Uncontrollable costs can be a concern when a manager is being judged based on departmental expenses. For example, there is a scheduled increase in the rent payment to the landlord, and a portion of this expense is allocated to a department that occupies a portion of the rented property. The manager of that department appears to be managing his expenses poorly because of the rent expense increase, even though he was not responsible for the rent agreement.
