供应链管理及业务管理知识分析模式(英文版) Supply Chain Management and Business Management Knowledge Analysis ModelIntroduction:Supply chain management (SCM) and business management are two crucial aspects of a company's success and growth. SCM involves the coordination and management of all activities involved in buying, producing, and delivering products or services to customers. On the other hand, business management encompasses the planning, organizing, and controlling of all business operations to achieve organizational goals. This article aims to analyze the key knowledge areas within SCM and business management, highlighting their importance and interdependence.1. Supply Chain Management Knowledge Areas:1.1 Logistics Management:Logistics management focuses on the movement of goods and materials from suppliers to customers. It involves the transportation, warehousing, inventory control, and order fulfillment processes. Efficient logistics management ensures timely delivery, reduces costs, and enhances customer satisfaction.1.2 Procurement and Supplier Management:This knowledge area involves the selection, evaluation, and management of suppliers to ensure the reliable and cost-effective supply of materials or services. It includes activities such as sourcing, negotiation, contract management, and supplierperformance measurement.1.3 Demand Planning and Forecasting:Demand planning and forecasting involve the estimation of future customer demand for products or services. It helps in the optimization of inventory levels, production planning, and resource allocation. Accurate forecasting reduces stockouts, minimizes inventory carrying costs, and improves customer service.1.4 Inventory Management:Inventory management encompasses the control and optimization of inventory levels to meet customer demands while minimizing holding costs. It includes inventory classification, safety stock determination, replenishment strategies, and utilization of advanced inventory management techniques like just-in-time (JIT) and economic order quantity (EOQ).1.5 Risk Management:Supply chain risk management involves identifying, assessing, and mitigating risks associated with supply chain operations. It includes evaluating risks related to supplier reliability, demand volatility, transportation disruptions, natural disasters, and geopolitical factors. Effective risk management helps in minimizing potential disruptions and ensuring business continuity.2. Business Management Knowledge Areas:2.1 Strategic Planning:Strategic planning involves setting the long-term goals and direction of the company. It includes analyzing internal andexternal factors, conducting market research, defining the company's mission and vision, and formulating strategies to achieve competitive advantage. Strategic planning provides a roadmap for decision-making and resource allocation.2.2 Financial Management:Financial management focuses on the efficient utilization and allocation of financial resources within the company. It includes budgeting, financial analysis, cash flow management, and capital investment decisions. Effective financial management ensures profitability, liquidity, and sustainability of the business.2.3 Organizational Behavior:Organizational behavior refers to understanding individual and group dynamics within the company. It includes topics like motivation, leadership, communication, team dynamics, and organizational culture. Understanding and managing organizational behavior promotes employee engagement, productivity, and effective teamwork.2.4 Marketing and Sales Management:Marketing and sales management involves the identification of target markets, development of marketing strategies, and implementation of promotional activities to achieve sales objectives. It includes market research, product development, pricing, distribution, and customer relationship management. Effective marketing and sales management drive customer acquisition, retention, and revenue generation.2.5 Operations Management:Operations management focuses on the design, control, and improvement of production processes to deliver products or services efficiently. It includes capacity planning, production scheduling, quality management, and continuous process improvement. Effective operations management increases productivity, reduces costs, and ensures customer satisfaction.Conclusion:Supply chain management and business management are interconnected and essential for the success of any company. A comprehensive knowledge analysis model helps to identify and prioritize key knowledge areas within these domains. Companies that effectively manage their supply chains and employ sound business management principles gain a competitive edge, achieve operational excellence, and sustain long-term growth and profitability.3. Interdependence between Supply Chain Management and Business Management:The interdependence between supply chain management and business management is crucial for the overall success and growth of a company. While supply chain management focuses on the operational aspects of sourcing, production, and delivery, business management provides the strategic framework and direction for these activities. The knowledge areas within both domains are interconnected and rely on each other for effective decision-making and implementation.For example, strategic planning plays a significant role in both supply chain management and business management. A company'sstrategic objectives and goals influence its supply chain strategy, such as sourcing strategies, selection of suppliers, and distribution network design. On the other hand, the company's supply chain capabilities and constraints impact its overall strategic decisions, such as market entry strategies, product