According to Nielsen Norman Group
“True user experience produce

to use”.

4. Common reasons why people don't
start by UX Design
X You think you can represent the user.
X You focus on building the product right
instead of building the right product.
X You think of user experience as
an afterthought.
@tchenpat

5. Why you should start by UX Design
Focus on users and their needs early
helps you define a product with necessary
features only.
UX design helps define the simplest
and most efficient path to help your
users reach their goals.

10. To end…
“Asking
"What would be best for our customer?"
leads to average results.
Instead ask,
"What will blow our customers' minds?"
” Box CEO Aaron Levie
UX Design is just about blowing your customer’s minds !
So, start with it and keep refine it !
