C. Fault tree analysis Fault tree analysis (FTA) is a systematic, deductive method used to identify the potential causes of system failures. It involves constructing a tree-like diagram (fault tree) to represent the various logical relationships between system failures, sub-system failures, and component failures. By doing so, it helps in diagnosing risk factors and predicting potential points of failure within a system. Here’s a brief overview of why the other options are less suitable for this specific purpose:

C. Fault tree analysis The main purpose of the Fault Tree Analysis is to help identify potential causes of system failures before the failures occur. It can also be used to evaluate the probability of the top event using analytical or statistical methods. These calculations involve system quantitative reliability and maintainability information, such as failure probability, failure rate, and repair rate.https://online.visual-paradigm.com/knowledge/root-cause-analysis/how-to-find-root-cause-using-fault-tree-diagram/

Fault tree analysis is a method that involves the use of predictive or diagnostic analytical tools to expose risk factors.

C. Fault tree analysis Fault tree analysis is a method that involves the use of predictive or diagnostic analytical tools to expose risk factors. It is a technique used in risk management to analyze the potential failure modes of a system, process, or project. It works by visually representing the logical relationships between various events and conditions that can lead to a specific undesirable outcome (often referred to as a "top event" or failure). By analyzing these relationships, fault tree analysis helps identify the root causes and risk factors contributing to the potential failure. While the other options (A. Scenario analysis, B. Sensitivity analysis, D. Cause and effect analysis) are also important methods in risk analysis and management, they may not necessarily rely on predictive or diagnostic analytical tools as directly as fault tree analysis does.
