RESEARCH

Key findings & Pain points

Key usability insights and systemic issues uncovered through research, guiding strategic design improvements.

Fragmented Booking Flow

Users were required to jump between pages and re-enter information multiple times, creating unnecessary friction in the booking process.

Lack of Mobile Optimization

The existing website did not adapt well to mobile devices, leading to poor usability and high abandonment on smaller screens.

Underutilized Business Verticals

Services like van rental and chauffeur were difficult to discover, resulting in missed opportunities for conversion and differentiation.

Service Design & IA Strategy

We analyzed the unique needs of each business vertical including car rental, car leasing, van rental, and chauffeur services. Each offering had distinct users, expectations, and operational constraints. By defining separate user flows and IA models, we ensured that content and navigation were fully aligned with user intent. This led to the creation of dedicated microsites that delivered focused, conversion-oriented experiences.

User Types & Booking Contexts

We identified unique user behaviors tied to each business stream — from daily rental users to long-term leasing clients. Rental users prioritized quick comparisons and seamless mobile experiences, while leasing customers demanded detailed information, flexible configurations, and service reliability. These patterns shaped key journey priorities and segmentation logic.

Content Personalization Strategy

Each microsite was tailored with dedicated content hierarchies and UI modules, reflecting the business model and decision-making path of its target user. The rental flow emphasized offers, vehicle availability, and booking speed, while the leasing flow prioritized configurability, credibility, and service terms. This modular approach ensured relevance without compromising brand cohesion.

EXPLORATION

Wireframing & Layout Testing

Following the completion of the IA and service design, I focused on rapidly producing mid-fidelity wireframes to validate assumptions and map booking flows across different user types. This phase prioritized fast iteration cycles and early feedback, helping reduce misalignment before visual design began.
