tools include not just codes, but also supporting data, databases, environments, and the associated validation and verification test results. Negotiating incentives to provide models, simulations, and data as contract deliverables will provide program managers and their integrated product team staff with insight into the design, engineering, manufacturing, and performance trade-offs in a way that is not available in current procurement schemes. It also provides a starting point on the path to establishing modeling and simulation as a method for ensuring that design requirements are met. These deliverables would lead to a reduced amount of validation testing, and thus lower overall cost and faster product delivery times.
