Draw a use-case diagram and a set of activity diagrams for the following system. GoodStuff-of-the-month-club (GoodStuff) is an innovative new company that sells memberships to people who have an interest in certain products. People pay membership fees for one year and each month receive a product by mail. For example, Stuff has a coffee-of-the-month club that sends members one pound of special roast coffee each month. Stuff currently has 6 memberships: Coffee, Healthy Snacks, Deserts, Flowers and Computer Games, each of which costs a different amount. Customers usually belong to just one but some belong two or more. When people join GoodStuff, the telephone operator records the name, mailing address, phone number, e-mail address, credit-card information for their monthly payments, start date and type of membership service(s) (example: coffee). Some customers request a double or triple membership that comes to the same address (example: 2 pounds of coffee, triple healthy snacks, etc). The computer game membership operates a bit differently from the others. In this case, the member must also select the type of game (action, arcade, fantasy/science, fiction, educational, etc) and age level. GoodStuff is planning to greatly expand the number of memberships it offers and will name the programs to indicate what monthly plans they are using (example: movies will be MovieStuff, toys - ToyStuff, shoes ShoesStuff, cheese CheeseStuff, organic fruit - FruitStuff and organic vegetables - VeggieStuff), so the system needs to accommodate this future expansion. Stuff is also planning to offer three month and six month memberships. Use Visio for this. (20 points)
