A risk-informed approach is developed and demonstrated to consolidate five existing program assessment metrics to develop a unified metric that simultaneously considers the relative importance of each. These metrics are used to objectively evaluate new technologies and analysis tools designed to improve aviation safety. This allows for a meaningful and unbiased evaluation and comparison of NASA's Aviation Safety Program (AvSP) technologies. The resulting model is referred to as the Composite Program Assessment Score (CPAS). The CPAS includes five existing metrics; Technical Development Risk, Implementation Risk, Fatal Accident Rate, Safety Benefits and Cost, and Safety Risk, which were previously defined and quantified by different sources. The CPAS involves the scaling and combination of these individual metrics. The CPAS is based on a weighted sum model and an additive value theory model. The resulting metrics allow for an overall comparison of all AvSP products in the portfolio. Knowledge elicitation sessions were held with three different Subject Matter Experts (SMEs): a pilot, a NASA program manager of technical integration, and a NASA product manger. Selected scenario analyses from the SME knowledge elicitation sessions for the two models are presented.
