I am the Head of the functional department . When I have detected a number of personnel requirements , I report the vacancy to the Personnel Department . Then I wait to get the job description for review before it is advertized . Under certain circumstances , I must ask for corrections again , otherwise I approve the job description . Sometimes it also happens that the colleague from the HR department still has questions about the tasks and requirements before he can describe the job . Then I am available for clarifications , of course .
