Suggested Approach

Start by clarifying WhatsApp's core value proposition and business model, then define KPIs across the user journey (acquisition, engagement, monetization, and ecosystem health). Prioritize metrics that reflect WhatsApp's unique strengths like privacy, reliability, and global scale, and tie them to Meta's strategic goals.

Pro tip: Emphasize that WhatsApp's KPIs must balance user trust and monetization, avoiding metrics that incentivize spam or privacy erosion. Show you understand the trade-offs between growth and user experience.

1. Clarify Objectives and Context

Ask clarifying questions about WhatsApp's current priorities (e.g., growing business messaging, increasing engagement in emerging markets) and Meta's overarching goals. This ensures your KPIs align with strategic focus.

2. Map the User Journey

Break down the user journey into stages: acquisition, activation, engagement, retention, monetization, and referral. This helps structure KPIs comprehensively.

3. Define KPIs per Stage

For each stage, propose specific KPIs. For example, acquisition: new user growth rate; engagement: daily active users (DAU), messages sent per user; monetization: business messaging revenue, conversion rates.

4. Prioritize and Set Targets

Select the most critical KPIs based on impact and alignment with goals. Suggest targets or benchmarks, considering WhatsApp's scale and regional differences.

5. Monitor and Iterate

Explain how you would track these KPIs over time, set up dashboards, and use them to inform product decisions and experiments.

Key Points to Mention
