Which of the following best describes "Card View" in Smartsheet?

Card View in Smartsheet is designed to provide a visual representation of tasks that can be organized and managed in a highly interactive manner. This view allows users to see tasks presented as cards that can easily be moved between different columns, which typically represent different stages in a workflow or project progress. This functionality is particularly useful for teams employing agile methodologies, as it allows for quick adjustments and prioritization.

The other options describe different functionalities or views within Smartsheet. A detailed grid of data entries refers to the traditional grid view, which is focused on data management rather than visual task movement. A list of users and their permissions pertains to managing access and collaboration within the system, while a summary of project costs relates to a financial overview, rather than task management. Therefore, the choice that accurately captures the essence of Card View is its emphasis on the visual organization and movement of tasks.
