          They’ve already designed the interface


           Head-Ex has been thinking about expanding their business for a
           while and they already have a design for the interface to the new
           delivery system. This is what it needs to look like:




                                                Depot:                           There are a bunch
                                                                                  of data-entry

                                            Description:                          fields.



                                              Address:












                                                                                        This is where the
             There is a                          Save                                    delivery details
              single button.                                                            need to be saved.




           So how will it work? It’s pretty simple, actually. The user enters the
           details for a new delivery, including the description of the contents,
           the address it’s heading to, and the name of the Head-Ex depot it   deliveries.txt
           will be dispatched from. When the user clicks the Save button, the
           details are saved into a file called deliveries.txt.







                          What’s the difference between this GUI and the ones you created before?
