SBA is an acquisition process in which DoD and industry are enabled by robust, collaborative use of simulation technology that is integrated across acquisition phases and programs. SBA allows the optimization of system performance versus total ownership cost (TOC) by early and continuing collaborative exploration of the largest possible trade space: across all of a system's life cycle activities, within and among multiple government and commercial organizations, across professions and disciplines, and up through system of systems mission area perspectives. SBA ensures a faster time to field through increased concurrency, tighter decision cycles, more efficient and effective testing, and a reduction in costly fixes for problems discovered late in the acquisition cycle. Application of SBA provides for a lower total ownership cost of individual systems via lower personnel and material costs, and from the standards-based reuse of information and software to minimize their cost.
