system analysis and design

Q1 (14 points = 5 marks): ABC Credit Corporation typically took five business days to process each financing deal. The process is described as follows: First, a customer calls a salesperson with a proposed deal. Six employees sitting around a conference table process the call. The employee who receives the phone call logs it and writes the details on paper. An assistant then carries the paper to a second employee, who initiates the next phase in the process by entering the data into an information system and checks the client's creditworthiness. This employee then writes the details on a paper and carries the paper, along with the original documentation, to a loan officer. In phase 3, the loan officer modifies with the customer's standard ABC loan agreement. This involves a separate information system from the one used in phase 2. Details of the modified loan agreement, along with the other documentation, are then sent on to the next station in the process, where a different assistant employee determines the appropriate interest rate for the loan. Phase 4 involves its own information system. In phase 5, the interest rate from phase 4 and all the paper generated up to this point are then used to create the quote letter. The quotation is then sent back to the salesperson via overnight mail. Draw a DFD for processing a financial deal by ABC
