“…The techniques they suggest do not consider safety hazards that are not related to the software and for which software design could provide mitigation and/or removal. This does not follow sound safety design principles elaborated in countless references Chudleigh et al (1995); Elliott et al (1994);Fei et al (2001); Gowen (1995); Gowen & Collofello (1994); Halang et al (1998);Jiang et al (1998);Jones et al (2002); Knight (1990); Leffingwell & Norman (1993); Leveson (1995). Leveson states that "...the quality of a safety program is measured by its ability to influence design" Leveson (1995); this ability comes in the form of safeguard requirements that comes from a safety analysis.…”

“…In their research, the authors perform a tailored Failure Mode Effect Analysis (FMEA) technique to study human errors in IIGS. Their research takes an approach similar to that of conventional safety analysis of safety critical systems Chudleigh et al (1995); Fries et al (1996); Gowen (1994) While the technique used by Jiang et al has a lot of merit, their approach also has significant limitations. The aim of their research is to identify surgical errors by focussing on human factors and human errors that can occur in using software.…”
