A Pareto Chart is a specialized type of bar graph that visually represents the frequency or importance of problems or causes in a process, highlighting the most significant factors. The concept is rooted in the Pareto Principle, often referred to as the 80/20 rule, which suggests that a small number of causes (around 20%) are responsible for a large portion (around 80%) of the problems or effects.

Using a Pareto Chart allows organizations to prioritize their problem-solving efforts effectively. By identifying the most frequent issues or significant sources of defects, teams can concentrate their resources on addressing the root causes that will yield the highest impact. This data-driven approach is particularly valuable in process improvement initiatives, quality control, and operational efficiency.

Other options do not define the primary purpose of a Pareto Chart. While identifying job performance metrics, documenting lean methodologies, or guiding employee feedback sessions may be relevant activities within a management context, they do not encapsulate the specific function of a Pareto Chart. This tool is distinctly focused on analyzing and visualizing problem frequencies, thus guiding decision-making based on empirical data.
