  13. What is this course about?

  14. Information System Design? • Three abstract words • information • system • design • Question? • What does design mean to you?

  15. Design Method • Activity • A procedure that leads toward a final solution • Form • Document, sketch, model, conversation, etc. • Process • The output of a design method becomes the input to the next step

  16. Examples • Brainstorming session • User scenario • Task analysis • Competitive audit • Marketing requirements document • Wireframe sketch • many, many others…

  17. The objective • An information system that fulfils human needs • How do you know? Usability… • ISO Definition The effectiveness, efficiency, and satisfaction with which specified users achieve specified goals in particular environments

  18. Definition of usability • From Nielsen (p. 26) • Learnability • Efficiency • Memorability • Errors • Satisfaction

  19. Many more factors, of course • Usefulness • Versatility • Pleasurability • Values • It makes money…

  20. Designing usable information systems is very hard Case of the Gatorade bottles

  21. Key features • Patented lip cap • Based on an anthropometric study of lip size and shape • Grip zone • Based on hand sizes (5th – 95th percentiles) • Contours • Based on finger sizes • See http://www.metaphase.com/portfolio_04.html

  22. Observations • Details matter • Good designs are ‘transparent’ • To get it right, takes research, trial-and-error, and a lot of work • What about a watch, an encyclopedia, a website, or other information system?

  23. Quick overview of assignments

  24. Deliverable guidelines • Standard cover sheet • Standard formatting • Grading guidelines • Late policy • Re-grading policy *See website for details

  25. Assignments • Design exercises (4 assignments) • Studying artifacts • Organize facts and deriving concepts (group) … • Interactive prototype project • Quarter-long, individual work • Four intermediate deliverables • Final deliverable: 13 December

  26. Assignments (cont.) • Weekly quizzes • 20min • Short answers • Participation • Ask questions, give answers • Show work, accept criticism • Develop an on-line journal (more later)
