ROI of UX: Mozilla Support Site Redesign

Nielsen Norman Group recently shared a great case study showing return on investment of utilizing user-centered design and usability testing for a website redesign. Take-aways are:

  • Mozilla support website redesign took 560 hours (or 14 weeks)
  • Multiple UX research methods uncovered pain points and areas for improvement
  • Designs were tested as prototypes and improved based on user feedback; 7 versions were assessed during project lifecycle
  • As a result, there was a 70% decrease in support questions submitted, and
  • 80-90% of submitted questions were answered within 24 hrs, an increase from 40-60% rate before re-design
