The Supply Chain Section 1 Version 2.1 1
1 The Supply Chain This section will discuss the early beginnings of supply chain and
the concepts of supply chain management.
1.1 Learning Outcomes On completion of this element, you should be able to:
Make an outline representation of an organisations supply chain and
make comparisons with similar and dissimilar types of organisation.
Distinguish between the types and directions of the flows in a supply
chain
Assess the main strength and weaknesses of an organisations supply
chain and the extent to which it provides competitive advantage for a
business.
1.2 Theoretical Foundation of Supply Chain Management
Firms can no longer effectively compete in isolation of their suppliers and
other entities in the supply chain. Interest in the concept of supply chain
management has steadily increased since the 1980s, when companies
saw the benefits of collaborative relationships within and beyond their own
organisation. The history of supply chain initiative can be traced to early
beginnings in the textile industry with quick response (QR) program and
later to efficient consumer response (ECR) in the grocery industry. More
recently, companies across many industries have begun to look at the
entire supply chain process.
The phrase Supply Chain Management was first coined in the early
1980s to describe the range of activities co-ordinated by an organisation to
produce and manage supplies. Traditionally, the term referred to an
internal focus bounded by a single organisation and how they sourced and
procured supplies managed their internal inventory and moved goods onto
their customers.
2 The Supply Chain Section 1 Version 2.1
Owing to intense competition in the textile and apparel industry world-
wide, the traditional supply chain resulted in major losses to the industry
due to financing the inventory and lack of the right product in the right
place at the right time. The original focus was therefore extended beyond
the internal management of the chain. Companies started to acknowledge
that the reality in managing supplies meant that supply chains extended
beyond the purchasing organisation and into their suppliers and suppliers
supplier. The contemporary supply chain is a term now commonly used by
logistics professionals, which encompasses every effort involved in
producing and delivering a final product, from the suppliers supply to the
customers customer.
1.3 Mapping Supply Chain Processes The question you must ask yourself is how do I understand, manage and
improve my organisations supply chains? Before supply chain
practitioners can effectively manage and improve their logistics and supply
chain processes, they must understand it. One way to improve
understanding is by developing graphic representations of the
organisational links that make up the supply chain.
Mapping a Supply Chain Serves Several Purposes:
It creates a common understanding of the participants in the supply
chain: the firms, the processes, who perform the various activities
and the results.
It defines the points of linkages and where they integrate.
It provides the baseline against which to measure the impact of
improvement efforts. Ways of identifying areas of improvement:
o Identify the major supply chain players, using a technique called relationship mapping
o Construct a process map that shows all the players and their
major activities.

Supply Chain Relationship Mapping A relationship map is a high-level map that shows the major organisational
entities involved in a supply chain and how they are connected to one
another through physical, informational and monetary flows. For example,
mapping is the first step that a manufacturer might take to identify the
various people, functional areas, and even outside organisations involved
in the activities and processes that deliver orders to the customer. The
overall objective of supply chain relationships mapping is to identify the
pattern of flows between participants.
Besides the apparel and grocery industry initiatives, other early
manufacturers who made efforts to improve their supply chain
performance include: Hewlett-Packard, Whirlpool, Wal-Mart, West Co.,
Becton Dickinson, Baxter, Georgia-Pacific Corp. and automotive Original
Equipment Manufacturer (OEM)
Source and procure inputs
Materials and labour
Transform Marketing and sales
Distribution Customer/ Service
4 The Supply Chain Section 1 Version 2.1
Task 1.1
Identify an organisation of your choice and show diagrammatically its supply chain.
What reasons led to the expansion of supply chain concept beyond the textile industry?
This example shows a simplified relationship map. It can be observed that there are not direct flows of demand forecasts between the automotive Original Equipment Manufacturer (OEM) and the Tier 2 firms. As a result, the Tier 2 firms were completely dependent on the Tier 1 supplier for any information regarding changes in demand at the OEMs assembly plant. This provided a place to begin looking for ways to improve information sharing in the supply chain.

