Metrics are essential to running a business. We all know that. What may not be as obvious, though, is how metrics intersect with your company mission and even employee happiness. Prioritize a single number — to the exclusion of all others — and you’ll invariably leave a lot of people and priorities out. Moreover, you’re likely to constrain your growth. During my time at Airbnb, I lead teams that included product managers, designers, engineers, and data scientists. It would have been impossible to capture the complexities and interactions of their activities with a single metric. Instead, it took a constellation of metrics to capture what the business needed to scale and how each team could facilitate that success.
