The organization of the display network should reflect an obvious logic based on task requirements and be readily understood by users.
Additional Information:
The structure of the interface and its associated navigation aids should make it easy for users to recognize where they are in the data space and should enable them to get rapid access to data not currently visible (e.g., on other display pages). The way the system works and is structured should be clear to the user. One way of providing a logical, explicit structure for the display network is by providing a consistent hierarchical organization. When each major branch of the network has the same, corresponding set of descendant branches, users can apply their understanding of the layout of one branch to predict how information is organized in similar branches of the network.
