Project Summary:

We were tasked to perform a heuristic evaluation of a website of our choosing and come up with two key processes that we will be redesigning and user testing for the rest of the semester. My partner and I split the workload by tackling one key process and I spearheaded the redesign and user testing for the key process of adding/removing items from Zara's shopping page.

Problem

Problem

Zara's shopping page makes it difficult for users to efficiently add or remove items from their cart, leading to frustration and confusion. This matters because poor usability in such critical interactions can drive users away, reduce customer satisfaction, and negatively impact sales.

Value Proposition

Value Proposition

Our ultimate solution to the problem is user-centered and not business-centered in which the implemented changes were to boost the efficiency of the users of the platform with less consideration for the design decisions made from Zara's business standpoint.

In particular, the solution to my key process is to enable users to declutter information about the product and efficiently add and remove items from the shopping cart by employing drop-down menus for item information and offering easier access to the features with immediate feedback and pop-ups in the redesign.

Research & Discovery

User Research:

A heuristic evaluation was conducted on the Zara website and user opinions were collected through surveys and in-person/online interviews

User Research:

A heuristic evaluation was conducted on the Zara website and user opinions were collected through surveys and in-person/online interviews

Key Findings & Pain Points:

Two key processes were examined during the Heuristic Evaluation:

  • Searching for a product from the search page

  • Adding an item to the shopping bag

Overall usability is satisfactory, but the improvements for these two key processes can boost efficiency by increasing readability and reducing task completion time.

Design Rationale:

  • Design follows a similar layout to not confuse returning and frequent customers

  • Substituted the information box with drop-down menus to minimize clutter on item page and bring focus on the item’s image

  • Clearer typography and icons to discern clickable buttons and descriptive text

User Testing

User Testing

Usability Testing Process:

  • We employed qualitative and quantitative evaluation methods, and task-based methodology for the usability testing.

  • Before the test, we sent out participant screeners asking the test participants about their previous online shopping experience to learn more about their preferences.

  • Next, the tests are moderated and conducted in a remote environment.

A total of 8 tests were conducted collectively.

Reflection & Takeaways

Reflection & Takeaways

  • Online customers may have a habit that is formed by shopping through other platforms, therefore the other platforms’ interface design also needs to be considered during the research phase.

  • Learning how to conduct heuristic evaluations and employ the theories from Nielson’s 10 usability heuristics and Norman’s principles of Interaction Design within the research phase of the project. 

  • The redesign is conducted through customers as the target audience rather than Zara’s stakeholders as the target audience, therefore the design is tailored towards promoting customers’ user experience with the addition of the quick delete button.

The key takeaway I learned from this project would be that designing user experience can differ depending on whether the objective is to optimize customer’s UX (providing a quick delete button) or to optimize business sale’s UX (not providing a quick delete button).

Biggest Challenges & The Solution

Biggest Challenges & The Solution

  • Biggest Challenge: finding participants for usability testing who have experience using the Zara platform. 

  • Solution: we overcame this by asking participants who had a general online shopping experience.
