Rule n° 91 - Navigating through a complex process does not cause any previously-submitted data to be lost.
It is certainly extremely comfortable for the user to be able to navigate through the various steps of a complex process. Of course, it is essential to warn them when data can be lost. This is the subject of another of the web quality assurance rules. It is even more useful to ensure that all data entered by the user is saved at all times.
Goal
- Simplify input and corrections in forms divided into multiple steps.
- Limit the risk of abandoning the procedure.
Solution technique
At the level of the navigation management in the process steps, record the data entered at each stage, so that it can be displayed again without loss of data after the user has navigated through the steps.
Moyen de contrôle
Use the navigation functions in the steps before data entry, and manually verify that the data entered in each step is retained and displayed again afterwards.
