creating a “supply chain city” in Dongguan, Southern China
Best Buy’s reduced orders did what further down the chain
Suppliers all across the chain reduced production over reacting to the original reduction adding at each level until at the bottom of the chain until Best Buy had shortages of stocks despite decline in demand
What does RFID stand for
Radio frequency identification. Computer chips or smart tages attached to items as they are transported through the chain. Use wireless technology to track inventory. Walmart was early adopter. Can save money on labor and help to manage inventory more effectively . WalMart spending at 4.6 B in 2007.
Why was WalMart interested in the investment of RFID technology

Supply Chain
How is downstream determined in a supply chain?
Supply chain going toward the final product and the ultimate customer.
The ultimate consumer may be a supplier in another chain.
Can have multiple upand down stream customers and suppliers
How is upstream determined in a supply chain?
Supply chain going toward the raw materials. Through the various suppliers.
What flows along the supply chain
Goods plus information, funds, papaer, people and other items flowing in both directions.
Should think of as a process rather than chain.
Involves functional areas and activities such as product/service design, finance, accounting, marketing, human resources and engineering.
What is SCM
Supply Chain Management. Involves process of managment of entire chain from order at ultimate consumer back to raw materials (upstream)
Who is best known for their perfection of Supply Chain Management and Lean manufacturing?
Toyota – teach their suppliers their methods, then give incentives for their suppliers to teach their suppliers so that efficiencies are carried over the chain upstream to raw materials. This gives overall saving to ultimate consumer downstream.
Give reasons why SCM has exploded grown in interest
New information technologies such as intranets, email, EDI and Internet.
Greater global competition has increased our interest and ability to improve processes along the entire chain.
SCM also includes what mangerial thrusts
Quality management.
Inventory management,
enterprise resource planning and lean production (JIT)Also includes marketing, engineering, product/service design, financial aspect in terms of payments and float, purchasing elements such as sole sources and tehcnological inintiatives .
Can all be attributed to the advent of the internet.
What is the focus of the value chain
Customer values of timeliness
quality
function.
Supply chain focuses on efficiency
How do the value chain and the supply chain differ
Supply chain focuses one efficiency
value chain focuses on timeliness, quality and function which are customer values
Pull systems consist of what?
Just-in-time deliveries
lean manufacturing
Dictate a different view of the value chain called a demand chain.
Order coming from customers generate a pull of products through the supply chain.
By using the pull system suppliers can order just what they need for the order.
Demand Chain
Customer orders pull the product through the chain, improving cost and benefits. Related to Lean manufacturing
Manufacturing oriented supply chains goods tend to flow
in one direction downstream.
Service supply chains and dual customer supplier role
services flow in both directions with the customer both upstream and downstream from the service provider.
What cost can be eliminated through the use of better information sharing and managerial oversight

How much did Palm Inc save through their strategic emphasis on supply chain management
20-30% reduction in materials costs
27% reduction in overall costs
Increase in inventory turns from 3 to 22
30% increase in profit margins
What is the focus of the supply chain management crusade
Focus on entire value chain
Lean production
JIT
TQM
Purchasing
Product/service design
Define Supply Chain Management
Coordination and integration of all supply chain activities into seamless process
Enables organizations to plan and collaborate across supply chain
Goal is to deliver right product to right place at right time in order to maximize profit
Another definition for Supply Chain Managements
Supply, storage, and movement of materials information, personnel, quipment, and finished goods within the organization and between its environment
What is the goal of supply chain management
To integrate the entire process of satisfying the customers’s needs all along the supply chain.
What is a 3PL
3rd Party Logistics company.
What can a 3PL do
Handle the distribution of the organizations products, receiving incoming materials, managing the organization’s warehouses, managing the purchasing function, and handling product returns.
Balance of activities as to what is done inhouse to those outsourced varies by business
Why would a company outsource to a 3PL
Allows the company to focus on its core competencies
Reduces the capital investments in the infrastruct needed to support these activites
Converts a significant portion of what was a fixed cost into a variable cost
Gains access to the best practices and technologies that it might not be able to afford or develop if the function was kept in house.
What is one requirement of a Supply chain strategy?
Strategy needs to be tailored to meet the needs of its customers, not always lowest cost
Examples:
With basic commodities then cost reduction is focus
With fashion goods, timieliness
What part of total operating expenses do supply chain costs represent
More than 50% and in some cases 75%
What is included in the broad concept of supply chain
Supply storage
Movement of materials
Information
Personnel
Equipment
Finished goods within the org. and between it and its environment
AS efficiency improves in production techniques what has what is taking a greater and greater fraction of the total cost and time
Procurring the requisite inputs and distributing the resulting goods and services
What are some measures of supply chain performance
Lower inventories – means less Working Capital needed and higher ROA ratio
Lower cost to carry inventories will be seen in a reduced cost of goods sold (COGS) and so a higher contribution margin, return on sales and operating income.
Where is a lower inventory cost reflected
In Working capitals being lowered and Return on asset ratio being higher
Lower cost to carry inventory will be seen in:
reduced cogs and higher contribution margin, return on sales and operating income.
Cash Conversion Cycle
Helps assess how well a company is managing its capital
Amount of time the organizations cash is tied up in working capital before being retuned by customers as they pay for delivered products or services
How is the Cash Conversion Cycle calculated
CCC = I +AR-AP
Inventory (I) =( Inventory/Annual COGS) X 365
Accounts Receivable (AR) = (AR/Annual Net sales) X 365
Accounts Payable (AP) =(Accounts Payable/Annual COGS) X 365
Inputs must be standadized into days
If CCC is positive then?
# days capital is tied up waiting for payment
If CCC is negative then?
# days organization can receive cash from sales before paying suppliers. The smaller the better
Where should a company locate if they process natural resources
Near the resource if there is a loss in size or weight during the process
High economies of scale exist for the product

Example: television and electronic manufactueres
What is a contract manufacturere
outsource entire process to 3rd parties. Core competency is in system innovation or design. is a major element of SCM strategy for firms like Cisco, Dell , IBM. Considered manufacture service providers
What can be outsources with less consequences
Things that are not core competencies,
Things like accounting, human resources, R&D even product design and IT
Why is supply chain in important
Because it represents 50% or more of total operating cost
Can save a lot of money through better management of the supply chain
How is procurement different from purchasing
purchasing implies a monetary transaction
procurement is the responsibility for acquiring the goods and services the organization needs by any means. – includes scrap and recycles as well as purchased materials. Procurement can make consideration of environmental aspects
What is reversed logistics
Where packaging must reverse the logistics chain and flow bact to the producer who originated it for disposal or reuse.
Why is a supply chain so important

AAIV – aggregate average inventory value
Raw materials + Work-in-process + finished goods
% Assets in Inventories
AAIV/total assets
Turn over of Inventory
Annual COGS/AAIV
Days of supply
AAIV/Daily COGS to do weekly divide by weekly COGS or multiply daily amount by 7 and then use to divide.
