Product Management Root Cause Analysis Question: Investigating increased error rates in post-quantum cryptography system

Introduction

The increased error rates in SandboxAQ's post-quantum cryptography key management system this month present a critical challenge that demands immediate attention. As we delve into this issue, we'll employ a systematic approach to identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

Framework overview

This analysis follows a structured approach covering issue identification, hypothesis generation, validation, and solution development.

Step 1

Clarifying Questions (3 minutes)

  • Looking at the timing, I'm thinking there might be a recent system change. Has there been any significant update or deployment to the key management system in the past month?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a recent update. Impact on approach: If confirmed, we'd focus on the changes made in that update.

  • Considering the nature of post-quantum cryptography, I'm wondering about the scale of the issue. What percentage increase in error rates are we seeing compared to the previous month?

Why it matters: The magnitude helps prioritize the severity and urgency of the problem. Expected answer: A significant increase, perhaps 20-30%. Impact on approach: A larger increase would suggest a more systemic issue rather than normal fluctuations.

  • Given the complexity of quantum-resistant algorithms, I'm curious about the specific types of errors occurring. Are we seeing a particular error type dominating the increase?

Why it matters: Different error types point to different root causes. Expected answer: Yes, there's a predominant error type. Impact on approach: This would narrow our focus to specific components of the system.

  • Thinking about external factors, have there been any notable changes in user behavior or traffic patterns this month?

Why it matters: External changes could be putting unexpected stress on the system. Expected answer: No significant changes noted. Impact on approach: If confirmed, we'd focus more on internal system issues rather than user-related factors.
