Which area in a Cause and Effect diagram represents the "effect"?

In a Cause and Effect diagram, also known as a fishbone diagram or Ishikawa diagram, the "effect" typically represents the main problem or outcome that you are trying to analyze. This is usually placed at the end of the "bones" of the fish, indicating the final result of various contributing factors or causes.

Choosing B as the correct area aligns with this layout, as it signifies where the outcome under investigation is located. The effect is what prompts the need to investigate further and understand what factors contribute to it. The various causes, which are often categorized into different groups, are shown along the "bones" of the diagram and point towards the effect, illustrating the relationship between cause and effect in the overall process.

The effectiveness of this diagram arises from its ability to visually display the relationship between different causes and their resulting effect, which is vital for identifying root causes during problem-solving. Thus, identifying the correct representation of the "effect" within the diagram is critical to understanding the overall flow of analysis and implementing appropriate solutions.
