Hi,
Just reading through the thread, have your depot guys done a demographic of the damaged packages.Do you get a % more damage from customers in one part of the country to another when you look at size of orders to those areas.
Being Sherlock here, your problem could be one of the handling depots in the delivery company or road route or airline or rail company.
Or even a Monday work blues.Tom...
all these would be answered by the idea the OP offered in his first post. create a data logger with sensors, even GPS, and send in the same box.
I had a thought that it could be lousy customers that claim damaged goods.
or this guy
you will never know until you datalog.
