|Mission Dependency Index (MDI)
An operational risk metric for assessing the criticality of facilities and describing their relative importance based on the owners mission (ie., strategic plan) for it's entire portfolio of facilities.
The index provides a series of qualifiers to indicate the impact, or consequences, if a facility is destroyed (force majeure), sustains significant physical deterioration, or becomes non-functional.
The index asks the following types of questions about each facility in order to establish levels of mission criticality:
The index provides a series of qualifiers to indicate the impact or consequences if a facility is destroyed or non-functional: Critical; Relevant; Significant; Moderate; Low.
The following table provides a summary of the key steps in developing an MDI framework for an asset portfoliol
Levels of Mission Criticality
Listed below are the three tiers of mission criticality contemplated by the Mission Dependency Index:
For example, post-disaster facilities would be rated as critical.
MDI Correlation with FCI
When the MDI is cross referenced with the Facility Condition Index (FCI) each facility will fall into one of the following four quadrants:
Application within the MUSH Sector
For example, in a civic/municipal portfolio, the three tiers of the
MDI may be deemed as follows:
Group 1: “Mission-Critical” Facilities
Mission critical facilities are typically kept at a high operating standard where the facility condition index (FCI) is below 5%.
