A Systematic and Traceable MOSA Evaluation Process for Systems Architectures: A Digital Engineering Tool

Abstract A process for evaluating the degree to which an architecture embraces Modular Open Systems Approaches (MOSA) is germane ensuring that MOSA principles are actually used in development of defense systems architectures. Furthermore, such a provides artifacts can be by program offices justify their key architectural decisions and prove they embrace as required. Therefore, approach facilitates assessment requirements compliance—rather than system designs or products—provides added benefit applicable quality attributes incorporated into architectures during phase. To this end, systematic traceable evaluation uses derived sets evaluable criteria evaluate developed. The utilizes digital engineering establish, within authoritative source truth (model), traceability relationships queried, analyzed, validate whether resultant will exhibit modularity openness characteristics.
