Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent system update. Have there been any significant changes to our delivery management system in the past two weeks?

Why it matters: System changes often have unintended consequences on delivery performance. Expected answer: Yes, there was a minor update to route optimization. Impact on approach: If confirmed, we'd focus on technical issues related to the update.

• Considering user segments, I'm curious if this increase is uniform across all customer types. Are we seeing a disproportionate increase in tickets from any particular user segment, such as first-time customers or those in specific geographic areas?

Why it matters: This helps us narrow down whether it's a systemic issue or related to specific user groups or regions. Expected answer: The increase is more pronounced in urban areas. Impact on approach: We'd investigate urban-specific factors like traffic patterns or local events.

• Given the sudden nature of the increase, I'm wondering about our delivery partner network. Has there been any significant change in our delivery workforce or partner relationships recently?

Why it matters: Changes in our delivery network could directly impact our ability to meet delivery promises. Expected answer: No major changes, but there's been some turnover in delivery partners. Impact on approach: We'd look into training and onboarding processes for new delivery partners.

• Considering potential changes in customer behavior, have we recently run any major marketing campaigns or promotions that could have led to an unexpected surge in orders?

Why it matters: A sudden increase in order volume could strain our delivery capacity. Expected answer: There was a flash sale last week. Impact on approach: We'd analyze our capacity planning and demand forecasting processes.
