Question 6

1. FTA or _______________, sometimes called cause and effect tree analysis, is a method to describe combinations of conditions or events that can lead to a failure.
2. A cause and effect tree is composed of conditions or events connected by “AND” gates and “OR” gates.

An effect with an “____” gate occurs only if ALL of the causes below it occur; an effect with an “__” gate occurs WHENEVER any of the causes occur.

Answer 6

Fault Tree Analysis
And, Or

Question 7

_________ is defined as “that condition (or interrelated set of conditions) having allowed or caused a defect to occur, which once corrected properly, permanently prevents recurrence of the defect in the same, or subsequent, product or service generated by the process.”
