Abstract: A method and system (10) for reducing errors in a vehicle manufacturing process is provided. The system is a non-segmented network that includes a plurality of servers (30, 40, 46, 48) for storing build data and transmitting the data to a tracking controller (20). The tracking controller (20) identifies the assembly (18) entering a manufacturing zone (14) and generates positioning information related to the assembly as it passes through the zone (14). The tracking controller (20) is electronically coupled to a series of local I/O interfaces (32) for transmitting the identity, the position information, and the build data of the assembly (18) thereto. Each local I/O interface (32) has one or more I/O manufacturing tools (34, 36) coupled thereto for allowing an operator to perform an assembly task pursuant to the build data. In addition, the I/O manufacturing tools (34, 36) detect whether a successful build condition or an unsuccessful build condition results from performance of the assembly task.
