Purchase Modern enterprises are faced with diverse and individualized needs of the dual challenges that require materials procurement and supply chain to meet the production process of the Flexible Materials (diversity) and rigid (quality) requirements. For manufacturing enterprises, for the sales and production, for the production and procurement is an interlocking material input and output dynamic process, in turn constitute the procurement process, production processes and sales process. From the logistics point of view, the initial success of the procurement process to run will directly affect the production and sale of the final product pricing and ultimately the entire supply chain profitability. Business procurement process &quot;leading role&quot; can not be ignored. Today, however, many companies are not scientific procurement process, procurement mechanism is not quite reasonable, is not conducive to the production and sale of IT technologies must be addressed. ?Inadequate information and procurement model is the enterprise behind the fundamental problem in the procurement ?As the structure, mechanism, so the reason, the traditional Purchase in many incompatible with the requirements of modern procurement areas affecting the efficiency and effectiveness of procurement, include: ?Information can not be shared. Since the privatization of information between organizations without the integration of effective procurement information is not shared, including among purchaser and suppliers, corporate purchasing department and related departments, as well as between managers and implementers. ?Adopted for the two sides did not establish a stable cooperative relationship. This is caused by the old procurement model, they are a temporary or short-term oriented cooperation mechanism, resulting in competition rather than cooperation, which led to the uncertainty of the procurement process. Demand planning and forecasting and materials combined, and do not need that can not be effectively organized according to the production procurement, supply planning and realization of material balance of the current demand and inventory investment and business and Celue consistent. Can not track purchases, including the processing of requisitions, purchase order processing, quotation processing inquiry; transport processing, receipt processing, quality control. Lack of constraints (procurement services authorized issuance, approval, implementation and there is no record of job classification), prone to black-box operation. Lack of supplier evaluation and management. In short, because they do not clear the information and behind the procurement model, changes in market demand, the purchaser can not change the supply side has been provided to the procurement contracts, the ability of companies slow to respond to user needs. Cooperative purchasing - an effective model to solve the procurement problem The traditional procurement model can not meet the requirements of modern enterprises must use the new procurement model - Replaced by collaborative procurement. This new procurement model to supply chain management strategy, improved relationships with suppliers, emphasizing the concept of synergy, and, with the purchase of variety, quantity and frequency increases, the coordination role will become more apparent, including: ?Internal collaboration ?Enterprises to implement effective procurement action requires internal coordination with the various business units, including the design and development department, production department, sales department, finance departments, and timely maintenance of data, such as materials, vendors, purchase prices, etc. the only way to purchase at reasonable prices to the required materials, appropriate and implement the correct delivery amount. Enterprise and external collaboration ?Purchase not only the synergy within the enterprise, but also need external cooperation, namely with suppliers in the inventory, demand and other aspects of information sharing. Enterprise can adjust the supply of the supply chain planning and execution process. Meanwhile, suppliers can stock business, plans and other information to adjust supply. From a &quot;for the stock purchase&quot; to &quot;purchase order&quot; of transform In supply chain management conditions, order-driven activities Caigou way, such methods can be time customer of Xu Qiu Xiang Ying, lower inventory costs, Jin Er changed its traditional inventory Buchong Wei Mu De buying patterns. ?Strengthen the management of external resources Effective management of external resources can create a new and different levels of supply network to reduce the number of suppliers, and suppliers to establish a long-term, mutually beneficial relationship, and then abandon the traditional procurement management deficiencies: lack of cooperation, lack of flexibility and rapid response capacity on demand. IT technology procurement solution provides a powerful tool Effective use of collaborative procurement model to solve the problem of procurement enterprise management, we must rely on the strong technical support. IT technology and advanced management mode (especially ERP), combined with effective solution to the procurement. According to statistics, IT technology can usually get 5% to 40% of the total savings, while the typical range of cost reduction is 15% to 20%. Set smooth procurement process Procurement process for the production needs including supplier selection and purchase of materials involved in the activities of business processes. Smooth and efficient business processes to safeguard the basis for procurement, it should have optimized, non-redundant, parallel operation of the basic properties. ?Build a reasonable structure Good procurement process needs an appropriate institutional structure to support, the organizational structure should be flattened, and support of advanced procurement models, such as centralized purchasing, distributed procurement. The implementation of procurement data management is fast transfer of information, sharing basis. Procurement data include material data, supplier data and purchasing price data. Should establish the uniqueness of the procurement data entry, dynamic updating and maintenance mechanisms. Sound procurement data can quickly find and evaluate suppliers, inquiring, the formation of purchase orders, approving, tracking procurement. Figure 3 is the rapid formation of data using a purchase order procurement process. Integration with related business functions Materials procurement and sales, production, inventory, finance, quality, supply and other closely related business areas, need to be co-related departments. Therefore, data sharing and business integration for the implementation of collaborative procurement model is necessary and essential. Figure 4 shows purchases and sales, materials management, financial integration mechanism. Several IT applications based on good procurement Procurement of IT technology in the enterprise wide application, for the development of new and efficient means of procurement of the possible application of these procurement methods to improve the procurement efficiency and far-reaching effects will play an important role. Centralized purchasing Centralized procurement is relatively decentralized procurement purposes, the procurement organizations to purchase multiple enterprises, this form applies to conglomerates. HP&#39;s use of information technology such as reconstruction of the procurement process, head office and the manufacturers use a common procurement software system, although the sector remains as it has done its own order, but since the use of a unified standard procurement system, to fully grasp the needs of the headquarters situation, and sent Purchasing negotiations with suppliers, the total contracts signed, greatly reducing the cost of procurement. Global Sourcing Global sourcing is more geographically expanded the scope of centralized procurement, it broke and played down the time and space constraints, to achieve a cross between the inquiry, quotation, sample delivery, orders issued, Customs and other operations reporting, business in the world for raw materials and components within the source. This form of inter-enterprise procurement interdependence, interaction and mutual constraints increasingly obvious characteristics of the product meets the requirements of large corporate globalization strategy. ?Online Procurement ?As a specific form of global procurement, online procurement for the procurement staff provides a quick tool to reduce the procurement cost of the system, that is through Internet in real time around the globe to communicate with suppliers and trading. Online purchasing will be buyers and suppliers as &quot;win-win&quot; new forms of procurement, mainly seller system, the buyer system and third party systems three kinds of forms. Procurement time Time procurement is to meet the time production systems (JIT) of 需 要 the formation of that supplier capability &quot;needed the time, the need to place, with reliable quality from production enterprises Tigong necessary materials&quot;.
