Exercises

Develop an activity diagram based on the followingnarrative. Note any ambiguities or questions that you have asyou develop the model. If you need to make assumptions,also note them. “The purpose of the open Access InsuranceSystem is to provide automotive insurance to car owners.Initially, prospective customers fill out an insuranceapplication, which provides information about the customerand his or her vehicles. This information is sent to an agent,who sends it to various insurance companies to get quotesfor insurance. When the responses return, the agent thendetermines the best policy for the type and level of coveragedesired and gives the customer a copy of the insurancepolicy proposal and quote.”
