The importance of excxuting

An artist who doesn't know how to paint isn't an artist at all. Great UX designer are masters of their tools and craft, and should be able to provide qualified solutions to your users’ problems to improve user experience. On their resumes, designers will list the software and technologies they know, such as:

• Photoshop, Sketch, Illustrator
• HTML5, CSS3, JavaScript
• Other cool things

And while knowing software and coding languages is crucial in creating the deliverables you'll need for your team, a great UI designer will be able to execute their ideas with justification and validation.

This goes back to communication. A great designer clearly communicates the needs of the users. Then they apply their findings to the designs they create while talking with users to gather feedback — it’s a continuous loop of communication as designs are executed.
While ux design is a comprehensive project,only if you execute resolutely you can make a perfect work!
