   • The goal is to create a comprehensive list of features and specifications that the product should fulfill.
3. User Experience (UX) Design:
   • UX designers create wireframes, mockups, and prototypes that outline the user interface (UI) and interaction design.
   • User flows and user journeys are defined to ensure intuitive and efficient user experiences.
   • Consideration is given to how users will interact with the product and how their needs will be met.
4. Visual Design:
   • Graphic designers work on the visual elements of the product, including color schemes, typography, icons, and branding.
   • The aim is to create a visually appealing and cohesive design that aligns with the product’s identity and resonates with the target audience.
5. Information Architecture:
   • Information architects structure the content and information within the product.
   • This involves organizing data, content hierarchy, and navigation to ensure users can easily find and access relevant information.
6. Interaction Design:
   • Interaction designers focus on how users will interact with the product’s interface elements.
   • They define behaviors, animations, transitions, and micro-interactions that enhance the overall user experience.
7. Prototyping and Mockups:
   • Detailed interactive prototypes or mockups are created to visualize the product’s design and functionality.
   • These prototypes help stakeholders and development teams better understand the final product’s look and feel.
8. Design Validation and User Testing:
   • Design concepts and prototypes are tested with real users to gather feedback and identify potential issues.
   • User testing helps validate design decisions and uncover usability problems or areas for improvement.
9. Iterative Design Refinement:
   • Based on user feedback and testing results, the design is refined and iterated upon.
   • Adjustments are made to address any usability issues, optimize user flows, and enhance the overall user experience.
10. Design Documentation:
    • Detailed design specifications, style guides, and design documentation are created.
    • These documents provide developers with clear guidelines on how to implement the design and maintain visual consistency.

The design stages of the PDLC are critical for ensuring that the product’s user interface, functionality, and overall experience align with user needs and business goals.
