Risk Based Infrastructure Assessment. A. Antelman and A. Miller, US Navy
The Navy needs tools to objectively judge the value of one project against another. To do so, decision makers at multiple command levels must be able to analyze the operational risks and consequences of funding or deferring infrastructure sustainment, renovation and modernization (SRM) projects. Currently there is no standard methodology within the Naval shore establishment for determining infrastructure SRM priorities based on mission criticality from a "war fighter," operator or users point of view.
In response to this requirement, the Naval Facilities Engineering Service Center (NFESC) has developed the Mission Dependency Index (MDI). The intent was to create an Operational Risk Management metric that would relate buildings and other infrastructure to Navy missions. MDI is a measure used to describe the relative importance of infrastructure in terms of mission criticality. It does this by evaluating the impact to the mission if the function provided by the infrastructure is interrupted or relocated. MDI is reported on a scale of 1 TO 100 with 100 representing the highest mission importance.
MDI is a simple, yet meaningful methodology for determining the operational relationships between infrastructure and mission. It provides the Navy with mission criticality metric that is consistent across the Navy’s total SRM program. By identifying relative mission worth of infrastructure, MDI can be use to eliminate or reduce the priority of marginal projects. MDI provides Naval shore facilities managers with a new decision support tool for prioritizing SRM projects based on mission criticality.
The MDI has undergone its first round of testing at two Naval shore activities and the initial acceptance from the "war fighter," operator, and user community has been positive. This document introduces the MDI methodology, provides lessons learned from the two test sites, and provides recommendations for future development, test and evaluation.
