Create a Context DFD model

The following user narrative was heard from by Edna London, who is the production shop floor supervisor for Super-Flow in Eden Prairie.  

"The purpose of the production scheduling system is to respond to a production order that is typically submitted by our sales department.  

You see, this system has to generate a daily production schedule and raw materials requisitions.  Raw materials requisitions are going to be created for the materials management department - you know, they are eventually going to use these in their purchasing management system to figure out what they need to order and from whom they need to order.  

Of course, the daily production schedule is generated for me from the system.  The system also generates job tickets each day - these tickets tell the production workers exactly what work is going to be done on each machine during the following day's production run.  

You know, if we don't get these job tickets done in advance each day, you have no idea just how fouled up the machine allocation process can get.  "

Your assignment for this problem is to convert this narrative into a context DFD for Edna's production scheduling system.  

Part A: Draw the context DFD model

Part B:  State any assumptions you made when creating this diagram & state any questions that you may have to ask Edna in follow-up meetings.
