I don't think I would do justice to your question if I tried to provide an answer to that, not being an IT expert and not having looked at that issue recently. It would be very difficult for me to determine whether investments in IT are appropriate or not insufficient without being an expert or having looked at that issue.
I know these systems are of critical importance from my years working at the CRA, where the assistant commissioner there did wonders to keep the systems together, but beyond offering that anecdotal comment, I cannot provide a reasonable or plentiful answer. I'm sorry about that.
