Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the API or its dependencies. Has there been any significant update or deployment to the Financial Wellness Coach API in the past month?

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

• Considering the nature of financial APIs, I'm wondering about data volume fluctuations. Have you noticed any unusual spikes in API usage or data processing volume recently?

Why it matters: Unexpected load can strain systems and increase error rates. Expected answer: There's been a 20% increase in API calls this month. Impact on approach: We'd investigate scalability and load handling capabilities.

• Given the integration aspect, I'm curious about partner systems. Have any of our key integration partners reported issues or made changes to their systems recently?

Why it matters: Partner system changes can impact API performance. Expected answer: One major partner upgraded their system last week. Impact on approach: We'd examine the compatibility of our API with the partner's new system.

• Thinking about the error rates specifically, I'm wondering about the nature of these errors. Are we seeing any patterns in the types of errors being reported?

Why it matters: Error patterns can point to specific system components or processes. Expected answer: There's been an increase in timeout errors and data validation failures. Impact on approach: We'd focus on network infrastructure and data processing logic.
