Suggested Approach

Start by clarifying the goal and constraints of the ATM, then segment users based on their needs at Heathrow (e.g., arriving/departing passengers, staff). Focus on designing a solution that addresses the unique pain points of an airport environment, such as currency exchange, quick transactions, and integration with travel services.

Pro tip: Emphasize the importance of adaptability: design the ATM to handle multiple currencies and integrate with mobile apps for seamless transactions, but also consider backup systems for connectivity issues. Show awareness of Google's ecosystem by suggesting features like Google Pay integration.

1. Clarify Objectives and Constraints

Ask clarifying questions to understand the scope: Is this a physical ATM or a digital interface? What are the key goals (e.g., convenience, speed, multi-currency)? What constraints exist (space, regulations, security)?

2. Identify User Segments and Needs

Segment users by traveler type (international arrivals, departures, transit, staff) and identify their primary needs: currency exchange, cash withdrawal, bill payment, etc. Prioritize needs based on frequency and urgency.

3. Brainstorm Features and Solutions

Generate ideas for features that address user needs, such as multi-currency dispensing, mobile wallet integration, real-time exchange rates, and quick transaction modes. Consider innovative features like pre-ordering currency via app.

4. Prioritize and Define MVP

Evaluate features based on impact and feasibility. Define a minimum viable product (MVP) that includes core functionalities (e.g., cash withdrawal in multiple currencies) and high-impact differentiators (e.g., seamless app integration).

5. Consider Implementation and Metrics

Discuss how to implement the solution (hardware, software, partnerships) and define success metrics (e.g., transaction time, user satisfaction, adoption rate). Mention potential challenges like security and connectivity.

Key Points to Mention

  • Multi-currency support with competitive exchange rates
  • Integration with mobile wallets (Google Pay, Apple Pay) and airline apps
  • Fast transaction modes for quick withdrawals (e.g., tap-and-go)
  • Accessibility features for international users (language options, clear instructions)
  • Security measures (biometric authentication, fraud detection)
  • Partnerships with local banks and currency exchange services for liquidity
