“How many people should be “in charge” of a digital sign?”
There should be one person in charge of content for the sign, although they may have another person that helps create content for them. Multiple people updating content is asking for trouble … when the boss doesn’t like the content, who is in charge? There should also be one person ultimately responsible for maintaining needed hardware or software updates and trouble-shooting issues. Again, that person may have others that help, but that answer to the head tech. It is difficult when the boss wants to have final authority, but wants someone else to do the actual weekly or daily updates.
