When you create an illustration of the flow of user actions in a given scenario, what planning task are you performing?

When you create an illustration of the flow of user actions in a given scenario, you are effectively sketching a storyboard. A storyboard is a visual representation that outlines the sequence of events and interactions a user might have within a system. This planning task helps in visualizing the user experience and understanding the narrative of how users will engage with the application.

By using a storyboard, developers and designers can clearly communicate the intended user interactions, identify potential challenges, and refine the user journey before actual development starts. It serves as a crucial tool for ensuring that all stakeholders have a shared understanding of the user flow, which can inform further design and development decisions.

While establishing a use case involves documenting the requirements or goals of the system from the user's perspective, and wireframes focus on the layout and structural design of the application, these are distinct from a storyboard's emphasis on user interaction flow. Likewise, mockups are detailed designs of the interfaces, often without the narrative context provided by a storyboard.
