What designates what a user can do within a sheet?

The correct answer highlights the importance of sharing permissions as a critical aspect of managing user capabilities within a Smartsheet. Sharing permissions define the specific actions a user can perform on a sheet, such as viewing, editing, or managing details like settings and sharing options. By controlling these permissions, a system administrator can ensure that users have the appropriate access aligned with their roles and responsibilities, thereby safeguarding data integrity and enabling collaborative workflows.

While user type and access level also influence what users can do, sharing permissions provide the granular control needed to tailor each user's experience on a sheet-by-sheet basis. Account settings pertain more broadly to the configuration of the overall user account and organizational settings, rather than what actions are permitted within individual sheets. This distinction emphasizes the targeted nature of sharing permissions as they relate directly to a user’s interaction with specific sheets.
