This philosophy is a play on the Zen of Python, in which one line states:

There should be one-- and preferably only one --obvious way to do it.

Part of how we manage complexity in our projects is by distilling things down to single sources of truth. By defining single sources of truth, we avoid the hairy situation of being unsure which version/copy of a thing we ought to depend on. This has the effect of minimizing confusion, and even potential conflicts, downstream.

As you go through the knowledge base, you will see this philosophy at play in how we structure and organize our individual projects.
