11 info architecture-2014

  1. 1. Today’s objectives: 1. Explain the 3 questions that navigation must answer at all times 2. Apply the 3 questions to critique existing interfaces 3. Define “Information Architecture” (IA) 4. Recognize and create IAs using different organization logics (task-based, audience-based, topical, life-event, etc.) 5. Solve IA problems using card sorting
  2. 2. Main points  What is IA?  How do you represent IA in documents?  Card sorting  Topology: Breadth vs. Depth  Organization logics: task-based, user type, topical, org. structure, life event, implementation from BGW 5
  3. 3. http://webstyleguide.com/wsg3/3-information-architecture/4-presenting-information.html Information Architecture
  4. 4. http://webstyleguide.com/wsg3/3-information-architecture/4-presenting-information.html Information Architecture File naming > URL design! http://www.slideshare.net/deanna.marbeck/url-design-for- information-architects-presentation
  5. 5. Why does information architecture matter? *
  6. 6. Organize available information to support the user’s tasks.
  7. 7. How people navigate  Optimal rationality  Satisficing (Information Foraging Theory)
  8. 8. How people navigate Benefit Cost
  9. 9. Navigation costs  Scanning page  Reading links / menus  Finding / Deciding where to click  Waiting for page to load  Clicking through to find desired page How can you minimize them?
  10. 10. Broad Structure Deep Structure
  11. 11. Breadth & Depth Design Recommendations  Magic number 7 ± 2 ????  Recommended depth: 3 levels  Recommended breadth: 16 options
  12. 12. Organization Logics  Semantics (conceptual)  Task-based  Audience-based (user type)  Organization-based  Life event  Implementation  See also http://wd.onepotcooking.com/2010/02/13/information- architecture-navigation/
