Backwards/forwards traceability Types of traceability Requirements-sources traceability Links the requirement and the people or documents which specified the requirement Requirements-rationale traceability Links the requirement with a description of why that requirement has been specified. Requirements-requirements traceability Links requirements with other requirements which are, in some way, dependent on them. This should be a two-way link (dependants and is-dependent on). Types of traceability Requirements-architecture traceability Links requirements with the sub-systems where these requirements are implemented. This is particularly important where sub-systems are being developed by different sub-contractors Requirements-design traceability Links requirements with specific hardware or software components in the system which are used to implement the requirement Requirements-interface traceability Links requirements with the interfaces of external systems which are used in the provision of the requirements Traceability tables Traceability tables show the relationships between requirements or between requirements and design components .
