Flow Chart on Steroids
The left side of this PowerPoint slide on customer lifetime value in service contracts
does pretty well (If you overlook the iffy capitalization, the wacky punctuation, and the inconsistent framing of the “Modeling issues”): The text is in short bullet points, colours and fonts are restrained, and the presenter used a basic slide template (when in doubt, use a template!).
But then we get to the flow chart. Presumably the red arrows are there to explain what’s going on in the maze of black arrows. The red arrows are somewhat helpful, except for the jarring overlay of red on black. As for the 10,000 black arrows, they probably make a point, or something, but really?
