F3wmb,
It did work and successfully identified a few areas where the trg system had some obvious gaps quite quickly.
The main problem with the system was that it was never properly manned, as it really needed someone light blue to run it, probably as 50% of a full time job. Iirc the duty was given to a civil servant typist or equiv to run after I left, which meant that there was no one to kick the results up the chain when there were discrepancies in output and input standards, and therefore I suspect that the whole system was forgotten about in the PTC relocation.
I certainly haven't seen evidence of it's existence in about 6 or 7 years I don't think, though the results of the initial year of operation did come to fruition about 5 years after we id'd some easy changes in courses.
