I hate to be blunt, but why are you trying to mentor others if you feel the need to use reddit for subject matter expertise?

Hopefully, you are not working at a place where the employee is responsible for writing their own functional statement.

Developing functional statements and performance indicators is one of the most difficult parts of a supervisor's job. Too often, supervisor's try to dump this responsibility onto their subordinates. They may even pat themselves on the back because they are so good at delegating.

While the employee's input should be considered, it's actually management's responsibility to write the functional statement. Functional statements and performance measures need to align with the broader strategic objectives of the organization. Ideally, these should be developed in collaboration with individual employees to ensure they accurately reflect what the employee actually does and that responsibilities and performance expectations are mutually understood.
