However on the right the error has been passed through from the backend system with no filtering or translation. In this example, the same error has occurred in both instances. Color is also important as it can help indicate the severity of an error or warning. Leaning on technical language, or database error terms will not be beneficial to the user. It is important to provide a clear and understandable reason for an error (where possible), and give instructions so that the error can be remedied. Language, tone and design is important in these communications. When the inevitable errors happen, it’s important to communicate to the user. Instead, the system should recognize that the action is not possible, and hide it from the selection. If all options are available, and an operator clicks “Unload” they’re going to get frustrated when the system tells them this failed. If an operator tries to dispatch an unload command on a vehicle, for that to work, the vehicle must have a load. Consider once again an industrial system that relies on particular parameters for certain actions. A great example of this is with selecting actions from a dropdown menu. One common way of promoting errorless use is to hide actions and options that are invalid. Delaying, or not showing a response to the action leaves a user questioning. As a user when you click save, you want to be able to know whether your action was recognized.

Take for instance the action of saving a document. This means that applications that don’t provide timely feedback as to what the system is doing may create a more negative or confusing experience. Demonstrate current stateĪs one of the heuristics developed by Jakob Nielsen, visibility of system status states that users should be informed about what is happening inside a product or website, in a reasonable response time following the action. In this article we’ll explore some good ux design examples, as well as some examples of bad ux, and how principles like the Nielsen Norman Heuristics are represented in the real world. Understanding those principles is one element, seeing how they reveal themselves in practice is another element of understanding good versus bad experiences. Thankfully there are a number of guiding principles that can give us direction in understanding what makes for a good user experience. Understanding the makeup of good and bad user experience can be subjective and hard to pinpoint.
