In this paper we propose an information structure enrichment of relational models underlying design structure models typically used in System-ofSystems. Such design structures are algebraically, logically and topologically mostly unstructured relations as treated within naïve set theory. The paper also aims to show how an enriched information structure can be applied to monitor the health status of a System-of-System as an alternative to fault trees.

Computational algorithms can be described in many methods and implemented in many languages. Here we present an approach using storytelling methods of computer game design in modeling some finite-state machine algorithms and applications requiring user interaction. An open source software Twine is used for the task. Interactive nonlinear stories created with Twine are applications that can be executed in a web browser. Storytelling approach provides an easy-to-understand view on computational algorithms allowing communication with people with no computer science education. It also allows rapid prototyping and testing in mixed background work teams.
