A very important thing to do with any of these devices is to really learn all that they are able to do and how to use them effectively. I have found that more than half of the people using them don’t know very much about what they are capable of doing/monitoring.
If you are operating a big facility, you might want to have a couple people on your staff become the “tech” people for wearables. I give staff with extra responsibilities bonuses or slightly higher wages. Depending on the situation.
