4. Wireframes & User Flows
The Logic Before the Layout
Engineering a product without a wireframe is like building a house without a blueprint. Before we worry about colors or fonts, we must solve the functional journey. Wireframes and User Flows are the skeletal structures that define how a user moves from 'Problem' to 'Solution'.
📐 Wireframing: Structural Blueprints
Wireframes are low-fidelity visual representations of an interface. They use placeholders (like an 'X' in a box for images) to strip away visual distractions and focus on information priority.
- Low-Fi: Quick sketches or digital boxes focused on placement.
- High-Fi: Detailed layouts including actual content and specific button sizes.
🛤️ User Flows: Mapping the Path
A User Flow is a diagram showing the path a user takes through your product to complete a task. In professional engineering, we map these out to identify 'Happy Paths' (success) and 'Edge Cases' (errors or cancellations).
- Screens: Represented by rectangles (e.g., Login Page).
- Decisions: Represented by diamonds (e.g., Is password correct?).
🛑 Reducing Friction
Every extra step in a user flow is an opportunity for a user to leave. UX Engineering is the art of shortening this path. For example, replacing a 5-page signup form with a single-click 'Sign in with Google' button is a massive win for user retention.
In the Sandbox, you will be presented with a set of screens and decision points. Your task is to wire a complete 'Sign Up' flow. You must connect the Landing Page to the Sign Up Form, then to an Email Verification decision. You must ensure both the 'Success' path (Dashboard) and 'Failure' path (Error State) are correctly connected. A flow is only functional if the user cannot get stuck.
Wire the User Flow
Required path: Landing → Signup → Verify → (Dashboard success | Error fail)
