If aspects of the manufacturing done at your factory change each shift, and every day and shift requires some particular information applicable that day, you could use NetMailBot to send manufacturing instructions to your plant floor staff so they know how to proceed.
Perhaps each shift works on a different area of an overall manufacturing project, and you need to synchronize a shift's planned production with whatever was achieved by the previous shift. Or, maybe your shop provides contract manufacturing services - such as a machine shop making parts to customers' specifications or a printed circuit board fabrication plant - and each shift is handling some new orders or parts of orders. You could send the applicable information for each order (specific sets of manufacturing instructions, CNC machine programming instructions, or PCB layout files, to name a few) to each shift's crew. Again, this could be done automatically using shift staffing information contained in a database.
