If we don't have witnesses, we could discuss work plans, just to make the meeting completely relevant. If we hear from witnesses without really knowing why and go fishing, the meeting may lose its relevance and effectiveness.
In my humble opinion, if you agree, we would be better off not hearing from these witnesses before we receive the documents. We could discuss the work plans, especially since we have not been able to meet over the past week, even though we have been running around after each other for various reasons.
What do you think?
