Software failure analysis in requirement phase
Sudhanshu Gupta, Gogate Vaibhav Vinayak, Atul Kumar Gupta · 2012
Software integrity is of prime concern in today's computerized world. Software failure makes the development of fault tolerant software system, a matter of concern. Failure Modes and Effects Analysis (FMEA) and Fault Tree Analysis (FTA) are traditional techniques that have been used to improve the reliability of mechanical systems. In this paper we propose a formalized approach to find vulnerable failure modes of software systems by synthesizing use case specifications with integrated technique of Software FMEA and Software FTA. We demonstrate the applicability of the approach further, using a case study.
