Design-Informing Models

Hartson and Pyla (ch. 6, ch. 9 in 2nd edition) provide a rich space of conceptual design approaches under the umbrella term Design-Informing Models

User Models

  • Work roles
  • User classes
  • User personas

Usage Models

  • Flow models
  • Task models
  • Information object models

UX-oriented models (my characterization)

  • Social models (user model)

Environment models

Hartson and Pyla discuss diverse approaches to describe physical environment and artifacts in the environment.

Issues for discussion

  • What are advantages to listing barriers from the design-informing models?
  • How well can personas with scenarios capture what these design-informing models represent?
  • How do you choose which models to use?
