Can you explain the principle of Pareto's law and its impact on resource distribution or efficiency?

The Pareto principle, or the 80/20 rule, states that approximately 80% of results are achieved with 20% of efforts or resources. This empirical observation is often seen in business, economics, and time management.

For example, 20% of clients may generate 80% of the profit, or 20% of program features are used in 80% of cases. This helps focus resources and efforts on the most important aspects for maximum efficiency.

In resource allocation practice, this means identifying and supporting the key 20% that have the main effect, instead of evenly distributing efforts across all areas.
