The Pareto Principle (also known as the 80/20 rule), named after esteemed economist Vilfredo Pareto, specifies that 80% of consequences come from 20% of the causes. This principle serves as a general reminder that the relationship between inputs and outputs is not balanced.
The Pareto Chart is useful to observe this principle and helps to focus the efforts for maximum benefit.

Collaboration is usually done via email where information can get lost and is hard to find leading to your inbox being overwhelmed with old messages. This is especially true for Excel add-ins as it is the only way to share information for these applications.
Leave inbox clutter behind as each user can go into the charts (provided that they have access to it) and comment, leave a message, feedback or ask questions leading to a collaboration. As all material is in one place, this makes it easier to find relevant information.
