how would you define the success of whatsapp's voice messaging function?

Introduction

Defining the success of WhatsApp's voice messaging function requires a comprehensive approach that considers multiple stakeholders and metrics. To tackle 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

WhatsApp's voice messaging function allows users to record and send audio messages within the app. This feature caters to users who prefer speaking over typing, enhancing communication in situations where typing is inconvenient or time-consuming.

Key stakeholders include:

• Users: Seeking efficient, expressive communication
• WhatsApp (Meta): Aiming to increase user engagement and retention
• Advertisers: Interested in user activity and engagement data
• Telecom providers: Concerned about data usage and potential impact on traditional voice calls

User flow:

1. User opens chat and taps microphone icon
2. Records message by holding the icon
3. Releases to send or swipes up to lock for hands-free recording
4. Recipient plays message with a single tap

This feature aligns with WhatsApp's strategy of providing versatile communication options within a single platform. Compared to competitors like Telegram or Signal, WhatsApp's voice messaging is more seamlessly integrated and user-friendly.

Product Lifecycle Stage: Mature - The feature has been widely adopted and is now in a phase of incremental improvements and optimizations.
