The Intention Of This Criterion
How can you reduce the risk of data entry errors?
Sometimes it is impossible to completely protect yourself from data entry errors. But you must be sharpo Reduce risk by using better data entry methods. Manual data entry is resource intensive and monotonous. So it hurts your teams and takes time to use that data.
The purpose of this Success Criteria is to help you avoid the catastrophic consequences that are the main result of making a mistake when you perform an amazing action that cannot be undone. For example, buying non-refundable airline tickets or filing a new order to buy shares in a brokerage firm’s financial account are serious consequences. If the user made a mistake in the date of the trip, he may not receive a ticket for that day, which is difficult to exchange. The user incorrectly specifies the number of shares to buy for or buys more shares than expected. Both types of errors involve transactions that occur immediately and cannot be changed later, which can be very costly. Similarly, the unlikely and unrecoverable situation can arise when users inadvertently change or delete data stored in a database that they need to access later, such as massive loss of documents when deleting a file or documentation. Heis not intended to request confirmation for ordering everyone to register, but only to or create changes to personal files, registrations or other data.
Users with disabilities are more likely to make mistakes. People with reading disabilities may confuse numbers and letters, and people with reading disabilities may accidentally press the correct keys. The ability to undo user actions allows you to correct serious errors that can have disastrous consequences. Allowing the ability to summarize the correct and generalize information gives the user the advantage of detecting an error before taking real action with serious consequences.
The user can control what data can be viewed by the user and what data the user can intentionally modify and/or delete with an action. Examples of how the user typically controls this data could be updating the phone number address for the user’s account, or deleting the current record of past accounts from the site. It doesn’t apply to things like this.Like browsing web logs and tracking search engine data that the user cannot see or directly influence.
Specific Benefit Of Success Criterion 3.3.4:
-
Providing fatal error protections helps all users who experience problems become more likely to make errors.
Examples Of Success Criteria 3.3.4
-
confirmation of an order.
