Problem statement
Quality control is essential for maintaining brand standards across all locations of this fast food restaurant chain. However, inspectors faced inefficiencies due to manual processes, rigid workflows, and a lack of flexibility when conducting restaurant evaluations.
The outcome
I designed a mobile-first Quality Control App that seamlessly integrates into Burger King’s digital ecosystem.
The goal
Enhance efficiency, simplify inspections, and empower inspectors with a flexible, user-friendly experience.
Key UX Enhancements
Iteration & User-Centered Refinements
Using guerrilla testing feedback, I iterated on the design:
From version #1
Low-Fi Prototype​
To version #3
Hi-Fi Screen Design
Improve
Navigation
-
Customizable Workflow
​Introduced a task overview screen for flexible step selection. Inspectors could choose their own order of tasks.
Faster Rating Process
-
Streamlined Rating System
Reduced interactions & Faster scoring with consolidated feedback fields.
Increased Timer Visibility
-
Persistent Timer
Accessible from any screen
for more flexible inspections.
Add Transparency
-
Dispute Feature
Managers could now contest results, adding transparency.
These refinements prioritized user control and efficiency, making the app intuitive and seamless for inspectors.
Discover
Research
For Broadening the scope to understand the problem.
Define
Synthesis
Narrowing the scope and defining the problem.
​
Develop
Ideation
Generating ideas to solve the problem, prototyping and user testing.
Deliver
Implementation
Delivering a design based on testing, iteration and user insights.
The Design Process
From Concept to High-Fidelity Prototype
At the beginning, I started with a benchmarking research, low-fidelity sketches, iterating through multiple layouts based on feedback. As the design evolved, I developed a Design System incorporating:
-
Burger King’s Visual Identity
Maintaining brand consistency.
-
Typography & Color Palette
Ensuring clarity and accessibility.
-
Component library
For scalability and consistency.
Competitive analysis. Benchmarking
Before designing the App, I conducted a benchmarking research to analyze both direct and indirect competitors across B2B and B2C industries. This process helped identify best practices, user expectations, and opportunities to create a more efficient and user-friendly inspection tool.

Research & Key Insights
To ensure the app truly met inspectors' needs, I conducted guerrilla usability testing with participants who simulated real inspections using my prototype. The insights were eye-opening:
01. Timer Flexibility
Users wanted to start the timer and continue other tasks, rather than following a fixed sequence.
02. Navigation Preferences
Some inspectors preferred a non-linear workflow, choosing which steps to complete first.
03. Speed & Simplicity in Ratings
The original rating system felt slow; inspectors needed a quicker way to evaluate restaurants.
04. Decision Transparency
Managers requested an option to dispute inspection results, ensuring fairness in evaluations.
Miro board with main insights
These insights directly shaped the app’s core functionalities, leading to meaningful improvements in usability and efficiency.
Impact
The Results & Takeaways
The final high-fidelity prototype provided a faster, more efficient, and user-friendly solution for Burger King inspectors.
Key learnings:
-
User feedback is essential
Small tweaks (like a persistent timer) significantly improve usability.
-
Flexibility matters
Allowing inspectors to customize their workflow enhanced efficiency.
-
Testing early saves time
Validating with users early prevented unnecessary iterations later.
Through this project, I strengthened my skills in UX research, interaction design, design systems and prototyping, while crafting a solution that seamlessly integrates into Burger King’s ecosystem.
What’s Next?
In future iterations, I’d like to:
-
Conduct further testing with a larger sample size to refine usability.
-
Explore data visualisation in this project & data analytics to track inspector efficiency and improve decision-making. Keep working on the History, Profile & Calendar section.