1.4 Supply Chain Management in its Context Supply chain management as a subject area in the field of management,
since its evolution in the mid-1980s, has not yet been conceptually well
understood due to its multi-disciplinary nature. The view of the few early
proponents of supply chain management is that the subject emerged from
similar terms such as:
Network sourcing
Supply pipeline management
Value chain management
Value stream collaboration
Material and logistics management
Strategic sourcing management
Distribution channel management
Relationship development
Partnership sourcing
Supply network design
Vertical disintegration
Time-based strategy
Customer first
Industry groups have been working together to improve the integrative
processes of the subject and accelerate the benefits available through
successful implementation. The activities, processes and relationships,
which fall under the supply chain label, are central to industrial modernity.
The details of life for all of us are deeply impacted by supply chain
activities. At the global level, the material well-being of people in one part
of the world and the parallel poverty in the other part are closely
intertwined by complex networks of global production and distribution. The
flow of goods through the supply chain is the life-blood of the modern
society. It can be argued therefore, that the developments insupply chain
practice do not spring from nowhere in particular, but arise from a complex
nexus of social developments.
6 The Supply Chain Section 1 Version 2.1
1.5 Institutional Definitions
The American Production and Inventory Control Society (APICS) dictionary describes the
supply chain as:
the processes from the initial raw materials to the ultimate consumption of
the finished product linking across supplier-user companies.
The Supply Chain Council Views the supply chain as:
a term used by logistics professionals that encompasses every effort involved in production and delivering a final product, from the suppliers
supplier to the customers customer. Four basic processes plan, source, make, deliver - broadly define these efforts, which include managing supply and demand, sourcing raw materials and parts, manufacturing and
assembly, warehousing and inventory tracking, order entry and order management, distribution across all channels, and delivery to the
customer.
1.6 Other Definitions The following are views of individual supply chain scholars
Jones and Riley (1985) described the supply chain as an integrative approach to dealing with the planning and control of the materials flow from suppliers to end-users.
Christopher (1992) defined the supply chain as: a network of organisations that are involved through upstream and downstream linkages in the different processes and
activities that produced value in the form of products and services in the hands of the
ultimate customers.
New and Payne (1995) described supply chain management as the chain linking each element of the manufacturing and supply process, from raw material through to the end
user, encompassing several organisational boundaries. Its primary focus was the efficient
physical distribution of final products from the manufacturer to the end user in an attempt
to replace inventory with information.
The Supply Chain Section 1 Version 2.1 7
Harland (1996) said supply chain management is managing activities and relationships (1) internally within an organisation, (2) with immediate suppliers, (3) with first and
second-tier suppliers and customers along the supply chain, and (4) with the entire
supply chain.
Hobsons (1997) view of supply chain is more expanded to include recycling and re-use. He said: Supply chain is about organising the entire chain from purchasing the raw
materials through to the point where the end product is used or consumed. It involves
ensuring that the right product is available in the right quantity in the right condition in the
right place at the right time in its widest sense, it includes the disposal and possible
recycling of waste, and even extends to after-sales maintenance and the replacement of
parts.
Lowson et al (1999) viewed the supply as the management of the entire chain of activity from raw material supply to final consumer in order to minimise the time taken to perform
each activity, eliminate waste and offer an optimal response by maximising value.
Adewole (2005) defined supply chain as a group of interdependent companies collaborating together within a network of relationships to manage the movement of
materials, part-finished and finished goods as well as services, including all transactions
and shared information, along a customer-focused value system in order to realise
superior customer benefits at a competitive cost.
You will note that each of the definitions above identifies five key
processes Plan, Source, Make, Deliver, and Return. You will note that the five key processes indicate the role of logistics in the supply chain. Let
us use the Supply-Chain Operation Reference (SCOR) Model to examine these five processes more closely.
8 The Supply Chain Section 1 Version 2.1
Fig. 1.2 Five Processes in the Supply-Chain Operations Reference (SCOR) Model
SCOR Process
Definitions
Plan
Processes that balance aggregate demand and supply to develop a course of action which best meets sourcing, production and delivery requirements
Source
Processes that produce goods and services to meet planned or actual demand
Make
Processes that transform products to a finished state to meet planned or actual demand.
Deliver
Processes that provide finished goods and services to meet planned or actual demand, typically including order management, transportation management, and distribution management.
Return
Processes associated with returning or receiving returned products for any reason. These processes extend into post-delivery customer support.
