Why might a provisioning request be skipped when an account already exists?

The reason a provisioning request may be skipped when an account already exists is primarily related to the concept of access management. If a user already possesses the necessary access rights or permissions related to a specific application or resource, the system recognizes that no additional provisioning is needed. Thus, it avoids creating duplicate access, which could lead to conflicts or confusion in the access rights assigned to that user.

This approach ensures that users do not receive redundant entitlements, which can complicate access management frameworks. Efficient identity governance practices emphasize maintaining a clean and precise access list, ensuring that users only have the privileges they require to perform their roles. In this scenario, recognizing existing access prevents unnecessary duplication and adherence to the principle of least privilege, where users are granted the minimum levels of access necessary to perform their job functions.

The other options, while they address valid concerns, do not capture the direct relationship between existing user access and provisioning requests as effectively.
