Lesson 1
Product design defines workflows, information, states, and interaction; visual design shapes the appearance and emphasis of that structure. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 2
A user journey maps the steps, decisions, information, and emotional friction between a user's starting point and intended outcome. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 3
A wireframe is a low-detail representation of page structure, content priority, controls, and navigation without final visual treatment. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 4
Page hierarchy is the deliberate ordering and emphasis that tells a user what the page is, what matters, and what to do next. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 5
A form collects structured input; validation checks whether it is acceptable; feedback explains what happened and how to proceed. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 6
Interface states explain what the system is doing when data is pending, absent, completed, or unavailable. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 7
Responsive design adapts content, controls, and layout to different viewport sizes and input conditions without losing meaning or function. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 8
Accessibility means designing information and interaction so people with varied visual, motor, hearing, or cognitive needs can use the product. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 9
A design system is a maintained set of reusable interface decisions, while components are the implemented building blocks that express them. Learn the founder decision, practical evidence, and warning signs that matter.
Lesson 10
Reviewing an AI-generated interface means evaluating its workflow, states, accessibility, responsiveness, and maintainability beyond visual plausibility. Learn the founder decision, practical evidence, and warning signs that matter.
