Don Norman — The Design of Everyday Things

1988, revised 2013

Summary:

• Focus on usability of everyday objects and why bad design causes errors.

Key Points:

• Affordances: suggest usage (e.g., push/pull doors)

• Signifiers: visual cues guiding actions

• Constraints: prevent errors by design

• Feedback: users must see results of actions

• Iterative design: test, learn, improve

• 
  

Practical Examples:

1. Push/pull door signs — show proper affordance

2. Logical light switch placement — immediate feedback

3. Stove knobs with clear markings — reduces mistakes

Quote:

"The design of everyday things should make the user’s experience simple and natural."

Alan Cooper — About Face

1995, 4th edition 2014

Summary:

• Guides on interaction design for digital products

• Focus on goal-directed design and user behavior

Key Points:

• Personas to model real users

• Scenarios for task-based design

• Consistency, feedback, clarity, efficiency

• Goal-directed design: design for user intentions

Practical Examples:

1. Persona “Frequent Shopper” guides e-commerce checkout design

2. Calendar app scenario — optimize task completion

3. Mobile app for booking tickets — streamline main flow based on persona needs

Quote:

"Design is about behavior — what the product does, not what it looks like."

Steve Krug — Don’t Make Me Think

1995, 4th edition 2014

Summary:

• Practical guide to web usability

• Emphasizes simplicity and clarity

Key Points:

• Users scan, don’t read

• Minimize thinking effort; make navigation obvious

• Usability testing is cheap and effective

• Iterative changes improve usability

Practical Examples:

1. Home page with obvious navigation categories

2. Clear, labeled buttons to avoid confusion

3. Form design with inline hints — reduces errors

Quote:

"Don’t make me think."

Jeff Gothelf — Lean UX

2013

Summary:

• Focused on fast, collaborative UX in Agile teams

• Learning through experimentation

Key Points:

• Hypothesis-driven design

• Cross-functional teams collaborate closely

• Continuous feedback and user testing

• MVP mindset: minimal versions first, iterate fast

Practical Examples:

1. Minimal prototype tested with 5 users before full build

2. Daily stand-ups to adjust design quickly

3. Rapid A/B testing for new feature interface

Quote:

"Design is a process of continuous learning, not a one-time deliverable."

Brad Frost — Atomic Design

2016

Summary:

• Framework for building modular design systems

Key Points:

• Atoms → molecules → organisms → templates → pages

• Promotes consistency, scalability, reusability

Practical Examples:

1. Button component (atom) reused in forms and nav (molecules → organisms)

2. Navigation bar (organism) used on multiple pages

3. Card component (molecule) reused in product listings

Quote:
"Atomic design creates a consistent, scalable approach to UI."
