Assessing Impact of ETA Range on Ridership

Requirements Clarification & Assessment

1. Objective Clarification:

   • Understand the primary goal: To determine if displaying ETA as a range impacts ridership positively.
   • Define what "boost in ridership" means: Is it increased bookings, reduced cancellations, or higher customer satisfaction?

2. Scope of Change:

   • Confirm if the change affects only the pre-booking ETA display or both pre- and post-booking.
   • Determine the geographical scope: Will this be tested globally, nationally, or in specific regions?

3. Metrics Definition:

   • Primary Success Metric: Conversion rate from viewing ETA to booking.
   • Secondary Metrics:
     • Number of bookings per user.
     • Cancellation rate.
     • Revenue per day.
     • User satisfaction ratings (if available).

4. Constraints and Limitations:

   • Ensure the technical feasibility of implementing a range-based ETA display.
   • Identify any existing data limitations or biases that might affect the experiment results.

5. Hypothesis Development:

   • Null Hypothesis $H_0$: Displaying ETA as a range does not affect ridership metrics.
   • Alternative Hypothesis $H_A$: Displaying ETA as a range positively affects ridership metrics.
