Organizational design to support usability
Carroll & Rosson (1985) Characterization :
1. Design is a process
2. Non-hierarchical
3. Radially transformational
4. Discovery of new goals
Three Pillars of Design
1. Guidelines documents & processes
2. User-interface tools
3. Expert reviews & usability testing
