A detailed analysis of desktop and mobile to assess the usuability and funcationality

🚀 KICKOFF

🔎 OBJECTIVES

CarSupermarket.com is a UK-based online car retailer offering a wide selection of used cars. CarSupermarket.com's long-term goal was to improve the usability of the page and generation lead on cars.

  • Understand the pain points of a vehicle detail page

  • Assess the usability and user experience of the page

  • Prioritise recommendations so client can address users’ deepest pain points

Methodology

  • Heuristic Evaluation

  • Competitive Analysis

  • Accessibility

  • Recommendations


📋 Heuristic Evaluation

I started off with the They had already designed out all their screens and had a working prototype in Figma. Our class started with a Heuristic Evaluation so we could hand off some things to work on while the rest of the project progressed.

💡 UX tip: A heuristic evaluation is a great way to grab low-hanging fruit and identify predictable usability issues. You can use Nielsen’s 10 Heuristics for Interface Design to assess user interface (UI) interactions, but don’t let that limit you. These are considered “rules of thumb” because they can be seen again and again in UI designs. If a particular finding doesn’t fit into a category that doesn’t mean it won’t be an issue — it will just require more research on your part to back it up.

I evaluated both desktop and mobile versions of the page, focusing on:

  1. The process that every potential customer will go through to purchase a car

  2. The interaction between customer and receiving help for their purchase.

I went through the page and took notes so I could tag notes by the possible 10 heuristics violated and mark the level of severity.

Heuristic evaluation findings

The most heuristic violations were:

  • Visibility of system status (1 issue)

  • Aesthetic and minimalist design (1 issue)

  • User control and freedom (1 issue)

  • Help users recognise, diagnose and recover from errors (1 issue)


1. Keep users informed


CS should update their navigation.

CS should have very clear indicators around their navigation, otherwise users may stay confused and abandon the site.

  • I recommend CS update their navigation to indicate where a user is located on the site.

  • Why? Humans like to be in the know. Predictable actions and providing confirmation can help build trust between the user and the site.

  • Heuristic referenced: Visibility of system status

2. Give users control


CS should provide users the option to quickly fix mistakes or make changes later.


CS should allow users to change their mind when filling out contact forms and at any time of a user’s interaction.

  • I also recommend CS allow users to create an account to save the cars into a wishlist.

  • Why? Humans make mistakes or change their minds. When an app doesn’t allow changes, users can feel trapped and dissatisfied.

  • Heuristic referenced: User control and freedom

3. Aesthetic and minimalist


CS should make text, especially call to actions legible for the customers.


CS should follow industry conventions and legibility, a number of their call to actions are far too small to read. I recommend updating the font sizing to make it easier.


  • Why? Humans prefer not to work. When a site doesn’t follow what users expect, it can be hard to learn or a barrier to use.

  • Heuristic referenced: Aesthetic and minimalist

🏅 Competitive Analysis

I looked at competitors such as Motorpoint, Arnold Clark and AutoTrader; and compared them to Carsupermarket.com.

Competitive analysis findings

The competitive analysis showed Carsupermarket had a unique proposition but a very similar idea to other competitors, with great success. Research on the desirability of the site and assessing product-market fit should be major priorities.


1. Reserve


CS provides the ability to reserve a car immediately.


Both direct and indirect competitors had a similar approach.

2. Finance calculator


Ability to check finance options for a specific car, allowing the customer to determine whether it's suitable before reserving.

Increasing user interaction and peace of mind for the customer, also seen across most competitors.

3. Presence


CS is well established but not a big name in the car retail industry. How can this be improved?

Very reliable and well established; I propose increase in marketing.


⚠ Accessibility

💥 Recommendations


Overall project findings

CS was a fairly usable site.

Some novel issues may come up with features such as account creation and accessing help.

1. Conduct further research on the desirability of CS

Direct further research on desirability over usability - a perfectly usable site does no good if users don’t want to use it

  • Focus on pain points of users to assess product-market fit

  • Explore further revenue stream

2. Design for the effects of anonymity

Allow users to create meaning and uniqueness in their search for a car to encourage an emotional connection and ability to create wishlist.

3. Follow industry standards

Provide confirmation screens for user actions to reduce confusion

  • Avoid information overload by reducing content displayed to users

  • Refer to conventional patterns of feature placement to enhance learnability

4. Include a comprehensive onboarding experience

Comprehensive onboarding should clarify issues users had with anonymity and privacy

  • Highlight differentiators to increase user engagement and desirability.
