One Call Center Facility Owner Excavator Locator Project Owner Designer

Practice Statement:

An effective damage prevention education program includes structured annual or biennial (every two years) measurement(s) to gauge the success of the overall program.

Practice Description:

Damage prevention education program effectiveness can be gauged in several ways. Consider the following examples:

  • Use of a direct-mail or telephone survey to effectively determine how one call center and/or member facility customers are hearing and recalling the damage prevention message.
  • Use of Arbitron Areas of Dominant Influence (ADI) boundaries to measure increases in one call center call volume and/or member facility owners/operators’ one call messages is also an effective measurement. For a given area, these can be compared against the money and resources used in that area for further indications of program effectiveness.
  • The collection and tracking of individual or collective facility owners/operators’ damage information from year to year is another outstanding method of measuring success, providing that other internal factors at a given facility owner/operator remain constant.
