Which of the following is true about the "5 whys" approach?

The "5 whys" approach is a problem-solving method that focuses on identifying the root cause of a problem by asking "why" multiple times, typically five. The correct statement emphasizes that the process starts with an observed effect or symptom, using it as the foundation for inquiry. By asking why that effect or symptom has occurred, one seeks to uncover the underlying cause.

Beginning with the observed effect sets the context for the investigation, leading to a deeper understanding of how and why the problem exists in the first place. This approach is particularly effective because it encourages critical thinking and helps to prevent issues from being overlooked.

The other options, while related to the technique, do not accurately capture the essence of the "5 whys" as clearly. For instance, stating there are five questions specifically framed as "why" simplifies the process and could mislead one to think it’s rigidly structured when, in reality, the number of inquiries might vary depending on how deep the issue runs. Additionally, while determining all possible causes can be a part of problem-solving processes, the "5 whys" specifically aims to find the root cause rather than every single cause.

In summary, starting with the observed effect and systematically questioning its cause is the crux
