Project Overview

Shein is a global B2C fast fashion e-commerce company. In order to generate more profits for SHEIN by improving the existing site, an in-person moderated usability test session of the Shein website (www.shein.com) was conducted with the primary target users—Gen Z customers—at the University of Toronto in Canada.

Test Script

2. Recruiting

Informal Recruiting

Informal recruiting from UofT email, social media

Recruiting Size

12 participants
3 floaters

Screener

Screeners fit the appropriate target profile for the qualitative research (including age, gender, behaviors,  purchasing habits, etc.)

Recruiting Requirements
  • 60% participants should be female
  • All participants born between 1997 and 2012
  • Half should be price-sensitive participants with low income
  • Half should be trendy-sensitive participants
All participants must:
  • Have access to a laptop or desktop computer with internet access for the session
  • Fluently and confidently understanding and speaking English
  • Not work for Shein or similar e-commerce platform
  • Have online shopping experience

3. Test Execution

Role
  • 1 facilitator
  • 1 observer
  • 1 analyst
  • 1 notetaker
Methodologies
  • Think Aloud Protocol
  • Observation
  • Interview
  • In-context Questions
Reassurance

  • Neutral about the designs
Ethical Considerations
  • The session would be recorded
  • The data will be secured appropriately

  • The participant may withdraw their results at any time –in which case the data must be destroyed.
Tasks
  • Find a specific pink t-shirt with a printed butterfly pattern and letters
  • Identify the right size for a pair of pink jeans based on specific body measurement data
  • Proceed to checkout with the lowest price of the items in the shopping bag

4. Analysis

Affinity Diagram

We created an affinity diagram to organize a large number of findings into their natural relationships. We used both top-down and bottom-up approaches to ensure that we uncovered issues by objectives.

Severity Ranking

According to the issue's frequency, persistence, and the impact the issues may have on the user's efficiency and ability to complete the task, a severity rating was assigned to each problem in the following:

Minor Issue

Users may find challenging to overcome and affects general usability or the user’s overall impression of the website. Fixing such an issue should be given low priority for the next release.

Moderate Issue

Usually won’t stop the user from finishing the task but will have to undertake some of their moderate effort in getting around. The issue is essential to fix, and it should be given high priority.

Critical Issue

Seriously impairs the use of the product. Users are unable or unwilling to finish their tasks. The issue must be fixed before the next release.

Findings

Global Strength
  • The search bar can be accessed on multiple pages and is easy to use.
    Page-level Strength
    • Effective size chart & customer reviews on Product Detail Page
    Global Issues
    Information Overload

    Too much information and abuse of flash create a cognitive overload for participants, discourage usability and distract attention from the site's core value.

    Ineffective Navigation

    The labels are overwhelming and inconsistent in granularity, confusing when users find information.
    The navigation bar cannot be fixed in position while scrolling, making users go back and forth while browsing products.

    Lack of Error Prevention

    There wasn’t a warning message when participants imputed a card number with more digits. The same issue happens in entering a zip code without typing space in between.

    Ineffective Visual Hierarchy

    The lack of a visual hierarchy in the navigation bar and breadcrumbs made it difficult to find the information.

    Page-Level Issues
    "Dark" Shipping Guarantee Fee
    Place Order Page

    The shipping guarantee fee is default checked and is small in visuals. It cannot be deselected once participants leave the page and return.

    Complicated Filter
    Product List Page

    Most labels are too long and at varying levels of granularity, causing participants to struggle with finding a product.

    Unexpected Coupon Code Entry
    Place Order Page

    The Place Order Page is not where participants expect to enter their coupons.

    Unexpected Billing Info Entry
    Pay Page

    The Pay Page is not where participants expect to enter billing information.

    Overwhelming Size Guides
    Product Detail Page

    There are too many size guides, including product measurements, body measurements, model dimensions, and customer evaluations, resulting in excessive time spent on finding a size.

    Unintuitive Shipping Information
    Shopping Bag Page

    The unclear use of free shipping and free express shipping confused participants.

    5. Reporting

    Finally, we shared the usability tests’ findings with relevant stakeholders across our team, to earn buy-in to proceed with our suggested improvements.

    Lesson Learned

    A list of pre-prepared questions will help significantly when it comes time to sit down and run your usability testing sessions. But while a list is essential, sometimes it can also pay to ‘follow your nose’ and steer the conversation in a (potentially) more fruitful direction.

    Ask users to articulate their thoughts as they proceed. Even if they make the “right” selections, it can be very instructive to hear why they made that decision, as well as how they respond and feel throughout the process.

    Keep a poker face. Make sure your responses to questions or reactions are neutral. You’re not looking to hint, influence, or otherwise direct the user. You’re looking to get honest feedback.
