Step 1

Clarify the Question

• Looking at the estimation context, are we focusing on daily active users (DAU) for WhatsApp in India, or should we consider a broader timeframe like monthly active users (MAU)?

Why it matters: Determines the scope of our calculation and affects our approach to user activity. Expected answer: Let's focus on daily active users for a more precise estimate. Impact on approach: We'll need to consider daily usage patterns and peak hours.

• Considering the diverse nature of India's population, should we segment our estimation by urban vs. rural areas or by different age groups?

Why it matters: Different segments may have varying adoption rates and usage patterns. Expected answer: Yes, let's segment by urban and rural populations. Impact on approach: We'll need separate calculations for urban and rural users.

• When we say "WhatsApp chats," are we including all forms of communication (text, voice, video calls) or focusing solely on text messages?

Why it matters: Different types of communication may have different frequencies and durations. Expected answer: Let's focus on text messages for simplicity. Impact on approach: We'll base our calculations on text message frequency and exclude voice/video interactions.
