Defining a Multi-decade Executable Program The Science and the Art An executable program requires balancing several (sometimes competing) constraints: Technical Feasibility Fiscal Affordability Stakeholders’ Interest Horizon Acceptable Risk International/Private Sector Engagement Political Realism Across Several Administrations Technology ready now or soon Use limited/common elements, assess affordability early. Land in 2030’s Test systems incrementally Create alignment early Demonstrate progress and relevance
