  • Design For Knowledge2

    1. 1. Design for Knowledge
    2. 2. Data, Information, Knowledge <ul><li>We design for movement </li></ul>From data To information To Knowledge
    3. 3. The Goal <ul><li>To go from fact </li></ul><ul><ul><li>Estimated portion of all U.S. nuclear waste that Nevada's Yucca Mountain dumpsite will hold when it is full in 2046 : 3/5 </li></ul></ul>
    4. 4. The Goal <ul><li>To meaning </li></ul><ul><ul><li>Estimated portion of all U.S. nuclear waste that Nevada's Yucca Mountain dumpsite will hold when it is full in 2046 : 3/5 </li></ul></ul><ul><ul><li>Richter-scale magnitude of an earthquake last June twelve miles from the Yucca site : 4.4 </li></ul></ul>
    5. 5. Missing information is expensive <ul><li>Recently in the news, government’s information management problems </li></ul>
    6. 6. Missing information <ul><li>“ Like all primary care physicians, Dr. Bob Goldszer must stay on top of approximately 10,000 different diseases and syndromes, 3,000 medications, 1,100 laboratory tests, and many of the 400,000 articles added each year to the biomedical literature. That's no easy task. And it is, quite literally, a matter of life and death. The Institute of Medicine's 1999 report, To Err Is Human, suggests that more than a million injuries and 90,000 deaths are attributable to medical errors annually . Something like 5% of hospital patients have adverse reactions to drugs, another study reports, and of those, 43% are serious, life threatening, or fatal. Many knowledge workers have problems similar to Dr. Goldszer's (though they're usually less life threatening). No matter what the field, many people simply can't keep up with all they need to know.” </li></ul><ul><li>--Harvard Business Review, Jul 1, 2002 </li></ul>
    7. 7. Missing information <ul><li>Lost sales– </li></ul><ul><li>Expensive support— </li></ul><ul><li>Duplicated effort-- </li></ul><ul><li>Lost trust– </li></ul><ul><li>Lost lives? </li></ul>

    9. 9. From fact to meaning <ul><li>The right information at the right time in the right way </li></ul><ul><ul><li>Find information </li></ul></ul><ul><ul><li>Understand information </li></ul></ul><ul><ul><li>Use information </li></ul></ul>

    11. 11. Information Architects specialize <ul><li>In Information Architecture– duh! </li></ul>
    12. 12. Information Architects <ul><li>What is IA? </li></ul><ul><li>AIfIA definition </li></ul><ul><ul><ul><li>The structural design of shared information environments. </li></ul></ul></ul><ul><ul><ul><li>The art and science of organizing and labeling web sites, intranets, online communities and software to support usability and findability. </li></ul></ul></ul><ul><ul><ul><li>An emerging community of practice focused on bringing principles of design and architecture to the digital landscape. </li></ul></ul></ul>
    13. 13. Findability
    14. 14. In the physical world <ul><li>Things that have fixed locations </li></ul><ul><ul><li>We find with maps and signs-- wayfinding </li></ul></ul><ul><li>Things that don’t </li></ul><ul><ul><li>We find with organization and wayfinding </li></ul></ul>
    15. 15. In the digital world <ul><li>Nothing is fixed </li></ul><ul><li>Wayfinding and organization is the two keys to findability </li></ul><ul><li>Role of IA is to shape the digital space to enable findability. </li></ul>

    37. 37. Design for knowledge <ul><li>Information must be findable by seekers </li></ul><ul><li>Information must be found when relevant </li></ul><ul><li>Information must be presented in a meaningful way </li></ul><ul><li>Everyone must be an information architect. </li></ul>
    38. 38. Design for knowledge <ul><li>“ Now when Dr. Goldszer orders medicine or a lab test, the order-entry system automatically checks his decision against a massive clinical database as well as the patient's own medical record. Knowledge workers in other fields could likewise benefit from a just-in-time knowledge-management system tailored to deliver the right supporting information for the job at hand. ” </li></ul>
