To measure the success of TurboTax, I would first clarify the specific product or feature in question and its primary objective. Then, I'd map out the user journey to understand key interaction points. Based on the goal, I'd identify and prioritize metrics across several categories:
- User Acquisition & Engagement: Track new user sign-ups, active users (daily/monthly), session duration, and feature adoption rates.
- Task Completion & Success: Measure the percentage of users who successfully complete their tax filing, time taken to file, and error rates during the process.
- Customer Satisfaction & Retention: Monitor Net Promoter Score (NPS), customer satisfaction (CSAT) surveys, churn rate, and repeat usage for subsequent tax years.
- Business & Financial: Analyze conversion rates from free to paid tiers, average revenue per user (ARPU), and overall revenue generated.
I would prioritize metrics that directly reflect the core value proposition – helping users file their taxes accurately and efficiently – while also considering business objectives.
