UX architect has a different role than a designer or analyst.
He may or may not be directly involved in designing a user experience but is responsible for a meaningful presentation of information and organizational structure on the website from the users’ perspective.
While it sounds easier, achieving this requires a lot of effort to be put in by the architect. The architect also has to don an analyst’s hat to ensure that all the user requirements are met while presenting the information.
The usability of the website is greatly affected by the quality of work put in by the architect and if you are not able to complete a task that you thought was simply on a website, the UX architects have to be blamed. It is a matter of fact that a UX architect must be well versed with the principles of designing so that he may comprehend the design elements so that the website is usable in every sense.
