Bombardier Transportation Australia has supplied 22 A-City Class 4000 electric passenger trains to the SA Department of Planning, Transport and Infrastructure (DPTI). DPTI specified over 1,000 system requirements and a range of standards against which the solution has to be demonstrably verified.
Nova Systems was engaged by BTA to establish an integrated Requirements Management function, including tailoring of processes and establishing a baseline of the system requirements. Using best-practice in Requirements Management, Nova Systems devise a risk-oriented approach that fully integrated the system requirements with verification including design review, quality inspections, formal testing of rolling stock, certification and acceptance activities.
Nova Systems performed a requirement compliance assessment to determine risk areas for the project. High risk areas were worked through by BTA with the client, and a staged approach was created to enable progressive verification of system requirements, and reducing the risk of compliance before the completion of design. Nova Systems also prepared the Verification Plan, which took the requirements of the Acceptance standard and mapped out verification schedule-of-activities to match.
This planning gave BTA and DPTI the shared roadmap to progressively complete acceptance by identifying what was required from each and at which sub-stage of the project. The key to success for this project was the use of a proper Requirement Management tool to analyse and track requirements, performs validation against customer needs, examines the risk of compliance at an early stage, and allows for two-way communication to reduce compliance risk to an acceptable level.
