In technology, a new product often involves a complete new approach to a problem that did not exist before. Benefits impact on multiple fronts: it makes things cheaper, faster, or all of a sudden you can combine things, do things differently. The story is far more complicated than "this car now runs at y liters gasoline per 100 km versus x".

The tendency of a company insider is to create a chart that explains everything. It is a bit like 5 people speaking at the same time, each expressing one nuance of the story.

1. Skill level one: write out the entire story in verbal bullet points
2. Skill level two: craft some sort of visual diagram that brings it all together

The diagram works for people who understand the story already, all the elements of the story are now in one concise page. Every element of the diagram is a visual reminder that unlocks a full story in the viewer's head. 

The fresh audience does not have this background. The only way to tell the story is isolate what is really important, and design charts specifically around that. Then, if you have to, you can construct a page that ties it all together, after the audience had a change to grasp the individual components.
