QUESTION $3$

Create a set of use cases for the following system: Of$-$the$-$Month Club $($OTMC$)$ is an innovgye young firm that sells memberships to people

who have an interest in certain products. People pay membership fees for $1$ year and each month receive a product by mail. For example,

OTMC has a coffee$-$of$-$the$-$month club that sends members one pound of special coffee each month. OTMC currently has six memberships

$($coffee$,$ wine, beer, cigars, flowers, and computer games$),$ each of which costs a different amount. Customers usually belong to just one,

but some belong to two or more. When people join OTMC, the

telephone operator records the name, mailing address, phone number, e$-$mail address, credit card informgon, start date, and membership

service$($s$)($e$.$g$.,$ coffee$).$ Some customers request a double or triple membership $($e$.$g$.,2$ pounds of coffee, three cases of beer$).$ The

computer game membership operates a bit differently from the others. In this case, the member must also select the type of game $($acon$,$

arcade, fantasy$/$science ficcon, educgongl, etc.$)$ and age level. OTMC is planning to greatly expand the number of memberships it offers

$($e$.$g$.,$ video games, movies, toys, cheese, fruit, vegetables$),$ so the system needs to accommodate this future expansion. OTMC is also

planning to offer $3-$month and $6-$month memberships.
