Group Technology (GT)
(A.k.a. Part Families) Group Technology separates parts into “Families” or groups that have similar needs with respect to manufacturing processes. Parts may be “grouped” by size weight, color, flavor, chemistry, treatments/special processing needed, etc.
Comments: Creating “Part Families” or “Groups” can result in lower inventories, reduced consumption of process resources, and many other benefits.
On an intuitive level and for the purpose of identifying and exposing your “Value Stream” grouping parts into “families” can help to identify further improvement opportunities.
