Simplifying the Post-booking Experience for Sixt Riders





01 Brief

Thank you for visiting!

I'm working to improve the mobile experience.

Please view this project on a larger screen for now.

Sixt, a global mobility provider, was expanding its presence in the U.S. market but faced logistical challenges, particularly a lack of prime rental locations at airports. This created friction for users during the post-booking phase, the phase where they are ready to pick up their car. Our team at Monstarlab was tasked with reimagining and digitalizing the post-booking experience to ensure a seamless journey for riders from pick-up to car return.

02 The Problem

The business needed innovative solutions to bypass logistical limitations, such as the lack of prime rental locations, while growing its market presence.

Users were confused with finalizing their car selection in the 48 hours before pickup, the long wait times during pickups, and unclear drop-off instructions.

03 Discovery

To deeply understand, define and validate the problem, we analyzed each phase of the post-booking journey—from car pick-up to drop-off—by conducting on-site research at New Jersey and New York airports, and through user interviews.

The research phase revealed major pain points like long wait times at pickup, unclear drop-off instructions, and confusion about how to log the car’s condition at pickup, which were frustrating users.

04 Towards the Solution

We focused on improving the key stages of the post-booking journey: car selection, where users select a car category and choose from available fleet options 48 hours before pickup, the pickup process, and the drop-off experience.

Before moving into high-fidelity designs, I developed wireframes and tested multiple options, and refined them based on feedback.

Car Selection

Users were overwhelmed by the car selection process, especially frustrated by the cluttered information in the old UI.

The business also aimed to increase upgrade conversions during selection, so we tested multiple design options to streamline the car profiles.

Finding the Car

Sixt was transitioning to a QR-based system to enhance the pick-up experience. I tested several different layouts to ensure users would find the QR easy and useful.

Drop-off

To also improve the drop-off process, we designed and tested solutions to provide clear instructions and guidance.

05 The Solution & Impact

After iterating on multiple designs, we delivered a comprehensive set of hi-fidelity designs to Sixt’s internal development team. Parts of the design, including the booking confirmation and drop-off features, were implemented by Sixt in 2023

However, due to evolving technology solutions and business priorities, certain features, like the interactive navigation, were saved for future consideration. The Sixt team continues to iterate on our foundational work as they improve their customer experience.

06 Reflections

I’ve had the opportunity to explore various research methods, from field trips to on-site interviews, and aligning business goals with user needs. The iterative nature of the design process, collaboration with product managers, and refining solutions based on real user insights were particularly rewarding.
