Pareto Analysis

Overview

Pareto Analysis is a problem-solving technique that helps businesses identify the most significant issues that need to be addressed.

It is based on the Pareto Principle, which states that roughly 80% of effects come from 20% of causes.

By focusing on the 20% of causes that are responsible for the majority of the problems, businesses can make the most efficient use of their resources to solve the most critical issues.

Two well-known global brands that have used this strategy are Amazon and Toyota.

Amazon used Pareto Analysis to identify the most significant issues that were causing delays in their delivery process.

They found that 20% of their suppliers were responsible for 80% of the delays.

By focusing on these suppliers, they were able to improve their delivery times significantly.

Toyota, on the other hand, used Pareto Analysis to identify the most common defects in their vehicles.

They found that 20% of the defects were responsible for 80% of the problems.

By focusing on these defects, they were able to improve their overall quality and customer satisfaction.

How to

The following steps outline how to conduct a Pareto Analysis:

1. Define the problem: Clearly define the problem that needs to be solved.
2. Collect data: Collect data on the problem to identify the causes.
3. Identify the causes: Identify the causes of the problem and list them in order of frequency.
4. Create a Pareto chart: Create a Pareto chart to visually represent the data and identify the 20% of causes responsible for 80% of the problem.
5. Analyze the chart: Analyze the chart and focus on the causes responsible for the majority of the problem.
6. Develop a solution: Develop a solution to address the causes responsible for the majority of the problem.
7. Implement the solution: Implement the solution and monitor the results.

Best Practices

• Clearly define the problem that needs to be solved.
• Collect data from reliable sources.
• Use a team approach to identify causes and develop solutions.
• Focus on the causes responsible for the majority of the problem.
• Develop and implement a solution that addresses the root causes of the problem.
• Monitor the results and make adjustments as necessary.

Examples

Here are two potential examples of how small businesses can use Pareto Analysis to solve problems:

1. A restaurant is experiencing long wait times for customers during peak hours. They conduct a Pareto Analysis and find that 20% of their menu items are responsible for 80% of the orders. By simplifying their menu and focusing on the popular items, they can reduce wait times and improve customer satisfaction.
2. A small retail store is experiencing high levels of theft. They conduct a Pareto Analysis and find that 20% of their products are responsible for 80% of the theft. By increasing security measures for these products, they can reduce theft and improve profitability.
