Pareto principle (80-20 rule) applied to different domains

 Sales and Marketing: The Pareto Principle states that 80% of sales come from 20% of customers. This means that a small group of customers generates a significant portion of a company's sales. To maximize profits, a company should focus its efforts on retaining and nurturing its most valuable customers.

Project Management: The Pareto Principle states that 80% of project results come from 20% of the project tasks. This means that a small number of tasks can have a major impact on the outcome of a project. To maximize efficiency, a project manager should focus on prioritizing and completing the most critical tasks first.

Manufacturing: The Pareto Principle states that 80% of defects come from 20% of the production process. This means that a small part of the production process is responsible for the majority of defects. To improve quality, a manufacturer should focus on identifying and fixing the root cause of defects in this part of the process.

Software Development: The Pareto Principle states that 80% of bugs come from 20% of the code. This means that a small portion of code is responsible for the majority of bugs. To improve the quality of software, developers should focus on identifying and fixing the root cause of bugs in this part of the code.

Supply Chain: The Pareto Principle states that 80% of inventory is consumed by 20% of products. This means that a small number of products consume a large portion of inventory. To optimize inventory management, a company should focus on tracking and managing the inventory of its most popular products.

Health Care: The Pareto Principle states that 80% of medical expenses come from 20% of patients. This means that a small group of patients generates a significant portion of a health care provider's expenses. To control costs, a health care provider should focus on providing preventative care and managing the care of its most expensive patients.

Customer Service: The Pareto Principle states that 80% of customer complaints come from 20% of customers. This means that a small group of customers generates a large portion of customer complaints. To improve customer satisfaction, a company should focus on addressing and resolving the complaints of its most frequent complainers.

Human Resources: The Pareto Principle states that 80% of employee performance comes from 20% of employees. This means that a small group of employees generates a large portion of a company's performance. To improve productivity, a company should focus on developing and retaining its most high-performing employees.
