JPL-D-28444, SOFTWARE FAULT ANALYSIS HANDBOOK - [SOFTWARE FAULT TREE ANALYSIS (SFTA) & SOFTWARE FAILURE MODES, EFFECTS AND CRITICALITY ANALYSIS (SFMECA)] (2 MAY 2005)., The purpose of this document is to describe a standard process for use in performing Software Fault Tree Analysis (SFTA) and Software Failure Modes, Effects and Criticality Analysis (SFMECA) at JPL. The use of this document is not required and is meant only to aid in the creation and implementation of a standard project software analysis process. This document is intended to provide guidance for doing analyses for development of both flight and ground software. These mission and safety critical software analyses are techniques for validation of the software and hardware requirements and design through a systematic evaluation of potential failures and their impacts. The benefit of using these techniques is more reliable performance of the software through improved requirements, less re-design, mitigation for potential problems, and plans for corrective actions prior to failures.
