“ Analytics are a 25-40% tax on your product development process. They take engineers lots of time and development effort, produce numbers that people argue about, and require additional infrastructure.

Having 1 in 4 engineers working on analytics may seem like a ton, but it helps validate assumptions, pinpoint key features and bottlenecks, model the business during decision-making. At the cost of building fewer features, learn as much as you can so that you can “run up the score” on the features that work.