We can argue that logistics and supply chain management have important
roles to play in sourcing, making, delivery and recall of products. Supply
chain management is the single most important strategy for ensuring
success in an industry that is experiencing intense competitive pressures,
and the most pressing technological investments for facilitating supply
chain superiority involve software associated with the logistical activity of
order fulfilment.
Modern business strategists suggest that company-versus-company
competition will be superseded in the twenty-first century by supply-chain-
versus-supply-chain competition, particularly with companies having single
sourcing relationships. It could however be noted that a more realistic
The Supply Chain Section 1 Version 2.1 9
perspective would be that individual members of a supply chain will
compete based on the relevant capabilities of their supply network, with a
particular emphasis on immediately adjacent suppliers or customers.
Example of supply chain vs. supply chain relationships, where individual companies compete using their relevant capabilities:
Bose Corporation (A manufacturer of stereo equipment) developed a supplier integration program known as JIT, facilitated by Radio Frequency
Identification (RFID) technology. The facility allowed various suppliers to
have in-plant offices at Bose. This helped them to personally interact with
other suppliers and Bose Personnel on a daily basis. The suppliers
employees stationed at Bose have the authority to place purchasing
orders from Bose for their employers goods (rather than having the
purchase orders placed by Bose employees).
Task 1.2
The Supply Chain Operations Reference (SCOR) model examines five key processes of Plan, Source, Make, Deliver and return. Demonstrate in full details how these processes apply to your organisations logistics and supply chain activities. You may use any organisation that you are familiar with.
1.7 The Structure of Supply Chain Organisations historically structured themselves into functions such as
purchasing, production and distribution, marketing and selling. These
functions work together simultaneously and manage the different parts of
the organisation to achieve set goals. As business networks have
10 The Supply Chain Section 1 Version 2.1
developed and become more complex, the boundaries of organisations
have become less detached and somewhat blurred. It can be suggested
that these blurred boundaries have meant that individual organisations are
no longer in competition, but rather supply chains, comprising of
participating organisations are competing against other supply chains.
Organisations involved in a supply chain are linked together through
physical flows of materials and products, information flows and monetary
flows. These flows go both up and down the chain. A simple supply chain
structure will comprise firms that are positioned upstream and whose inputs feed into supply pipeline, whilst those firms who take the finished
product and move them to the final consumer are considered
downstream.
Upstream: A term used to describe
activities or firms that are
positioned earlier in the
supply chain relative to
some other activity or firm
of interest.
Examples of upstream firms:
Cotton growing firms supplying cotton
materials to fabric mills.
Sheep farmer supplying hides and skins
for the production of leather and leather
products
Corn harvesting takes place upstream of
cereal processing, while cereal
processing takes place upstream of
cereal packaging.
Downstream: A term used to describe
activities or firms that are
positioned later in the
supply chain relative to
some other activity or firm
of interest.
Examples of downstream firms:
Garment sewing, wholesale and retail
shops take place downstream the
clothing supply chains.
The Brewery and Wine, Beer and Spirits
(WBS) bars and pubs take place
downstream the WBS supply chains.

Fig. 1.3 An Integrated Supply Chain Process
1.8 Managing the Supply Chain Managing the supply chain has become an issue since the 1990s because
few companies continued to be vertically integrated. Companies have
become more specialised (fig 1.3) and search for suppliers who can
provide low cost, quality materials rather than own their source of supply.
There are three critical paths for supply chain successes for companies:
Upstream
Procurement
Manufacturing
Replenishment
Customer
Consumption
Supplier
sourcing
Manufacturer
Distributor
Retailer
Customer
Consumer-end user
Downstream
Information
Goods flow
Cash flows
Demand signals
12 The Supply Chain Section 1 Version 2.1
First is to manage the entire network of supply to optimise overall
performance. Organisations have realised that whenever a company deals
with another company that performs the next phase of the supply chain,
both stand to benefit from the others success.
The second reason stems from increased national and international
competition. Customers have multiple sources from which to choose to
satisfy their demand. Customers buying habits are constantly changing,
and competitors, wherever they are located in the global village, are
continually adding and deleting products. Increased and constantly
changing demand make sure that the company will have the wrong
inventory. Companies are therefore adopting a new approach to managing
their inventory. Previously, companies distribution strategies focused on
maintaining inventory at various locations throughout the supply chain.
