Six Sigma and other methodologies rely upon Pareto analysis to define and focus continuous improvement efforts. Although the term Pareto principle or Pareto effect has become a standard term in business and quality improvement jargon, it is often not clear when to use Pareto charts, or how to use them effectively.
More generally, the Pareto Principle is the observation not law that most things in life are not distributed evenly. It can mean all of the following things: Think about it — in a group of workers, 20 could do all the work while the other 80 goof off.
The key point is that most things in life effort, reward, output are not distributed evenly — some contribute more than others. In a perfect world, every employee would contribute the same amount, every bug would be equally important, every feature would be equally loved by users. Planning would be so easy.
Of course, this ratio can change. So Why Is This Useful? The Pareto Principle helps you realize that the majority of results come from a minority of inputs. Focus on rewarding these employees. Focus on fixing these bugs first. Focus on satisfying these customers. The examples go on.
In economics terms, there is diminishing marginal benefit. This is related to the law of diminishing returns: By the end, you are spending lots of time on the minor details. I want to give you a real example. Take a look at this awesome video of an artist drawing a car in Microsoft Paint. Take a look at how the car evolved over time: Given 5 minutes of time, he could present: The question is whether a single Level 5 is better than five Level 1s, or some other combination.
In the planning stage, it may be better to get 5 fast prototypes rather than 1 polished product. The difference between 4 and 5 is not as great as 1 and 2, or better yet, a blank drawing and 1 the time from 0: You really have to look to see the differences on the car between 4 and 5, while the contribution 1 makes is quite obvious.
Concluding Thoughts This may not be the best strategy in every case.
The point of the Pareto principle is to recognize that most things in life are not distributed evenly. Make decisions on allocating time, resources and effort based on this: Then spend 50 minutes writing about the best one.
Instead of agonizing 3 hours on a single design, make 6 layouts 30 minutes each and pick your favorite. Rather than spending 3 hours to read 3 articles in depth, spend 5 minutes glancing through 12 articles 1 hour and then spend an hour each on the two best ones 2 hours. The Pareto Principle is an observation, not a law of nature.

Introduction. When it comes to project planning, defining the project scope is the most critical step. In case if you start the project without knowing what you are supposed to be delivering at the end to the client and what the boundaries of the project are, there is a little chance for you to success.
