Summary

Product sense question at Google, one question about evaluating a platform change for Instagram's messaging. Pretty open-ended, no obvious right answer, which made it harder than it looked.

Suggested Approach

Start by clarifying the goal and scope of opening Instagram's messaging to third-party businesses, then evaluate the idea against user needs, business value, and strategic fit. Use a structured framework to assess desirability, feasibility, and viability, considering risks and trade-offs. Conclude with a recommendation and potential next steps.

Pro tip: Anchor your evaluation in Instagram's core value proposition of connecting people and businesses, and explicitly discuss how this feature could enhance or dilute that. Show awareness of platform dynamics and the importance of maintaining user trust.

1. Clarify Objectives and Scope

Define what 'opening up messaging' means: which businesses, what types of interactions, and what success looks like. Align with Instagram's mission and Google's principles.

2. Assess User Needs and Desirability

Evaluate whether users want to interact with businesses in messaging, considering existing behaviors and pain points. Segment users (consumers and businesses) and identify use cases.

3. Evaluate Business and Strategic Value

Analyze potential revenue streams, competitive positioning, and ecosystem effects. Consider how this fits with Instagram's monetization strategy and Google's broader goals.

4. Analyze Feasibility and Risks

Assess technical, operational, and regulatory challenges, including privacy, spam, and platform integrity. Consider resource requirements and potential unintended consequences.

5. Synthesize and Recommend

Weigh pros and cons, propose a go/no-go decision with conditions, and suggest metrics for validation. Outline a phased approach if appropriate.

Key Points to Mention

  • User trust and privacy: ensuring messages from businesses are not spammy and user data is protected.
  • Monetization opportunities: potential for ads, transaction fees, or premium business features.
  • Competitive landscape: how this compares to WhatsApp Business, Facebook Messenger, and other platforms.
  • Ecosystem effects: impact on Instagram's core social experience and potential cannibalization.
  • Technical and operational challenges: API design, scalability, and moderation.
  • Success metrics: engagement, business adoption, revenue, and user satisfaction.
