⠿ Understand needs, define features, gather insights

The first step of prototype design is requirement gathering and analysis. Designers work closely with stakeholders to define product goals, user needs, business requirements, and design scope. This stage clarifies the core functions and interactions the prototype should present, identifying key pages and elements such as the homepage, login page, or core feature areas. By analyzing user research, competitor products, and market trends, a solid foundation for design direction is established.

⠿ Sketching & Ideation ⠿ Low-Fidelity Prototypes ⠿ User Flow Design

Next comes ideation and low-fidelity prototyping. At this stage, designers develop multiple design options based on requirements and present them through sketches or flow diagrams. Low-fidelity prototypes are usually created with simple tools such as hand sketches, Balsamiq, or whiteboards, focusing on structure and basic flows rather than visual details. User interaction flows are also outlined to simulate how users move between different pages.

⠿ Conduct Usability Testing ⠿ Analyze Feedback ⠿ Refine the Design

After the prototype is completed, user testing and feedback become essential. Designers provide high-fidelity prototypes to target users, observe how they complete specific tasks, and collect relevant data. Based on test results, usability issues such as unclear navigation or inefficient flows are identified and refined, ensuring the design better meets user needs.

⠿ Continuous Improvement ⠿ Detail Refinement

After testing is completed, the design enters the iteration and optimization phase. Designers continuously refine the prototype based on repeated feedback, with each iteration focusing on detail refinement to achieve an optimal user experience. Visual elements and interaction details are further polished to ensure the design performs reliably across different scenarios.

⠿ Developer Collaboration ⠿ Technical Review & Validation

Finally, the prototype design enters the design handoff and development support phase. Designers deliver the prototype to the development team with clear specifications, assets, and guidance to ensure accurate implementation of the design intent. Throughout development, designers remain involved in technical reviews to keep the final product aligned with the prototype, making necessary adjustments to enable a seamless transition from design to development.
