  1. Multimedia Specification Design and Production 2013 / Semester 2 / week 7 Lecturer: Dr. Nikos Gazepidis gazepidis@ist.edu.gr * Notes by Dr Trevor Baker from UH

  2. Information Architecture • Learning outcomes • Defining Information Architecture (IA) • Understanding Information Environments • Components of an information architecture • Methodology & Deliverables 2

  3. Information Architecture • Information • from Latin “informatio” (outline, concept, idea) • or “informare” (to shape, form, train, instruct, educate) 3

  4. Information Architecture Information Information is form. 4

  5. Information Architecture InformationInformation is form that shapeswhatis inyour mind. Form=Idea=Seeing The old Greek word for “form” is“idea” (“eidós”). Information=Form=Idea Seeing the form: getting the idea Evolve the form: develop the idea Clear form: clear idea Clear idea: clear form 5

  10. Information Architecture • Understanding IA • This concept is very useful in designing interactive systems • Used in early stages of prototyping • Used as an object of communication • Used in evaluation • Used in story-boarding 10

  11. Information Architecture • Classification • Basis of all information architecture is the classification of: • Content • User • Very difficult to establish exclusive categories 11

  12. Information Architecture • AI System Components • Content • Organization systems • Navigation systems • Search systems • Labeling systems 12

  13. Information Architecture • Definition of Information Architecture • …is defined by the Information Architecture Institute as: • The structural design of shared information environments. • The art and science of organizing and labeling web sites, intranets, online communities and software to support findability and usability. • An emerging community of practice focused on bringing principles of design and architecture to the digital landscape. 13

  14. Information Architecture A visual definition QUESTIONS • Users • Audience types • Information needs • Business Context • strategy • resources • culture/politics • workflow Info. Architecture org, label, nav &searching systems • Content • scope & volume • structure • metadata ANSWERS 14

  15. Information Architecture Why is IA difficult? Example Personal Digital Assistant Synonyms Handheld Computer "Alternate" Spellings Persenal Digitel Asistent Abbreviations / Acronyms PDA Broader Terms Wireless, Computers Narrower Terms PalmPilot, PocketPC Related Terms WindowsCE, Cell Phones USERS Communication chasm documents & apps 15

  16. Information Architecture Why is IA important? • Cost of finding (time, clicks, frustration, precision). • Cost of not finding (success, recall, frustration, alternatives). • Cost of development (time, budget, staff, frustration). • Value of learning (related products, services, projects, people). 16

  17. Information Architecture A user’s perspective? email Notes DB Personal Network & Colleagues Shared LAN Drives Printed resources Special apps Other resources Public websites Intranets 17

  18. Information Architecture Information Environment? Business models & goals, corporate culture, resources Business Context information needs, audience types, expertise, tasks Users Content document types, objects, structure, attributes, meta-information 18

  19. Information Architecture Information Environment: Context Business Context Characteristics of Large Companies Increasingly global / distributed enterprises Multiple cultures and languages Complicating Factors (Intranets & Web Sites) Authors and users spread across departments Ownership unclear Balance of centralization versus decentralization unclear 19

  20. Information Architecture Information Environment: Users Complex and Diverse information seeking behavior, needs, expertise Users Many Ways to Study observation, interviews, modeling, testing, tracking, observation 20

  21. Information Architecture Information Environment: Content Text, PPT, XLS, HTML, XML, MS Office, Notes Print Documents, Oral Communication, Memory, PCs, Folders Financial Sales, Oracle Sybase Mainframe Content Unpublished & Tacit knowledge Data store Document store 21

  22. Information Architecture Why is IA difficult? Interested public Suppliers Customers Partners employees USERS Users cannot find the information they need Users access the right information on right time documents & apps documents & apps 22
