When is it appropriate to use a patch in an application?

Using a patch in an application is typically appropriate when you need to deploy incremental changes to your environment. Patches allow developers to make updates or modifications that improve functionality, fix bugs, or enhance performance without the need for a complete overhaul of the application. This approach is beneficial in environments where continuous improvement is a priority, as it minimizes disruption and allows for rapid iteration based on user feedback or changing requirements.

In contrast, adding new users to the application typically does not involve a patch; it is more related to user management and system administration. Deleting unused application objects can also be handled through different means, such as regular maintenance tasks rather than through a formal patching process. Performing a complete application upgrade is a larger effort that typically involves more significant changes than what a patch would encompass and often requires different protocols to ensure all elements of the application are properly updated. In summary, the incremental nature of patches makes them suitable for targeted updates, affirming the appropriateness of option B.
