SUPPLY CHAIN MANAGEMENT
IMPORTANCE
- Most firms spend a huge portion of their sales on purchases. Since the increasing
percentage of an organization’s cost are determined by purchasing, relationships with
suppliers are increasingly integrated and long term. Combined efforts that improve
innovation, speed design, and reduce costs are common. Such efforts, when part of
a corporate-wide strategy, can improve partner’s competitiveness. This integrated
focus places added emphasis on managing supplier relationships
Supply Chain Management
- Refers to the coordination of all supply chain activities involved in enhancing
customer value
- Describes the coordination of all supply chain activities, starting with raw materials
an ending with a satisfied customer.
- Includes:
o Suppliers
- Manufacturers & service providers
o Distributors
- Wholesalers and retailers
- Delivers the product/service to the final customer
- Objective: to structure the supply chain to maximize its competitive advantage and
benefits to the ultimate consumer.
- Central feature of successful supply chains is members acting in ways that benefit the
team (the supply chain)
SOURCING ISSUES
Make-or-Buy Decisions
- Refers to a choice between producing a component or service-in-house or purchasing
it from an outside source
- Choosing products and services that can be advantageously obtained externally as
opposed to produced internally
- Supply chain personnel evaluate alternative suppliers and provide current, accurate
and complete data relevant to the alternatives
Outsourcing
- Refers to the transferring a firm’s activities that have traditionally been internal to
external suppliers
- Transfers some of what are traditional internal activities and resources of a firm to
outside vendors, making it slightly different from the traditional make-or-buy decision
- Part of the continuing trend toward using the efficiency that comes with
specialization.
6 SOURCING STRATEGIES
Many Suppliers
- Supplier responds to the demands and specifications of “request for quotation” with
the order usually going to the low bidder
- Common strategy for products like commodities
- Plays one supplier against one another and places the burden of meeting the buyer’s
demands on the supplier
- Makes supplier responsible for maintaining the necessary technology, expertise and
forecasting abilities as well as cost, quality and delivery competencies
- Long term partnering relationships are not the goal
Few Suppliers
- Buyer is better off forming a long-term relationship with few dedicated suppliers,
rather than looking for short-term attributes like low cost
- It can create value by allowing suppliers to have economies of scale and a learning
curve that yields both lower transaction costs and lower production costs
- Encourages suppliers to provide design innovations and technological expertise

  • Encourages suppliers to provide design innovations and technological expertise

Vertical Integration

  • Refers to the developing ability to produce goods or services previously purchased or actually buying a supplier or a distributor
  • Another form of vertical integration: forward or backward integration o Suggests that a firm purchase its suppliers o May be particularly dangerous for firms in industries undergoing technological change if management cannot keep abreast of those changes or invent the financial resources necessary for the next wave of technology
  • Offers strategic opportunity for the operations manager
  • For firms with capital, managerial talent and required demand, vertical integration may provide substantial opportunities for cost reduction, higher quality, timely delivery, and inventory reduction.
  • Appears to work best when organization has a large market share and the management talent to operate an acquired vendor successfully
  • May be particularly dangerous for firms in industries undergoing technological change if management cannot keep abreast of those changes or invent the financial resources necessary for the next wave of technology as research and development costs are too high and technology changes are too rapid to sustain for one company to sustain leadership in every component
  • Most organizations are better served concentrating on their own specialty and leveraging suppliers’ contributions

Joint Ventures

  • A strategic partnership where 2 or more companies collaborate to achieve common business objectives while maintaining their individual identities
  • Used to share resources, risks and expertise for sourcing raw materials, manufacturing, logistics and distribution
  • Firms may engage in collaboration to enhance their new product prowess or technological skills, and to secure supply or reduce costs Keiretsu Networks
  • Keiretsu: describes suppliers who become part of a company coalition
  • Manufacturers are often financial supporters of suppliers through ownership or loans
  • Members of keiretsu are assured long-term relationships and are therefore expected to collaborate as partners, providing technical expertise and stable quality production to the manufacturer
  • Members also can have second and even third-tier suppliers as part of coalition Virtual Companies
  • Refers to the companies that rely on a variety of supplier relationships to provide services on demand.
  • Also known as hollow corporations or network companies
  • Rely on variety of good, stable supplier relationships to provide services on demand o includes payrolls, hiring personnel, designing products, providing consulting services, manufacturing components, conducting tests or distributing products
  • may be short term/long term and may include true partners, collaborators or simply able suppliers and subcontractors
  • Advantages: specialized management expertise, low capital investment, flexibility and speed resulting to efficiency SUPPLY CHAIN RISK Risk and Mitigation Tactics
  • Companies need to focus not only on reducing potential disruptions but also on how to prepare for responses to inevitable negative events
  • Flexible, secure supply chains and sufficient insurance against a variety of disruptions are a start
  • Companies may also diversify their supplier base by using multiple sources for critical components
  • Cross-sourcing

