Abstract: In this paper, empirical research aiming to improve agility in SoS architecting by a model-based, knowledge-driven and collaborative approach is reported. The approach is based on eliciting existing knowledge, visualising it by immediate modelling, verifying consistency of the knowledge by continuous review, and identifying and planning for missing knowledge. Agility is mainly achieved via: 1) performing these activities concurrently in modelling workshops, where operational, functional and physical aspects of the solution are developed simultaneously; 2) with the collaboration of cross domain/organisation knowledge sources. Continuous customer training is another tool adopted for enhancing collaboration effectiveness with the customer. Formulated steps were implemented and assessed in a case study. From the practitioner's point of view, lessons learned in the scope of this study can help companies to speed-up the shift from traditional systems engineering to architecture-driven, knowledge-focused and model-based SoS engineering practices.
