Each person on a post must be cleared on that post by the Manager. The Manager, by questioning, reaches, with the person, an acceptable, embracive stable datum that exactly defines the job.
The person, with this sorted out and cognited upon, then can withstand organizational confusion in his area.
The Manager does this, no one else. The Manager does not tell the person the definition. The definition must be arrived at by the person in his own words.
Applies to all personnel.
