Narrative:

Prior to departure; we had to do an aircraft swap (including a change in aircraft model type) and then they changed our departure gate two times. It was the first officer's leg and he loaded the flight plan into the navigation computer. I checked the route and it all looked good. We were filed for the zaver departure. When the clearance came in it showed us with an andys departure. However; the first officer failed to load the andys departure and I failed to notice that it had not been loaded.we were cleared for takeoff and to fly to the first fix which is hisor. We took off and at 200 ft the first officer asked for autopilot two. We now noticed an aircraft taking off just before us on runway 18C. As we climbed out; tower switched us to departure. I switched to 120.5; which is departure for the zaver SID. Departure called radar contact and switched us immediately to 124.0 and checked in as the aircraft started to turn to the right in the direction of the aircraft departing 18C. I was thinking that the other aircraft better turn soon as we were headed his way.departure told us to turn left to a heading and asked what departure we were on. I told him the zaver and he said we should be on the andys. At this point I looked at the clearance and knew he was right. Now it was too late to change the SID and departure gave us vectors to a fix on the andys SID. I then inserted the rest of the SID by hand.I was wrong and should have caught the first officer's error. I do feel that both sids having the same first fix gives a false sense of security. Tower cleared us to hisor and that was our first fix. Only after you are airborne do you learn something is wrong and it is not easy to take out the other SID and load the fixes as you are still in the initial climb phase of flight and there is still a lot going on.however; I'm the captain and it is my responsibility to ensure everything is done right.

Title: Distracted by pre-departure duties; an air carrier flight crew failed to note the revised departure in their PDC clearance. A brief track deviation after takeoff ensued.

It was the First Officer's leg and he loaded the flight plan into the navigation computer. I checked the route and it all looked good. We were filed for the ZAVER Departure. When the clearance came in it showed us with an ANDYS Departure. However; the First Officer failed to load the ANDYS Departure and I failed to notice that it had not been loaded.We were cleared for takeoff and to fly to the first fix which is HISOR.
