Software Fault Tree Analysis Training, Software FTA Training
Software Fault Tree Analysis Training, Software FTA Training is a 2-day workshop. It is a systematic, deductive (top-down), graphical methodology for defining a single, specific, and undesirable event, and determining all possible reasons (failures) that could cause that event to occur. Failures can result from software causes.
The three components of Software FTA are the fault tree diagram, the events and logic gates. Fault Tree Analysis is s a systematic method of system analysis and part of operations research in system reliability and safety. Fault Tree Analysis (FTA) examines the software from top-down and provides graphical symbols for ease of understanding. It incorporates mathematical tools to focus on critical areas. Participants in this course learn the concepts of Fault tree analysis as it is used a symbolic “analytical logic techniques” and its application in reliability and safety analysis.
Learn how basic events, often made up of failures at the component level, could lead to a hypothesized failure of a software system. Learn how fault tree analysis (FTA) is used in software development and software engineering, analysis practices such as reliability, maintainability and safety.
