1 World Usability Day Ignite! Session Fixing The Trouble with Computers: User Centered Design, Development, and Deployment Jay Edwin Gillette Center for Information and Communication Sciences Ball State University

2 Fixing The Trouble with Computers Influential books in a professional career: Thomas K. Landauer (1995). The Trouble with Computers: Usefulness, Usability, and Productivity. Cambridge, MA: MIT Press.

3 Landauer: The Trouble with Computers is bad design, bad human interface Productivity increases with computers is an unproven, overrated thesis; jury is out, though CW says it must be so  advanced by “technology experts” like Alan Greenspan; (ICT people may know better)  how many hours have you spent “saving time” using computers? The reason information & communication technology (ICT) is counter-productive is bad design [MS software]  JEG “most American business works at C level”

4 Characteristics of Design: Tom Peters “Design is...” (Examples from Essay 98 in The Pursuit of Wow! ) ,000 different things to 200,000 different people. 5. An easy-to-use FedEx airbill. 14. A visceral understanding that design is a/the way to differentiate a product or service. 21. An attitude about life. nn. [You say]...

5 Characteristics of Design--Design is: Creative Personal Social Maya Lin: “Everything you need it to be, not everything you want it to be.”

6 User-Centered Design vs. System- Centered Design User-Centered = “User-driven” design, focus on the user –What’s good for the user System-Centered design, focus is on what’s good for the system –User must adapt to the system, not system adapting to the user

7 Landauer’s Concept of UCD3 UCD3 violates the first rule of acronyms [one meaning rule] UCD3 = –User-Centered Design –User-Centered Development –User-Centered Deployment UCD3 is a cycle, with the user in common

8 Usefulness and Usability Landauer (pp ) Usefulness—does it help? Usability—how “easy” is it to use? (that is, how effectively can the user use it?)

9 User-Centered Design Methods Landauer (key Chapter 12) “This chapter says most of what needs reading before getting started. The best next step is doing. Nobody has a magic formula beyond the general kinds of activities in which to engage. Little extra knowledge is essential.” [p. 277]

10 Formative vs. Summative Design Evaluation Landauer (key section, p. 281) Formative evaluation guides changes Summative (“summary”) evaluation tests “how good” the finished system is “Iterative development = formative design evaluation”

11 Landauer’s Task Analysis Learn the Job Consult the Users Use Subject Matter Experts (SMEs) Conduct Time & Motion Studies Consult Normal Business Records
