Usability Heuristics: 10 Usability Heuristics for Design

Usability heuristics are guidelines for ensuring that user interface design is comprehensive, straightforward, and user-friendly. They serve as rules of thumb when building new programs, mobile apps, or websites that prioritize the user experience. These general principles lead to user-error prevention and encourage clear, minimalist designs so that even novice users can understand how digital products function. Companies that follow usability heuristics ensure the visual design is intuitive so new and experienced users can easily navigate the products and services.

Usability consultants Rolf Molich and Jakob Nielsen first developed the most commonly-used set of heuristics in 1990 to understand usability problems and establish design guidelines that favor clean and efficient user controls. This usability inspection method identifies the efficiency of use of the user experience in human-computer interactions:

1. 1. Employ real-world conventions. Designers should make icons and images recognizable to users. For example, if your app is for booking hotels, images of twin vs. full vs. queen vs. king-sized beds should be made clear via the graphics. Comparing the system operations with real-world objects is helpful to the user.
2. 2. Include emergency exits. User freedom is critical, and if users make a mistake midway through an action or purchase, they should have a clear out or the ability to redo a step. Including emergency exits can help build user confidence.
3. 3. Set clear rules for users. Ensure there are no structural inconsistencies in user tasks. Decide on the rules and standards of your website or program and stick to them to minimize cognitive load and the user’s need to learn new information. To ensure that designs are user-friendly, companies can usability testing, an evaluation process that involves real users performing tasks monitored on the site or app.
4. 4. Create clean designs. A minimalist interaction design ensures that only the pertinent content and icons are on a given page. Too much clutter can confound the user.
5. 5. Include error recovery. Error recovery is an essential part of user testing. Ensure that error pop-ups diagnose mistakes, so there is clarity for the users on the path toward completion.
6. 6. Build-in error prevention. Good error messages help steer users in the right direction, but designers should still work error prevention into the structure of digital products to avoid user mistakes in the first place.
7. 7. Be transparent with system status. Visibility of system status is beneficial to users. Be transparent about software updates, changes to the interface, and improvements or upgrades in progress.
8. 8. Create recognizable information. Information should be made clear on each page or profile so that users do not need to recall information from previous pages. Key content that spells out how to use each feature or complete each step should be preexisting on each page.
9. 9. Make accessible help buttons. Usability should be clear enough in your software that users do not need help. Still, user help should be accessible via a search bar or menu navigation. Feedback and a place for submitting questions should also be accessible.
10. 10. Incorporate shortcuts. Keyboard shortcuts are unnecessary, but more expert users can use them as accelerators. Shortcuts allow for customization and enhance the user experience.
