  environment

Today, were going to get to something that works
(sort of)

11
But first, be sure you have the opening screens
that you designed last time.

12
Today, were going to figure out (design) what
comes next.

13
Your Challenge

• Design a series of screens that show how a user
  would use your ATM to do the things its intended
  to do.
• Keep in mind something Ive said a few times
  only put on the screen objects (including text)
  that will help users to somethingno extra stuff

14
We will do an in-class test of your design for
the following case

• A user wants to see if there is enough money in
  one or more of his or her accounts so that 40
  can be withdrawn.
• If there is, withdraw 40 if not, withdraw as
  much as possible.
• If your design cannot handle this transaction,
  explain to us why not/

  your semester project.
