What are that Nielsen's 10 “heuristics” and how to use them?
Originally published on Software Development Hub blog by Oleksandr Kozynskyi, Ux/Ui Designer. Jakob Nielsen's 10 general principles for interaction design. They are called "heuristics" because they are broad rules of thumb and not specific usability guidelines. They are used by usability experts when evaluating and analyzing interfaces, websites or mobile applications. In the process of creating or testing interfaces, their correlation with certain principles and best-known practices is carried out. The method of expert evaluation is very popular, as well as relatively inexpensive and fast compared to comprehensive usability testing.
1. Visibility of system status The design should always keep users informed about what is going on, through appropriate feedback within a reasonable amount of time. When users know the current system status, they learn the outcome of their prior interactions and determine the next steps. Predictable interactions create trust in the product as well as the brand. Tips
Communicate clearly to users what the system’s state is — no action with consequences to users should be taken without informing them. Present feedback to the user as quickly as possible (ideally, immediately). Build trust through open and continuous communication.
