3. Definition of Supply-Chain
Rajeev Sawhney, Western Illinois University
Definition of Supply-Chain
All the activities involved in delivering a product from raw material through to the customer including
Sourcing raw materials and parts
Manufacturing and assembly
Warehousing and inventory tracking
Order entry and order management
Distribution across all channels
Delivery to the customer
Information systems necessary to monitor all activities

4. Functions of supply-management department

Forces Driving Changes
Impact of globalization
World redefined – opening up of economies
EU, NAFTA, SAFTA and other such bodies promoting free trade
Emergence of China and India
Need to streamline production operation and outsource for maximum efficiency
Fuel price increase – 11.6 cents per mile in 1976 to 24.6 cents per mile in 1985 and de-regulation
Logistical solutions

Container management
Reverse logistics
Waste management - cradle to cradle design issues

6. Rajeev Sawhney, Western Illinois University
Continued…..
Cost-plus system, pull-system, make-to-order (mass production to mass customization) – all require more active supply-chain involvement
Total quality management, just-in-time manufacturing, ERP – all require integrated supply chains for best results.
Greater computing power allowing more sophisticated inventory planning systems.
Technology – electronic networking and automating repetitive tasks to allow more time for value added work
Business school interests

7. Supply Chain Management
Unreliable deliveries either increase inventory investments in safety stocks or result in unsatisfied customers and lost sales
Success is achieved only by formation of effective partnerships and cooperation among participants throughout the entire supply chain
Bullwhip effect – when a small change in retail order is magnified as we move back up the supply chain to the distributor and finally to the customer – due to overreaction caused by lack of integration and trust

8. Network model
The physical goods supply chain can be viewed as a network of value adding material processing stages each defined with supply input, material transformation, and demand output.
Fig shows these stages as suppliers, manufacturing, distribution, retailing and recycling – depicting the flow of material by an arrow, with inventory stocks at each stage.
Information transfer is in the opposite direction – shown by dashed lines. Lack of proper information flow creates uncertainty and results in inventory holding.

9. Supply Chain for Physical Goods fig. 15.1

10. Managing Uncertainty
Uncertainty in supply chain arises from three major sources:
Supplier delivery performance
Manufacturing unreliability
Customer demand
Inventory is traditionally used to match uncertainty

11. Supply chain strategic planning
Strategic initiatives can lessen the impact of uncertainty and thus improve customer service
Improve manufacturing reliability through TQM
Dependable transportation modes
Modular design – allowing postponement of final customization – thus increasing responsiveness without holding too much inventory ; ex. 110 volts versus 220 volts – need changes according to geographic regions, so distribution centers add value by making this customization as the last step
Information technology allows tracking the movement of goods through the supply chain from the factory to the retailer – greater transparency in the logistics system reduces uncertainty

14. Service Supply Relationships
Service can be considered as acting on people’s minds (e.g. education, entertainment), bodies ( e.g. lodging, health care), belongings ( e.g. auto repair, dry cleaning), and information ( e.g. insurance, legal) – thus all services act on something provided by the customer.
Therefore, customers are acting as suppliers in the service exchange – called the customer-supplier duality (see fig. 15.2). There is a bidirectional relationship between the service delivery firm, its supplier, and the customer (see table 15.2).
Table 15.3 shows examples of two-level service supply chains. In each case, the service provider requires the assistance of a third party supplier to complete the service.

17. Managerial Implications of Bidirectional Relationships
Service supply relationships are hubs, not chains
Simultaneous consumption and production makes services more like hubs than chains (in sequence)
Table 15.3 – where supply chain can be extended to include a supplier to the service provider, where service provider acts as an agent for the customer when dealing with outside supplier
Service capacity is analogous to inventory
For goods supply chains, inventory is used to buffer the variations in final customer demand
Services cannot be inventoried, excess capacity must be held in reserve

18. continued Customer supplied inputs can vary in quality
Thus impacting delivery performance of service provider
Effective communication is ,therefore, very important

19. Sources of Value in Service Supply Relationships
Value in service supply relationship depends on
bi-directional optimization
Management of productive capacity
Management of perishability

20. Bidirectional Optimization
Bi-directional Optimization implies the possibility of doing what is the best from the customer’s perspective while doing the best for the service enterprise
It is simultaneous optimization of both supply and demand for the service

21. Management of Productive Capacity
Strategies to improve productive capacity of the service worker are follows:
Transfer: make knowledge available to customers so that value can be transferred with very low cost. Example, web based FAQ database can be used instead of human resources to answer questions
Replacement: substitute technology for server (e.g. digital blood pressure device)
Embellishment: enable self-service by teaching (e.g. change surgical dressing)

22. Management of Perishability
Reduce idle time of workers because that is lost capacity
If you can communicate with workers then you can change their schedule to optimize capacity. If no communication is available then you have to work with a fixed schedule and cannot deal with uncertainties in the best possible way.
Managing perishability also involves training and extending skills and capabilities of workers to work at more than one station – to match changing needs

23. Relationship between stakeholders – how is service purchasing different?
Simultaneous production and consumption, thus requiring user participation.
Inability to store services – implying that the timing of service delivery must coincide with the end users consumption needs. Therefore, the end user must communicate the needs to the purchasing manager very precisely – otherwise the consequences of improper timing may be serious and costly.
Inability to store services creates quality assurance difficulties. It may not be possible to inspect a service before its delivery. Therefore, services have to be continuously monitored by the end user.
Dr. Rajeev Sawhney

24. Relationship between stakeholders – how is service purchasing different?
The need-recognition and description stages of acquisition process offer the greatest opportunity to add value through strong collaborative relationship with internal users. Otherwise, the organization will fail to realize the full contribution in managing its service spend. Therefore, purchasing managers must become business partners with major users of the services.
Greater effort upfront in identifying and documenting for intangibles will facilitate supplier search and selection, administration, and quality control.
Dr. Rajeev Sawhney

25. Relationship between stakeholders in a service purchasing environment
Purchasing services directly by the end user is not recommended because often they are inadequately prepared to apply a methodical, structure, and strategic sourcing process to the purchase.
Purchaser has the skills to put the entire package together – in terms of timing (preventing rush orders), coordinating the entire needs of the organization, exploring the inter- relationship between different services and their suppliers, and procuring them at the best price.
Typically when qualified procurement personnel are involved in the planning and procurement of services, savings of approximately 25 % are enjoyed with equal or improved quality and service.
Dr. Rajeev Sawhney

26. Relationship between stakeholders in a service purchasing environment
There is a greater intangible component in services than in manufacturing. Therefore, early involvement of service suppliers can often provide value, especially when the service is complex and technical.
Dr. Rajeev Sawhney

27. Key questions that help in need recognition and description of service
Why is this service necessary?
What is important to know about this service?
How is this service produced?
Where is the service being delivered?
How is quality defined for this service?
How do we know we received what we expected?
Dr. Rajeev Sawhney

28. Outsourcing Services
Benefits - allows the firm to focus on its core competence - service is cheaper to outsource than perform in-house - provides access to latest technology - leverage benefits of supplier economy of scale
Risks - loss of direct control of quality - jeopardizes employee loyalty - exposure to data security and customer privacy - dependence on one supplier compromises future negotiation leverage - additional coordination expense and delays - atrophy of in-house capability to perform service
