A wayfinding screen is judged on whether it is right. Decide who owns the directory, where the master copy lives, and how a tenant move, a renamed department or a closed lift reaches the screen. We scope an editing tool or a data import so that your own staff can make routine changes without a developer. Redrawing maps for a new floor or building is design work.
Multilingual content multiplies the upkeep. Every label, destination and instruction has to be translated and maintained in each language, and longer words or right-to-left scripts affect the layout. Start with the languages your visitors actually use.
