Usability Testing, Validation, and Evaluation for Beauty App

---

Company: Macao Lisa International       Role: Sole Researcher          Timeline: 2 months 

In November 2021, Lisa International company was about to launch the beauty shopping App in a few month.

The research that I conducted for this project was focused on: 

- Validation: Validate the usability of the shopping App

- Use over time: How do participants reacts to the beauty shopping App over a period of time

- Heuristic evaluation 

- Usability test 

- Diary study 

- Satisfaction Surveys 

During the iterative design process, we conducted multiple usability testing. Here were what we learned. 

- Search function: Some users do not know how to use the search function, so we used light grey text as a hint.

- Waterfall design on the front page: Multiple users complained that the waterfall design was too lengthy and exhausting. We switched to a modern, minimalist design that doesn't overwhelm users.

- Purchase button: Make it more prominent by using a black color and increasing its size. 

- Search by categories: Add features like search by brand names and functions. 

- Brand identity: Use a black and white color theme to convey the luxurious image of the brand.  

- User satisfaction increased by about 20% within two months of the launch

- Sales increased from $210,000 to $1,150,000 quarterly after launch.
