Abstract
Software fault tree analysis SFTA and software failure modes and effects analysis SFMEA are two well known recommended approaches for the analysis of software induced hazards in the system and are adapted in the software domain by employing the concepts of standard hardware safety approaches namely fault tree analysis FTA and failure modes and effects analysis FMEA respectively. Both SFTA and SFMEA approaches, since their inception in the software domain, have been explored, either individually or jointly, by researchers at different stages of software development. This paper presents the critical review of the published work about the applications of both these approaches in three phases, namely requirements analysis, design and implementation/coding phases of software life cycle. After presenting the analytical review, the paper identifies the problems that are currently faced during the applications of these approaches and guides the directions for carrying out further research.
