What is a Pareto Chart? Guide to Creating a Pareto Chart and Pareto Analysis

A pareto chart is an incredibly useful tool for data analysis and quality improvement. This in-depth guide will teach you everything you need to know about pareto charts - what they are, how to make one, and how to use a pareto chart for pareto analysis. Read on to learn how to harness the power of the pareto principle to prioritize issues and identify solutions.

Introduction to the Pareto Chart and Principle

A pareto chart contains both bars and a line graph, arranged in descending order of frequency. The bars represent individual values, with the highest frequencies on the left. The line graph represents the cumulative total percentage. This chart draws on the pareto principle, which vilfredo pareto first observed in 1906.

The Italian economist noticed that roughly 80% of the land in Italy was owned by only 20% of the population. He later discovered that this 80-20 distribution applied to other areas as well. Over time, this became known as the pareto principle or 80-20 rule - 20% of causes lead to 80% of problems.

This principle highlights the uneven distribution of effects. A relative few causes, inputs, or efforts usually lead to the majority of results, outputs, or rewards. Pareto charts help identify the "vital few" sources of problems from the "trivial many." Focusing resources on the vital few inputs can lead to significant gains ("the greatest good for the greatest number").

How to Create a Pareto Chart Step-By-Step

Creating a pareto chart is straightforward once your data is organized. Here is a step-by-step guide:

  1. Choose the parameters to chart. What types of defects, issues, or categories do you want to compare? For example, you may chart types of customer complaints, production errors, or late arrivals.

  2. Gather the data and count the number of occurrences. Tally the frequency of each type. Organize your data in a table or spreadsheet with categories in one column and frequencies in another.

  3. Sort the data in descending order. Place the categories with the highest frequencies first. The first bar will be the tallest.

  4. Create a bar chart with the categories. Place categories on the horizontal axis and frequencies on the vertical axis. The bars will descend from left to right.

  5. Add a cumulative line graph. Convert the frequencies to percentages. Plot the cumulative percentages and add a line graph.

  6. Add titles and labels. Make sure to label the horizontal and vertical axes. Give the chart a descriptive main title.

That's the basic process. For details and examples, read on!

Pareto Charts versus Other Charts

Why use a pareto chart instead of a pie chart or bar graph? Regular bar graphs only show individual values. Pie charts illustrate percentages but not trends over time.

Pareto charts have distinct advantages:

  • They highlight the most significant factors. The tallest bars immediately draw the eye.

  • The descending bars visually prioritize issues.

  • The cumulative line shows the cumulative impact on the total.

  • They help identify the “vital few” to focus on.

Pareto charts are highly recommended for:

  • Quality control and root cause analysis

  • Analyzing customer complaints and common defects

  • Identifying areas for process improvements

  • Prioritizing issues and focusing resources

  • Communicating data visually and convincingly

Pareto Chart Example

Let's walk through a simple example. Imagine a restaurant in Anytown wanted to reduce customer complaints. They collected data about the types of complaints received over the past year:

Type of ComplaintFrequencyCold food105Long wait97Rude service73Noise level37Dirty facilities22

First, they sorted the types of complaints in descending order of frequency. Cold food complaints were most common, followed by long waits. Rude service, noise, and dirty facilities complaints were less frequent.

They created a bar chart with complaint types along the x-axis and frequencies along the y-axis. Cold food had the tallest bar at 105 complaints. The bars descended in height.

Next, they calculated the percentage and cumulative percentage for each complaint type:

Type of ComplaintFrequencyPercentageCumulative PercentageCold food10534%34%Long wait9732%66%Rude service7324%90%Noise level3712%102%Dirty facilities227%109%

They plotted the cumulative percentages as a line graph. It started at 34% and ended at 109%.

The final pareto chart vividly illuminated the key complaint drivers. It was clear that focusing on solving cold food and long wait issues could reduce complaints by 66%. The restaurant now had quantitative data to prioritize vital improvements.

Tips for Creating Pareto Charts

Follow these tips when making your own pareto chart:

  • Include a sufficient number of issues - The more categories, the better the perspective. Aim for 6-12 issues along the x-axis.

  • Label axes and bars clearly - Describe the units of measure. Write categories in full instead of abbreviating.

  • Show cumulative percentage on the secondary axis - Convert the frequencies to percentages for the cumulative line graph.

  • Make the bars & line clearly distinguishable - Use contrasting colors. Make the bars wider than the line.

