Dennehy, SMcMullan, RMeyer, Isabella A2025-10-022025-10-022025-08http://hdl.handle.net/10204/14433The Auckland City Rail Link (CRL) project was the first major transport infrastructure project in New Zealand to adopt a requirements-led approach. This paper reflects on lessons learned, with the aim of identifying learnings that may inform approaches in other complex, real-world transport infrastructure projects. The recommendations do not cover the full scope of requirements management or systems engineering, rather they are selected aspects that presented particular challenges or successes, including project planning, tool choice and configuration, establishing the requirements management database as the single, trusted source of truth, change control, stage gates, levels of abstraction, interface management, reliability/availability/maintainability/safety, and post-construction verification. This work is limited to the analysis of a single case, with recommendations made from the perspective of the requirements management team rather than from a wider range of disciplines. Notwithstanding these limitations, the insights and recommendations should be considered for future infrastructure projects, in conjunction with experience and lessons learned from other projects, and with appropriate tailoring for project context – which is always unique.FulltextenAuckland City Rail LinkCity Rail LinkCRLTransport InfrastructureConference PresentationN/A
