Internal Communication
Internal communication treats the people inside an organisation as an audience with its own needs rather than as a group that will absorb whatever is sent to customers. It is the desk most often given the least time and the one whose failures surface fastest.
There is no single internal audience
An organisation with an office, a shift-based site and a field workforce has three audiences with different working hours, different access to a screen and different tolerances for being messaged. A message that lands on an office desk at nine in the morning may reach a shift worker three days later or not at all. Mapping who is reachable through what, and when, is the first piece of work on this desk and it is usually the piece that gets skipped.
Channel and cadence
Most organisations have more internal channels than they need and less rhythm than they should. A predictable cadence, where people know that a particular kind of information arrives at a particular time through a particular channel, does more for comprehension than adding another platform. Channels are worth retiring deliberately; leaving an unused intranet page in place teaches people that internal information is unreliable.
The manager cascade
Cascading a message through line managers works when managers are briefed first, given the reasoning rather than only the wording, and told what they are allowed to say when asked a question the briefing did not cover. It fails when managers learn the news at the same moment as their teams, because the manager is then a bystander rather than a source. The gap between briefing managers and telling everyone else is measured in hours, not days.
Listening is part of the job
Internal communication that only broadcasts eventually stops being read. Simple return paths, whether a moderated question channel, a short regular survey or scheduled sessions where questions are answered in public, tell the practitioner what was actually understood. Questions that keep recurring are a fault in the original message, not a fault in the audience.
