Key UX & Usability Insights from NN/G

• AI in UX:
  • AI agents require discoverability, familiar patterns, data privacy, and user autonomy.
  • Helpful AI chatbots should state capabilities, suggest prompts, and provide context awareness.
  • AI should act as a "thought partner" in research analysis, but human critical thinking must remain in control.
• UX Strategy & Stakeholders:
  • Stakeholder friction is often structural; address it through direct user observation, streamlined involvement, and intentional management of competing goals.
• Core UX Methodologies:
  • Heuristics: Jakob Nielsen’s 10 principles are broad rules of thumb, not specific guidelines.
  • Empathy Maps: Used to align teams on user attitudes and identify data gaps.
  • Usability Testing: Avoid elaborate tests; testing with 5 users is more efficient and effective.
  • User Interviews: Best for understanding user perceptions, not for testing usability.
  • Card Sorting: Essential for creating information architecture that aligns with user expectations.
  • Design Thinking: A 6-phase, user-centric approach to problem-solving that drives innovation and competitive advantage.
• Process & Planning:
  • User Journeys vs. User Flows: Distinct tools with different scopes and purposes for mapping user goals.
  • Research Methods: 20 methods are categorized by 3 dimensions to help teams choose the right tool for specific product-development stages.
• Critique: Modern design updates (e.g., iOS 26) often prioritize new patterns over established conventions, sometimes obscuring content.
