FTA (Fault Tree Analysis) is prepared by identifying top-level event, intermediate events, basic events, and failure probabilities.

• Identify the top-level event that needs to be analyzed

• Break down the top-level event into intermediate events

• Identify the basic events that contribute to each intermediate event

• Assign failure probabilities to each basic event

• Construct the fault tree diagram based on the above information