Today, the dynamics of the modern marketplace has made holding
inventory a risky and potentially unprofitable business. It has become
crucial that products are strategically located throughout the distribution
channel for maximum customer accessibility at a minimum cost.
The third critical path is a realisation by companies that maximising
performance of one department or function may lead to less than optimal
performance for the whole company. Companies must look across the
entire value chain in their supply pipeline to gauge the impact of decisions
in any one area, as an error in one link in the supply chain will impact on
all other links in the same chain. For example, purchasing may negotiate a
lower price on a component and receive a favourable purchase price
variance, but the cost to produce the finished product may go up due to
inefficiencies in the plant. This in turn may have a negative impact on price
competition at the retail outlet.
Supply chain management is seen as a technique which can make a
considerable contribution to the economics of business development.
Supply chain management has taken on different meanings in different
The Supply Chain Section 1 Version 2.1 13
industries. The development of increasingly close relationships between
customers and suppliers encompasses approaches including:
Development of long term relationships with suppliers
Greater and earlier involvement of suppliers in product technology
Development of mutual contractual and competence trust
Supplier associations
Benchmarking
Common supplier assessment schemes
1.9 Supply Chain Network The core of logistics and supply chain is hinged on creating and
maintaining a network of relationships both outside as well as inside the
organisation. A network consists of nodes, which represent the business
or actors, such as suppliers, producers, customers and service providers.
The links between the nodes represent relationships. Relationships
between actors are like bridges as they give one actor access to the
resources and competences of another.

14 The Supply Chain Section 1 Version 2.1
In business settings, network relationships between firms are of
paramount interest. An understanding of the concepts of supply chain
relationships and the specific processes and activities occurring among
the networks of trading partners in the supply pipeline is closely
associated to the nature of business networks. The functions of business
relationships can be characterised to three essential components: actors,
resources and activities.
Primary functions of the relationships corresponding to activities,
resources and actors are efficiency through interlinking activities, which
are mutually based on the self-interest of actors. Activities performed by
two actors, through their relationship, can be adapted to each other so that
their combined efficiency is improved, such as in just-in-time exchange. By
working together, the two actors will learn that by co-operating, they raise
the benefits that each receives.
Secondary functions are caused by the existence of connections between
relationships. This relates to chains of activities involving more than two
firms. Resources developed in this type of relationships are important to
those engaged in the relationship, as they may have implications for
resources of parties engaged in connected relationships. Thus innovations
developed as a result of interaction in several relationships may support
each other. By getting involved in a network, a focal firm may have its
views shaped by, and shape the views of, its partners partners.
It can therefore be said that a network is not a world of individual and
isolated transactions. Rather, it consists of a series of direct and indirect
ties from one actor to a collection of others. It is a closed set of actors
forming the largest set of interconnections possible.
Ford et al defined a network relationship as a companys portfolio of
relationships and the rights and obligations that go with it. Network
structures allow organisations to bring resources together on a long-term
The Supply Chain Section 1 Version 2.1 15
basis to reduce costs. This is why most growing organisations are
increasingly turning to global networks as a means of gaining access to
low-cost overseas inputs. Networks relate to all aspects of the supply
chain, including marketing, logistics and distribution.

Many researchers within supply chain management subject areas have
claimed that a general paradigm shift is taking place within marketing,
focusing on relationship management instead of managing separate
discrete transactional exchanges with business counterparts.

1.10 Managing the Supply Chain Networks Supply chain managers should evaluate, maintain and review the
companys network positions by consolidating some of the elements of
their current positions. For example, a company may choose to maintain
its existing distribution relationships through a wholesaler. Alternatively,
firms may want to create new elements by developing new supply chain
relationships to increase the range of their offerings.
Supply chain managers should carry out an overall assessment of the
companys dealings with the surrounding network in order to determine to
what extent it can influence those in the same network to achieve their
business ends without major hindrance to others in the network. An
example is Marks & Spencer, who insist that its suppliers should produce
to its own design and determine where to source fabrics from, and how
suppliers should deliver.
1.11 Reasons for Slow Growth of Integrated Supply Chain Management
Despite the acceptance of the concept of integrating and managing the
supply chain, growth of integrated supply chain management has been
slow. Reasons for the slow growth include the following:
Lack of guidelines for creating alliances with supply chain partners.
