RAD-XP: Tabletop Exercises for Eliciting Resilience Requirements for Sociotechnical Systems

Despite noble intentions, new technologies may have adverse effects on the resilience of the sociotechnical systems into which they are integrated. Our objective was to develop a lightweight method to elicit requirements that, if implemented, would support sociotechnical system resilience. We developed and piloted the Resilience-Aware Development Exercise Protocol (RAD-XP), a method to generate tabletop exercises (TTXs) to elicit resilience requirements. In the pilot study, this approach generated 15 requirements from a one-hour TTX, where the majority of requirements were found to support resilience. Participants indicated via survey that RAD-XP was effective and efficient, and that they would want to use RAD-XP regularly throughout the agile development process. We discuss future research and development to refine this approach to eliciting resilience requirements.
