The sample file process-mining-pizza.csv is one pizzeria evening: 36 orders. Customers order in the app, pay, the kitchen prepares, then the order is handed to a courier or the pickup desk.
The question to keep: why does delivery take longer than pickup? Pickup is not a different product — it is a second path after payment.
Every row is one step of one order. You will map Case ID = case_id, Activity = activity, Timestamp = timestamp. Extra columns in the CSV (zone, customer type, order value) describe the order. They are not Data Filter fields in the workspace.
Activity names include 5A. Order accepted by pizzeria and 5B. Pickup confirmed. Payment notes in the file say payment completed once — do not look for payment rework that is not there.
Download the CSV and analyze it yourself in the next lesson. Numbers from Log overview belong after Analyze, not before.
