Divergence and convergence are not a linear path, but a loop: once you complete one round of convergence, you can take what you’ve learned right back into a new cycle of divergence. Keep alternating back and forth, making iterations each time until it’s something you can consider “done” or “complete” and share more widely.

Convergence forces us to eliminate options, make trade-offs, and decide what is truly essential. It is about narrowing the range of possibilities so that you can make forward progress and end up with a final result you are proud of. Convergence allows our work to take on a life of its own and become something separate from ourselves.

The easiest way to understand convergence is to think of it as the overlapping space between what you care about and what other people are willing to spend money on.

In biology, convergence refers to the process wherein organisms evolve analogous traits that were not present in their last common ancestor. In other words, species that are not closely related to each other will find the same solutions to the same problems in their quest to survive.

Divergence and Convergence
David Ehrlichman • Impact Networks: Create Connection, Spark Collaboration, and Catalyze Systemic Change
To create an Archipelago of Ideas, you divergently gather a group of ideas, sources, or points that will form the backbone of your essay, presentation, or deliverable. Once you have a critical mass of ideas to work with, you switch decisively into convergence mode and link them together in an order that makes sense.
