Capturing, verifying and validating requirements is a challenging exercise for large and complex projects because the construction of some stages often overlaps with the design of others. As a result, the final design is sometimes not complete until relatively late in the schedule. Leaving the assurance late means that key staff may have moved onto other projects and the compliance evidence is more difficult to collate. It also makes it much harder to spot and correct any issues without them affecting the overall delivery.
For the London Bridge Station Redevelopment (LBSR) project, verifying that delivery contractors had met all their obligations, that the project had met its obligations to stakeholders and, in the case of Thameslink Programme (TLP), to the Department for Transport (DfT) would have been difficult without a robust requirements management process. This case study looks at scope hierarchy and assurance reporting during the LBSR project. It also shares requirements management best practice, lessons learned and key recommendations for future infrastructure projects.
