What is the main focus of Pareto analysis?

The primary focus of Pareto analysis is to identify and eliminate the most significant defects. This technique is based on the principle that a small number of causes often lead to a large percentage of problems, commonly referred to as the 80/20 rule. In practice, this means that by targeting the most critical issues—often just a few key defects or causes—organizations can effectively improve their processes and outcomes. Pareto analysis helps prioritize efforts by highlighting the areas that will yield the greatest impact when addressed, allowing for more efficient allocation of resources to improve quality and reduce defects significantly. This approach is highly effective in quality management and process improvement initiatives.
