The contract review activities, interfaces, and communication within the supplier s organization are coordinated with the purchaser s (clients) organization, as appropriate. 

If the proper coordination mechanisms are not in place across the various functions, the process will be neither effective or efficient. Taking a process focus means that all functions that touch the product or provide information must work together. For example, purchasing depends on sales/ marketing data fed through a production schedule that are used to assess specific order levels and timing of requirements. These orders drive production requirements, which in turn are transmitted upstream to suppliers. 

An assembly structure is one in which products from separate suppliers or plants are combined to form subassemblies, which in turn are combined to form the final assembly. Figure 2.1 shows a sample assembly supply chain. Automobile industry manufacturers, such as Toyota, Honda, and Ford, all use tiered purchasing arrangements, in which subassemblies from one set of suppliers are combined at the next level until the final car assembly, thus generating an assembly structure of suppliers. In such structures, the complete kit of parts from all suppliers is necessary to complete assembly. Thus, a key task for the operation of an assembly structure is coordinating the deliveries from all suppliers to produce a unit of a finished product. 

The ideal location for product within the Walmart supply chain is the store, where goods can be purchased by customers, rather than in a warehouse. Over 100,000 suppliers, many of whom deliver daily, coordinate with DCs to keep product moving all the way to the store. Product brought into the Walmart DC is usually crossdocked and shipped out within 48 hours. Therefore the supply chain facilities are viewed as conduits for product flow rather than as storage units. By providing central buyers with the flexibility to adjust orders, crossdocking at Walmart can operate efficiently. Loads to stores can be optimized and balanced with... 

The specific purchasing decisions include the make-buy decision for components and products, global location of sources for manufacturing and distribution facilities, and coordination with suppliers to maximize mutual benefit. 

Since supplier employees play a coordinating role, the corresponding buyer purchasing agent can be eliminated. Thus, Bose replaced a market ... 

The main difference under consignment inventory is that the manufacturer continues to own the retail consignment inventory until the product is sold to the customer. Thus, consignment inventory is equivalent to the manufacturer purchasing store shelf space and choosing inventory levels to maximize his profits. Coordination is achieved because the supply chain decisions are made by one decision maker. Such an approach is common in the provision of spices the spice racks in many retail stores are managed by the supplier. 

Next, each supplier submits the process control plan described earlier to the supplier. The QOS and process control plan allow the purchaser to conduct a quality audit. If there were any unacceptable findings during the audit, the purchasing firm requires the supplier to submit a corrective action plan that identifies what actions the supplier will take to contain and then eliminate the defect, the coordinator of the plan, and the expected completion date of the correction. The purchasing firm follows up on the supplier s progress through phone contacts with the action plan coordinator and through data submitted by the coordinator. 

Once they had designed their dream bikes, customers would pay with a credit card, and the distributor would immediately be informed of what components to place in a kit. The kit was shipped to ABC, where it was joined by the frame and the entire knocked-down kit was shipped to the partner in Mexico, who had already scheduled the assembly of the bike and been partially paid for it (sales transaction mth the end-user, transaction with ABC s customer— the custom bike maker, or the Mexican bike assembler, transaction with the distributor and the supplier to the distributor— all initiated by one customer purchase, but carried out and coordinated by E-commerce). 

At the strategic level, firms need to decide whether they should have longterm contracts with a few fixed suppliers or utilize auctions and a dynamic supplier base to reduce their costs. In particular, firms need to understand under what circumstances is it beneficial to have (1) long term relationships (2) auction based short term relationships or (3) a combination of (1) and (2). Another important decision is whether a firm should have one supplier or multiple suppliers and how that choice may depend on repetition in purchase. In the following sections, we discuss papers that study - (1) coordination of traditional and internet procurement (2) formation of electronic consortia and their impact on procurement strategies. 

To demonstrate the feasibility of virtual model creation, it was used part of a cow femur bone once it was easily purchased from a specialist supplier. The selected part allowed about 288 tomography cuts to be taken by a helicoidally tomography scan machine from General Electric Medical Systems, model HiSpeed CT. The cut analysis interval started at the CUT 100 and finished at the CUT 140. The procedures to obtain the cloud of points were (a) removal of unwanted lines and imperfections due to the bone porosity (b) removal of the internal edge (c) edge detection techniques (d) image preparation for Cartesian coordinate s acquisition and (e) the acquisition of the Cartesian coordinates. 

Visibility is focused on resources and, in particular, inventories (inventory visibility). This means that resources are visible in the supply chain and can be noticed from any link, thus making it possible to monitor the inventory level in the entire supply chain. Velocity means the capacity to meet needs (fulfilment velocity) or fulfil a contract in a short time. Versatility consists in the capacity to collaborate with suppliers and purchasers when faced with various terms of delivery (coordination versatility). These are the three pillars of adaptive supply chains. According to Ivanov, Sokolov and Kaeschel (2010, p. 411), a supply chain may be called adaptive if it can adapt to ... 

If the processes in a supply chain are not coordinated, they impact multiple companies negatively. It may lead to activities being replicated, inconsistent flows, and erroneous decisions. It may take a great deal of effort to manage the cumbersome interactions between companies. For example, HP s supply chain for computer monitor comprised a contract manufacturer (Solectron), who bought the plastic case for the monitor from an injection molder, shown in Fig. 3.7 (Hammer 2001). The molding-material was purchased from a plastics compounder, who acquired the resin (for compounding) from a resin supplier. The supply chain was linear and hierarchical, with the resin supplier upstream, HP downstream, and the rest in-between. 

For example, the principal supplier of injection moulding components coordinated purchase and delivery of plastic parts from the other smaller suppliers, which had formerly all been tier 1. The before and after scenarios are shown in Figure 2.12.
