What is the purpose of the Mockup UI tab in a story card?

The purpose of the Mockup UI tab in a story card is to show the proposed user interface for the story. This visual representation helps stakeholders and team members understand how the final product will look and function. It can include wireframes, design layouts, or any other relevant visuals that depict the user experience. By providing a clear and concise mockup, the team can effectively communicate design ideas and gather input or feedback before proceeding with development. This early visualization is crucial for aligning the team on the design direction and ensuring that the user interface meets the needs of the end users.

In contrast, the other options focus on different aspects of project management or development. Listing project stakeholders is important for understanding who is involved, detailing technical implementation focuses on how the system will be built, and providing a timeline is essential for planning and ensuring project milestones are met. However, none of them pertain to the visual representation of the user interface, which is the primary function of the Mockup UI tab.
