The primary purpose of a Pareto chart is to prioritize problems based on frequency. This tool is rooted in the Pareto principle, also known as the 80/20 rule, which suggests that a small number of causes often lead to the majority of problems. By using a Pareto chart, practitioners can visually represent data to identify the most significant issues or defects that need attention.

For instance, if a company is experiencing several types of defects in its processes, a Pareto chart allows the team to see which defects occur most frequently. This means that by addressing the top contributors to the issues, organizations can have a more substantial impact on improving quality and reducing inefficiencies.

This prioritization helps teams focus their resources and efforts where they can achieve the most significant results, ultimately leading to more efficient problem-solving and better process management. Thus, the use of a Pareto chart is essential in distinguishing key issues that need to be tackled first, making it a critical component of Six Sigma methodologies.
