Narrative:
We were given descent to 15000 ft but did not begin descent until 1 min later (maybe longer). ATC (ZNY) prompted us and descent was then made to 15000 ft at a good rate of descent. The mode control panel change and altimeter setting took place but neither VNAV nor flight level change was selected until prompted. Conversation during clearance contributed to the task of descending from not having taken place. Fatigue also a factor, but mostly lack of adherence to procedure. Readback to ZNY with altimeter setting given. Selection of flight level change to initiate the descent, however, was not made as the conversation we had been in prior to the clearance continued. I think the cause of this was that the task at hand, ie, altitude change and altimeter setting adjustment, was made and the task 'seemed' to have been completed. Better adherence to full task resolution needed.

Title: A B757 FLC FORGETS TO START DSCNT INTO PHL AFTER RECEIVING THEIR CLRNC FROM ZNY. CTLR HAS TO GIVE THE CREW A 'WAKE UP' CALL TO START THEIR DSCNT.
Narrative: WE WERE GIVEN DSCNT TO 15000 FT BUT DID NOT BEGIN DSCNT UNTIL 1 MIN LATER (MAYBE LONGER). ATC (ZNY) PROMPTED US AND DSCNT WAS THEN MADE TO 15000 FT AT A GOOD RATE OF DSCNT. THE MODE CTL PANEL CHANGE AND ALTIMETER SETTING TOOK PLACE BUT NEITHER VNAV NOR FLT LEVEL CHANGE WAS SELECTED UNTIL PROMPTED. CONVERSATION DURING CLRNC CONTRIBUTED TO THE TASK OF DSNDING FROM NOT HAVING TAKEN PLACE. FATIGUE ALSO A FACTOR, BUT MOSTLY LACK OF ADHERENCE TO PROC. READBACK TO ZNY WITH ALTIMETER SETTING GIVEN. SELECTION OF FLT LEVEL CHANGE TO INITIATE THE DSCNT, HOWEVER, WAS NOT MADE AS THE CONVERSATION WE HAD BEEN IN PRIOR TO THE CLRNC CONTINUED. I THINK THE CAUSE OF THIS WAS THAT THE TASK AT HAND, IE, ALT CHANGE AND ALTIMETER SETTING ADJUSTMENT, WAS MADE AND THE TASK 'SEEMED' TO HAVE BEEN COMPLETED. BETTER ADHERENCE TO FULL TASK RESOLUTION NEEDED.
