Back to school can be a stressful time, but the Pareto law, also known as the 20/80 rule, offers an approach to effectively manage this period. This method proposes a simple principle: focus your efforts on the 20% of actions that generate 80% of the results. Whether it's for project management, product sales or logistics optimization, applying this rule can help you avoid getting overwhelmed. Find out how to apply it in your daily life.
Understanding Pareto's Law
Pareto's law, developed by Italian economist Vilfredo Pareto , is an economic theory that also serves as a management technique . It is based on the idea that 80% of effects are generally the result of 20% of the causes. In other words, a majority of results can be attributed to a minority of actions .
This law is commonly used in business to identify the most profitable elements, and thus prioritize actions . It can help leaders and managers optimize their time management, by focusing on high-impact tasks.
In summary, the Pareto law is an analysis tool that helps identify and focus on the most significant factors, with an emphasis on added value .
The principle behind the 20/80 method
The 20/80 method is based on the observation that 20% of actions generate 80% of results . However, it is essential to note that this distribution is not always precise and can vary. The basis of this principle is to focus on finding and identifying the 20% of actions or causes that will have the greatest impact.
It is used to determine the most important tasks, those that bring the most results, and prioritize their completion. For example, in a company, it may involve focusing on the small number of customers that generate the majority of revenue. This method helps to optimize the use of resources, increase efficiency and improve decision-making.
In short, the 20/80 principle is a strategic thinking tool to identify the key elements that lead to success and focus efforts on them.

How to optimize your product management with the Pareto law
Optimizing your product management using the Pareto law begins with identifying the 20% of your SKUs that generate 80% of your sales or profits. This analysis can be crucial to the profitability of your business.
First , it is necessary to identify those products with high profitability, whether in terms of sales volume or margins. You can use dashboards or analysis tools to collect this data.
Second , once you have identified these products, focus your efforts on ensuring their availability. This may involve specific strategies for managing [stock items], ordering replenishment, or even highlighting these products in your store.
Third , it’s also essential to pay close attention to these products in your [marketing] efforts. This could mean prioritizing these products in your advertising campaigns or in your [e-commerce] strategy.
Finally, it is important to note that the Pareto distribution is an approach and not an [exact science]. The proportions can vary and must be re-evaluated regularly to adapt to changes in consumer and market behavior.
How to make a Pareto chart?
Steps to build a Pareto chart
The construction of a Pareto table generally follows a precise process:
-
Problem Identification : Start by listing all the problems encountered in the context you are trying to analyze. Also note the number of occurrences of each problem.
-
Data Organization : Sort issues in descending order, from most frequent to least frequent.
-
Calculating Percentages : For each problem, calculate the percentage it represents of the total number of occurrences.
-
Calculating the cumulative percentage : Add the percentages starting with the largest to obtain the cumulative percentage.
-
Creating the table : Record the information in a table. On the y-axis, plot the cumulative percentage. On the x-axis, list the problems in order of frequency.
-
Graphing : Plot a curve on the graph to visualize the distribution of problems.
By following these steps, you can create an effective Pareto chart to visualize and understand the key issues that need to be addressed.
Example of Pareto Chart in Action
To illustrate the effectiveness of the Pareto chart, let's take a concrete example from the field of project management. Suppose a project manager notices that certain recurring problems are hindering the progress of the project.
Here's how he might use the Pareto chart:
- Problem Identification : Delivery delays, poor communication, lack of resources and unsatisfactory quality are identified as the main problems.
- Data organization : These issues are sorted by frequency of occurrence. Delivery delays come first, followed by poor communication, lack of resources, and finally unsatisfactory quality.
- Calculating Percentages : The percentages for each problem are calculated relative to the total number of problems.
- Creating the table : This data is then entered into the Pareto table, with the problems on the x-axis and the cumulative percentage on the y-axis.
- Graphical representation : Finally, a curve is plotted on the graph to visualize the distribution of problems.
This illustration clearly shows that the project manager must pay special attention to delivery delays and poor communication, as they constitute the 20% of problems that generate 80% of the difficulties in the progress of the project.
Interpreting and using the results of a Pareto table
Interpreting a Pareto chart involves identifying the issues or factors (the 20%) that have the greatest impact (80%) on a given situation. For example, in a company, this could be a small number of products that generate the majority of revenue.
The results of a Pareto chart should be used to guide actions and decisions. By focusing on optimizing the identified 20%, one can maximize the effectiveness and impact of one's efforts. However, it is crucial to re-evaluate the results regularly, as influencing factors can change over time.
The use of the results of a Pareto chart is not limited to business. This technique can be applied in various situations, such as time management or productivity improvement. In these cases, the goal would be to identify the 20% of actions or tasks that produce 80% of the desired results.
How to apply the 20/80 technique in everyday life?
Using Pareto's Law for Better Time Management
The Pareto law can be a valuable ally in improving your time management . The idea is simple: target the 20% of your activities that produce 80% of your results. This allows you to focus on what matters most and eliminate or delegate less important tasks.
To apply this method, start by making a list of all your tasks and activities. Then, identify those that produce the most results. These are the ones on which you should focus the majority of your time and effort.
- Example : If you spend a lot of time responding to emails, but it only has a minor impact on your overall productivity, you might consider reducing that time or delegating it to someone else.
- Tip : The Pareto chart can be a useful tool to visualize the impact of each task on your overall productivity.
Finally, remember that the Pareto law is only a guide. The 20/80 ratio is not always exact and can vary depending on the situation. It is not an absolute rule, but rather a general principle to keep in mind when managing your time.
Applying the Pareto Principle to Improve Productivity
To boost your productivity using the Pareto principle , it is essential to identify the 20% of actions that generate 80% of your results. These are the tasks on which you should focus your efforts.
To do this, start by making a list of all your tasks and responsibilities. Then evaluate the impact of each task on your overall goals. This will help you determine which tasks are the most productive.
It's also a good idea to use data analytics tools to consider all aspects of your work and identify the most impactful tasks.
Finally, don't forget to regularly evaluate your tasks and their impacts, as they may change over time.
The Importance of the Pareto Principle in Decision Making
The Pareto principle is of paramount importance in decision making because it allows for efficient allocation of resources by focusing on the most influential factors. For example, a team leader might use this rule to identify the team members who bring the most value to a project. Similarly, a car manufacturer might focus its efforts on improving the 20% of parts that cause 80% of failures.
It is also a valuable tool for human resource management . By identifying the 20% of tasks that generate 80% of productivity, managers can optimize the order of priority and eliminate unnecessary tasks.
In short, the Pareto Principle is an essential guide for adopting a strategic and effective approach to decision-making.
Limitations and criticisms of the 20/80 method
The 20/80 method, although useful, is not without its critics.
First, the 20/80 ratio should not be taken literally. In reality, the exact percentage can vary considerably depending on the context and situation. The fundamental error would be to consider this rule as an immutable law rather than as an empirical observation.
Second, this method can lead to an excessive reduction in the importance of certain tasks or factors, focusing only on the "20%". This can lead to neglecting elements that, although they do not contribute significantly individually, can collectively have a significant impact.
Finally, the Pareto law does not provide concrete solutions to address the identified problems. It helps to highlight areas to prioritize, but implementing effective solutions requires deeper analysis and understanding of the underlying causes.
