The strategic planning and creation of test scenarios for the Missile Defense Agency (MDA) All Digital System Level Simulations and Hardware-in-the-Loop (HWIL) test events is a lengthy and arduous endeavor. In some respects the difficulties and time required are understandable. There are a large number of stakeholders with a wide variety of perspectives, objectives and priorities. However, while a tremendous amount of coordination is required, the practices are also fraught with inefficiencies. The time consuming challenges of requirements-based scenario design will significantly benefit from rigor in the specification and control of common data sets. In addition, capturing the knowledge of subject matter experts to automate manual design processes has the potential to greatly increase effectiveness and quality of Scenario Generation resulting in streamlined creation, redesign and validation of scenarios.
