A Key Performance Indicator (KPI) System is an information management tool used to track and analyze the performance of an organization or business. KPIs provide a quick, easy-to-understand overview of how well a company is doing in key areas such as sales, customer satisfaction, product quality, and operational efficiency. By regularly monitoring KPIs and reviewing the data that they provide, businesses can make informed decisions about where to focus their efforts in order to maximize efficiency and profitability.
