- One-click Process: Because the system advances on any click, the user doesn’t have a chance to verify that they selected the correct option, reducing the safety.
- Large Buttons: The buttons are all large, so the likelihood of accidentally clicking the wrong button will be smaller. Users will also see the button depress when clicked, so they will get that feedback about which element has been selected. These together improve the safety.
- Forward/Back Buttons: If the user makes a mistake, she can chose the back button to correct it. Error correction improves safety. The forward buttons let her navigate back to her current position without reentering information – which would increase the likelihood of making another error.
- Status Bar: The user can keep track of how far she is. This allows tracking of how far in the process she is, and in case If a ballot got was missed or double-submitted, this mechanism will help her catch that error. For example, if the user sees that she is entering the 3rd ballot, but the ballot number is 2, she knows that one of the ballots was not properly submitted.
- No confirmation: Aside from the button depressing at the user's click and the ballot number incrementing, the user gets no feedback. Hence, if she makes a mistake it will be hard to spot and realize this.
