Orientation systems are often equated with signage and are usually only considered after the main planning tasks have already been completed. For the information designer, there is often little choice but to deal with the architectural requirements. However, a more sensible approach would be an interdisciplinary planning process. What must the architect consider, and what about the designer? How can the hierarchy of traffic flows and thus the systematics of guiding through the building be taken into account at an early stage, and what does this mean for the design? The publication familiarizes planners with the complex conception of guidance systems through a comprehensive foundational section and explanatory practical examples. It serves as a guide from defining requirements to process planning and successful implementation.
