It defines legacy systems as large, critical software systems that are difficult to modify efficiently due to lack of documentation. It lists some modernization approaches like IRP, APS, and PDIO and notes benefits of modernization like improved decision making, productivity, and planning while reducing stock levels and ensuring accurate information.
