What is UI Structure?

The aggregate of all underpinning conceptual relationships of a user interface defines its structure. [1] UI structure is created when the aggregate of concepts and content is systematically defined to provide a sound reference architecture for UI design, conceptual data models, and technical functionality. [2]

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.

These descriptions provide an important lens that gives focus to the UI engineering activities needed in the design of complex digital user interfaces. As a result, UI structure helps to align a range of digital disciplines, including but not limited to: 

  • Experience & Interaction Design
  • Content Strategy & Publishing
  • Design Systems & Accessibility
  • Navigation, Labeling, Search, and Organization Systems
  • Product & Business Architecture
  • Data Architecture