differentiation, and pricing.Similarly, financial management is essential for both supply chain management and business management. Efficient financial management helps in allocating resources effectively within the supply chain, such as optimizing inventory levels, implementing cost-saving measures, and improving cash flow. It also enables the company to make informed business decisions, such as investing in new technologies or expanding into new markets.Organizational behavior plays a critical role in both domains as well. Effective communication, teamwork, and leadership within the supply chain contribute to smooth coordination and collaboration among various stakeholders. In business management, understanding organizational behavior helps in creating a positive work culture, motivating employees, and fostering innovation, thereby leading to better business performance and customer satisfaction.Marketing and sales management are interconnected with supply chain management as well. Market research and customer insights are crucial in demand planning and forecasting, which informs supply chain decisions, such as production levels, inventory management, and transportation requirements. Conversely, supply chain capabilities influence marketing and sales strategies, such as product availability, delivery speed, and customer service levels.Integration between these knowledge areas ensures alignment between supply and demand, resulting in customer satisfaction and competitive advantage.Furthermore, operations management plays a key role in both supply chain management and business management. Efficient operations management techniques, such as lean manufacturing, Six Sigma, and total quality management, improve productivity, reduce waste, and enhance product/service quality. These improvements, in turn, enhance the company's overall performance and competitiveness. Additionally, operations management principles help in optimizing supply chain processes, such as production scheduling, inventory management, and order fulfillment, leading to cost savings, shorter lead times, and improved customer satisfaction.4. Importance of Supply Chain Management and Business Management Knowledge:The knowledge areas within supply chain management and business management are crucial for companies to remain competitive, adapt to changing market dynamics, and drive overall business success. Below are the key reasons why companies should prioritize and invest in these knowledge areas:4.1 Optimal Resource Utilization:Efficient supply chain management ensures optimal utilization of resources, such as raw materials, production capacity, and transportation, resulting in cost savings and improved profitability. Likewise, effective business management helps in allocatingfinancial, human, and technological resources to their best possible use, maximizing the value generated by the company.4.2 Enhanced Customer Satisfaction:Supply chain management focuses on meeting customer demands by ensuring the availability of products/services, on-time delivery, and quick response to customer queries. This improves customer satisfaction and loyalty. Business management, meanwhile, helps in developing effective marketing and sales strategies, understanding customer preferences, and delivering superior customer service, further enhancing customer satisfaction and building long-term relationships.4.3 Risk Mitigation and Resilience:Supply chain management knowledge areas, such as risk management and procurement, help in identifying and mitigating potential risks to the supply chain, including disruptions from suppliers, transportation issues, or natural disasters. Business management complements these efforts by implementing suitable risk management strategies at the organizational level, such as diversifying revenue streams, implementing robust financial controls, and building strong relationships with key stakeholders. This ensures business continuity and resilience.4.4 Competitive Advantage:Companies that excel in supply chain management gain a competitive advantage by offering better value to customers through lower costs, higher product quality, and faster delivery. Similarly, effective business management, through strategic planning, marketing, and operations, helps companies differentiatethemselves from competitors and create unique value propositions that attract and retain customers.4.5 Innovation and Agility:Both supply chain management and business management knowledge areas foster innovation and agility within organizations. Supply chain innovation, such as implementing advanced technologies like automation, AI, and IoT, improves operational efficiency, reduces costs, and enables faster response to market changes. Business management knowledge areas, such as strategic planning and organizational behavior, help in creating a culture of innovation, driving continuous improvement, and fostering agile decision-making.Conclusion:Effective supply chain management and business management are critical for the success of any company. The knowledge areas within these domains are interconnected and mutually dependent. Companies that prioritize and invest in these knowledge areas gain a competitive edge, achieve operational excellence, and sustain long-term growth and profitability. Understanding and implementing the key principles and practices within supply chain management and business management enable companies to optimize resources, enhance customer satisfaction, mitigate risks, and leverage opportunities for innovation and competitive advantage.。
