This paper discusses the DO-254 principle of requirements traceability and describes how a new tool, ReqTracer, can assist with the challenge of establishment of a requirements-driven design flow by simplifying the process and lowering project costs. DO-254 is a new challenge facing aerospace companies and, in some cases, companies serving other safety- and mission-critical markets. A key element of DO-254 programs is the establishment of a requirements-driven design flow.
