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).
