Internal communication
How you communicate & with what tools
How information moves inside the organization determines how well people can actually do their work, and most teams have never mapped it deliberately.
Internal communication is not just which tools the organization uses. It is the norms around those tools: what gets sent where, who is expected to respond and how fast, what is broadcast versus what is a conversation, and what should never be in a chat thread at all. Without those norms being explicit, people fill in the gaps with their own assumptions.
Most communication problems are not about the wrong tool. They are about unclear expectations: who needs to know what, when is a response required, and where does a decision get documented after it is made. Getting those questions answered and written down reduces noise and prevents important things from falling through the cracks.
Documenting internal communication does not mean creating a rulebook. It means capturing enough of the current approach that a new person can orient themselves quickly and that the team can have a real conversation when the approach is not working.
