Increasing efficiency in business operations is the prime objective of any organization. In the pursuit of this objective, data analysis tools play a pivotal role. Among the myriad data analysis tools available, one particularly influential visualization tool is the Pareto Chart. This article decodes everything you need to know about how to create a Pareto Chart and its importance in business data analysis.
Understanding the Concept of a Pareto Chart
A Pareto chart is a type of chart that possesses both bars and a line graph, where individual values are represented in descending order by bars, with the cumulative total represented by the line. It provides two types of data: the number of incidences (which is a bar graph) and the cumulative percentage of these incidences (which is a line graph). This dual aspect hierarchical ordering enables analysis of both the frequency and impact.
Succinctly, a Pareto Chart focuses on the significant elements and helps to identify the ‘vital few’ from the ‘trivial many’. As per Pareto’s principle, 80% of the problems arise from 20% of the causes.
The ordering of the categories from highest to lowest enables easy identification of the most significant factors. This is why Pareto Charts are also known as sorted bar charts.
Importance of Pareto Charts in Business Data Analysis
Pareto Charts are a potent tool for businesses to make impactful decisions. They help in recognizing patterns, prioritizing problem-solving, and making decisions based on data to improve processes and systems incrementally. This in turn aids in cost reduction and improving customer satisfaction, as well as profitability.
For example, a factory might use a Pareto Chart to understand the most common reasons for late deliveries or product defects. Then they focus their efforts first on reducing the most significant causes.
The Pareto Chart enables leaders within the business to easily visualize where the most significant problems or opportunities lie. This allows strategies to be developed to target the areas where the most impact can be made.
Detailed Steps To Creating a Pareto Chart for Analysis

Creating a Pareto Chart involves a few well-defined steps. It starts with identifying the problems or causes that you want to understand better to improve the process.
Next, deciding on the appropriate measurement is important. It can be count (the number of times a problem occurs), cost (the weight of consequence that each problem carries), or any other appropriate measure.
Then, categorize and chronicle the data collected. Listing the problems and their frequency or cost, and determining the total problems, you start drawing the Pareto Chart.
Handy Tips to Effectively Use Pareto Charts for Data Analysis
To use a Pareto Chart effectively, you should ensure that your data is comprehensive and represents the entire process or system you want to improve. Also, while drawing the cumulative percentage line, it has to coincide with the Pareto line at the end.
Overuse of Pareto charts can lead to over-simplification of complex problems. Hence, while a Pareto counts frequencies, its use should be balanced with other tools that provide deeper analysis.
Last but not least, after the action has been taken, continue to collect data to verify whether the targeted problem has decreased. This proves the efficiency of Pareto Charts.
Overall, understanding and using Pareto Charts effectively can pave the way for significant improvements in business processes. The exercises of plotting a Pareto Chart are as critical as the resulting insight that aids in decision-making.
