What should be evaluated if users can create an account record without filling a required field?

When users can create an account record without filling a required field, evaluating field-level security is crucial. Field-level security determines the visibility and editability of individual fields on an object. If field-level security settings are not configured correctly, users may be able to bypass required fields when creating or editing records. For a required field to function as such, it must be set not only as required at the object level but also need to be appropriately enforced through field-level security settings. If a user does not have access to see a required field, the system may allow the record creation without requiring that field to be filled out.

Understanding this principle is vital because it ensures that the fields intended to be mandatory for data integrity and compliance are enforced in all aspects of the application, including user permissions. This helps maintain the quality of data collected in the system, underpins effective reporting, and supports compliance with industry standards.
