The value of the 5 whys, IMO, isn't to find absolute truth, it's to avoid making stupid and easily avoidable mistakes by forcing people to talk to one another while developing solutions. In many places, people have multiple concurrent demands on their time, and that can force people into a reactionary get-it-done-quick mindset. The 5 whys are a way to minimize the impact of time pressure by having a thorough problem-solving rubric that is expected to be followed. Basically, it's cover for people to devote more time to communication and critical thought.
