PLM is a comprehensive approach to managing the entire lifecycle of a product, from ideation to retirement. PLM involves managing data, processes and people across multiple departments and functions, including product design, development, manufacturing and support.
Control design is the process of designing control systems that monitor and control processes, machines and other systems. Control design involves choosing and implementing appropriate control algorithms and hardware components to ensure that the process operates within desired limits. Control design can be integrated into a PLM process.
