I believe the org chart is one of the three critical artifacts that must be easily discovered and well-maintained. Why? First, let’s start with a definition. In my favorite part of Managing Humans, the glossary, I define an org chart as:
A visual representation of who reports to whom. Org charts are handy in large organizations for figuring out who you’re dealing with.
That’s one good use case, but one is missing. An org chart should also effectively describe, at a high level, how the product is organized and also who is responsible for what. An org chart should be legible.
