What is UI Structure?
The aggregate of all underpinning conceptual relationships of a user interface defines its structure.  UI structure is created when the aggregate of concepts and content is systematically managed to provide a sound reference architecture for UI design, conceptual data models, and technical functionality. 
UI Structure Contributes to Alignment
UI structure is rooted in information architecture theory and science. It is associated with the following DSIA-based concept, which describes an information architecture (work product) as:
- The assumptions and governing constructs for assigning properties and attributes to information and the endowment and evolution of information relationships over time within a given domain.
- A governing model for information behavior within a digitally mediated environment.
- The governing framework for content behavior.
Before a structure can be systematized, it must be designed. This is often expressed as an information model. The structural design for a user interface or other shared information environment often includes the consideration of systems for navigation, labeling, search, organization, and semantics. The following is a list of example conceptual models used in the design of UI structures.
- Business & Organizational Models
- Content Models
- Controlled Vocabularies
- Flow Models
- Object Models
- User Models
- Site Maps
