Please help with the diagrams. These were the instructions and information I was given.

Case Assignment: Data and Process Modeling Before You Begin - Assignment Specific Based on prior requirements gathering, you are now ready to create logical models for the new system. This phase is essential to understand the data and decision processes in the new system. During this stage, you will create data flow diagrams (DFDs), decision tables, and decision trees.

-In this simulation environment, you will review the emails which contain instructions for this case assignment. -Utilize Lucid Charts to create the diagram and tree

Complete the following for submission: 1. Create a DFD-Context Diagram identifying all the processes and the entities with at least 1 inflow and 1 outflow into each entity. 2. Create a Decision Table 3. Create a Simplified Table 4. Create a Decision Tree

Hi G, Hopefully, you are not too bogged down with the DFD. The owner and store manager met this morning and came up with some new rules that will need to be implemented in the SIM system: - The owner and store manager have decided to offer customers a service plan were they pay a flat rate once a year. With this plan, customers only pay for the cost of parts when they have their appliance(s) serviced. They can only buy a service plan if they have purchased an appliance from Appliance Warehouse. - With this new service plan, if they have service on their appliance more than 3 times during the year, they will have to pay the full amount of the service fee and cost of parts. - If the customer does not buy a service plan but buys their appliance from us, we will give a 20% discount off the service fee for the life of their appliance. - Everyone else will pay the full cost of the service plan and parts cost. Create a decision table from these rules. I would like to see your first pass at this by our next scheduled meeting. 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'Il 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.

Hi G, 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. Appliance Warehouse Webmail Client Resource Library Template Library Company Website ?

Now you'll need to simplify the decision table so that you can create a decision tree. The programmers find it very helpful to have all the decisions laid out in a decision tree. Please have these done by the end of the week. Carlie
