Secondary Research

Building Domain Knowledge Through Secondary Research

To understand the market, we began with secondary research, reviewing open-source studies and research papers on backpacker behavior, budgeting patterns, and food choices. We found that many Gen Z backpackers face unique challenges when it comes to eating in Thailand.

Key Findings: Language and Safety Barriers

Our research revealed that language is a significant obstacle, as many Thai street food vendors don’t speak English or provide English menus. Despite street food being a budget-friendly and authentic option, only 8% of travelers regularly eat it. This is surprising given that 80% say they enjoy Thai street food. The main deterrents are language barriers and safety concerns—63% worry about hygiene, even though contamination levels are low and comparable to restaurants.

Ecosystem Map

Travelers default to famaliar options such as fast food chains or convenience stores

Using insights from research, we created an ecosystem map—a visual representation of how travelers interact with food-related touchpoints along their journey, both physical and digital. This map allowed us to capture a high-level view of their behaviors. We found that many travelers rely on hostel staff or peers for recommendations, but when unsure, they default to familiar options such as fast food chains or convenience stores like 7-Eleven.

Solution 1

Opting for a solution that balances user needs and operational effort.

We first ideated solutions individually, then regrouped to select the best ideas from our brainstorming session. Two concepts emerged. The first proposed highlighting nearby street food stalls certified by Lonely Planet for cleanliness and streamlining orders with POS devices. While this solution could address user concerns from a design perspective, it may require significant resources and be unviable to certify every stall in Bangkok and manage the ordering process at scale.

Solution 2

Opting for Interactive and comprehensive Street food guide

For another direction, we approached the problem differently. In Thailand, there are roughly 100 popular street food dishes, which can be grouped into seven main categories.

This led us to ask: What if we created a street food guide that highlights natural hygiene risk levels and ingredients for each dish?

Final Concept is Yummie Street

An app that not only reduce food safety concerns but also helps backpackers learn about dishes, customize orders, and collect Thai street food experiences like treasures—all while remaining lightweight from both business and technical perspectives.

Usability testing

Although We Have a High SUS, Many Users Aren’t Willing to Promote Our App

We conducted a usability test with six participants to evaluate the onboarding and food customization flows. The goal was to understand user perceptions, identify usability issues, and measure the overall user experience of the app.

We conducted a usability test with six participants to evaluate the onboarding and food customization flows. The goal was to understand user perceptions, identify usability issues, and measure the overall user experience of the app.

While users were able to complete tasks successfully, several areas caused confusion or hesitation. Participants expected more interactive elements during onboarding and had trouble understanding certain customization options. Some found the “make it your own” button unclear, while others wanted more flexibility in food restriction choices.
