ABSTRACTAs systems of systems engineering (SoSE) matures, there is a growing interest in SoSE standardization. This has led the ISO/IEC JTC1/SC7 to establish a study group to investigate future opportunities for SoSE standardization. This paper reviews the approach taken by the study group, the issues that were investigated and the recommendations from the study. The study addresses the current perspectives on SoSE, the state of the practice, the existing level of standardization for SoSE, and the analysis and findings of the potential need for additional SoSE standardization. In looking at the current and potential future state of SoSE standardization, the study examined the adequacy, existing support to, and gaps in current standards that support the needs of SoSE and the SoSE standardization solutions. This article discusses the move toward SoSE standards and the ISO study recommendations for SoSE standards initiatives.