A supply chain consists of all parties involved, directly or indirectly, in fulfilling a customer request. The supply chain includes not only the manufacturer and suppliers, but also transporters, warehouses, retailers, and even customers themselves. Within each organization, such as a manufacturer, the supply chain includes all functions involved in receiving and filling a customer request. These functions include, but are not limited to, new product, development, marketing, operations, distribution, finance, and customer service.Consider a customer walking into a Wal-Mart store to purchase detergent. The supply chain begins with the customer and his or her need for detergent. The next stage of this supply chain is the Wal-Mart retail store that the customer visits. Wal-Mart stocks its shelves using inventory that may have been supplied from a finished-goodswarehouse or a distributor using trucks supplied by a third party. The distributor in turn is stocked by the manufacturer (say, Procter &Gamble [P&G] in this case). The P&G manufacturing plant receives raw material from a variety of suppliers, who may themselves have been supplied by lower-tier suppliers. For example, packaging material may come from Pactiv Corporation (formerly Tenneco Packaging) while Pactiv receives raw materials to manufacture the packaging from other suppliers. This supply chain is illustrated in Figure 1—1, with the arrows corresponding to the direction of physical product flow.A supply chain is dynamic and involves the constant flow of information, product, and funds between different stages. In our example, Wal-Mart provides the product, as well as pricing and availability information, to the customer. The customer transfers funds to Wal-Mart. Wal-Mart conveys point-of-sales data as well as replenishment orders to the warehouse or distributor, who transfers the replenishment order via trucks back to the store. Wal-Mart transfers funds to the distributor after the replenishment. The distributor also provides pricing information and sends delivery schedules to Wal-Mart. Wal-Mart may send back packaging material to be recycled. Similar information, material, and fund flows take place across the entire supply chain.In another example, when a customer makes a purchase online from Dell Computer, the supply chain includes, among others, the customer, Dell's Web site, the Dell assembly plant, and all of Dell's suppliers and their suppliers. The Web site provides the customer with information regarding pricing, product variety, and product availability. Having made a product choice, the customer enters the order information and pays for the product. The customer may later return to the Web site to check the status of the order. Stages further up the supply chain use customer order information to fill the request. That process involves an additional flow of information, product, and funds among various stages of the supply chain.These examples illustrate that the customer is an integral part of the supply chain. In fact, the primary purpose of any supply chain is to satisfy customer needs and, in the process, generate profit for itself. The term supply chain conjures up images of product or supply moving from suppliers to manufacturers to distributors to retailers to customers along a chain. This is certainly part of the supply chain, but it is also important to visualize information, funds, and product flows along both directions of this chain. The term supply chain may also imply that only one player is involved at each stage. In reality, a manufacturer may receive material from several suppliers and then supply several distributors. Thus, most supply chains are actually networks. It may be more accurate to use the term supply network or supply web to describe the structure of most supply chains, as shown in Figure 1-2.A typical supply chain may involve a variety of stages, including the following: Customers, Retailers, Wholesalers/distributors, Manufacturers, Component/raw material suppliersEach stage in a supply chain is connected through the flow of products, information, and funds. These flows often occur in both directions and may be managed by one of the stages or an intermediary.Each stage in Figure 1-2 need not be present in a supply chain. As discussed in Chapter 4, the appropriate design of the supply chain depends on both the customer's needs and the roles played by the stages involved. For example, Dell has two supply chain structures that it uses to serve its customers.For its corporate clients and also some individuals who want a customized personal computer (PC), Dell builds to order; that is, a customer order initiates manufacturing at Dell. For these customers, Dell does not have a separate retailer, distributor, or wholesaler in the supply chain. Since 2007, Dell has also sold its PCs through Wal-Mart in the United States and the GOME Group, China's largest electronics retailer. Both Wal-Mart and the GOME Group carry Dell machines in inventory. This supply chain thus contains an extra stage (the retailer) compared to the direct sales model also used by Dell.In the case of other retail stores, the supply chain may also contain a wholesaler or distributor between the store and the manufacturer.The objective of every supply chain should be to maximize the overall value generated. The value (also known as supply chain surplus) a supply chain generates is the difference between what the value of the final product is to the customer and the costs the supply chain incurs in filling the customer's request.Supply Chain Surplus=Customer Value-Supply Chain CostThe value of the final product may vary for each customer and can be estimated by the maximum amount the customer is willing to pay for it. The difference between the value of the product and its price remains with the customer as consumer surplus. The rest of the supply chain surplus becomes supply chain profitability, the difference