault patterns and maintenance procedures).
3. Manage scheduling
A CMMS automatically provides notifications to all concerned parties when a condition-based maintenance task is due, as indicated by sensors, meter readings, or historical data. Using Micromain's mobile technician app, maintenance workers can view information about the work order and provide status updates while working onsite or remotely.
A CMMS gives you insight into the following information:
- List of active corrective tasks
- List of tasks that still need to be scheduled
- Which technicians are assigned to cover which tasks
- Who is available to cover corrective tasks that still need to be scheduled
4. Create communication channels
Remember that condition-based maintenance doesn’t only concern the maintenance team. Employees who work with assets that are waiting to be repaired need to be updated on the progress of maintenance work.
For example, say the maintenance manager didn’t notify the line manager that a technician is coming. The technician would have to wait around until production stops or the space is clean and ready for him to start.
A mobile CMMS comes with a built-in chat function that makes it easy for managers to communicate with each other onsite, as well as push notifications that notify managers of important changes.
Although condition-based maintenance can be the proper maintenance strategy for certain types of assets and situations, it is not the best approach for all assets and situations. It can often lead to costly downtime, shortened life of assets, unsafe working conditions, and more.
An effective maintenance strategy should also include preventive and even predictive maintenance, and there is no better way of implementing preventive and predictive maintenance than with a CMMS.
