Design Sprint → MVP Build

From dispatcher calls to roadside rescue at a tap

Star Leasing's StarCare Breakdown Service handled everything by phone—long hold times, no visibility, no data. We transformed SBS from a cost center into a digital profit center with a cross-platform mobile app and REST API.

Overview

A national truck leasing company goes digital

Star Leasing is a national leader in the rental, lease, sales, and maintenance of semi-trailers. Their StarCare Breakdown Service (SBS) provides 24/7 roadside assistance to drivers—but the entire process ran on phone calls. Drivers waited in call queues, dispatchers had no real-time visibility, and there was no digital foundation for growth.

This initiative was driven by Star Leasing's relationship with its largest client, Amazon, and the need to provide a best-in-class digital experience for drivers on the road. Star Leasing engaged Digital Scientists for a three-phase engagement: a GV Design Sprint to validate the concept, an MVP Blueprint to plan the build, and a full product development phase to ship a cross-platform mobile app with a REST API—all in under seven months.

The vision extended beyond roadside service: Star Leasing saw an opportunity to lay the foundation for a multi-generational product plan (MGPP) connecting IoT devices in trailers for predictive maintenance and driver training.

The Challenge

Roadside breakdowns ran on phone calls and paper

Over-the-road trailer breakdowns are problematic for truck drivers and can lead to missed delivery windows and significant revenue loss. Star Leasing needed to modernize its entire breakdown service workflow.

Phone-Dependent Dispatching

Drivers waited in call queues to report breakdowns. "Phone is the least efficient form of communication."

No Real-Time Visibility

No ETA tracking for technicians. Drivers had no idea when help would arrive.

Cost Center Burden

SBS operated as a pure cost center with no path to generate revenue or added value.

No Digital Foundation

No app, no IoT integration, no predictive maintenance—everything was manual.

Jobs To Be Done

What drivers needed to accomplish

Submit service requests without having to call a dispatcher

Create an open line of direct communication between driver & Star Leasing team

Specify trailer issues and service details digitally

Track the ETA of the service technician in real time

Obtain real-time updates on fleet data

Schedule maintenance and rate service technicians

Phase 1: Design Sprint

Four days from problem to validated prototype

We ran a GV Design Sprint with six Star Leasing stakeholders to rapidly define the problem, explore solutions, prototype, and test with real users—all in four days.

1

Day 1: Define & Solve

Mapped the challenge, identified stakeholder pain points, and produced solution concepts

2

Day 2: Storyboard

Created a detailed storyboard mapping the driver's breakdown experience end-to-end

3

Day 3: Prototype

Built a clickable SBS prototype ready for real-user testing

4

Day 4: Test

Tested with 4 real users (3 drivers + 1 fleet equipment manager) and validated the concept

Key Insight

"Phone is the least efficient form of communication"

— From stakeholder analysis (Coordinator Map)

Design Sprint workshop - whiteboard mapping and team discussion
Validation

Drivers validated it on Day 4

We tested the prototype with 4 users—3 drivers (Adrian, James, Ronney) and 1 fleet equipment manager (Bob Anno)—using a real-world scenario: "Reefer trailer #301239 has broken down due to a blown left rear tire..."

Simple & Intuitive

Users navigated the app without instruction or hesitation

Efficient & Streamlined

Breakdown requests submitted in minutes vs. lengthy phone calls

Increased Visibility

Real-time technician ETA and status updates calmed anxious drivers

High Desirability

Every tester wanted the app deployed immediately

What Drivers Said

"I've trained a third of the drivers here... I don't know any that wouldn't be able to use this."

James — Driver

"Much needed, it would work."

Ronney — Driver

"Good for the driver's state of mind."

James — Driver

"I like the app, I need that."

Ronney — Driver

"I like it, y'all did good."

James — Driver

"Get it rollin'."

Adrian — Driver

The Solution

Roadside rescue in the palm of your hand

With just a few taps, drivers request help, specify the nature of the breakdown, and get real-time updates. The app communicates estimated times and technician locations to manage expectations and promote a sense of calm.

Request Assistance

Submit breakdown details, photos, and location with a few taps—no phone call needed

Assistance Visibility

Track technician assignment, ETA, and real-time location on a live map

Push Notifications

Triggered when a technician is assigned, delayed, or when their ETA has been reached

Network-Adaptive Uploads

Detects bandwidth and adjusts image size automatically for reliable uploads on the road

Architecture

Built for the road, deployed to the cloud

The SBS mobile app connects drivers to Star Leasing's existing StarView system through a secure VPN, with the Rails API and image storage hosted on AWS. The architecture was designed for drivers with unreliable connectivity and enterprise-grade security requirements.

Solution Architecture: React Native mobile app → AWS Cloud (VPC, Elastic Beanstalk, S3) → VPN → Star Leasing Data Center (StarView, MySQL)

Engineering Highlight: Network-Aware Image Uploads

In transportation, image transfer consumes the majority of bandwidth. We architected the app to detect network health and dynamically adjust image size, improving responsiveness and upload success rates for drivers on the road. Images upload asynchronously, separate from the service request payload.

Results

From cost center to digital platform

Eliminated Dispatcher Calls

Drivers submit service requests directly from the app—no more waiting in phone queues

Real-Time Technician ETA

Live tracking and push notifications keep drivers informed and calm

Cross-Platform Launch

Single React Native codebase deployed to both iOS and Android

Cost Center → Profit Center

SBS transformed from operational cost to revenue-generating platform

Foundation for IoT & MGPP

Platform built to support predictive maintenance and driver training

Automated CI/CD Pipeline

Travis CI + CodePush for continuous deployment with automated test suites
