  2. requirements analysis: task analysis, cognitive modeling
  3. design generation: mockups, information architecture, prototyping, brainstorming
  4. design evaluation: user testing, usability inspection, walkthroughs
  5. production: style guides, user interface toolkits, iterative design
  6. validation: field testing, alpha/beta testing, competitive user testing, stress testing
