Kolkata, West Bengal · Fictional practice case

The decision

A café’s breakfast orders fall from 1,200 to 960 per week. Logs show 180 fewer weekday dine-in orders and 60 fewer delivery orders after a menu update. The owner thinks price is the cause.

What should the research team investigate before reversing the menu update?

Case at a glance
240 weekly orders lost. 180 dine-in. 60 delivery
  1. Segment order loss by store, daypart and channel. Dine-in accounts for 75% of the drop. Check operating hours, stockouts and nearby events.
  2. Observe queues and conduct separate interviews with lost regulars and current customers. Use a small focus group to test language around price and convenience, then compare themes with timestamps.
  3. Pilot a shorter breakfast menu in matched outlets. Track service time and incremental contribution to distinguish preparation delays from price sensitivity.
