1) Please create a process map for withdrawing cash from an ATM machine as described below:
Janet needed some cash and walks up to an ATM machine. She inserts her debit card. The machine returns the card and the monitor reads: "could not read the card try again". Janet recognizes that she has entered the card in the wrong direction. She takes the card and turns it around and insert the card again. The machine keeps the card and the monitor reads: "enter pass code". Janet enters a 4 digit code. The monitor reads: " error, try again".
Janet enters the code again. The monitor displays: Withdrawal? Yes No
Janet selects Yes. Displays shows:
