Abstract This paper describes a SysML‐based approach for the definition of the different layers of requirements necessary for a full functional specification of complex systems and/or systems‐of‐systems. The approach is specifically suited to those cases in which the development of the system as a whole and that of the single system elements (or of subsets of system elements), are under the responsibility of different development teams, within the same firm or belonging to different firms. The process is based on a recursive approach, in which each layer of the development must: i) interact with its “customer”, through the acquisition and analysis of the stakeholder requirements applied to the system, ii) define the system‐level requirements as a result of a black‐box analysis of the system's behavior, and iii) perform a white‐box analysis for the definition of the system elements' requirements.
