Appliance Warehouse - Module 5 - Week 6 Email 1 - Diagrams 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. P.S. Mae named our new system "SIM", short for "Service Information Management" Email 3 - Appliance Service Plan Changes 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 where 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. Email 4 - Decision Tree Now you'll need to simplify the decision table so that you can create a decision tree
