Summary

In a complex application decisions have to be made whether a person is allowed to perform a certain action. For example in a DCM application for mortgage applications. Based on the current application the system has to decide whether the Junior Mid-Office employee is allowed to make the approval decision, or if a more senior role is needed. The stakeholders may decide that any property with a value under half a million can be done by junior employees, while anything above has to be done by a senior employee. This logic can be much more complex as in this example.

As the user permission example does not concern the core business rules of a company, but a way of structuring the work of its employees, is the Application Layer the appropriate location for this scenario (arrow 5). External systems may use the same logic for deriving user permissions (arrow 4).
