On complex rail projects involving a step change in technology or capability, it is important to understand what functionality is required from the system, especially if such changes are new or novel. This paper details a case study (Deep Tube Upgrade Programme) where a structured functional breakdown approach was developed to provide stakeholders (including non‐Systems Engineering practitioners such as operators and maintainers) with an accessible means of checking their life‐cycle concepts and stakeholder requirements for completeness. The approach also enabled the decomposition of those needs into system design requirements for allocation to one or more of the 20 delivery projects, to ensure they will deliver the required emergent properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