between the revenue generated from the customer and the overall cost across the supply chain. For example, a customer purchasing a wireless muter from Best Buy pays $60, which represents the revenue the supply chain receives. Customers who purchase the muter clearly value it at or above $60. Thus, part of the supply chain surplus is left with the customer as consumer surplus. The rest stays with the supply chain as profit. Best Buy and other stages of the supply chain incur costs to convey information, produce components, store them, transport them, transfer funds, and so on. The difference between the $60 that the customer paid and the sum of all costs incurred by the supply chain to produce and distribute the muter represents the supply chain profitability.Supply chain profitability is the total profit to be shared across all supply chainstages and intermediaries. The higher the supply chain profitability, the more successful is the supply chain.For most profit-making supply chains, the supply chain surplus will be strongly correlated with profits. Supply chain success should be measured in terms of supply chain profitability and not in terms of the profits at an individual stage. (In subsequent chapters, we see that a focus on profitability at individual stages may lead to a reduction in overall supply chain profits.)A focus on growing the supply chain surplus pushes all members of the supply chain toward growing the size of the overall pie.Having defined the success of a supply chain in terms of supply chain profitability, the next logical step is to look for sources of value, revenue, and cost. For any supply chain, there is only one source of revenue: the customer. The value obtained by a customer purchasing detergent at Wal-Mart depends upon several factors, including the functionality of the detergent, how far the customer has to travel to Wal-Mart, and the likelihood of finding the detergent in stock. The customer is the only one providing positive cash flow for the Wal-Mart supply chain. All other cash flows are simply fund exchanges that occur within the supply chain, given that different stages have different owners. When Wal-Mart pays its supplier, it is taking a portion of the funds the customer provides and passing that money on to the supplier. All flows of information, product, or funds generate costs within the supply chain. Thus, the appropriate management of these flows is a key to supply chain success. Effective supply chain management involves the management of supply chain assets and product, information, and fund flows to maximize total supply chain surplus. A growth in supply chain surplus increases the size of the total pie, allowing contributing members of the supply chain to benefit.In this book, we have a strong focus on analyzing all supply chain decisions in terms of their impact on the supply chain surplus. These decisions and their impact can vary for a wide variety of reasons. For instance, consider the difference in the supply chain structure for fast-moving consumer goods observed in the United States and India. U.S. distributors play a much smaller role in this supply chain compared totheir Indian counterparts. We argue that the difference in supply chain structure can be explained by the impact a distributor has on the supply chain surplus in the two countries.Retailing in the United States is largely consolidated, with large chains buying consumer goods from most manufacturers. This consolidation gives retailers sufficient scale that the introduction of an intermediary such as a distributor does little to reduce costs and may actually increase costs because of an additional transaction. In contrast, India has millions of small retail outlets. The small size of Indian retail outlets limits the amount of inventory they can hold, thus requiring frequent replenishment-an order can be compared with the weekly grocery shopping for a family in the United States. The only way for a manufacturer to keep transportation costs low is to bring full truckloads of product close to the market and then distribute locally using "milk runs" with smaller vehicles. The presence of an intermediary who can receive a full truckload shipment, break bulk, and then make smaller deliveries to the retailers is crucial if transportation costs are to be kept low. Most Indian distributors are one-stop shops, stocking everything from cooking oil to soaps and detergents made by a variety of manufacturers. Besides the convenience provided by one-stop shopping, distributors in India are also able to reduce transportation costs for outbound delivery to the retailer by aggregating products across multiple manufacturers during the delivery runs. Distributors in India also handle collections, because their cost of collection is significantly lower than that of each manufacturer collecting from retailers on its own would be. Thus, the important role of distributors in India can be explained by the growth in supply chain surplus that results from their presence. The supply chain surplus argument implies that as retailing in India begins to consolidate, the role of distributors will diminish.There is a close connection between the design and management of supply chain flows (product, information, and funds) and the success of a supply chain. Wal-Mart, Amazon, and Seven-Eleven Japan are examples of companies that have built their success on superior design, planning, and operation of their supply chain. In contrast, the failure of many online businesses such as Webvan can be attributed to weaknessesin their supply chain design and planning. The rise and subsequent fall of the bookstore chain Borders illustrates how a failure to adapt its supply chain to a changing environment and customer