User Persona 👤
Dell is an American technology company that develops, sells, repairs, and supports computers and related products and services, and is owned by its parent company of Dell Technologies.
My goal is to test the Dell website's usability for students who are interested in purchase Dell laptops. And propose solutions that meet users' needs according to the heuristic evaluation and usability testing results.
The target market for Dell is students, employees, and small businessmen who need a new laptop with lots of features but don't have a lot of budget.
As for this case study, I chose college students as target users. Dell’s laptops are cost-effective for college students who need to complete a wide range of activities, from taking notes in class and completing assignments to streaming movies late at night in the dorm.

Finding the right product
Understanding the content
Check out process
Navigating site
From the survey, I learned that a lot of people are having a hard time finding the laptop they like. For people who are not tech savvy, I needed to strategize the content so that users can understand the specs quickly. Later, when I rearranged filter categories, I utilized the data we collected from the question, "Rank the specific factors you find important if you were to purchase a laptop" to execute the design.
Heuristic Evaluation 📝
Next, I conducted a heuristic evaluation on Dell's website. I have noticed four main user centered design principles that were being violated, as they either continued to reoccur in various forms and created one or more significant usability troubles.
These four problems are flagged as the main issues I plan to validate in usability tests later and the starting point from which I will also approach the redesign phase.
View the detailed heuristic evaluation here.
1
Lack of Consistency & Standards:Website’s navigation is inconsistent and incomprehensible, which would cause users to have difficulty finding the products they want.
3
Lack of Aesthetic Integrity: The style of the whole website is not aesthetically pleasing and negatively impact user experience
2
Lack of Linguistic Clarity: Website’s content are long and the information is in the same layout. There’s no distinction and hierarchy between different information.
4
Lack of Visibility of System Status and Responsiveness: Users do not know which step they are on during the check-out process, and they don’t know what filters they have selected.
Usability Testing 🔬
In order to test Dell website usability through a typical user journey of laptop purchasing, I recruited 12 participants who matched student customer persona. 8 of them are female, and 4 of them are male. They are either college students or pursuing master's degrees or higher.
The testing started from asking some easy questions about their laptop purchasing behaviors and their impression of Dell. Then I asked participants to complete three tasks (listed down below) to understand the usability issues with purchasing a laptop through Dell website. Lastly, I asked them questions about their overall experience after using the Dell website and some branding questions to better help us to understand how could I redesign and brand Dell differently to attract its potential costumers.
My usability script was designed to uncover qualitative and quantitive data to back up presumptions found in heuristic evaluation. Some metric I used to conduct the usability testings include task time, number of failed attempts, task satisfaction, and completion rate.
Whether the users were able to discover the task assigned which is to find a portable computer meeting their needs
Whether the users were able to recognize and use the comparison tool
Whether the users were able to modify the selected laptop and check it out without any hindrance
Task 1
Discoverability
Task 2
Use Comparison Tool
Task 3
Modifying Checkout Process
"Why is the website making me think so much, why can't they offer a straightforward solution"
"I would not recommend this website to other people unless I hate them."
"The website is pretty ugly, and fonts are small."
"Would prefer font text to be sized a bit lar ger and the color is not pleasing to them as they would have hoped. "
Key Quotes from Participants
Task #1 Testing Results
The Average time to find the laptop they interested was 3 minute
Minute
Participant
All of the users were able to discover a touch-screen laptop; however, the time and assistance varied from user to user. The average time to discover the right laptop was 3 minutes.
So... What has caused them to slow down the process?🤔
On average, they questioned, "What should we do?" and "Where should we go?" 3 times each. This means that they were unable to locate the option for touch-screen laptops in the filter section, which caused the process to take longer.
Unlike Task #1, for Task #2, out of the total 12 participants, only 5 of them can successfully use the comparison tool.

Solutions 🪄
Through my solution I wish to enhance the Discoverability, Legibility, Consistency of Dell Website.
Filter Issues
"Where is the touchscreen option?"
"Wow, the filter is so long."
"I'll have to use control F to search ‘Touchscreen’."
Change category name from “Factor” to “Features”
Change “2-in-1” to “Touch Screen”, which is easier for customer to understand
8/12 participants have a hard time finding the "touchscreen" option. (Some of them end up using Control+F to search the keyword"touch".)
No prioritization:Order of the filter does not meet users' expectation
Prioritize filter and combine similar categories (progressive disclosure)
Default to minimize all the categories (Because there’re too many categories
Eliminate unnecessary categories based on our survey results
