Narrative:

In descent from altitude, passing 10000 ft, did not slow to 250 KTS. When cleared to descend from 14000 ft to 8000 ft, descent was started in vertical speed mode. Airspeed was set at 250 KTS and descent was set at 2500 FPM. Speed was 300 KTS. Approach gave a change of runway to runway 9L and the new runway was entered into the FMC. A new approach briefing was conducted. While all this was occurring, the aircraft descended below 10000 ft, and at approximately 9200 ft it was noted that airspeed was 283 KTS. The speed brakes were deployed. Descent continued and airspeed was slowed to 250 KTS by 8900 ft. PF let administrative duties interfere with his flying of aircraft. Situational awareness was momentarily low.
