Metrics are quantitative measures used to assess, compare, and track performance or progress in various fields. They provide a way to evaluate success by using specific data points, such as sales figures, website traffic, or customer satisfaction scores. By analyzing these numbers, organizations can make informed decisions and identify areas for improvement. In business, metrics can include key performance indicators (KPIs) that help gauge the effectiveness of strategies and operations. For example, a company might track metrics like conversion rates or return on investment (ROI) to understand how well their marketing efforts are performing. These insights guide future actions and resource allocation.
