Narrative:
Aircraft #1 (DH8H/right) was on a westerly heading at 16000 ft. Aircraft #2 (F2TH/right) was climbing to 15000 ft out of psf on a heading of 280 degrees radar vectors. Aircraft #2 was then cleared direct sax VOR which would turn him left away from aircraft #1 and climbed to 17000 ft. Aircraft #2 didn't start his left turn for another 1 min 14 seconds. As the controller; I should have waited until aircraft #2 had turned before climbing him through the altitude of aircraft #1. Also; the pilot should have started his turn when instructed to do so. As a controller; I expect immediate compliance with my instructions. If a pilot is unable to turn upon being instructed; he/she should immediately inform me as the controller.
Original NASA ASRS Text
Title: ZBW CTLR EXPERIENCED OPERROR AT 16000 FT WHEN ACFT WAS LATE IN RESPONDING TO ATC CLRNC.
Narrative: ACFT #1 (DH8H/R) WAS ON A WESTERLY HDG AT 16000 FT. ACFT #2 (F2TH/R) WAS CLBING TO 15000 FT OUT OF PSF ON A HDG OF 280 DEGS RADAR VECTORS. ACFT #2 WAS THEN CLRED DIRECT SAX VOR WHICH WOULD TURN HIM L AWAY FROM ACFT #1 AND CLBED TO 17000 FT. ACFT #2 DIDN'T START HIS L TURN FOR ANOTHER 1 MIN 14 SECONDS. AS THE CTLR; I SHOULD HAVE WAITED UNTIL ACFT #2 HAD TURNED BEFORE CLBING HIM THROUGH THE ALT OF ACFT #1. ALSO; THE PLT SHOULD HAVE STARTED HIS TURN WHEN INSTRUCTED TO DO SO. AS A CTLR; I EXPECT IMMEDIATE COMPLIANCE WITH MY INSTRUCTIONS. IF A PLT IS UNABLE TO TURN UPON BEING INSTRUCTED; HE/SHE SHOULD IMMEDIATELY INFORM ME AS THE CTLR.
