Aim for uniformity – design elements should be easily recognisable, even if it’s the first time a user has been to your website. Make interfaces intuitive. For example, don’t paint the home button red when most sites have it green.

Ensure the same usability – for example, the interface elements – menus and lists – should work the same way on every page in the application and on the website.

Provide informative feedback – a modern interface responds immediately to user actions. The system should clearly display the current status on the screen: whether a payment is forthcoming, whether a manager has taken a request to work, whether a report has been delivered.

Work on closed problem-solving flows – users must clearly understand when they started a process and when they finished it. This principle works well in combination with visual statuses.

Eliminate errors – the ideal interface consists of tunnels through which users can immediately reach the goal. Aim for a place where users cannot even make mistakes on the way to the goal. Even simple actions and statuses can sometimes help a lot.

Make it easy to undo – no matter how well thought out the interface, all users are human, they worry and make mistakes for different reasons. Prepare reports carefully if something does not go according to plan. Or simply provide a guaranteed cancellation option. This approach will help you save attention, money, time and customer loyalty.

Let users feel in control – a good interface is like a spoon in your hand. You always know what to expect. Users understand that the interface is a machine and therefore expect full control.

Reduce the load on short-term memory – create the feeling that “everything is at hand”. Then users won’t feel they’ve lost something and have no reason to worry that valuable information or work results need to be stored or remembered somewhere.
