Chapter 9: Best Practices Associated with Evaluating Damage Prevention Data

9.20 Results Are Quantified Against a Standardized Risk Factor

Practice Statement:

Results are quantified against a standardized risk factor. The risk factor considers a stakeholder’s exposure to potential damage. This risk factor may be based on factors such as the number of miles of line installed or the number of one call center notification tickets. For example, a risk factor may compare how many underground damages occurred in a certain time period versus the total number of notification tickets issued.
