Is there a possibility of identifying those conflicts earlier, so that parties could be notified sooner in the process? I know it was an issue they raised, and you might take that under consideration.
Another area that was raised was the fact that when people were getting ready for trials, for one reason or another it couldn't go ahead because something was lacking and it fell apart. I know that in the legal process, at least in the judicial system, they have pretrial management conferences at which all of the parties are called together before the actual hearing to resolve any difficulties that there might be. They streamline the process and condense the actual hearing many times to much fewer days.
Is there anything like a pre-hearing management process that could try to eliminate many of the difficulties that the parties might face if you otherwise hadn't had it?
