Nicely said Well of course we are sharing background and tips in our course with my colleagues as well. We want to transfer as much useful knowledge as possible but we must count that only some minor piece of all will be remembered.
Even we have almost 100 specialist only couple of them we have fully focused on Check Point. Rest of them covers other platforms or need to do just simple things across more platforms.
In result you can't expect that 8 months after course they will be able to remember all background which you gave them. They uses written presentations or documentation of course. Even that they open TAC on shift in case of Major incidents it is expected that you'll act before you'll get engineer on-line. So that is the reason why we want to make their life easier.
Thanks to this community we can improve it for sure. Topic likes Common Check Point Commands (ccc) and other wonderful scripts helps us a lot.
In conclusion for the future it is not a bad idea just "forget" to present zdebug and remove it from materials.
