The overall numbers for your store are very strong. You are exceeding your overall goals. However There are a couple of departments where there are some performance issues. What would you be most and least likely to do

I would first check the staff to see if they are doing there job or maybe they do not have enough employees.

You can also compare the departments to see what works and what doesn't

Maybe equipment is broken or missing and is holding them back.

It can also be social problems, maybe they are not happy or do not get along. are they on a strike? those are more rare situations but can happen.
