The NASA standard for models and simulations

The National Aeronautics and Space Administration (NASA) developed the Standard for Models and Simulations as an indirect result of the Space Shuttle Columbia Accident. During the post-accident investigations, some findings indicated that the incorrect application of a model, simulation, and/or analysis method can lead to incorrect decision making. The resulting standard is distinct from existing software standards in that it focuses on the reporting of M&S results and the assessed credibility of those results. As a first of its kind standard, it is openly distributed for assessment and comment. Discussions about the impetus for developing this standard and its use in critical decision-making provide a framework for the discussion of the requirements contained therein.
