Curbside: Designing a seamless, doorstep booking flow for vehicle services.
After a friend developed a web platform for on-demand car washes, I saw an opportunity to scale the concept into a native mobile utility. Acting as the product designer, I translated the core web experience into a mobile-first app for on-demand vehicle maintenance. This case study details how I streamlined complex scheduling and service customization, allowing drivers to book everything from a quick wash to a roadside tire change directly to their driveway.
Workshop
Auditing the Competition, Finding the White Space
I began with a comprehensive competitive audit of existing car care utilities, analyzing both user flows and App Store reviews to identify structural weaknesses in our competitors' designs.
User Challenges:
- Technical Instability: High checkout drop-offs caused by buggy, multi-step booking forms.
- Operational Friction: Unreliable contractor arrival times and zero live tracking.
- Interface Distraction: Intrusive ad banners and cluttered visual hierarchies.
- The Opportunity for Curbside: Users overwhelmingly praised "hassle-free, rapid booking." This became our North Star.
Competitor Research: A snapshot of current market offerings and pain points.
User Interviews & Core Themes
I conducted six in-depth user interviews with active drivers to understand the psychological and logistical barriers to routine vehicle maintenance. Here's what I found:
Theme A: The Trust Gap (Quality & Pricing Anxiety)
"I want a clean car, but I don't want to go somewhere that's going to scratch my paint. It has to be reliable and reasonably priced."
"I like my car clean but it's hard to find a good spot. It has to be reasonably priced and reliable. I don't want to go somewhere that's going to mess up my car"
"They're expensive and quite out of the way typically."
The Solution: Curbside must feature transparent pricing upfront, clear detail package breakdowns, and provider ratings to establish immediate credibility.
Theme B: The Convenience Conflict (Time Poverty)
"My schedule is packed, and traditional washes are expensive and out of the way. If I have to wait, I need a place with WiFi so I can stay productive."
"My schedule is really packed and it's difficult to find time outside to go in and out of a car wash all the time"
"It's hard to find time to get my car washed."
The Solution: By bringing the service directly to the user's driveway, we eliminate travel and wait times entirely, returning valuable hours back to their day.
Aligning Strategy & Defining the Goal
Persona Development: Developing Empathy Maps and User Journey Maps to better understand the user journey.
The Problem
Busy vehicle owners face massive friction, inconsistent service quality, and scheduling anxiety when using traditional car washes. They lack a highly reliable, frictionless way to schedule vehicle care into their tight calendars.
Information Architecture, Paper Concepts, Ideation
Rapid Ideation: Using paper sketches to iterate on screens before moving to high-fidelity wireframes.
User Flow & Low-Fidelity Wireframes: Establishing the core navigation paths and layout structure to ensure a seamless checkout experience.
Prototyping, Testing, Results
High-Fidelity Iteration (Version 5): Refining the UI based on usability testing feedback to polish the final visual design and interactive elements.
Reflections & Learnings
- Mentorship accelerates growth: Seeking out continuous feedback from UX mentors was the most rewarding part of this project. Their guidance completely changed how I think about my role, helping me connect my design work to real-world industry standards.
- Digging deeper during user research: While my initial user interviews gave me a solid baseline, I noticed gaps where I could have uncovered even richer insights. Going forward, I'm focusing on refining my research style to ask more open-ended, clarifying questions rather than sticking strictly to a set questionnaire.
- Respecting the status quo: It is incredibly easy to fall into the trap of designing for novelty. During this sprint, I had to actively pull myself back from "cool" features to focus on what actually mattered: keeping the checkout flow simple and frictionless. Innovation only works when it supports usability.
