88. Predictable Errors

Commission Errors

• Lets say you're trying to get a task done, such as turning on the Wi-Fi on your tablet. All you have to do is touch the On/Off control on the screen, but you think that you also need to touch the drop down-menu and select the network. That's an example of a commission error:
• YOU TOOK ADDITIONAL STEPS THAT WERE UNNECESSARY.

Omission Errors

• Now lets say that you're setting up e-mail on your new tablet. Your e-mail address and password. What you don't realize is that you have to set up your outgoing and incoming mail settings; you've only set up the outgoing ones. In this case you omitted steps.

Wrong-action errors

• Let's go back to setting up email. You enter your email and address but you enter the wrong server name for your email outgoing server. That is an example of wrong action error.
• You took an action at the appropriate point in the procedure, but it was the wrong action.
