A cause-and-effect diagram, often referred to as a fishbone diagram or Ishikawa diagram, is specifically designed to identify and analyze the various factors that contribute to a particular problem or outcome. This visual tool helps teams systematically brainstorm and categorize potential causes, making it easier to pinpoint root causes of issues and understand the relationships between different factors.

The structure of the diagram allows users to lay out a central problem and branch out with potential causes in a logical manner. This clarity facilitates deeper discussions on how these factors interrelate and impact the overall situation, which can lead to more effective solutions. By mapping out these influences, organizations can focus their efforts on addressing the most significant contributors to problems.

In contrast, the other options do not reflect the primary purpose of a cause-and-effect diagram. For instance, a list of employees' performance metrics is typically organized in a different format focused on individual assessments, while a historical timeline illustrates events over a time period rather than causal relationships. Comparing different data sets involves analysis of numerical data or trends, which is also not aligned with the identifying cause-and-effect functionality of the diagram.
