Group technology is an approach to organizing manufacturing which can be applied in any industry where a small batch variety production is used. The basic concept of group technology (GT) is relatively simple. It is the identification and bringing together related or similar parts and processed, to make advantage of the similarities which exist, during all stages of design and manufacture.

GT is based on the fact that small lots of different parts can be produced more economically, if they are grouped and scheduled for production according to the common characteristics.
