Introduction to Mission Utility

A performance assessment measures how well the system meets its quantitative goals and requirements
– Engineering oriented

Mission Utility is the quantitative expression of how well the system meets its overall mission objectives
– User oriented — what will it do for the warfighter or the victim? Provide feedback for the mission design Provide quantitative information for the decision-making community • Should we buy an ORSSat or buy more UAVs? The space system doesn’t matter — the warfighter doesn’t care about “how,” only “what” the system can do for them They don’t want another piece of equipment that will serve mostly as something to put under the wheels of the truck when it gets stuck The issue is, What can Responsive Space do for the warfighter or for people who need help Ultimately, ORS is not about launch systems or spacecraft. It’s about what we can do to help the warfighter or the cop in New Orleans, at low cost, by tomorrow morning (or, better, this afternoon). That’s what Mission Utility is intended to measure.

The Need for Mission Utility Analysis for ORS

A key issue in the ORS debate is whether and to what extent Responsive Space systems have sufficient utility to warrant the funding required
