Below are steps to create a pareto chart in excel –

1. Collect the Raw Data including the Category (cause of a problem) and their Count

   
   

2. Calculate the percentage of each category and further compute the cumulative percent

   The percent will be calculated using the formula =(C3/$C$13) *100, applying throughout the other cells.

   

   Cumulative Percentage

   It is the method of calculating the frequency distribution and will be calculated successively by adding the percent with other frequencies. So, the formula will be =D6+C7. After sorting the values from largest to smallest, we calculate the cumulative percentage for each of the categories.

   

3. Select category, count, and cumulative percent Range together as shown below

   

   Go to the Insert tab in Excel and select a 2-D column bar graph.

   

   Now the Pareto chart created is shown below:

   

4. Select the cumulative percent bars and change the series chart type to Line.

   The red bars are the cumulative percentage bars, select any one of the bars and change the series, select Line from the change chart type.

   

   Now the Pareto chart will look like shown below:

5. Right-click on the cumulative total line (in red) and choose format data series.

   

   and select the secondary axis in excel

   

   Select Secondary axis and close the Format Data Series window.

   Now the Pareto chart will look like as shown below

   

6. Click on the right-hand axis and select format axis,

   

   then under the axis option tab, select maximum to set it to be fixed, and set the value to 100

   

   In Axis Options, select the Maximum from Auto to fixed and enter a value 100 manually and close the format axis window

   Finally, the Pareto chart will look like

   

   

The chart above shows that 80% of the effects come from 20% of the causes.

Advantages

• The Pareto chart highlights the major cause of the problem that hampers a process
• It helps to rectify the major problems and thus increases organizational efficiency. Once the big hitters in a process are discovered using this technique, one can move ahead for the resolutions, thus increasing the efficiency of the organization
• It also enhances problem-solving skills as it enables you to sort out business-related issues into strong facts. Once you've vividly laid out these facts, you can start the planning important to take care of the issues.
• It improves decision making in a process.
• It helps the organizational team to focus on the input that will have a greater impact in accordance with the 80/20 rule.

Limitations

• The Pareto chart doesn't provide any insight into the root cause of the problem.
• A single cause or a reason category may further have other factors involved, so to find the major impact at each level of the problem, we have to create many Pareto charts. So, lower levels of the Pareto chart are often required.
• Pareto chart is based on the frequency distribution Frequency distribution refers to the repetitiveness of a variable, i.e., the number of times a variable occurs in a data set. In excel, it is a function to tabulate or graphically represent the recurrence of a particular value in a group or at an interval. read more ; hence it cannot be used to calculate the mean, standard deviation, and other statistical values may often require.
• Pareto chart can't be utilized to compute how awful the issue is or how far changes would bring a procedure back into specification.

Things to Remember

• Before creating a Pareto chart, it is necessary to categorize the issues, and it is considered to be a good practice to keep the categories less than 10 in numbers.
• It is based on the past data, so for continuous improvement of a process, it is necessary to revamp the data on a periodic basis because the Pareto analysis is based on the historical data and doesn't provide the forecast analysis.
• Always create the secondary y-axis with percentage descending in increments from 10 to 100.
• It helps in providing an easier way to make a distinction before and after Pareto analysis Pareto analysis is a decision making technique based on the 80/20 rule where the company can achieve 80% of the project's benefits by doing the 20% of the work, or the 80% problems of the company are traced to 20 % causes. read more to verify the process changes had the desired outcome.
• We can create multilevel Pareto charts for each issue and can further perform another Pareto analysis on the sub-level issues and so on.
