In this paper we examine some of the challenges associated
with adequately demonstrating the safety of COTS products
as required by goal-based safety standards. The safety
evidence available for COTS products – if any – is sometimes
of questionable quality and applicability. This paper
introduces a framework for assessing the applicability of the
available evidence when selecting a COTS product for
purchase. Use of this framework enables the purchase of a
particular COTS product to be justified from a safety
perspective, as well as identifying where further postpurchase
analysis of the software will be required to support a
safety argument.
