In Torreon, MX., there is a cluster devoted to producing denim garments. There are a number of brand name and contract sewing factories. Over time, the following support groups moved in to take advantage of this business:

a) Trim* suppliers (*in a garment, trim is any component that is not the shell fabric, example: Thread, pocketing, buttons, rivets, zippers and so on).

b) Fabric suppliers - Warehouses carrying denim from other mills, new mills weaving fabric to sell to the manufacturers.

c) Maintenance - sewing equipment sales and services, machine parts, factory maintenance (boiler inspection and repair, vacuum pump service, lift machine sales and service).

Using the list of International Logistics Managers' responsibilities on page 3 of the textbook as your guide, complete the formation of this cluster by creating companies you believe are most needed. Please create 3 support groups and briefly explain their need and contribution to the cluster.
