Wayfinding is everything that helps people navigate a building: signage, floor maps, room naming and in-app directions. In flexible offices it matters more than it used to, because nobody has a fixed desk to anchor their mental map. It is also called office wayfinding or workplace navigation; all three describe the same discipline.
Digital wayfinding rides on the interactive floor plan: book a desk and the app shows you where it is, along with where your team is sitting today. For visitors, the same map gets them from reception to the right meeting room without an escort.
