Supply Chain Management
• Value Chain
• Supply side- raw materials, inbound
logistics and production processes
• Demand side- outbound logistics,
marketing and sales.
WHAT IS SUPPLY CHAIN MANAGEMENT
" Is the strategic management of activities involved in
the acquisition and conversion of materials to finished
products delivered to the customer"
Leads to Business Process Integration
• Supply chain is the system by which
organizations source, make and deliver
their products or services according to
• Supply chain management operations
and decisions are ultimately triggered by
demand signals at the ultimate consumer
• Supply chain as defined by experienced
practitioners extends from suppliers’
suppliers to customers’ customers.
• SUPPLY CHAIN INCLUDES :
– MATERIAL FLOWS
– INFORMATION FLOWS
– FINANCIAL FLOWS
• SUPPLY CHAIN MANAGEMENT
FACILITATED BY :
• Supply chain objectives may differ from
situation to situation.
• For functional products, cost efficiency is
the critical factor.
• For innovative products, responsiveness
is the important factor.
• Leanness + Agility together make up
Supply Chain Structure
Supply Chain and Demand Chain
• Demand chain is defined as the system by
which organizations manage sales and
distribution of products and services to end
• Conceptually incorrect to look at demand
• Look at the pipe as a whole.
• But is there a pipe at all?
– More a network
– Not necessarily linear
• Value chain orchestration rather
controlling the flow through the pipe
• A network of independent and interdependent
organizations mutually and cooperatively
working together to control, manage and
improve the flow of materials and information
from suppliers to end users
SUPPLY CHAIN DRIVERS
Not new. Value system of Michael Porter
• Why sudden interest?
– Demanding customers
– Shrinking product life cycles
– Proliferating product offerings
– Growing retailer power in some cases
– Doctrine of core competency
– Emergence of specialized logistics providers
– Information technology
SUPPLY CHAIN ELEMENTS

• Supply Chain Goals
Efficient supply chain management
must result in tangible business
improvements. It is characterized by a
sharp focus on
– Revenue growth
– Better asset utilization
– Cost reduction.
Co-operation (Cross -Functional)
Communication (Real Time Data)
Reduce Overall Cycle Time : Improve Response
Functional vs Process
Products vs Customers
Revenues vs Performance
Inventory vs Information
Transactions vs Relationships
Critical Success Factors today
• Cross functional management and
• Ability to define, measure and manage
• Information systems
• Relationship management and win win
PUTTING IN PLACE A WELL OILED SUPPLY
• Supply chain as an efficient customer
• Effectiveness of the whole supply chain is
more important than the efficiency of each
The steps involved
• Step1- Designing the supply chain
– Determine the supply chain network
– Identify the levels of service required
Step 2 - Optimizing the supply chain
• Determine pathways from suppliers to
the end customer
Customer markets to Distribution centers
Distribution centers to production plants
Raw material sources to production plants
Identify constraints at vendors, plants and
– Get the big picture
– Plan the procurement, production and
distribution of product groups rather than
individual products in large time periodsquarters or years
Step 3- Material flow planning
• Determine the exact flow and timing of
• Arrive at decisions by working back from the
projected demand through the supply chain to
the raw material resources
Step 4 - Transaction processing and
short term scheduling
• Customer orders arrive at random
• This is a day to day accounting system which
tracks and schedules every order to meet
• Order entry, order fulfillment and physical
Information flows in Supply Chain Management
• Information is overriding element
• Need for databases
• Master files: Information about customers, products,
materials, suppliers, transportation, production and
distribution data- do not require frequent processing
• Status files- heart of transaction processing- track
orders and infrastructure status- updated daily.
• Essentially using the same information to make all
plans right from structuring the network to
processing every day supply chain tasks.
THE VIRTUAL VALUE CHAIN
• The value chain connects a company’s
supply side with its demand side.
• Traditionally information has been a
• Information however can be managed
far more creatively.
• There are various stages of using value
added information processes.
• Visibility : See physical operations more
effectively through information. Information
can be used for effective coordination of
value chain activities.
• Mirroring capability : In this stage, virtual
activities are substituted for physical ones. A
parallel value chain is created.
• New customer relationships : The company
can draw on the flow of information in the
virtual value chain to deliver value to
customers in new ways.
Inventory ownership and management
Sales and technical support
• Channels being divided into two- Fulfillment
and Franchised agent
• Fulfillment channel- responsible for getting
the manufacturer’s product from the plant to
the end user through a highly efficient
logistics and inventory management system
• Fulfillment channel may not take ownership
of the product but may perform these
functions on a per box fee structure
• Franchised agents responsible for sales and
sales support but will not write the order or
supply the product
Issues in customer management
• Penetration vs Spread
• Concentration is necessary to commit the
necessary resources for true customer
• Depth of customer contact
– R&D - sharing information vs developing new
– Logistics - Pros and cons of methods of
transportation vs reengineering the logistics
Implementation: Points to keep in mind
• Recognize the difficulty of change.
• Prepare a blueprint for change that maps linkages
• Assess the entire supply chain from supplier
relationships to internal operations to the market
place, including customers, competitors and
industry as a whole.
IS THE SUPPLY CHAIN WORKING?
• Does our manufacturing strategy increase product
line flexibility while continuing to drive down
overall production costs?
• When was the last time we measured lost sales to
• Do we have an efficient system to get POS data
• Are we testing our products with end customers?
Do we use the resulting data to adjust our
forecasting and supply positions?
• Is the ratio of returned orders to sales
The New Model of Relationships
• Hard bargaining vs shared destiny
• Exit vs Voice
• Arms length relations vs Involving dealers and
suppliers in product development
• Piling up vs Replenishing dealer inventory more
• In short working together as partners to cut
costs, boost efficiencies, innovate and share
Adversarial vs partnerships
Short term vs long term contracts
Large vs small order quantity
Full truck load vs small parcels
Inspection vs no inspection
• Written order vs understanding
• Many vs few suppliers
• Design and then invite quote from
vendor vs involving vendor in
• Bargaining, holding cards close to chest
vs Shared destiny, transparency
• Segmentation of customers based on service
• Customization of logistics network
• Listen to signals of market demand and plan
• Differentiate product close to the customer
• Source strategically
• Develop a supply chain wide technology
• Accept channel spanning performance
• The Bullwhip Phenomenon
• Volatility amplification along the network
• Increase in demand variability as we move
upstream away from the market
• Mainly because of lack of communication and
• Delays in information and material flows
• Bullwhip effect occurs because of various
• Order Batching- Accumulate orders
• Shortage gaming- Ask for more than what is
• Demand forecast updating
Important points to keep in mind
• Segment customers based on service needs.
• Modify the supply chain to meet these service
• Customize the logistics network.
• Develop forecasts collaboratively involving every
link of the supply chain.
• Locate the leverage point where the product is
unalterably configured to meet a single
• Delay product differentiation till the last possible
• Assess options such as modularized design
or modification of manufacturing processes
that can increase flexibility.
• Cultivate warm relationships with suppliers.
• Efficient supply chain management has to be
accompanied by a technology strategy.

“ Today, assembly is the easy part. The hard part
is managing your suppliers and the flow of
parts.“ Good supply chain management strips
away time and cost from product delivery cycles.
Our customers have become more fashion
driven, working with six or seven seasons a year
instead of just two or three. Once you move to
shorter life cycles, the problem of obsolete
inventory increases dramatically. With customer
tastes changing rapidly and markets segmenting
into narrow niches, it’s not just fashion products
that are becoming increasingly time sensitive.”
