How do you determine the criticality ranking of assets for replacement planning under asset management?

• A. Rank by alphabetical order of asset ID.
• B. Rank by color coding only.
• C. Use risk scoring considering likelihood of failure and consequence, asset age, failure history, redundancy, and replacement cost.
• D. Randomly select assets.

Answer: (C)

Use a risk-based, data-driven scoring approach to rank assets for replacement. This means assigning a risk score to each asset that combines the likelihood of failure with the consequences if failure occurs, and then ordering assets from highest to lowest risk to guide replacement planning. The score should be informed by practical factors such as how old the asset is, its failure history, whether there is redundancy or backup capacity in place, and the cost to replace or rehabilitate it. Assets that are old and prone to failure, whose failure would severely disrupt service and for which replacement is expensive, will rank higher and be prioritized. Relying on alphabetical order, color coding alone, or random selection doesn’t reflect actual risk or service impact, so those methods don’t support effective, defensible decisions about where to invest limited resources. A data-driven risk ranking aligns with asset management goals of maintaining reliable service while optimizing lifecycle costs.
