Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has there been any significant change in order volume or customer demographics compared to the same quarter last year?

Why it matters: Seasonal variations could explain satisfaction changes and impact our solution approach. Expected answer: Order volumes are consistent with last year, but there's been a slight shift towards younger customers. Impact on approach: If confirmed, we'd need to investigate whether the service is meeting the expectations of this younger demographic.

• Considering the specificity of the 15% drop, I'm curious about the measurement methodology. Has there been any recent change in how customer satisfaction is measured or calculated?

Why it matters: Changes in measurement could artificially inflate the perceived issue. Expected answer: No changes in measurement methodology. Impact on approach: If confirmed, we can focus on actual service issues rather than measurement discrepancies.

• Given the competitive nature of online grocery, I'm wondering about recent moves by competitors. Have any major competitors launched new features or pricing strategies in the past quarter?

Why it matters: Competitive pressures could be driving customer expectations and impacting satisfaction. Expected answer: One competitor introduced free next-day delivery for orders over £50. Impact on approach: This would prompt us to examine our delivery options and pricing strategy.

• Considering the complexity of online grocery systems, I'm thinking about recent technical changes. Have there been any significant updates to the website, app, or backend systems in the last quarter?

Why it matters: Technical issues could directly impact user experience and satisfaction. Expected answer: A new inventory management system was implemented two months ago. Impact on approach: This would lead us to investigate potential issues with stock accuracy and availability.
