A Metric is a tool for measuring. On WikiRate, metrics are used to measure company performance, and they are a way of asking the same question of many companies. It consists of a question, an About section (which describes why this metric is important and how it is used), and a Methodology section (which describes how to research the answer).
Some metric answers are researched, and their values and source citations are entered directly. Other answers are dynamically calculated from other answers.
