The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question “Why?”. Each answer forms the basis of the next question.
What are the three basic rules of cause and effect?
There are three criteria that must be met to establish a cause-effect relationship: The cause must occur before the effect. Whenever the cause occurs, the effect must also occur. There must not be another factor that can explain the relationship between the cause and effect.
