What is Functionality in UX/UI Design?

Functionality refers to whether a design works and helps the users meet their goals and needs.

From products such as chairs or tables to designs such as books or web interfaces, functionality varies but is everywhere.

When a design is highly functional, it does what it’s expected to do and does it well. Good design has a purpose and is crafted in such a way that it will consistently and reliable execute a particular function.

UX designers know the importance of creating functional products, so they run a lot of usability tests to ensure everything is working properly and as expected.
