North Star Metric
A North Star Metric (NSM) is a key metric chosen by a company with the aim of leveraging results and focusing on what really matters. Using a North Star Metric is a way to measure the company's progress with a focus on sustainable business growth. It can be classified as an Output metric as it is the result of different smaller activities that can be measured by other metrics – Input metrics – and which together aim to achieve a specific result and make an impact. Some examples of North Star Metrics from famous companies are the time people spend on the platform watching movies and TV shows (Netflix) and the number of active users per month (Facebook).
