Determine North-Star Metric for CloudTrucks Driver Platform
Product Analytics Case: North-Star Metric and Booking Funnel (Driver Platform)
Context
You are tasked with evaluating the health of a trucking marketplace's driver platform. You have direct warehouse access to three core tables, each containing standard identifiers and timestamps. The minimum schema for these tables is as follows:
- drivers:
driver_id,onboarded_at,status - jobs:
job_id,posted_at,pickup_at,dropoff_at,origin,destination,payout_amount - loads:
load_id,job_id,driver_id,status,requested_at,offered_at,accepted_at,picked_up_at,delivered_at,canceled_at,payout_amount
Task
- North-Star Metric Selection: Choose and provide a comprehensive justification for a single North-Star Metric specifically for the driver platform. Your explanation must detail why this metric is both actionable and leading.
- Metric Calculation (SQL): Using the provided table schemas, write a SQL query to calculate your chosen North-Star Metric on a weekly basis.
- Funnel Analysis Design: Describe a detailed funnel analysis for the driver job-booking flow. This description should clearly specify the key stages of the funnel, identify the critical drop-off points you would measure, and explain how these measurements connect directly to business outcomes.

Core dilemma
The central engineering conflict is balancing the need for a single, unifying North-Star Metric that truly reflects driver platform health and business value, against the complexity of driver behavior, potential for metric manipulation, and the inherent tradeoffs between different aspects of platform success (e.g., driver earnings vs. platform efficiency vs. retention). The challenge extends to designing a robust, scalable, and accurate analytical framework (SQL, funnel) that can reliably measure and inform strategic decisions.
