Pareto Analysis identifies the “vital few” issues that cause the majority of problems, usually presented as the 80/20 rule. While it is useful for prioritisation, its limitation is that it only highlights the frequency of issues and not the root causes behind them. In James’s example, identifying that “website errors” are the top cause of complaints is useful, but it doesn’t explain why the errors occur. Therefore, further investigation such as root cause analysis or process mapping is required to implement corrective action. Another limitation is that Pareto analysis is based on quantitative data only, not qualitative, meaning it cannot capture customer perceptions or subjective insights. This reinforces the need to use Pareto in conjunction with other diagnostic tools for effective problem solving. In practice, category managers must use Pareto as a screening tool to highlight priorities and then follow with more detailed analysis to ensure improvements are sustainable.
