How would you measure the success of Google Pay/Wallet?

Introduction

Measuring the success of Google Pay/Wallet requires a comprehensive approach that considers multiple stakeholders and the product's evolving role in Google's ecosystem. To address this product success metrics challenge, I'll follow a structured framework covering core metrics, supporting indicators, and risk factors while considering all key stakeholders.

Step 1

Product Context (5 minutes)

Google Pay/Wallet is a digital payment and financial management platform that allows users to make payments, store cards and passes, and manage their finances. Key stakeholders include:

1. Users: Seeking convenient, secure payment methods and financial management tools
2. Merchants: Looking to increase sales and streamline transactions
3. Financial institutions: Aiming to increase card usage and customer engagement
4. Google: Expanding its ecosystem and gathering valuable user data

User flow typically involves:

1. Adding payment methods (credit cards, bank accounts)
2. Making payments (in-store, online, peer-to-peer)
3. Managing finances (viewing transactions, budgeting)

Google Pay fits into Google's broader strategy of creating a comprehensive ecosystem of services, enhancing user data collection, and competing in the fintech space. It competes with other digital wallets like Apple Pay and PayPal, as well as traditional payment methods.

In terms of product lifecycle, Google Pay is in the growth stage, continuously expanding features and user base.

Software-specific context:

• Platform: Mobile (Android, iOS) and web
• Integration points: Payment gateways, banking systems, merchant POS
• Deployment model: Cloud-based with regular updates

Goals (4 minutes)

Step 3

North Star Metric (5 minutes)

Proposed North Star Metric (NSM): Monthly Active Transacting Users (MATU)

Definition: The number of unique users who complete at least one transaction through Google Pay in a given month.

Calculation: Count of unique user IDs with at least one successful transaction in the past 30 days.

This metric best captures success because it combines user acquisition, retention, and engagement. It reflects value for all stakeholders:

• Users: Indicates the product's utility and ease of use
• Merchants: Represents potential customers
• Financial institutions: Reflects active card usage
• Google: Demonstrates ecosystem engagement and data generation

Hypothetical data: If MATU increases from 50 million to 60 million over a quarter, it would indicate strong growth in adoption and usage. A decline might suggest user churn or competitive pressure.

Breakdown North Star Metric

MATU can be broken down into:

1. User Acquisition (UA)
2. User Retention (UR)
3. Transaction Frequency (TF)

Formula: MATU = f(UA, UR, TF) UA = f(Marketing Effectiveness, Onboarding Success Rate) UR = f(User Satisfaction, Feature Engagement) TF = f(Use Case Diversity, Transaction Value)

Step 4

Supporting Metrics (6 minutes)

Step 5

Guardrail Metrics (5 minutes)

Payment Success Rate is crucial as it directly impacts user trust and satisfaction. A high success rate (>99.9%) ensures users can rely on Google Pay for their transactions, which in turn positively affects the MATU.

Transaction Processing Time is vital for merchant satisfaction and user experience. Fast processing (<2 seconds) encourages both merchants and users to prefer Google Pay over other payment methods, contributing to increased transaction volume and MATU.

Fraud Rate is critical for maintaining trust with financial institutions and users. A low fraud rate (<0.1%) ensures continued support from banking partners and user confidence, both of which are essential for sustaining and growing the MATU.

Data Privacy Compliance is non-negotiable in today's regulatory environment. 100% compliance protects Google from legal issues and maintains user trust, which is fundamental to retaining and growing the user base reflected in the MATU.

Step 6

Trade-off Metrics (4 minutes)

1. User Acquisition vs. User Retention

   • Trade-off: Focusing on acquiring new users may come at the expense of retaining existing ones.
   • Balance: Allocate resources to both acquisition and retention efforts, using cohort analysis to optimize strategies.

2. Feature Richness vs. App Performance

   • Trade-off: Adding new features may increase app complexity and potentially slow performance.
   • Balance: Prioritize features based on user demand and impact, while continuously optimizing app performance.

3. Transaction Volume vs. Fraud Prevention

   • Trade-off: Stricter fraud prevention measures might reduce overall transaction volume.
   • Balance: Implement risk-based authentication, using machine learning to minimize friction for low-risk transactions while maintaining security.

Step 7

Counter Metrics (4 minutes)

1. User Churn Rate

   • Purpose: Identifies the rate at which users stop using Google Pay.
   • Avoiding pitfalls: Prevents overemphasis on new user acquisition at the expense of retention.
   • Actions: If increasing, investigate reasons through user surveys and improve retention strategies.

2. Failed Transaction Rate

   • Purpose: Monitors the reliability and user experience of the payment system.
   • Avoiding pitfalls: Ensures focus on transaction quality, not just quantity.
   • Actions: If rising, investigate common failure points and improve system reliability.

3. Customer Support Volume

   • Purpose: Indicates overall product health and user satisfaction.
   • Avoiding pitfalls: Prevents neglecting user experience in pursuit of growth.
   • Actions: If increasing, analyze common issues and improve self-service options or product features.

Strategic Initiatives

1. Expand Contactless Payments Infrastructure

   • Rationale: Increases convenience and usage opportunities for users.
   • Impact: Could significantly boost Transaction Frequency and Total Transaction Volume.
   • Challenges: Requires partnerships with merchants and investment in hardware.

2. Introduce AI-Powered Financial Insights

   • Rationale: Enhances value proposition beyond payments, improving retention.
   • Impact: Could increase User Retention Rate and Feature Adoption Rate.
   • Challenges: Ensuring data privacy and developing accurate, helpful insights.

3. Launch Cross-Border Payment Capabilities

   • Rationale: Expands use cases and attracts new user segments.
   • Impact: Could increase User Acquisition and Average Revenue Per User.
   • Challenges: Navigating international regulations and managing currency exchange risks.

Conclusion

Emerging technologies like blockchain and AI could significantly impact Google Pay's future. Success metrics may need to evolve to capture new forms of value creation, such as decentralized finance integration or predictive financial planning effectiveness.
