The 80/20 rule, also known as the Pareto principle, is a popular quality improvement tool that states that 80% of the effects come from 20% of the causes.
The 80-20 rule, also known as the Pareto Principle, is a familiar saying that asserts that 80% of outcomes (or outputs) result from 20% of all causes (or inputs) for any given event.
The Pareto Chart is a very powerful tool for showing the relative importance of problems. It contains both bars and lines, where individual values are represented in descending order by bars, and the cumulative total of the sample is represented by the curved line.
The Pareto Rule is a powerful tool that can help you improve your project management efficiency. By focusing on the 20% of activities that generate 80% of the results, you can make significant progress on your projects while spending less time on less important tasks.
As one writer explores on his blog, the Pareto Principle applies directly in software engineering in the following ways: 80% of bugs come from 20% of the features. 80% of the complexity in an application comes from 20% of the code base. 80% of an engineering team's time is spent on 20% of the application.

What is the 80-20 rule in program management?
When applied to project management, the 80/20 rule asserts that completing the 20% of tasks that are most urgent will drive 80% of the results. In other words, out of ten tasks your team must complete, two are more important than the others.
It suggests that a small percentage of causes is responsible for a large percentage of effects. In trading, this means that approximately 80% of returns are expected to come from 20% of trades or trading strategies. Conversely, the remaining 80% of trades may only generate 20% of total returns.
Project Managers know that 20 percent of the work (the first 10 percent and the last 10 percent) consume 80 percent of the time and resources. Other examples you may have encountered: 80% of our revenues are generated by 20% of our customers. 80% of our complaints come from 20% of our customers.
According to 80/20, they named their company and product line after Pareto's Law (from Vilfredo Pareto (1843 – 1923)), an Italian economist and sociologist who said that 80% of your results come from 20% of your efforts.
In transportation, 80% of the delays might result from 20% of the possible causes. In business, 80% of the revenue might come from 20% of the customers or 20% of the products. In a manufacturing process, 80% of the downtime might result from 20% of the problems.
Simply put, the 80/20 rule states that the relationship between input and output is rarely, if ever, balanced. When applied to work, it means that approximately 20 percent of your efforts produce 80 percent of the results.
How does it work? Let's do the math. If 80% of 80% of business comes from 20% of the 20% of the customers, it's (0.80 x 0.80) / (0.20 x 0.20). This means that 64% of business comes from 4% of the customers.
It boils down to a simple statement which can be adapted to your business model: Companies should focus on the 20% of inputs that create the majority (80%) of their outputs.
The Pareto principle (also known as the 80-20 rule, the law of the vital few, and the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes. From a business vantage, "80% of your sales come from 20% of your clients".
Plot the Pareto Chart: With your data prepared, you're ready for the fun part - making the Pareto chart. Select your data (categories, values, and cumulative percentage), go to the 'Insert' tab, and under the 'Chart' group, click on 'Statistical', then select 'Pareto'.
Summary. The Pareto principle (also known as the 80/20 rule) is a phenomenon that states that roughly 80% of outcomes come from 20% of causes. In this article, we break down how you can use this principle to help prioritize tasks and business efforts.
The 80/20 rule in business states that 80% of your results come from 20% of your efforts. For example, a company may find that 80% of its revenue comes from 20% of its customers, so it may choose to focus its efforts on serving and retaining those key customers.
The 80/20 rule is a guide for your everyday diet—eat nutritious foods 80 percent of the time and have a serving of your favorite treat with the other 20 percent. For the “80 percent” part of the plan, focus on drinking lots of water and eating nutritious foods that include: Whole grains.
The 80/20 rule, also known as the Pareto principle, is a popular quality improvement tool that states that 80% of the effects come from 20% of the causes. For example, 80% of the customer complaints may be caused by 20% of the defects.
The Pareto Principle, also known as the 80/20 rule, is popular in various industries, including software development. The idea is that 20% of developers' time is spent on work that results in 80% of the value created.
To set goals with the 80-20 rule, you primarily establish that 20% of your efforts/tasks will result in 80% of your results. For example, at work, 20% of the effort you put into your job will result in 80% of your tasks being completed/successful.
Within a specific system or process, Pareto teaches us to recognize the difference between the vital few (20%) variables or details, and the trivial many (80%). Give the most attention to improving your weak links and removing bottlenecks! The Pareto Principle is sometimes known as the Law of Least Effort.
The 80/20 rule is handy when thinking about code quality and debugging issues. We can apply the Pareto Principle to quality control, as 80% of bugs can be found in 20% of the code. If 80% of bugs lead back to the same lines of code, that should signal to programmers that those lines require additional attention.
This rule suggests that 80% of your project's success comes from 20% of your efforts. Here's how to use it: Identify key tasks: Look for the 20% of tasks that will have the biggest impact on your project. These could be crucial design elements or stages that define the project's success.
