Abstract:
In this paper, a set of criterion is proposed that assists an engineer in placing a derived requirement as defined by DO-178C in the proper document within the requirement document hierarchy. The proper documentation of derived requirements has historically posed some issues when it comes to requirements-based testing. For one thing, if the derived requirements are inappropriately documented, then it will be very difficult to establish traceability between individual requirements to the elements of design, implementation, and verification. Consequently, the lack of correlation between elements of requirements, design, code, and verification can jeopardize the safety of systems because it will be impossible to establish forward and backward traceability. To this end, the proposed criteria discussed in this work attempts to improve the visibility of derived requirements to prevent the unwanted consequences of masking required information from developers.
