Pareto the data and go after the big hitters first, this will give you the greatest return on the investment. Initially i would focus these efforts right away, not wait 3 months to discuss. Non-conformancs equal lost revenue.
The sooner the issue is addressed the more likely to solve the problem, as time lapses people don't recall what happened, or they become complacent. Since you mentioned someone else is handling the day-to-day activities they should probably be the lead for these improvements, and you should be setting the priorities for them based on your analysis of the data.
If you try to do everything yourself you will become overloaded and burned-out.
