When developers need to delete published apps, what should a system administrator do?

The correct action for a system administrator when developers need to delete published apps is to disable the default security rule preventing this action. In Qlik Sense, security rules are defined to control access and actions that users can perform within the environment. By default, certain actions, such as deleting published apps, might be restricted to ensure governance and proper data management.

Disabling the default security rule allows for a more flexible access model where specific user roles, such as developers, can manage apps more effectively without having to elevate their permissions unnecessarily. This method is operationally efficient as it directly addresses the need while maintaining a level of control over app management permissions.

The other options, while they may seem relevant, don't directly resolve the issue of allowing developers to delete published apps. Granting root admin rights could lead to security risks as it gives developers too much control over the system. Creating a custom property would require additional configurations and may not directly grant the necessary permissions. Providing documentation on app deletion, while helpful, doesn't facilitate the actual capability to perform the deletion. Thus, adjusting the security rules is the most suitable and efficient solution.
