Software usability: how to design effective user interfaces

As a software architect, you cannot improve the performance of humans, but you can improve the performance of human-machine interaction by designing an effective user interface (UI), that is, a UI that ensures fast interaction with humans, which, in turn, means the following:

• The UI must be easy to learn to reduce the time that is needed for the target users to learn how to operate it. This constraint is fundamental if UI changes are frequent and for public websites that need to attract the greatest possible number of users.
• The UI must not cause any kind of slowdown in data insertion; data entry speed must be limited only by the user’s ability to type, not by system delays or additional gestures that could be avoided.
• Today, we must also consider the accessibility aspects of our solutions since doing so allows us to include more users.
