When a claim related to a major car accident is evaluated, a clerk first retrieves the corresponding car accident report in the Police Reports database. If the report is retrieved, it is attached to the claim file. The claim file and the police report serve as input to a claims handler who calculates an initial claim estimate. Then, an $“$action plan$”$ is created based on a $“$checklist$”.$ Based on the action plan and the initial claims estimate, a claims manager negotiates a settlement with the customer. After this negotiation, the claims manager makes a final decision, updates the claim file to record this decision, and sends a letter to the claimant to inform him$/$her of the decision.
