Abstract: This paper introduces a procedure to assess the credibility of models and simulations (M&S) as a group activity based on NASA’s new standard for M&S NASA‐STD‐7009. The Delphi method, which is characterized by iterative surveys with controlled feedback, was selected to implement the assessment. The proposed procedure is expected to address the issues in the M&S assessment related to a high level of required expertise and group decision making. An actual credibility assessment study using the proposed procedure on an M&S platform referred to as SpaceNet has been carried out by ten panel members through a two‐round Delphi. The study concluded that the overall credibility of SpaceNet version 1.3 was between the development level and production level. The variances of the assessments in the second‐round survey were significantly reduced compared with the first‐round results, which indicates the effectiveness of the proposed procedure.