  • Highlight the tall left bars - Draw attention to the vital few categories. Consider darker colors or increasing bar width.

  • Add context with a title - Summarize the purpose at the top. Include the date range and other specifics.

Pareto Analysis Applications

Pareto analysis refers to using the pareto principle to identify key issues to prioritize. Pareto charts provide an excellent graphical tool for conducting pareto analysis across many domains, including:

  • Manufacturing & Production - Charting defects and errors to improve quality.

  • Business & Sales - Determining which products drive the majority of revenue.

  • Healthcare - Reducing patient readmission rates.

  • Software - Analyzing features that drive engagement and conversions.

  • Marketing - Identifying how customers find your website or which campaigns convert best.

  • Academics - Helping students prioritize key concepts to study.

The examples are endless. Wherever some factors exert more influence than others, pareto analysis can help identify the “vital few” inputs with the greatest impact on outputs. Concentrating efforts on those vital few factors can lead to outsized gains.

Using Pareto Charts for Quality Improvement

Pareto charts have a long history in quality control and process enhancements. Some examples include:

  • Product defects - Chart different failure modes. Target top failure modes for root cause analysis.

  • Customer complaints - Identify frequent complaints to address. Increase customer satisfaction.

  • Supply chain issues - Find causes of delays or shortages. Improve supplier relationships.

  • Medical errors - Reduce mistakes and preventable complications. Improve patient safety.

  • Process inefficiencies - Cut waste and streamline processes. Lower costs.

Analyzing with pareto charts helps zero in on the most impactful issues deserving focus. Teams can use the 80-20 rule to prioritize quality improvement initiatives for the vital few sources of problems. Results compound over time through iteratively working on significant items.

Tips for Conducting Pareto Analysis

Keep these guidelines in mind when performing pareto analysis:

  • Define the issue first - What outcome do you want to improve? Get specific.

  • Determine key categories - What inputs or groups are you comparing? Pick around 6-12.

  • Gather sufficient data - Larger data sets give a more accurate picture.

  • Create the pareto chart - Use the steps outlined earlier.

  • Identify the vital few categories - Highlight the tall bars on the left.

  • Focus on the vital few - Prioritize addressing the top issues uncovered.

  • Track progress over time - Revisit with additional pareto analyses. Continually improve.

The pareto chart condenses complex data into an intuitive graphic to support data-driven decisions. Keep iterating to make ongoing improvements.

Creating Pareto Charts in Excel

Excel offers an easy way to make pareto charts. Just follow these steps:

  1. Enter the category labels in one column and frequencies in another.

  2. Highlight the data and click the Charts tab. Select the 2-D Pareto chart option.

  3. Excel will automatically create a pareto chart with bars in descending order.

  4. To add the cumulative percentage line, right-click the bars, select "Add Chart Element - Lines", and choose cumulative percentage.

And that's it! Customize the chart as needed by adding titles, axis labels, legends, and data labels. Excel makes pareto chart creation a breeze.

Limitations of the Pareto Principle

The pareto principle is an extremely useful concept, but it does have some limitations:

  • It's not an ironclad law - There are exceptions where results are more evenly distributed.

  • Data availability can obscure key factors - Lack of visibility across all inputs.

  • It should not replace detailed analysis - Need to verify causes and not just assume 80-20.

  • It works best for objective quantitative data - Less applicable for subjective preferences.

  • It doesn't account for synergies - Multiple smaller factors together may have a large impact.

The pareto principle is a helpful guide, but shouldn't substitute for critical thinking. Always dig deeper into the root causes driving outcomes.

Conclusion and Key Takeaways

To recap, here are the key takeaways:

  • Pareto charts combine a bar graph sorted in descending order with a cumulative percentage line. This highlights the vital few inputs with the biggest impact.

  • The pareto principle states that 80% of outcomes come from 20% of causes. Use pareto analysis to identify and prioritize addressing those vital few factors.

  • Pareto charts help visualize data, identify key issues, communicate findings, and prioritize quality improvements efforts for outsized gains.

  • Creating pareto charts is easy with spreadsheet software. Enter data, sort by frequency, create bars, and add a cumulative line.

  • Focusing resources and efforts on the key drivers identified through pareto analysis allows for effective quality control and process enhancements.

Pareto charts and the 80/20 rule provide extremely useful heuristics for data analysis, research, problem-solving, and continuous improvement initiatives across many disciplines. Now that you know how to create and apply pareto analysis, you can leverage the vital few factors in your own work or business!
