Again, the requirement includes "The organization shall retain appropriate documented information as evidence of the results." So, even if he sees in real-time what is going, the documentation will be needed.
I'm sure he wants to 1) deliver products on-time, 2) with good quality (low returns/complaints). At a minimum, those are things to be measured and recorded. Those recorded entries can be later evaluated, e.g., avg on-time per month or per quarter, etc. against some target or threshold. It need not be extravagant or convoluted, but I imagine that he has in his mind already some set of parameters he uses to mentally measure how well his business processes are working, so it's just a matter of finding low-effort ways to record that data and perform occasional review/evaluation of that data.
