Easy Onboarding - Easy Process
To streamline the complex process of long-term car subscriptions while effectively explaining the differences between traditional rentals and subscriptions to users. The solution lies in creating clear and concise messaging that highlights the unique benefits of subscriptions, such as flexibility and cost savings, compared to traditional rentals.
Additionally, simplifying the subscription signup process through intuitive interfaces and transparent communication will help minimize friction and make the experience seamless for users.
By refining the search parameters to specifically highlight subscription offerings, users can effortlessly explore and select from a curated list of available subscription vehicles, enhancing their overall browsing experience and expediting the process of finding the ideal car subscription.
User Flow: Car Subscription Feature
In implementing the car subscription feature for users, we've established a clear and intuitive flow to facilitate their journey. Users begin by learning about the car subscription service and its benefits before browsing through a dedicated search page designed specifically for car subscription vehicles. Once they've found their desired subscription, they seamlessly proceed through the booking process, complete payment and deposit transactions, and finally receive confirmation of their subscription booking.
Back-Office Management: Car Subscription
On the back-office side for location owners, we've implemented distinct separations to effectively manage both rental and subscription services. Owners can define the vehicles eligible for the subscription program and select the appropriate booking type (rental or subscription) when creating a booking. Additionally, our calendar interface distinguishes between rental and subscription bookings, allowing owners to efficiently track and manage reservations for both types of services.
Car Subscription Separation on the Backoffice of Locations:
Define Subscription Program Cars: Location owners define vehicles eligible for the subscription program.
Select Booking Type: Location owners choose the booking type (rental or subscription) when creating a booking.
Different Rental Types: The calendar interface distinguishes between rental and subscription bookings, ensuring clarity and effective management of both types of reservations.

Oscar Car Subscription upholds stringent standards in delivering exceptional user experiences, prioritizing clarity, and ease of use. This ethos underscores a meticulous approach, emphasizing accountability, attention to detail, and comprehensive documentation.

Bringing It All To Life
The gallery below shows some of the designs
location backoffice
At the outset of our soft launch, we introduced Oscar's car subscription feature across web and mobile platforms. The rollout proceeded smoothly, marking a significant milestone in our journey. Despite the complexities involved in introducing a new service model and the inherent challenges of an MVP launch, the process unfolded seamlessly. This successful debut underscores our team's dedication and meticulous planning, highlighting our commitment to delivering innovative solutions to our users.
Soft-start with MVP
THE LAUNCH
We ran an A/B/C test to find the best call-to-action (CTA) button text for a booking platform, with three options:
1. "Book now",
2. "Choose vehicle",
3. "Continue".
Test Scope
The test ran for one month across two markets, Denmark (DK) and the Netherlands (NL).
Success was measured by:
-Conversion rate – the percentage of users who completed a booking.
-Proceed-to-checkout rate – the percentage of users who clicked the button and moved to the next step (/step2).
-The primary goal was to improve the proceed-to-checkout rate, anticipating that it could reduce customer service inquiries by providing more information within the platform.
Results and Conclusion:
Using Google Optimize, we found that the "Continue" option had the best proceed-to-checkout rate. This led us to conclude that renaming the button to "Continue" was the most effective choice, guiding more users through the booking process while potentially reducing customer service workload.
A/B Testing for Button Text on Booking Form
THE EVOLUTION
Context:
Oscar proposed hiding the vehicle year from the frontend to increase the conversion rate. A similar approach had shown promising results previously. The goal was to test this idea more broadly in the Spanish (ES) market while retaining all car information, except for the year.
Test Parameters:
Markets: Spain (ES)
Split: 50/50
Duration: 4-8 weeks, with a check-in after 2 weeks
Changes: Hide vehicle year from all frontend displays, including car boxes, car information, and filters. Measure customer service (CS) complaints to gauge any negative impact.
Results:
The experiment ran from March 10, 2023, to April 28, 2023, in the ES market. Key outcomes were:
- Conversion rate: 0.74% with the year hidden and 0.68% with the year shown
- Probability: A 79% chance that hiding the year is the optimal configuration
- Modelled improvement: Between -20% and +66%
There was no day during the experiment where showing the year had a better conversion rate than hiding it. Although the increase wasn't dramatic, it was consistently better when the year was hidden.
In a meeting on April 28, 2023, the team agreed to hide the vehicle year across all markets based on these results.
A/B Test for Hiding Vehicle Year
These changes had a significantly positive impact on the user experience. By categorizing the booking form inputs and removing unnecessary steps, we made the process more intuitive and efficient for users. Users now find it easier to navigate through the booking process and input their information, resulting in a smoother and more satisfying experience overall.
“We decided not to overwhelm users."
From this project, I learned the importance of adapting to user needs and preferences to enhance the overall user experience. It's crucial to simplify complex processes, streamline navigation, and prioritize transparency to ensure user satisfaction and engagement. Additionally, I gained valuable insights into the significance of iterative design and continuous improvement, as well as the effectiveness of leveraging user feedback to drive product enhancements and optimizations.
