Batch ordering

Your manager overhears you discussing batching with a colleague and asks you to stop by for a quick chat. She has recently read a proposal from sales for a given process to read, parse, and store some order data on a regular interval until complete. She's not sure the order described makes sense and would like you to help place the tasks in the correct sequence.

The tasks in question involve reading groups of no more than 10 files in a given round and there are expected to be 15-18 files on any given instance.
