The design, development, and planning of a System-of-Systems (SoS) is a difficult task as it involves several systems, organizations, and complex dynamics between the constituent elements of the SoS. These multitude of factors make SoS difficult to comprehend and model, and SoS solution synthesis becomes a challenging endeavor. Research and development of SoS Engineering (SoSE) processes to account for complexities involved in the design, management, and operations of the SoS has been an active area of research in Systems Engineering and significant progress is made in advancing the state-of-the-art of SoSE in the past decade. In this presentation, we will first review the current practices in SoSE—identifying their common themes and gaps—and then present a three phased SoSE process called the Definition-Abstraction-Implementation (DAI) process. The DAI process draws upon our decade long SoSE experience and critical lessons learned from a variety of government, industry, and academic SoS engagement experiences. The end goal of this work is to provide a domain-agnostic SoSE approach which incorporates both qualitative reasoning and quantitative analytics to create knowledge artifacts needed to support effective analysis for design and evolution of an SoS.
