ABSTRACT
As complexity continues to increase in modern systems development, performance requirement derivation in Defence materiel acquisition projects continues to present challenges. Overspecification introduces technical risk that can lead to project cost and schedule blow-outs. Insights into precise thresholds for system requirement performances can be difficult to ascertain through expert judgement. Operational analysis involves the modelling and simulation of the Defence materiel platform’s operational scenarios. The most challenging scenarios drive system performances, understood in the context of the combinations of systems working together to achieve operational effects. Such modelling and simulation provides insights into the capabilities of interest to Defence Service customers, and is useful for decision-making, trade studies and design negotiations. This work describes two such examples of operational analysis modelling and simulation used in a recent large and complex Defence materiel acquisition project for the derivation of system performance requirements and the facilitation of trade studies and design negotiations.
