Narrative:

On approach the flap position indicator indicated a slight split. The pilot flying did not notice any roll. The QRH was referenced and the approach continued to landing. Maintenance was notified and a logbook write up was made. Dispatch was notified through maintenance. After reviewing the events; a better decision would have been to discontinue the approach in order to fully analyze the situation and fully apply the QRH. When there is a jumpseater in the cockpit; I normally brief that they are part of the crew and to speak up if they see something. The jumpseater did do this; and it was very helpful; but there were times when I found the timing distracting and interrupted my train of thought. On approach; the time was compressed as the approach duties interrupted the QRH duties. If the approach had been discontinued there would have had time to fully discuss the situation and utilized all available resources. A plan could have been better communicated with more time and the checklists completed. This time would have been available if we had discontinued the approach. Upon landing we talked to maintenance and made a logbook entry. Dispatch was notified through maintenance; but I should have contacted them directly.
