Abstract
Systems requirements traceability is an essential discipline in the development of large real-time safety critical systems. The correct capture and utilisation of traceability information is necessary to support verification and certification, and fundamental to change management.
The requirements for systems are at a number of levels of abstraction derived through successive decomposition of the system under development. Accordingly, the associated requirements traceability is equally complex. An additional dimension is the need to encapsulate the rationale for the requirements and its design (an essential element of the safety case) within the traceability structure, and the need to record a range of attributes to support the requirements such as requirement risk and stability.
A traceability model addressing all these dimensions of complexity has been developed. This identifies the requirement to requirement traceability, as well as requirements to design traceability. The structure is then used to organise and define the design rationale and requirement attributes. The traceability model also addresses the need to capture requirements in a range of formats including textual, pictorial and tabular with links to formal specifications where appropriate. An implementation of this model is currently being used to support the development work on a number of aero engine projects.
