Questions To Ask Access Control Manufacturers

This Spring/Summer, we are going to tour or visit several access control manufacturing companies. I'd like to get your feedback on general questions to ask during our tour. Of course, we cannot ask business or technology sensitive information (ie: how do people hack your systems?) but we certainly can ask for general details on manufacturing processes/ R&D methods/ sales - management structure.

Our reports will provide a general overview of each company, but what questions are you especially interested in us asking?
