Identify suitable actors, use cases and relationship, and draw the use-case diagram for the following scenario. Write use case specifications for any one use-case. Consider how an insurance companys system handles claims. When a claim is submitted by a customer through e-mail, the system stores the customers claim information and automatically sends a reply mail notifying the same. A claim specialist logs onto the system and checks for new claims from customers. He views customers claim history if needed. He then decides reimbursements and updates the claim information to mark the claim as processed. The system maintains the information about the specialist handling a particular claim. At the end of the day the system administrator logs in. he is given the option to view all information stored in the system. He may then ask the system to generate mails to all customers whose claims have been processed. The customers can log into the system and dispute reimbursement amount. The claim specialist can view these disputes and update claim status if need be. A corresponding mail, mentioning if reimbursement has been updated/remains same, is also generated, and sent to the customer. Note that, a claim specialist is a person who investigates details of claims and decides the reimbursement based on customers claims history.
