Supply Chain Management

supply chains are_____ through various processes and technologies

enabled

forecast

estimate of future demand

SCM: 1950s & 60s

-1950s: origin of SCM -> limited to materials management and logistics -US manufacturers maintained large material inventories to keep production running -> focused on producing as much product as possible at the min cost -manufacturers internally focused : focused on mass production techniques to reduce cost and increase productivity -external collaboration and partnerships virtually nonexistent

sustainability and "greening" the supply chain

-Customers increasingly prefer products that are made and sourced in 'the right way' -> minimizing business' social, economic and environmental impact on society and enhancing positive effects. -Large majority (75%) of U.S. consumers influenced by a firm's environmental friendliness reputation

SCOR: Deliver

-Logistics phase -oversees planning and execution of the forward flow of goods and related information -coordinate the receipt of orders, develop a network of warehouses, pick carriers to transport products to customers, set up an invoicing system for payments, etc.

supply management elements

-Purchasing -supplier management -strategic partnerships -ethics and sustainability

supply chain cost optimization

-Reducing purchasing costs, waste, excess inventory, non-value added activities -Improving demand planning -Increased outsourcing of non-core competencies.

tier 1 supplier/customer

-an organization's immediate supplier vs an organization's immediate customer -some organizations can be both a supplier and a customer -it is important to identify tier 1 supplier/customer first to build a relationship

multiple supply chains

-any organization offering a product or service has a supply chain -supply chains can be simple or complex -everyone is involved in multiple supply chains

SCM: Today and Beyond

-companies focus on their own core competencies and outsource the rest -companies focus on: building relationships, sustainability, corporate social responsibility, improving supply chain capabilities

SCM: 1980s & 1990s & 2000s

-companies start incorporating supply chain partners into planning activities -Just in Time -Total Quality Management -Business Process Reengineering

SCM: new paradigm

-company focuses on its area of expertise and enters trust based relationships with suppliers and consumers -all participants benefit -boundaries are dynamic = extend end to end -supply chains also deal with reverse logistics

SCM: old paradigm

-company gained synergy as a vertically integrated firm encompassing the ownership and coordination of several supply chain activities -organizations emphasized short term, company focused performance

supply chain

-coordination of a network of independent organizations all involved in creating a desired product or service, and moving it from suppliers out to consumers, when and where they want it

Measures of success (examples)

-customer service -demand plan conformance -supply plan conformance -inventory plan conformance -cost of goods sold (COGS)

independent demand

-demand for an item that is unrelated to other items, such as a finished product, a spare part, or a service part -demand is FORECASATED

Globalization

-expanding the supply chain -international, mature, and emerging markets have become part of the overall business strategy for many companies -both breadth and depth of global operations

SCOR: Enable

-facilitate a company's ability to manage a supply chain -not a stage that occurs sequentially with the others -Examples:Supply Chain Systems and Network Operations , Systems Configuration Control, Interfaces, Gateways, Database Administration , Electronic Data Interchange (EDI), Telecommunications Services, Performance, Measurement, Contract Management, Business Rules, Standards, Training and Education

operations management elements

-forecasting & demand planning -planning systems -process management

qualitative forecasting

-generally used when data is limited, unavailable, or currently irrelevant -forecast depends on skill and experience of forecasters and available info

benefits of supply chain management

-improved customer service -increased revenue -lower costs -better asset utilization -adds customer value/retain customers -minimize delays/shorter lead times -elimination of rush (unplanned) activities -reduced uncertainty throughout the entire supply chain -lower inventory levels throughout the supply chain -ability to respond to disruptions and conflicts

strategic partnerships

successful and trusting relationships with top-performing suppliers

intense global competition led US manufacturers to adopt

supply chain management

SCOR model

Plan, Source, Make, Deliver, Return, Enable

main reason companies implement supply chain management

achieve cost savings and better coordinate resources

Demand-side shock absorber

inventory

intangible products

products that cannot be physically touched

improving supply chain capabilities

-increased use of third party logistic service providers -integrating logistics internally and with external trading partners -using transportation to facilitate rapid response and delivery

Total Quality Management

-management approach to long term success through customer satisfaction -based on the participation of all members in an organization in improving processes, goods, services, and the culture in which they work -everyone in the organization takes ownership for quality

risk management

-many companies have started shifting supply chain risk (such as holding inventory) upstream to their suppliers, and shipping finished product directly to customers -supply chain risk can only be mitigated by managing risk at every node of the supply chain

SCOR Model: Plan

-planning establishes the parameters within which the supply chain will operate -companies need a strategy for managing all of the resources necessary to create and deliver a product that meets consumer needs -includes: determination of marketing and distribution channels, promotions, quantities, timing, inventory and replenishment policies, and production policies

SCOR model: Source

-process of identifying the suppliers that provide the materials and services needed for the supply chain to deliver the finished products desired by the customers -identify reliable suppliers and build strong relationships with them -develop pricing, shipping, delivery, and payment processes with suppliers and create metrics for monitoring an improving the performance

