Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the tool or its environment. Has there been any significant update or deployment to the data discovery tool in the past quarter?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a major update. Impact on approach: If yes, we'll focus on the changes made; if no, we'll look at external factors or gradual degradation.

• Considering the nature of data discovery, I'm wondering about data volume and complexity. Have there been any notable changes in the data sources or volume being processed by the tool?

Why it matters: Changes in data characteristics can affect tool performance. Expected answer: There's been an increase in data volume and complexity. Impact on approach: If yes, we'll investigate scalability issues; if no, we'll look at other potential causes.

• Given that this is a sudden increase, I'm curious about the user behavior. Have we seen any changes in how users are interacting with the tool or in the types of queries they're running?

Why it matters: User behavior can significantly impact system performance. Expected answer: Users are running more complex queries. Impact on approach: If yes, we'll focus on query optimization; if no, we'll look at system-level issues.

• Thinking about the broader ecosystem, I'm wondering if there have been any changes in the infrastructure or dependencies of the data discovery tool?

Why it matters: External dependencies can introduce new points of failure. Expected answer: Some infrastructure upgrades were made. Impact on approach: If yes, we'll investigate integration issues; if no, we'll focus more on the tool itself.
