Best Practice 3.6 – Provide error suggestion (Baseline level)


When a user makes an input error, always provide the user with a suggestion to fix the error if ever possible.

 

Before Rectification
A sample mobile application page with a generic error message displayed at the top of the input form.
The example above shows an error message that is not helpful enough because it does not provide an adequate description of what needs to be corrected.
After Rectification
A sample mobile application page with a detailed error message displayed at the top of the input form.
In contrast, this example shows a message that provides a good explanation of what needs to be corrected.
