Supplier capability

Where you have required your subcontractors to send a certificate of conformity (CofC) testifying the consignment s conformity with the order, you cannot omit all receiving checks. Once supplier capability has been verified, the C of C allows you to reduce the frequency of incoming checks but not to eliminate them. The C of C should be supported with test results. Therefore you need to impose this requirement in your purchasing documents. However, take care to specify exactly what test results you require and in what format you require them presented, as you could be provided with attribute data when you really want variables data. 

When purchasing system software, standard instruments, microcontrollers, smart instruments, and standard software packages, it is the practice of organizations to initially rely on the history of the supplier and the industry operating experience as assurance of the supplier capability of program performance suitability. 

The CSSX process utilizes a novel solvent made up of four components calix[4]arene-bis-(4-fer/-octylbenzo-crown-6) known as BOBCalixC6 as extractant a lipophilic fluorinated alcohol, l-(2,2,3,3-tetrafluoropropoxy)-3-(4-. ec-butylphenoxy)-2-propanol known as Cs-7SB, as diluent modifier tri- -octylamine as a suppressor of impurity effects and the isoparaffinic diluent Isopar L, a mixture of branched hydrocarbons with an average chain-length of 12 carbons. Figure 3 shows the composition of the solvent as currently optimized for the SWPF application at the SRS [37,49], The chemistry of the solvent is well understood, with regards to both its fundamental properties and its performance under process conditions. All of the components are commercially available, and efficient synthetic and purification procedures have been worked out [17,18,37], Thus, these key components may be obtained from multiple chemical suppliers capable of specialty synthesis. 

A Supplier Audit is an opportunity to establish good working relationships among the likely project team. A collaborative conduct of an audit can greatly facilitate project strategy through a realistic, constructive assessment of capabilities, reducing overall project risk. An independent assessment provides objective review of the supplier capabilities.

Understand need for surveillance/monitoring of supplier capability, possibly part of a partnership relationship, and avoid repeat use of a supplier who does not deliver required compliance. 

This strategy involves shrinking the supply chain as products and even businesses are removed. Cousideratiou of the suppliers capabilities has to happen so that the supplier is able to remaiu iu busiuess. If this situatiou is handled poorly, a supplier for mauy differeut materials may be lost. A company s main or critical products ueed to be protected by healthy suppliers. 

Core buyers and their management of the buyer-supplier relationships for product specification and production at Ford Motor Company are described in [51]. Ford has over 350 core buyers responsible for overseeing the relationship with approximately 1,150 suppliers. These suppliers provide component parts or systems (e.g., brake pedals, seats, car audio systems), which are, in turn, assembled into Ford s cars. The core buyers evaluate supplier capability negotiate component specifications, prices, and quantities and decide if suppliers should be offered engineering assistance. While no costs are charged to supphers, the procurement manager chooses how to deploy these scarce resources to dehver benefits to Ford. 

The key issue to be managed in such contracts is the agency effect, as described in the earlier section. The agency effect reflects the fact that only the agent (the supplier) knows the true quality, while the principal (the buyer) experiences the cost of the quality. The associated problem then is similar to the unknown supplier capability discussed in the previous section. Similar to the models discussed there, contracts between the buyer and the supplier can include buyer oversight and buyer-recommended processes that involve buyer costs but may affect supplier costs as well. The optimal contract thus has to account for the extent of buyer oversight and its associated impact on the information rents that have to be paid to suppliers. 

The supplier will choose the optimal lot size x that minimizes his costs. Thus the corresponding supplier cost would be /2DhK xi,product specifications and supplier capability. In addition, suppose that the cost of each step depends on suppliet capability, s 4>), i.e., K x, 4>) = N x, 4>) X s 4>). 

However, if the suppliers capability influences both the cost of each step and the number of steps, it is possible to generate a substitutes relationship, which allows the supplier cost to improve more for a less capable supplier than for a more capable supplier. Figure 3.2 shows that as the buyer involvement increases, the supplier capability impact on costs becomes less steep. In other words, supplier assistance helps the buyer decrease information-related costs. 

Given the description above, buyers would tend to provide more assistance in a substitutes relationship than in a complements relationship. This is the result in [51]. The example above su ests that buyers should consider the tradeoff between involvement with the supplier and its impact on the information rent, i.e., the difference in cost performance across suppliers with different capabilities. If buyer involvement flattens the cost curve across suppliers, that is, decreases cost differences across supplier capabilities, the relationship is one of substitutes, and it may...

To reduce the damage caused by the capacity constraints of the suppliers, buying companies can assist by upgrading suppliers technical capabilities and fostering continuous improvement programmes. They can also invite the suppliers to their plant to see how their items are used and include suppliers into their new product development processes, which enables suppliers to have a better understanding of manufacturing and thus better coordinate operations. As a result, suppliers capability and performance is improved, operations of the two companies are better coordinated, the continuity of supply is ensured and supply risk is reduced.

It follows that the two factors - supplier s capability and the interface between the supplier and the buyer -determine the supply chain effectiveness. The interface governs the relationships between the supplier and the buyer, and helps operationalize the business models of collaboration. The supplier and buyer must be able to formalize such collaboration by leveraging the individual supplier capabilities. Clearly, the buyer would be effective if s/he can build a dynamic supply network that is responsive to the needs of consumers, including rapid fulfillment of orders. The buyer may also need expertise to manage relationships with offshore suppliers.
