CHAPTER 2: DESIGN PROCESS

1. Interaction design

   • Idea of designing a system
   • The system can be screen-based tangible, control-interface based, or any combination of three

2. Activities in life cycle

   • Requirement specification
   • Architectural design
   • Detailed design
   • Coding and unit testing
   • Integration and testing
   • Operation and maintainance

3. usability engineering

   • usability spefication
     • usability attribute/principle
     • measuring concept and method
     • now level/worst case/planned level/best case

4. ISO usability standard 9241

   • effectiveness
   • efficiency
   • satisfaction

5. Interactive design

   • prototype
   • management issues

6. Design rules

   • Principles of usability
   • Standards and guidlines
   • Design patterns

7. principle to support usability

   • learnability
   • flexibity
   • robustness

8. design rational

   • process-oriented design rational
   • design space analysis
   • psychological

9. golden rules and heuristics

   • "broad-brush" design rules
   • useful checklist for good design
   • produce better design
   • Nielsen's 10 heuristics
   • Shneiderman's 8 golden rules
   • Norman's 7 principle

10. the RAD life cycle model

    • project initiation
    • JAD workshops
    • iterative design and build
    • evaluate final system
    • implementation review
