Narrative:
During our brief for departing ord; we planned on a 9R departure. With the understanding we could get assigned another runway; we planned on the most likely and closest taxi runway. We figured a two engine taxi out would be less distracting and decided to run the before takeoff checklist before calling for taxi; understanding that if the runway was changed; we would have to run the checklist again after making the runway change. When we called for taxi; we did get a different runway than we planned for. I understood the route to the runway and verbalized that to my first officer (first officer). He asked to go heads down; I asked him to wait till after I had turned onto bravo; and had a long straight taxi. We followed atcs instructions just fine. Made no errors. And got to the runway safely. The problem was that while my first officer was heads down and busy with running the checklist; an aircraft cut in front of us. We were never advised by ATC about this aircraft. It was night and the aircraft was blocked from my view for a time by the window post on the captain's side. We never got close; but might have if I had not seen the airplane and slowed down. It is not uncommon for this to happen in ord.

Title: The flight crew of a large transport reported that the recent implementation of a new before takeoff checklist resulted in greatly reduced situational awareness by the pilot performing the checklist; and increased the potential for taxi conflicts or mishaps.
Narrative: During our brief for departing ORD; we planned on a 9R departure. With the understanding we could get assigned another runway; we planned on the most likely and closest taxi runway. We figured a two engine taxi out would be less distracting and decided to run the before takeoff checklist before calling for taxi; understanding that if the runway was changed; we would have to run the checklist again after making the runway change. When we called for taxi; we did get a different runway than we planned for. I understood the route to the runway and verbalized that to my FO (First Officer). He asked to go heads down; I asked him to wait till after I had turned onto Bravo; and had a long straight taxi. We followed ATCs instructions just fine. Made no errors. And got to the runway safely. The problem was that while my FO was heads down and busy with running the checklist; an aircraft cut in front of us. We were never advised by ATC about this aircraft. It was night and the aircraft was blocked from my view for a time by the window post on the captain's side. We never got close; but might have if I had not seen the airplane and slowed down. It is not uncommon for this to happen in ORD.
