I hope it's more robust than that.

But for all I know, it could be manual. Perhaps Bob runs a COBOL script each morning to pull a list of recipients, which Sally double checks for the various quirks that this old legacy system can produce, before giving it to Jim to run the payment script - with specific parameters for known edge cases - and if there is an error then Jenny from IT knows what to do. Only problem is that Bob, Sally, Jim and Jenny just got fired, the department was ordered to delete their documentation, and the responsibility now lies with some 19 year old with no background in either Finance or COBOL who just showed up on his first day thinking "how hard can it be?"
