🔥 Tier 1 - Must KnowID: northStarMetric
North Star Metric (NSM)
The single key metric that best captures the core customer value delivered and long-term business profit
In Simple Words (Zero Jargon):
The #1 number that the entire company tracks to know if customers are truly getting value (e.g. Airbnb tracks "Nights Booked", Spotify tracks "Time Spent Listening", not just app downloads).