o These 3 contribute to distortions of information about what is really occurring in the supply chain

  • Bullwhip Effect o Results from distortions and fluctuations o Refers to increasing fluctuation in orders that often occurs as orders move through the supply chain o Occurs as orders are relayed from retailers, to distributors, to wholesalers, to manufacturers, with fluctuations increasing at each step in the sequence o Increases costs associated with inventory, transportation (may use expensive 3 rd^ party logistic services for rush orders), shipping, and receiving while decreasing customer service and profitability Opportunities in Managing the Integrated Supply ChainAccurate “Pull” Data
  • Accurate sales data that initiate transactions to “pull” product through the supply chain
  • Generated by sharing: ▪ Point-of-sales (POS) information so that each member of the chain can schedule effectively
  • Collect sales data and then adjusting that data for market factors, inventory on hand and outstanding orders ▪ Computer-assisted ordering (CAO)
  • Net order is sent directly to supplier, who is responsible for maintaining the finished goods inventory ➢ Lot Size Reduction
  • Lot size are reduced through aggressive management
  • Includes: ▪ Developing economical shipments of less than truckload lots ▪ Providing discounts based on total annual volume rather than size of individual shipments ▪ Reducing the cost of ordering through techniques such as standing orders and various forms of electronic purchasing ➢ Single-stage control of Replenishment
  • Refers to fixing responsibility for monitoring and managing inventory for the retailer
  • Means designating a member in the chain as responsible for monitoring and managing inventory in the supply chain based on the “pull” from the end user
  • Removes distorted information and multiple forecasts that create bullwhip effect
  • Control may be in the hands of: ▪ Sophisticated retailer who understands demand patterns ▪ Distributor who manages the inventory for a particular distribution area ▪ Manufacturer who has a well-managed forecasting, manufacturing and distribution system ➢ Vendor-managed inventory
  • A system in which a supplier maintains material for the buyer, often delivering directly to the buyer’s using department
  • Means the use of a local supplier (usually a distributor) to maintain inventory for the manufacturer or retailer and deliver directly to purchaser’s using department rather than to a stockroom
  • Supplier takes responsibility for monitoring inventory levels and restocking the buyer’s inventory as needed
  • How it helps: ▪ Prevents stockouts and overstock situations ▪ Reduce administrative costs ▪ Strengthens supplier-buyer relationships ➢ Collaborative Planning, Forecasting and Replenishment (CPFR)
  • A system in which members of a supply chain share information in a joint effort to reduce supply chain costs
  • Members of the supply chain share planning, demand, forecasting, and inventory information
  • Significantly help reduce the bullwhip effect ➢ Blanket orders
  • A long-term purchase commitment to a supplier for items that are to be delivered against short-term releases to ship
  • Unfilled orders with a vendor
  • Also called open orders or incomplete orders
  • A contract to purchase certain items from a vendor
  • Instead of placing separate orders, the buyer and supplier agree on terms, pricing, delivery schedules in advance
  • Enhances supply chain efficiency, cost savings and supplier relationships while ensuring a steady flow of materials

