System of Systems (SoS) is a term often used to describe the coming together of independent systems, collaborating to achieve a new or higher purpose. However, clarity is needed when using this term given that operational areas may be unfamiliar with the terminology. In this paper, we present an approach for refining System and SoS descriptions to aid multistakeholder communication and understanding; building on previous work, we illustrate an example of characterising a likely SoS. By identifying key stakeholders, systems, management and control, this approach supports the initial steps of a SoS security risk assessment approach using a tool-supported framework that supports operational needs towards requirements engineering.
