How to fill out pareto charts

How to fill out Pareto charts:

1. Identify the problem or issue: Start by identifying the problem or issue that you want to analyze using a Pareto chart. This could be anything from customer complaints to production errors.
2. Collect data: Gather data related to the problem or issue. This could involve mining through customer feedback, reviewing quality control reports, or analyzing production data.
3. Categorize the data: Categorize the collected data into different categories or groups. For example, if you are analyzing customer complaints, you could categorize them into different types of complaints such as delivery delays, product quality issues, or customer service problems.
4. Calculate the frequency or count: Determine the frequency or count of each category. This refers to how many times each category appears in the collected data. It is important to have accurate and reliable data to ensure the validity of your Pareto chart.
5. Calculate the cumulative frequency: Determine the cumulative frequency for each category. This is the running total of the frequencies as you go through the categories from highest to lowest. It helps in visualizing the cumulative impact of each category on the overall problem.
6. Calculate the percentage: Calculate the percentage contribution of each category by dividing the frequency of each category by the total frequency. Multiply the result by 100 to get the percentage value.
7. Plot the data: Plot the categories on the horizontal axis and the percentage on the vertical axis. Start with the category that has the highest frequency and continue in descending order.
8. Draw a cumulative percentage line: Draw a line graph representing the cumulative percentage. This line should start at zero and reach 100% at the end. It helps in identifying the vital few categories that account for a significant portion of the problem.
9. Analyze the chart: Interpret the Pareto chart to gain insights into the problem or issue. Identify the categories that make up the majority of the problem and prioritize them for further investigation or improvement efforts.