Standardization

  • Rather than obtaining a variety of similar components with labeling, coloring, packaging or different engineering specifications, the purchasing agent should try to have those components standardized
  • Refers to establishing uniform specifications for products, processes or components across multiple stages of supply chain
  • Ex: using same parts across multiple models instead of making unique parts in producing products ➢ Postponement
  • Delaying any modifications or customization to a product as long as possible in the production process
  • Withholds any customization to the product as long as possible
  • Minimize internal variety while maximizing external variety
  • A supply chain strategy where final product assembly, customization or packaging is delayed until the latest possible stage before reaching the customer
  • Allows companies to be more flexible, reduce costs and better respond to customer demand
  • Ex: build-to-order model by Dell that customers can customize their laptop specifications before shipping it to them. This helps them determine what and how much parts are they going to order without producing too much ➢ Electronic Ordering and Funds Transfer
  • Traditional approaches to speeding transactions and reducing paperwork
  • Use of digital systems, online platforms, or automated process to place, track and manage orders between buyers and suppliers
  • Ex: using of RFIDs to track inventory and reorder automatically when inventory is low ➢ Drop Shipping and Special Packaging
  • Drop shipping ▪ Shipping directly from the supplier to the end consumer rather than from the seller, saving both time and reshipping costs
  • Use of special packaging, labels and optimal placement of labels and bar codes on container are part of cost-saving measures

BUILDING THE SUPPLY BASE

  • Suppliers must be selected and actively managed by firm for those goods and services bought from them
  • Supplier selection considers numerous factors including strategic fit, supplier competence, delivery and quality performance
  • Supplier Selection Process:Supplier evaluation - First stage of supplier selection - Involves finding potential suppliers and determining the likelihood of their becoming “good” suppliers - If good suppliers are not selected, then all other supply chain efforts are wasted. Long-term relationships play a vital role as firms move toward long-term suppliers, the issues of financial strength, quality, management, research, technical ability, and potential for close will arise - Supplier Certification o International quality certifications like ISO 9000 and ISO 14000 are designed to provide external verification that a firm follows sound quality management and environmental management standards. o Can be use by buyer as pre-qualification for their potential suppliers o Certification process involves 3 steps: - Qualification - Education - Certification performance process o Once certified, supplier may be awarded special treatment and priority ▪ Supplier development - Buyer makes sure that suppliers has an appreciation of quality requirements, product specifications, schedules and delivery, and procurement policies - May include everything from training, to engineering and production help, to procedures for information transfer
  • Online Auctions o Some suppliers and buyers have established online auction sites o Operation mangers find online auctions a fertile area for disposing excess raw materials and discontinued or excess inventory LOGISTICS MANAGEMENT
  • An approach that seeks efficiency of operations through the integration of all material acquisition, movement and storage activities
  • Involves planning, coordination and execution of moving goods, services and information from suppliers to customers in an efficient and cost-effective manner
  • Ensures that materials, inventory and finished goods reach their destination on time and in good condition Shipping Systems
  • Firms recognize that transportation of goods from and to their facilities can represent as ¼ of the cost of products, thus the means of shipping must constantly evaluate
  • 6 major means of shipping o Trucking
  • Majority of manufactured goods moves by truck
  • Trucking firms are using computers to monitor weather, find the most effective route, reduce fuel cost and analyze the most efficient way to unload o Railroads
  • Cost-effective for large shipments
  • Best for long distances transportation of heavy and bulk cargo o Airfreight
  • Offers speed and reliability
  • Best for urgent, high value items
  • Fast shipping but expensive o Waterways
  • One of the oldest means of freight transportation
  • Usual cargo on internal waterways is bulky, low value cargo
  • Internationally, millions of containers holding all sorts of industrial and consumer goods are shipped at very low cost via huge oceangoing ships
  • Often preferred when cost is more important than speed o Pipelines
  • Important forms of transporting crude oil, natural gas and other petroleum and chemical products
  • Best for continuous transport of liquids/gases o Multimodal
  • Combines various shipping methods for efficiency
  • Common means of getting a product to its final destination, specifically for international shipments Warehousing
  • Fundamental purpose is to store goods
  • Provide other crucial functions: o Consolidation point
  • Gathering shipments from multiple sources to send outbound in one cheaper, fully loaded truck o Break-bulk function
  • Accepting a cheaper full truckload inbound shipment and then dividing it for distribution to individual sites o Cross-docking
  • Accepting shipments from variety of sources and recombining them for distribution to a variety of destinations, without actually storing goods during transition o Postponement
  • Providing final customer specific value-added processing to the product before final shipment
  • Channel assembly
  • Represents one way to implement postponement
  • Postpones final assembly of a product so the distribution channel can assemble it
  • Send individual components and modules, rather than finished products, to the distributor then assemble, tests and ships it
  • Treats distributor as manufacturing partners than a mere distributor

