Nowadays companies seems to be more enthusiastic to make designs better. Having a good system core and expert developer team is not enough and customers need their experiences be seen by companies. Here comes UX (user experience) designer to help improving material designs and access. By getting tests and finding out the best place and pace for elements in the pages and forms, UI designers job start. They make UX designs real! It’s like adding soul to dead body!
But why they’re these much important?
Why UI & UX is necessary for every system? and obviously why there’s framework?
Let me first clarify “framework”. Framework is called to elements which are designed in special concept that designers, no matter UI or UX, use theme to be coordinate with each other. e.g. bootstrap for flat design.
About the questions:
Firstly I should say, if you find a system or program from 10 years before you could hardly find some systematic option that can change directions or language; but today it’s important that a system or software support multi-lingual ability.
When your finds out that he or she is able to change system color, OR it was important for your company to open some page or form in less than 3 clicks, they feel satisfied and also you’ll have a grate feedback from theme. They’ll tell their friends about your system, their friends tell their friends, and these process will become a cost-free ad for you!
If you don’t have UI and UX designer, no one would believe you are professional…
