Your manager at Google asks about Gmail: should we increase attachment size limits while potentially slowing email delivery, or maintain current limits with faster delivery?

Introduction

The trade-off we're considering for Gmail is whether to increase attachment size limits at the potential cost of slower email delivery, or maintain current limits to ensure faster delivery. This scenario touches on key aspects of user experience, technical infrastructure, and product strategy. I'll analyze this trade-off by examining user needs, technical constraints, business implications, and potential experiments to inform our decision.

Clarifying Questions (3 minutes)

• Based on recent user feedback, I'm thinking this might be driven by changing user needs. Could you share any insights on user complaints or requests regarding attachment sizes?

Why it matters: Helps understand the urgency and scale of the problem Expected answer: Increasing requests for larger attachments, especially for work-related files Impact on approach: Would prioritize user satisfaction in the decision-making process

• Considering our competitive landscape, I'm curious about our position relative to other email providers. How do our current attachment limits compare to major competitors like Outlook or Yahoo?

Why it matters: Informs our competitive strategy and potential user churn risks Expected answer: We're slightly behind or on par with competitors Impact on approach: Might lean towards increasing limits to stay competitive

• From a technical perspective, I'm wondering about our current infrastructure capacity. What's our current utilization rate for email processing and storage?

Why it matters: Determines the feasibility and cost of increasing attachment sizes Expected answer: Moderate to high utilization, but with some room for growth Impact on approach: Would need to consider infrastructure upgrades in the cost-benefit analysis

• Thinking about our business model, how does email delivery speed currently factor into our key performance indicators or user satisfaction metrics?

Why it matters: Helps weigh the importance of maintaining current delivery speeds Expected answer: Speed is a key differentiator and strongly correlates with user satisfaction Impact on approach: Would need to carefully balance any speed trade-offs against potential benefits

• Considering our product roadmap, are there any upcoming features or integrations that might be affected by or benefit from larger attachment sizes?

Why it matters: Ensures alignment with broader product strategy Expected answer: Potential integrations with Google Drive or other cloud storage solutions Impact on approach: Might influence the timing or implementation of the change
