Usability Testing — CostcoGrocery Website


This project was done as part of Dr. Anthony Andre's ISE 215 User Research and Usability Testing course. As a team of 4, we conducted user research to evaluate the usability of Costco's website, with a focus on the homepage and the CostcoGrocery sections.

Project Duration

Feb 2021 - May 2021

Key Takeaways

We found that many Costco shoppers prefer to shop in-person rather than online, even though one of Costco's recent goals has been expanding and growing their e-commerce platform. Through a series of usability tests conducted through Zoom, our team observed the following pain points from the participants, which negatively affected their online shopping experience:

  • cluttered and disorganized information architecture

  • inconsistency between items displayed in results

  • difficulty determining the price of certain items

  • tediousness when requesting live chat support

Heuristic Evaluation — Cinemark Mobile Application


This project was done as part of Dr. Anthony Andre's PSYC 273 Seminar in Human Factors course. I methodically examined the Cinemark mobile application against established design heuristics to evaluate the user experience.

Project Duration

Oct 2021 - Dec 2021

Key Takeaways

The interface violated four major usability principles:

  • Consistency and Standards

  • Error Prevention

  • Match between System and the Real World

  • Aesthetic and Minimalist Design

Due to these violations, the user may have a more difficult time completing the tasks that the application was made for due to deviance from established design patterns. This deviation makes it hard for users to understand and navigate the Cinemark application because they need to spend time searching or trying to understand the interface before proceeding.

Analysis of the interface showed a total of 31 usability issues divided into three categories of priority: low (7 issues), medium (15 issues), and high (9 items). Many of the usability issues can be addressed by implementing minor visual design changes to align the interface with user expectations.