expectations hurt its performance. Dell Computer is another example of a company that had to revise its supply chain design in response to changing technology and customer needs. We discuss these examples later in this section.Wal-Mart has been a leader at using supply chain design, planning, and operation to achieve success. From its beginning, the company invested heavily in transportation and information infrastructure to facilitate the effective flow of goods and information. Wal-Mart designed its supply chain with clusters of stores around distribution centers to facilitate frequent replenishment at its retail stores in a cost-effective manner. Frequent replenishment allows stores to match supply and demand more effectively than the competition. Wal-Mart has been a leader in sharing information and collaborating with suppliers to bring down costs and improve product availability. The results are impressive. In its 2010 annual report, the company reported a net income of more than $14.3 billion on revenues of about $408 billion. These are dramatic results for a company that reached annual sales of only $1 billion in 1980. The growth in sales represents an annual compounded growth rate of more than 20 percent.。

It shall describe the general nature of the system and software; summarize the history of system development, operation, and maintenance; identify the project sponsor, acquirer, user, developer, and support agencies; identify current and planned operating sites; and list other relevant documents.]1.3 Document Overview[This paragraph shall summarize the purpose and contents of this document and shall describe any security or privacy considerations associated with its use.]2 Referenced Documents[This section shall list the number, title, revision, and date of all documents referenced in this specification. This section shall also identify the source for all documents.]3 Requirements Summary[This section shall be divided into the following paragraphs to describe the risk management requirements as it currently exists.]3.1 Background, Objectives, and Scope[This paragraph shall describe the background, mission or objectives, and scope of the product or situation.][Example: Requirements regarding software configuration management (SCM) cover a broad arena. SCM is considered one of the integral processes that support the other activities in the standard. The developer's approach, described in the project's SDP, is to address all applicable contract clauses for SCM including:Configuration identificationConfiguration controlConfiguration status accountingConfiguration auditsPackaging, storage, handling, and delivery3.2 Operational Policies and Constraints[This paragraph shall describe any operational policies and constraints that apply to the current system or situation.][Example: SCM activities apply to all software products prepared, modified, and/or used to develop software products as well as to the products under development, modification, reengineering, or reuse. If a system/subsystem or SWI is developed in multiple builds, SCM in each build is to be understood to take place in the context of the software products and controls in place at the start of the build.]3.3 Description of Current System or Situation[This paragraph shall provide a description of the current system or situation, identifying differences associated with different states or modes of operation (for example, regular, maintenance, training, degraded, emergency, alternative-site, wartime, peacetime). The distinction between states and modes is arbitrary. A system may be described in terms of states only, modes only, states within modes, modes within states, or any other scheme that is useful. If the system operates without states or modes, this paragraph shall so state, without the need to create artificial distinctions. ]3.4 Users or Involved Personnel[This paragraph shall describe the types of users of the system, or personnel involved in the current situation, including, as applicable, organizational structures, training/skills, responsibilities, activities, and interactions with one another.][Example: Developer's key activities related to Software configuration management:Describe the approach to be followed for software configuration management, identifying risks/uncertainties and plans for dealing with them. Cover all contractual clauses pertaining to software configuration management.Participate in selecting CSCIs during system (architectural) design. Identify entities to be placed under configuration control. Assign a project-unique identifier to each SWI and each additional entity to be placed under configuration control, including software products to be developed or used and the elements of the software development environment. Use an identification scheme that identifies entities at the level of control and include version/revision/release status.Establish and implement procedures designating levels of control each identified entity must pass through, the persons or groups with authority to authorize changes and to make changes at each level, and the steps tobe followed to request authorization for changes, process change requests, track changes, distribute changes, and maintain past versions. Propose to the acquirer, in accordance with contractually established forms and procedures, changes that affect an entity already under acquirer control. Prepare and maintain records of configuration status of all entities that have been placed under project-level or higher configuration control. Maintain configuration status records for the life of the contract. Include, as applicable, version/revision/release, changes since being placed under project-level or higher configuration control, and status of associated