Narrative:

I was training a developmental (on east/north departure, combined on this confign). Traffic quickly went from light to moderate to heavy. In my allowing the developmental to manage the session, the traffic situation became increasingly complex. Aircraft X departed runway 22L on a 120 degree heading. Aircraft Y departed runway 14L on a 100 degree heading. The aircraft X course was going to transgress a sector boundary and I gave him a heading to avoid that airspace (070 degrees). The intention was to climb him later after he was in a position to do so. (He could not be climbed at the same time due to arrival traffic.) due to volume, complexity and coordination, I was unable to initiate a climb or turn in a timely manner and separation was lost about 15 mi east of ord.

Title: TRAINING SESSION AT ORD GOES FROM LIGHT TFC TO HVY COMPLEX TFC AND RESULTS IN A LOSS OF SEPARATION.

Narrative: I WAS TRAINING A DEVELOPMENTAL (ON E/N DEP, COMBINED ON THIS CONFIGN). TFC QUICKLY WENT FROM LIGHT TO MODERATE TO HVY. IN MY ALLOWING THE DEVELOPMENTAL TO MANAGE THE SESSION, THE TFC SIT BECAME INCREASINGLY COMPLEX. ACFT X DEPARTED RWY 22L ON A 120 DEG HDG. ACFT Y DEPARTED RWY 14L ON A 100 DEG HDG. THE ACFT X COURSE WAS GOING TO TRANSGRESS A SECTOR BOUNDARY AND I GAVE HIM A HDG TO AVOID THAT AIRSPACE (070 DEGS). THE INTENTION WAS TO CLB HIM LATER AFTER HE WAS IN A POS TO DO SO. (HE COULD NOT BE CLBED AT THE SAME TIME DUE TO ARR TFC.) DUE TO VOLUME, COMPLEXITY AND COORD, I WAS UNABLE TO INITIATE A CLB OR TURN IN A TIMELY MANNER AND SEPARATION WAS LOST ABOUT 15 MI E OF ORD.