SCOR: Return

-reverse logistics -planning and controlling the process of moving goods from the point of consumption back to the point of origin for repair, reclamation, re-manufacture, recycle, or disposal -create a responsive and flexible network for receiving defective and excess products back from their customers

SCOR: Make

-series of operations performed to convert materials into a product -finished product is manufactured, tested, packaged, and scheduled for delivery -quality management is the most important part of scm -most metric intensive portion of the supply chain: companies able to measure quality levels, production output, and worker productivity

scm in the service industry

-services generally cannot be produced in advance or inventoried -frequently the customer provides the tangible item that will receive the service -customers play a vital and more important role in the delivery aspect of the supply chain -service supply chain is more about managing the relationships between trading partners than it is about managing the chain of supply

integration elements

-supply chain process integration -supply chain risk assessment and mitigation -supply chain performance measurement

SCM demand-side challenges

-training and development -r&d requirements -independent demand -scheduled maintenance -sample requirements -safety stock -trade requirements

SCM supply-side challenges

-transportation -supplies and materials -labor -money -warehouse and storage space -quality control -lead time -production and inventory -equipment and facilities

logistics management elements

-transportation management -customer relationship management -network design

Supply Chain Process Integration

-when supply chain participants work for common goals -requires intra-firm functional integration -based on efforts to change attitudes and adversarial relatoinships

fundamentals of forecasting

1) Your forecast is most likely wrong 2) Simple forecast methodologies trump complex ones 3) A correct forecast does not prove your forecast method is correct 4) If you don't use the data regularly, trust it less when forecasting 5) All trends will eventually end 6) It's hard to eliminate bias, so most forecasts are biased 7) Technology is not the solution to better forecasting

five qualitative models

1. Personal Insight 2. Jury of Executive Opinion 3. Delphi Method 4. Sales Force Estimation 5. Customer Survey

two important considerations about a forecast:

1. forecast will be inaccurate but useful 2. forecast is the basis for most downstream supply chain decisions

current trends in SCM

1. globalization 2. demand volatility and forecast inaccuracy 3. supply chain cost optimization 4. risk management 5. sustainability and "greening" the supply chain

Elements of SCM

1. operations management 2. supply management 3. logistics management 4. integration

two basic forecasting techniques:

1. qualitative: based on opinion and intuition 2. quantitative: uses mathematical models and historical data

demand volatility and forecast inaccuracy

=Firms will increasingly need to be more flexible and responsive to customer needs adapting to unexpected changes and circumstances. -Necessitating closer integration and collaboration

SCM: 1950s & 60s pros and cons?

Advantages: -higher output and more productivity -reduced cycle times -lower in-process inventories Disadvantages: -high investment in facilities -overall cycle time limited by the slowest operation -breakdown of one machine will halt the entire production

Supply Chain Performance Measurement

Crucial for firms to know if procedures are working

who benefits the most from supply chains?

Firms with: -large inventories -large number of suppliers -complex products and/or large number of products -large purchasing budgets/expenditures

Step 1: Forecasting

Forecast is developed through data analysis and judgement -organizations must have a formal forecasting process to develop an agreed upon set of numbers that becomes the driver for demand planning

Business Process Reengineering

Fundamental rethinking and radical redesign of business processes to achieve dramatic improvements in cost, quality, speed, and service

good vs bad forecasting

Good: can benefit a company by facilitating more effective planning =>reduced inventories, reduced costs, reduced stockouts, and improved customer service Bad: root cause for ineffective planning, everything based on the forecast will be bad => garbage in, garbage out

product and service flow

Involves movement of goods and services from suppliers to customers as well as handling customer service needs and product returns

payment flow

Transfer of monies among companies as payment for merchandise or services rendered (flows opposite to product and service flow)

forecasting

business function that estimates future demand for products so that they can be purchased or manufactured in appropriate quantities beforehand

ERP (Enterprise Resource Planning)

business process management software that allows an organization to use a system of integrated applications to manage the business and automate many back office functions related to technology, services and human resources

network design

creating distribution networks based on trade-off decisions between cost & sophistication of distribution system

benefits of a supply chain

delivers VALUE by managing the processes of all the otherwise independent trading partners so they collaborate with each other in the most efficient, effective, and cheap way

dependent demand

demand for an item that is directly related to other items or finished product, such as a component used in making a finished product -demand is CALCULATED

supplier evaluation

determining the current capabilities of suppliers

World class operational excellence begins with

effective supply chain planning and control techniques which: 1. provide a single set of numbers used to run the business 2. generate significant improvements in customer service, productivity, inventory and costs

warehouses

facilities that allow companies to store materials and finished products

supply side shock absorber

flexibility

____ and ______ are crucial components for customer satisfaction

forecasting and demand planning

general supply chain flow

from supplier to customer -information flow (both ways) -product and service flow (s to c) -payment flow (c to s) -returns flow (c to s)

Manufacturing Resource Planning (MRP II)

helps to improve internal communication and operations. (Manufacturers extended their processes to include their own finance, marketing, sales, research and development, etc. functions to bring all their expertise into the process.)
