Should you also change the signage?
Yes, if the door sign, the directory or the arrow still carry the old name or the old colour. You do not need to remake interior wayfinding if only a menu detail changed and the visitor already finds the room. Walk from the street to the counter and photograph every sign. Mark the ones that contradict the new mark. In Madrid buildings the mailbox and the directory keep the previous name. The patient rings someone else's bell. The list of signs to replace, with measurements and a one-ink file for the signmaker. They go up in the same phase as the door, not the following quarter.
