Implementation Priority
The extent of the benefits that can be achieved depends on:
- Maintenance costs
- Any potential or existing capacity problems (e.g. in high growth areas)
- Age of assets
- Levels of service (reliability/production issues)
- Cost of service required.
For individual assets, the priority should be based on:
- Older assets with higher probability of failure
- High consequence or critical assets
- High cost, poor performing assets. These assets are normally at the lower end of their condition decay curves.
Assets can also be prioritized on:
- Poor performance (low availability/reliability)
- High unplanned maintenance cost (e.g. exceeds 15% of replacement cost)
- High consequence of failure (e.g. consequences exceed replacement cost)
- High unplanned to planned maintenance ratio (e.g. unplanned maintenance exceeds 50% of maintenance costs)
- High total maintenance costs (e.g. exceeds 20% of replacement value).
