Successfully completed client presentation and design proposal.

  • Delivered prototypes from pre- and post- user testing.
  • Presentation was received well, and planned integration of the about page and later additions for other pages.


Our team presented the redesign in a presentation style to show case our research, process, and insights. The clients liked the presentation, after the review.

The clients decided to integrate the about page first as it strengthen their credibility and humanize the company.


Since our client was based in the UK, it was hard to get feedback and initial insight to how their dealers and selling process looked like. Since we were in charge of the user facing side, I was not aware how the envisioned integrating the dealers page as well as I would have liked.
