A "Lineside" System refers to an aftermarket system or process that was not part of the Original Equipment Manufacturer (OEM) production line or equipment.
These systems are fitted to existing production equipment specifically to measure, monitor and analyze the performance of the production line or machine. They utilise data acquisition hardware, machine interface, and some form of analysis software to gather and analyse operational data. This data analysis is then used to implement and monitor machine changes to improve production efficiency or quality on that line, using the Six Sigma approach.
