Why is RBI important?

A Risk Based Maintenance (RBM) approach determines the most economical use of maintenance resources with the end goal of minimizing any risk of a failure. Assets that have a greater risk and consequence of failure are maintained and monitored more frequently while assets that carry a lower risk are subjected to less stringent maintenance monitoring.

The first step of RBM is to identify your high risk assets and plot them into a simple risk matrix:

RBM Risk Matrix

The second step involves developing a maintenance strategy, focusing on the orange area in the risk matrix as those assets make up the highest risk of lost productivity and safety if they fail.

Risk Based Maintenance is important because:

  1. It identifies problems before they happen, which will minimize downtime because maintenance can be planned
  2. When maintenance is planned, you can avoid ‘reactive maintenance’ which has many overhead costs, more equipment downtime, higher costs for parts and shipping, and more time lost responding and diagnosing the equipment.
  3. Safety improves because equipment brakes down less
  4. Risk Based Maintenance extends the useful lifecycle of assets
  5. Contributes positively to the reputation of companies because the negative impact of equipment failure is far reaching down the supply chain

Unplanned downtime is a silent killer. Market benchmarks indicate that unplanned maintenance typically costs three to five time more than when it is planned.

The Cost of Downtime

Adopting a Risk Based Maintenance approach provides a systematic approach to determine the most appropriate asset maintenance plan which when implemented will minimize the risk of asset failure. Avoiding asset failure will have a positive effect on the ROI of your assets, safety, avoiding unplanned downtime, reputation, and your bottom line.
