Choosing an Appropriate Method for Research

Fuel Payment App Usability Study

Role: Senior UX Researcher
Duration: 6 weeks
Methods: Contextual Inquiry, Usability Testing, Stakeholder Interviews
Team: Product Manager, UX Designer, Developer

Project Overview

The Challenge

The client wanted to find out why people weren't using their fuel payment app as they'd hoped, and to uncover opportunities to increase the uptake of this innovative service.

The Impact

Clear insights into user barriers
Stakeholder buy-in for UX research value
Actionable recommendations delivered
Researcher conducting in-car interview at fuel station

Conducting contextual interviews in participants' vehicles near fuel stations

Defining the Problem

How might we understand the real-world barriers preventing fuel payment app adoption and identify opportunities to improve the user experience?

Initial Constraints

  • Safety concerns: Traditional guerrilla testing at fuel stations posed health and safety risks
  • Limited diversity: Standard recruitment methods might miss key user groups
  • Time pressure: Diary studies would take too long and provide less actionable data
  • Real context needed: Lab testing couldn't replicate the actual fuel station environment

Research Process

01

Method Selection

We wanted to understand how customers usually pay for fuel, and what would enhance their experience. After evaluating multiple approaches, we designed a hybrid method combining contextual inquiry with real-world usability testing.

  • Discounted diary studies due to time constraints
  • Ruled out guerrilla testing for safety reasons
  • Chose in-car contextual approach for safety and authentic context
02

Participant Recruitment

We recruited participants who met us near fuel stations, ensuring we captured diverse user groups and real-world contexts while maintaining safety protocols.

Innovative Approach: Participants joined us in their own cars for interviews, then drove to fuel stations to test the app in real conditions.
03

Data Collection

Each session involved three phases:

  • Setup: Camera positioning and introductions in participant's vehicle
  • Interview: In-depth discussion about current fuel payment habits
  • Testing: Live app usage during actual fuel purchase
  • Debrief: Immediate feedback and wrap-up discussion
04

Analysis & Synthesis

My role as researcher was to ensure participants were comfortable to maximize insights gained, and to closely observe their behavior and external influencing factors.

  • Analyzed both digital interaction patterns and physical environmental factors
  • Identified key friction points in the user journey
  • Mapped external influences (traffic, weather, station layout)

Key Findings

Environmental Context Matters

The forecourt setup significantly impacted user behavior. Busy traffic and crowded stations created stress that affected app usage patterns.

Physical vs. Digital Barriers

Users faced challenges from both app interface issues and real-world factors like pump positioning and payment terminal locations.

Safety First Mindset

Participants prioritized personal safety and quick transactions over exploring new payment methods, especially during busy periods.

Learning Curve Issues

First-time users needed more guidance and reassurance when trying the app in real-world, time-pressured situations.

Results & Impact

Stakeholder Engagement Success

"The study was run seamlessly, the work was well-structured and captivating. Really well-presented research, very clear, very concise, excellent job" — Client Stakeholder

It was important to engage stakeholders during this project, so they could understand the value of user research when making design decisions. We received great feedback especially at the playback, as we demonstrated the strengths of the product and areas of opportunity with clear, actionable outcomes.

Research Methodology Innovation

We were able to observe the physical and digital steps in the experience, and better understand how the forecourt set-up impacted this. The approach gave greater visibility into external factors at each forecourt such as busy traffic and other people, which helped build out insights.

Actionable Recommendations

  • Simplified onboarding flow for first-time users
  • Environmental context considerations for app notifications
  • Integration improvements with fuel station hardware
  • Safety-focused messaging and reassurance features

Key Learnings

Methodological Flexibility

This project reinforced the importance of adapting research methods to specific contexts and constraints. By being flexible and working collaboratively with stakeholders, we designed an approach that was quickly approved and delivered valuable insights.

The Value of Real-World Context

Conducting research in authentic environments revealed insights that wouldn't have emerged in controlled lab settings. The interaction between users, technology, and environmental factors was crucial to understanding the complete user experience.

Stakeholder Education Through Process

By involving stakeholders in the research process and clearly demonstrating our methodology, we successfully built understanding and appreciation for user-centered design principles within the organization.
