What factors are contributing to the increased error rates in Haven Technologies's policy administration system API calls this quarter?

Introduction

The increased error rates in Haven Technologies's policy administration system API calls this quarter represent a critical issue that demands immediate attention and a systematic approach to resolution. As we delve into this problem, we'll employ a structured framework to identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

Our analysis will follow a comprehensive approach, starting with clarifying questions to establish context, ruling out external factors, understanding the product and user journey, breaking down the metric, gathering and prioritizing data, forming hypotheses, conducting root cause analysis, and finally, proposing validation methods and next steps.

Clarifying Questions (3 minutes)

• I'm noticing the focus on this quarter. Has there been a gradual increase in error rates, or was it a sudden spike?

Why it matters: This helps determine if it's a recent change or a developing trend. Expected answer: A sudden spike this quarter. Impact on approach: A sudden spike would point to recent changes or events.

• Given the nature of policy administration, I'm wondering about any recent regulatory changes. Have there been any new compliance requirements implemented recently?

Why it matters: Regulatory changes often require system updates that could introduce errors. Expected answer: No significant regulatory changes. Impact on approach: If true, we'd focus more on internal factors rather than external compliance issues.

• Considering the API calls, I'm curious about the distribution of errors. Are they concentrated in specific API endpoints or spread across the system?

Why it matters: This helps narrow down the problem area and potential causes. Expected answer: Errors are concentrated in a few specific endpoints. Impact on approach: We'd focus our investigation on those specific endpoints and their related components.

• Looking at the user base, has there been any significant change in the volume or pattern of API calls from clients?

Why it matters: Changes in usage patterns could stress the system in unexpected ways. Expected answer: No significant changes in overall volume, but some shifts in usage patterns. Impact on approach: We'd investigate how these shifts might be impacting system performance.

• Thinking about system changes, have there been any recent updates to the policy administration system or related infrastructure?

Why it matters: Recent updates are often sources of new issues. Expected answer: A minor system update was deployed at the start of the quarter. Impact on approach: We'd scrutinize this update and its potential impact on the API calls.
