Delivery Teams (DTs) or equivalents shall establish and maintain through-life safety cases that provide a compelling, comprehensible, and valid argument that a Product, System, or Service is safe for a given application in a given operating environment. For Platforms and Large Complex Systems, DTs shall utilise the Safety Case Maturity Tool to assess the breadth and appropriate coverage of the produced safety case report and submit findings to QSEP for inclusion in the Safety Case Maturity Dashboard.
