Putting together a presentation on UI/UX…suggestions needed [closed]

I’m a technical recruiter looking to learn more about UI/UX so that I can better attract quality candidates, and I’m putting together a presentation for a potential client. They are testing my knowledge of the 2-3 core discplines of UX and how they benefit organizations. I’ve narrowed my list to:

  • Interaction Design
  • Visual Design
  • Information Architecture

Basically how I’m looking at it (and remember I’m a recruiter not a designer) is that visual/interactive design are the front end and IA is the back end to a site. The site needs to look good, make sense and have usability, and then have the necessary content to back it up.

Does it seem to you that I am on the right track?
