Question 3 and 4 please

Carson, who is a member of the human resources department at the Elrod Manufacturing Company plant is constantly being asked by employees how much is taken out of their paychecks for insurance, taxes, medical, mandatory retirement, and voluntary retirement. It takes up to a few hours every day, says Carson.

He would like a Web system that would allow employees to use a secure logon to view the information. Carson wants the system to interface with health and dental insurance companies to obtain the amount remaining in the employees account for the year. He would also like to obtain retirement amounts saved along with investment results. Carson has a high regard for privacy and wants the system to have employees register and give permission to obtain financial amounts from the dental insurance and retirement companies.

1. Draw a use case diagram representing the activities (employee registration and employee benefits balances) of the employee benefit system.
2. Write up a use case scenario for each activity for the use case diagram you constructed for Elrod Manufacturing in part a. (Utilize the following Use Case Scenario template)

   2. Write a brief tutorial or create a short Microsoft PowerPoint presentation for Carson on how to draw context level diagrams. Be sure to define any technical terms, as well as the reasons for drawing a context level diagram early in your visits to Elrod Manufacturing.
