The Background

Before we begin...can everyone see my screen?

While earning my Professional UX Design Certificate from Google, I was challenged to design a simple mobile app for electricians, which led to the creation of Swift Spark. This conceptual project focused on streamlining the process of finding and booking trustworthy electrical services.

The Challenge

Booking Electricians Shouldn’t Be This Hard

Booking an electrician is often slow and confusing, especially in an emergency, with unclear pricing and surprise fees. Homeowners can’t verify an electrician’s experience or reliability without trust signals. The result is frustration and uncertainty.

Time-Consuming Booking Process

It can be tedious to find the ideal electrician, book an appointment, and confirm service details, especially in an emergency

Unclear Pricing & Hidden Fees

Homeowners experience inconsistent service transparency, often leading to unexpected fees or upselling

Unproven Credibility & Reliability

Homeowners want a trustworthy booking platform that ensures the credibility and reliability of electricians

The Solution

Swift Spark: Fast, Transparent, and Trustworthy

Swift Spark is designed to connect homeowners with trusted electricians through a user-friendly experience. Prioritizing transparency, efficiency, and convenience, the app ensures users can quickly find qualified professionals while electricians gain a reliable platform to manage bookings.

Quick-Action User Interface

Support homeowners through straightforward navigation, prominent action buttons, and minimal industry jargon

Flat-Rate Pricing Structure

Implement one flat-rate fee for all services booked through the app to provide the exact cost upfront with no hidden fees or charges

Verification and Reviews

Display credentials and reviews of verified electricians to promote trust and improve research efficiency

Understanding Current Frustrations

I conducted user interviews and foundational research to uncover key pain points, motivations, and potential solutions. I interviewed eight homeowners to understand their current process for finding reliable electricians.

Additional research included analyzing industry reports and conducting a competitive audit of four direct and indirect competitors.

Tedious Processes

5 out 8 homeowners felt overwhelmed with their current process of searching multiple platforms and cross-checking references before booking an electrician

Busy Schedules

6 out of 8 homeowners struggled to find a convenient time within their busy day-to-day lives to coordinate appointments for maintenance work

Fear of Deception

5 out of 8 homeowners reported feeling confused, discouraged, or deceived when communicating with electricians due to unfamiliarity with pricing or industry jargon

Quality Assurance

7 out of 8 homeowners shared concerns that poor quality work will waste time and money, leaving them with a bigger headache than the original problem

Defining the Problem

Meet Hannah: The Busy Homeowner

I turned research into a clear problem statement, user persona, and key challenges to tackle. This helped shape Swift Spark’s approach to solving user pain points. I identified two main user groups: Homeowners and Contractors. Homeowners need reliable electricians for one-time repairs, while Contractors look for ongoing project support.
To keep users at the center, I created Hannah Holmes, a persona representing busy homeowners who value efficiency and a hassle-free way to book electricians.

The Problem Statement

Hannah Holmes is a busy homeowner with a demanding job and family responsibilities. She needs to easily schedule an electrical repair for her flickering lights, because she wants to have a safe and comfortable home environment without disrupting her tight schedule.

Brainstorming impactful solutions

I explored creative design solutions for Swift Spark, using research insights to shape key features and user flows. To refine the design, I held a card-sorting session with participants to prioritize features based on homeowner needs.

I iterated through low-fidelity digital sketches of key screens, using early user feedback to remove bias and ensure the app effectively meets user needs at every step.

Prototype

Bringing Ideas to Life

This phase involved prototyping user flows of key screens and refining interactions to ensure a seamless experience. I prioritized clarity, ease of use, and accessibility, laying the foundation for a functional and user-friendly app.

Test

Refining Through User Feedback

I conducted moderated usability tests with four participants and impromptu hallway testing with a Home Depot customer. Participants completed specific tasks while I documented their interactions, feedback, and pain points.

To gather measurable insights, participants also filled out a System Usability Scale (SUS) form, helping to refine the app’s usability and overall experience.

Here’s an overview of the testing process:

Key Feedback That Refined the Vision

Based on user feedback, I made several key design improvements to enhance usability and accessibility:

Key Takeaways

User-Centered Design Drives Success

Swift Spark’s design process reinforced the power of user feedback and data-driven decisions. I refined the app design while eliminating bias, ensuring it meets real user needs. This experience highlighted the importance of user-centered design for accessibility and overall engagement.

Some Fun Extras

Although Swift Spark is only a conceptual mobile app project, I created a brand style guide to maintain consistency throughout the design process.

I also designed Swift Spark in other everyday scenarios to fully bring the concept to life.
