"Modart" is an art gallery that earns its revenue as an intermediary between

artists and customers. Artists set the price of their artwork displayed in the

gallery. When a customer purchases a piece, Modart receives 20% of the amount

paid. Among other systems, Modart has a "Request system," that manages the

requests from artists to display their artwork in the gallery.

Artists communicate to Modart's manager, by phone of by email, a list of

proposed artwork to display, including the number and characteristics of the

artworks. The manager checks within the Artist System whether the artist is

affiliated with the gallery--only affiliated artists are allowed to display their artwork at Modart.

After the manager verifies that the artist is affiliated with Modart, the manager

selects which of the proposed artworks will be displayed. The manager sends the

approved list to the artist, who then should confirm his or her agreement with the updated list.

After receiving the agreement from the artist, the manager inputs the information

on the approved list into the Scheduling system and sends an email confirmation to the artist.
