Trang 21 Bullwhip Effect – Case study
Procter & Gamble (P&G) examined order patterns for Pampers.
Its sales at retail stores were fluctuating, but the variability was not excessive.
For the distributors' orders, P&G was surprised by the greater degree of variability.
When they looked at P&G's orders of materials to their suppliers, such as 3M, the swings were even greater.
While babies consumed diapers at a steady rate, the demand order variability in the supply chain was amplified as we move up the supply chain P&G called this phenomenon the "bullwhip" effect.
ECR: Potential $30 billion opportunity
Efficient Consumer Response (ECR)initiative
One motivation for the initiative was theexcessive amount of inventory in the supplychain
Studies found more than 100 days ofinventory supply from production lines toretailers' shelves
Distorted information led to stockpilingbecause of demand uncertainty andvariability

Trang 4Causes of the Bullwhip Effect
Best illustration of the bullwhip effect is "beer game."
Participants play the roles of customers, retailers, wholesalers, and suppliers of a popular brand of beer.
They cannot communicate with each other and must make order decisions based only on orders from the next downstream player.
The ordering patterns share a common, recurring theme: the variability of an upstream site is always greater than those of the downstream site, a simple, yet powerful illustration of the bullwhip effect.
the bullwhip effect is a consequence of the players' rational behavior within the supply chains infrastructure.

2 Pull and Push System
Trang 6Pull Strategy
- Coordinate production and distribution based on actual needs and orders
- Receiving orders – Sourcing – Producing/assembling – Delivering
- Meet the requirement of market, quick response and high quality service
- Reduce stagnant capital, increase inventory turnover.
- Strict requirements: flexible organization, scientific production management, integrated information system, on time
Characteristics of products and market
- Production and distribution based on forecasting.
- Low volatile demand
- Low customized
- High Economies of scale
- Production and distribution based on real demand
- High volatile demand
- Customized products
- Low Economies of scale

Many time per day, at the Assembly line
All components are attached to the orders
No finish product is assembled before the order comes
- Dell’s production department only stores a small amount of components and they comes before few hours
- The responsiveness of Dell depends directly on supplier’s competence
- Absolute synchronization between production and sales, keep the supply chain always balanced and smooth
Trang 9Why is there such a change?
Push and Pull Strategy
- Push and pull Coordination: take the advantages of 2 strategies
- The first part of the chain: Push
- Store components based on long term forecasting
- Semi – products are assemble to modules
- The last part of the chain: Pull
- Assemble based on real demand
- Complete products after receiving orders

3 Supply Chain Design
Supply chain strategy must be aligned with overall corporate strategies
Supply chain performance goals must be stated in operational terms: projected market coverage, sales and service support, sale volume, profitability, inventory turns, cash to cash cycle times and return
Trang 113 Supply Chain Design
Phase 1: Understanding end customer
Phase 2: Choosing best SC’s strategy
Phase 3: Scoping the SC’s structure
Trang 12Phase 1: understand the need of customer
The customer is the ultimate judge of the supplychain’s performance
Organizations must understand the nature of theirproducts and be able to devise a supply chainstrategy that best fits their customers’ needs ordemands
Primarily functional or primarily innovativeproducts
Trang 13Customer service objectives
The level of product availability
The speed and consistency of the customer’sorder cycle
The communication that takes place betweenseller and customer
Reflecting the customer’s view of customerservice And the product’s importance to thecustomer and the customer importance to thecompany
Trang 14The former allows them to plan inventory levels
to a greater extent than is possible with a fastbut highly variable order cycle
Communication
Firm’s ability to supply timely information tothe customer regarding such factors as: orderstatus, order tracking, back-order status, orderconfirmation, product substitution, productshortages, and product information requests
Automated information system usually results
in fewer errors in shipping, picking, packing,labeling and documentation
Trang 15Phase 2: Selecting a supply chain strategy
A supply chain strategy can be defined as astrategy required to manage the integration ofall the supply chain activities throughimproved supply chain relationships in order toachieve a competitive advantage for the supplychain (Hines, 2004: 5)
Supply chain strategies may be designed to bemore efficient and/or to be more responsive

