Different options of determining reporting hierarchy in PS

What are the different options of determining reporting hierarchy in PS as delivered?

To determine the reporting hierarchy for an employee in PS the delivered options are as follows:

i) If the organization is position driven and uses full position management then the reporting is based on reports to field.

ii) If the organization is not position driven then the reporting can be driven based on supervisor id defined in job as one option.

iii) If the organization is not position driven then the reporting hierarchy can be driven based on the department tree structure as well. Example: In job if the employee is in department X then the line manager will be the manager of that Department X. If the employee happens to be the manager of that department as well, then the line manager will be the manager of the parent department to X in the department tree structure.