Third-Party Logistics (3PL)

  • Tends to bring added innovation and expertise to the logics system
  • Supply chain managers outsource logistics to meet 3 goals: o Drive down inventory investment o Lower delivery costs o Improve delivery speed and reliability DISTRIBUTION MANAGEMENT
  • Focuses on the outbound flow of products.
  • Designing distribution networks to meet customer expectations suggest three criteria: o Rapid response o Product choice o Service

ETHICS AND SUSTAINABLE SUPPLY CHAIN MANAGEMENT

Supply Chain Management Ethics

  • Three aspects of ethics: o Personal ethics - Ethical decisions are critical to long-term success of any organization. However, supply chain is particularly susceptible to ethical lapses (error in judgement) - Issues include bribery and conflict of interest - Institute for Supply Chain Management has developed principles and standards to be used as guidelines for ethical behavior: - Promote and uphold responsibilities to one’s employer o Positive supplier and customer relationships o Sustainability and social responsibility o Protection of confidential and proprietary information o Applicable laws, regulations and trade agreements o Development of professional competence - Avoid perceived impropriety o Conflicts of interest o Behaviors that negatively influence supply chain decisions o Improper reciprocal agreements o Ethics within the supply chain Indicates an increase no. of facilities implies a quicker response and increased customer satisfaction Shows 3 logistic-related costs: inventory costs, transportation costs, and facility costs Total logistics cost tends to follow the top curve, first declining, and then rising Total costs are minimized with 3 facilities When revenue is considered, profit is maximized with 4 facilities
  • Firms use SCOR to identify, measure, reorganize and improve supply chain processes

SUPPLY CHAIN MANAGEMENT ANALYTICS Techniques for Evaluating Supply Chains

  • Evaluating Disaster Risk in the Supply Chain o Firms often use multiple suppliers for important components to mitigate the risks of total supply disruption o A decision tree can be used to help operations managers make important decision regarding the number of suppliers
  • S – probability of super event that would disrupt all suppliers simultaneously
  • U – probability of unique event that would disrupt only one supplier
  • L – financial loss incurred in a supply cycle if all supplies were disrupted
  • C – marginal cost of managing a supplier
  • Assuming that probabilities are independent of each other, the probability of all n suppliers being disrupted simultaneously equals:
  • P(n) = S + ( 1 − S)𝑈𝑛
  • Managing the Bullwhip Effect o The overarching solution to the bullwhip effect is simply for supply-chain members to share information and work together o Supplier coordination can help with demand shifts o Coordinated planning can help alleviate shortages and delays that might otherwise occur as the bullwhip snaps backward o
  • Describes the tendency for larger order size fluctuations as orders are relayed to the supply chain from retailers o A Bullwhip Effect Measure
  • A straightforward way to analyze the extent of the bullwhip effect at any link in the supply chain is to calculate bullwhip measure
  • Bullwhip > 1 : Variance amplification is present o Size of company’s orders fluctuate more than the size of its incoming demand
  • Bullwhip = 1 : No amplification is present
  • Bullwhip < 1 : imply smoothing or dampening scenario o Orders move up the supply chain toward suppliers
  • Supplier Selection Analysis o Buyers may consider such supplier characteristics like product quality, delivery speed, delivery reliability, customer service and financial performance o Factor-weighing technique
  • Simultaneously considers multiple supplier criteria
  • Transportation Mode Analysis o Aside from holding cost vs shipping cost, there are many other considerations for operations or logistics manager including:
  • Ensuring on-time delivery
  • Coordinating shipments to maintain a schedule
  • getting a new product to market
  • keeping customer happy
  • Warehouse Storage o Storage represents a significant step for many items as they travel through their respective supply chains o Care should be taken when determining which items to store in various locations in a warehouse o Proper placement of items can improve efficiency by shaving significant travel time for workers
