Other acquisition uses of simulation are emerging in engineering, manufacturing, and test and evaluation. All this is happening around the analysis community. Consider the negative aspects of the current state of modeling and simulation in the Department of Defense. Most of our current simulations are old, hard to evolve, and do not use modern software practices. They are usually stand-alone simulations, with no interoperability and no reuse.
Old simulations tend to be too expensive to maintain and operate.
Old simulations are also generally not verified, validated, and accredited, and are not well-coordinated during their development. Simulations will be ubiquitous, and will be used extensively and beneficially. They will be embedded in every phase of support tools for acquisition. The good news also involves improved cooperation across DoD, an emerging consensus, a roughly common vision. Modeling and simulation applications span multiple functional areas.