Trang 16Postponement >< Delay ???
Postponement makes SC:
More Flexible Reduce cost due to reduce the complexity
Postponement ways:
Manufacturing Postponement Logistics Postponement
Throughout from the origin to the destination
Process and IT are integrated inside and outside the firm to the customers and main suppliers
Production capacity and inventory are optimized throughout the SC
Performance indicators and qualitative objectives are shared throughout the SC
Trang 17Efficient (or lean) supply chains
An efficient (or lean) supply chain is a set oforganizations directly linked by flows ofinformation, products and finances that workcollaboratively to reduce cost and waste
eliminated, scale economies should be pursuedand optimization techniques should be deployed
to get the best capacity utilization in productionand distribution
Lean supply chains are thus appropriate for andmatch functional products
Responsive (or agile) supply chains
The focus of agile supply chains is on timecompression and quick response and oneliminating the barriers to quick response
Supply chain agility is the ability of the supplychain as a whole to rapidly align the network andits operations to the dynamic and turbulentrequirements of customers’ demands
Agile supply chains are relevant for innovativeproducts

Trang 20A combination of lean and agile supply chains
Hybrid (or ‘leagile’) supply chains exploitthe benefits of both lean and agile supplychains
The decoupling point is the point in theproduct ow stream to which the customer’sorder penetrates and where real time data andforecast- driven activities meet
What is the organisation’s position in terms
of the decoupling point?
Which supply chain strategy should beadopted by the organisation?
Trang 21Phase 3: Scoping the supply chain structure
The supply chain structure implies theintegration of the links between supply chainmembers
Identifying and collaborating with only thecritical primary supply chain members (whichcan be beyond tier one) allows an organization toshare relevant information and to concentrate itstime and resources on managing the importantprocess links, enabling the supply chain toperform well

Customer buying behavior: potential customer segment
Ability to link up processes,
Ability to grow with the business
Competing supply chain
Control: other members to ensure product quality or purchase services for long – term profitability
post-Product characteristics
The product’s value
The technicality of the product
The degree of market acceptance
The degree of substitutability
The product’s bulk
The product’s perishability
The degree of market concentration
Seasonality
The width and depth of the product line
Trang 23Value of the product
High per unit cost large inventoryinvestment require shorter supply chains
Low unit cost longer supply chain
Low value: shipped by rail, ships and stored
in field warehouse
High value: shipped by air freight tominimize in-transit inventories to reduce ICCand markdowns
Technicality
High technicality products: demonstration by
a sale-person as well as pre-purchase andpost-purchase service
Ex: home computer, high – priced stereocomponents, expensive cameras and videoequipment, imported sports cars…
Direct channels and selective or exclusivedistribution policies are used
Trang 24Market acceptance
A leading manufacturers offers a newproduct and plans significant introductoryadvertising, customer acceptance will behigh and intermediaries will want to carrythe product
New product with little market acceptanceand low brand identification requireaggressive selling
Substitutability
Related to brand loyalty:
Low brand loyalty: product substitution islikely and intensive distribution is required,firms place a premium on point of purchasedisplays in high traffic areas
To gain support from wholesalers or retailers,the producer may offer higher than normalmargins: selective or exclusive distributionmakes product support easier
Trang 25Low value, high – weight products arerestricted to markets close to the point ofproduction, require special material handlingskills
Low weight and small cubes: more units can beshipped in a truck, rail, container reduce theper – unit cost of transportation
Perishability
Refers to physical deterioration or to productobsolescene caused by changing customerbuying patterns or technological change
Perishable products are usually sold on a directbasis in order to move product through thesupply chain more quickly and reduce thepotential for inventory loss
Trang 26Manufacturers might offer a seasonal discount
or consignment inventories to wholesalers orretailers who agree to take early delivery
Trang 27Width and depth of supplier’s product line
A manufacturer of products with low per –unit values may use intensive distributionwith direct sales if the product line is broadenough to result in a relatively large averagesales volume
Ex: Vinmart, …
A manufacturer of a limited line of productswill use wholesalers to achive adequatemarket coverage at a reasonable cost
Value proposition to meet customers’ needs
A value proposition is a statement of how, whereand when value is to be created for specificcustomers
Value is created when core competencies (orcapabilities) are built
A core competency is de ned as a bundle of skillsand capabilities that enable an organisation toprovide a particular bene t to customers