problem/change reports.Support acquirer-conducted configuration audits as specified in the contract.Establish and implement procedures for packaging, storage, handling, and delivery of deliverable software products. Maintain master copies of delivered software products for the duration of the contract.Prepare a version description for the system.Meet general requirements and perform integral processes of the standard.]3.4.1 Configuration Requirements[This paragraph describes the configuration management requirements for the project.][Example: SCM requirements task the developer to "keep track of" everything during the course of the development. SCM is an activity, not an organization. SCM may be performed by members of the development team, individuals within a project tasked with that responsibility, a separate organization, or other arrangement suitable for the project.]3.5 Software Configuration Management Criteria[This paragraph describes the software configuration management criteria to be followed during the project.[Example: The standard requires the developer to establish levels of control for all work products. Some examples of possible levels of control and of things the developer might identify and control are:Author control:Engineering data -- notes, records, work-in-progress (i.e., dataspecified in documents associated with particular developmentactivities)Software development filesProject control:Source code files, data files, installation softwareInformation in documents agreed upon by the project to becorrectReuse librariesEvaluation recordsOrganizational control:General purpose software -- operating systems, databasemanagement systems, e-mail, word processors, spreadsheetsEngineering and development tools -- CASE tools, editors,compilers, debuggers, SCM tools, test softwareComputer system administrative tools and products -- diagnosticsoftware, network managers, archives, backupsEvaluation recordsAcquirer control:SpecificationsSome key goals of SCM requirements are to ensure that the developer: keeps track of all software and software product descriptions associatedwith the project; implements only authorized changes to requirements; and knows what software and associated products match a specific set of requirements or changes to those requirements.To implement changes to requirements, the acquirer and developer must agree upon what those changes are. When requirements have been defined and recorded as specifications and those specifications have been placed on contract, changes are implemented through contract modifications. When specifications have not been made a part of the contract, the acquirer and developer will need to provide a means for controlling and making changes to requirements. These means can be as informal as a phone call or hand-shake, or as formal as documents signed by authorized acquirer and developer representatives. The standard does not provide contractual forms or notices concerning changes in requirements, such as Engineering Change Proposals (ECPs), Engineering Change Notices (ECNs), or notification to users of changes in a particular version of the software. Although the standard does provide a reminder in the form of two "shell" requirements to support acquirer configuration management activities for (1) proposing changes to acquirer controlled entities, and (2) supporting configuration audits, these activities may not apply to all projects.All work products (including computerized files, the software products that constitute the development environment, and hardware), not just deliverables, are to be identified and controlled during the developmentand under developer software configuration management activity. The physically controlled items can include: computer files, magnetic media (tapes, diskettes, video cassettes), paper documents, books, manuals, and drawings.The standard leaves it up to the developer to describe what software configuration management records will be produced, when they will be produced, the level of detail of information that will be contained in each record and who is responsible for performing these activities.4 Justification[This section shall be divided into the following paragraphs.]4.1 Assumptions and Constraints[This paragraph shall identify any assumptions and constraints applicable to the changes identified in this section.]4.2 Additional Items for consideration:[This paragraph shall identify additional items that should be taken into consideration.][Example: Additional items that should be taken into consideration are: Describe the approach to be followed for software product evaluation, identifying risks/uncertainties and plans for dealingwith them. Cover all contractual clauses pertaining to softwareproduct evaluation.•Perform in-process evaluations of the software products generated. Perform a final evaluation of each deliverablesoftware product before its delivery.•Prepare and maintain records of each software product evaluation. Maintain these records for the life of the contract.Handle problems in software products under project-level orhigher configuration control in accordance with paragraph 5.17of the standard.•Maintain independence in software product evaluation. The persons responsible for evaluating a software product are not tobe the same persons who developed the product.•Meet general requirements and perform integral processes of the standard.5 Notes[This section shall contain any general information that aids in understanding this document (e.g., background information, glossary, rationale). This section shall include an alphabetical listing of all acronyms, abbreviations, and their meanings as used in this document and a list of terms and definitions needed to understand this document.]。
