The email request from Carlie Davis that initiated the ssignment is directly below in a blue font for clarity. Notes from the JAD session are also provided below for convenience. You should have completed reading Chp 5 before starting this project. DFD - Context Diagram - all the information to build this DFD is given in the Chapter 5 emails. You need to identify the process and the entities and should have at least 1 inflow and 2 outflow into each entity. Diagrams Email from Carlie Davis Thanks for the great information gathered through your interviews and questionnaires! Hopefully, you are at the point that you can envision how this new system will function. You should create a Data Flow Diagram (DFD). This diagram will help the programmers understand how information is flowing through the proposed system. I suggest that you use the notes from the JAD session. They have identified the entities and processes and you can use this information to create a context diagram. Please have this done by our next meeting. Carlie P.S. Mae named our new system "SIM", short for "Service Information Management", and everyone loves the name. Let's call this new system "SIM" for now on. DFD - Context Diagram - all the information to complete the following DFD is given in the Chapter 5 emails. Students need to identify the process and the entities and should have at least 1 inflow and 1 outflow into each entity using the the Notes from the JAD Meeting as shown below. 1. Add at least one more outflow arrow/descriptor from the SIM box to the Customer box and 2 more inflows from Customer to SIM. 2. Add at least one more outflow arrow/descriptor from the SIM box to the Technician box and 1 more inflow from Technician to SIM. 3. Add at least one more outflow arrow/descriptor from the SIM box to the Parts Dept box and 1 more inflow from Parts Dept to SIM. 4. Add at least one more inflow arrow/descriptor from the Appt. Setter box to SIM. Have fun! Alan Marks (store mgr): I am so excited to be launching this new service to our customers! It's going to be great to not have to refer out customers to unknown service companies. Besides, if they can't fix their own appliance, we might be able to convince them to visit the store to replace it. Emily Johns (service manager): Yes, I agree! We need to work very closely with the parts department in order to get the service estimates out to the customer and get the parts for the repair quickly. Meredith Parks (programmer): I think it would be a good idea to name our new service system. Any ideas? Alan Marks (store mgr): Service Information System? SIS? Emily Johns (service manager): Service Information Manager? SIM? Meredith Parks (programmer): OK, let's vote. Meredith conducts a quick vote and all are agreed on SIM. Maddox Farley (parts director): I'm a little worried about how this SIM will affect my inventory levels. Meredith Parks (programmer): I need you to break this down a bit for me. Who is involved in this new process? Emily Johns (service manager): We definitely have the customers, parts department, parts, technicians, appointment setters, and calendar. Meredith Parks (programmer): OK, now we have our entities. What are the processes that will take place? Alan Marks (store mgr): Well, we will need to generate estimates and final invoices. Emily Johns (service manager): Right. And we'll make appointments, order parts, assign technicians to appointments. Meredith Parks (programmer): Anything else? Emily Johns (service manager): A calendar should be able to be viewed or printed for each technician. Each technician needs their daily schedule of appointments at the beginning of each day. Alan Marks (store mgr): I don't think so. Payment will be accepted by the current cashier's system. Meredith Parks (programmer): OK. DFD below there are two Inflow / Outflow examples provided per entity. Your assignment is as follows
