Key Performance Indicators (KPIs) keep track of important measurements to help businesses make critical decisions. KPIs should relate to your business goals and help you understand how to achieve those goals. KPIs are also metrics, but not all metrics are key performance indicators. Metrics measure how the business is doing in a specific area. KPIs are metrics that are the most essential for your business. Common KPIs tracked by companies are Revenue Growth and Profit Margins. But key performance indicators in production help ensure optimization in that area.
