I can probably make light of them... ;-)
I did a v4 Implementation Path course many years ago - a the time that was the full (BO sanctioned) training scheme and was largely not worth the paper it was printed on - from a development perspective.
Resonably solid grounding in basic user report building techniques, if you have a simple Data Mart with a logical design... and you don't want to build complicated reports.
The Designer & Supervisor training was a bit of a joke. The examples used on the course were far too simplified and didn't really hold up against real world examples.
That said, I understand BO have now extended the courses and cover things in more depth... anyone been on one more recently?
