Introduction

A sudden 30% decrease in live streaming engagement on Kuaishou's platform yesterday evening is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term and long-term implications for the platform's success.

I'll approach this problem by first clarifying key details, ruling out external factors, and then diving deep into the product ecosystem, user journey, and relevant metrics. From there, I'll generate data-driven hypotheses, conduct root cause analysis, and propose a structured plan for validation and resolution.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a specific event or content type. Was there any major live streaming event scheduled for yesterday evening?

Why it matters: Understanding if this was tied to a specific event helps narrow down potential causes. Expected answer: Yes, there was a major celebrity live stream event. Impact on approach: If yes, we'd focus on event-specific factors; if no, we'd look at broader platform issues.

• Given the significant drop, I'm wondering about technical issues. Have we confirmed that all systems were functioning normally during this period?

Why it matters: Technical problems could explain a sudden, large-scale engagement drop. Expected answer: No major outages or errors were reported. Impact on approach: If technical issues are confirmed, we'd prioritize infrastructure analysis; if not, we'd focus more on content or user behavior factors.

• Considering user segments, I'm curious if this decrease was uniform across all user groups. Do we have data on which user segments were most affected?

Why it matters: Identifying specific affected segments could point to targeted issues or changes. Expected answer: The decrease was more pronounced among younger users. Impact on approach: If specific segments were more affected, we'd investigate factors unique to those groups; if uniform, we'd look at platform-wide issues.

• Thinking about recent changes, I'm wondering if any new features or updates were rolled out recently. Have there been any significant platform changes in the past week?

Why it matters: Recent changes could have unintended consequences on user engagement. Expected answer: A new recommendation algorithm was implemented two days ago. Impact on approach: If recent changes are identified, we'd focus on their impact; if not, we'd look at other factors affecting engagement.