Failure to develop measures for monitoring alliances.
Supply Chain Networks
The ability of a firm to manage its supply chain networks may itself be considered a
core competency. This is certainly the case for Dell Computer Corporation, which
practices what Michael Dell calls virtual integration. While not all organisations are
as dependent on their supply chain partners as Dell is, current industry trends suggest
that more organisations are focusing on developing only a few competencies and
outsourcing everything else. This puts a premium on an organisations ability to select
good partners and coordinate the flow of information and material between partners.
The Supply Chain Section 1 Version 2.1 17
Inability to broaden the supply chain vision beyond procurement or
product distribution to encompass larger business processes.
Inability to integrate the companys internal procedures.
Lack of trust inside and outside a company.
Organisational resistance to the concept.
Lack of buy-in by top managers
Lack of integrated information systems and electronic commerce
linking firms.
Task 1.3
1.12 Global Supply Chain While the supply chains at the domestic level focus on performing value-added services in a relatively controlled environment, global supply chains
combine all the domestic purchasing and supply as well as logistics
requirements when dealing with uncertainties associated with cross border
factors such as distance, language and culture, international regulations,
payment systems and other documentations.
Supply chain managers who operate in the international arena are
required to develop a wide variety of capabilities and expertise to deal with
A logistics and supply chain pipeline is comprised of upstream
and downstream linkages. With an example of a chocolate bar, identify the organisations that might be in the upstream and those that are in the downstream of its supply chain.
Supply-chain-versus-supply-chain competition will soon take over from company-versus-company competition. Discuss this proposition
18 The Supply Chain Section 1 Version 2.1
these factors, as global operations have increased cross border supply
chains cost and complexity.
The estimated supply chain cost for 2000 in industrialised nations
exceeded $2 trillion or 11.7% of combined gross domestic product (GDP).
In the UK alone, the global logistics costs for the same year were
estimated to be $1.05 billion, representing about 12.2% of the UK GDP.
Supply chain complexity arises due to (a) increases in uncertainty as a result of greater distances, longer lead-times and a decrease in market
knowledge, (b) decreases in capability and control due to extensive use of
intermediaries and government interventions such as customs
requirements and trade restrictions.
Logistics and supply chain management professionals must be aware that
in spite of the complexities, globalisation cannot be avoided. Managers
must resolve these concerns and complications that are causing barriers
to borderless logistics and supply chain activities.
Barriers to Global Supply Chain Management We will now take a look at the possible barriers to supply chain operations
as companys trade around the world.
Pricing and currency difficulties International pricing is strongly influenced by exchange rates. Prices may rise due to sudden increased
cost incurred by the supplier while the local retailers will only sell at a price
above the rate of exchange in order to ensure profitability.
Apart from fluctuations in exchange rates and difficult methods of
payment, tariffs are imposed to protect domestic industries by increasing
prices on imported goods. This has the following implications on
international trade:
The Supply Chain Section 1 Version 2.1 19
a) they are additional cost elements that must be considered when
evaluating foreign sources of supply
b) they are political; subject to quick change as government policy
alters.
Entry restrictions - these include legal and physical barriers to restrict market access to overseas importers. Physical barriers - European
practice on local presence requiring market-based manufacturing or
distribution facilities to be established prior to market access. Legal
difficulties what trade restrictions on imports or exports. What trade
restrictions are imposed on new entrants? For example the Japanese
practice where local retailers 'vote' to accept new retailers, particularly
foreign ones.
Barriers arising from poor weather, material-handling equipment, cargo transfer, warehouse facilities, port facilities, dock strikes, poor
communication systems and custom actions.
Differences in global transportation equipment such as vehicle dimensions, capacity, weight, and rail gauge.
Documentation and poor information availability - Little co-ordinated information is available on import and documentation requirements. Terms
of trade regarding bills of lading, certificate of origin, customs entry forms,
shipment cancellations, deliveries and delays information are taking longer
to transmit.
Typical requirements differ by government and even by specific case. In
countries where documentation has to be completed and processed prior
to shipment, goods may be delayed or impounded if the documentation is
not flawless. There is limited information available on market size,
demographics, and competitive trends in the market. Efficient and effective
20 The Supply Chain Section 1 Version 2.1
application of appropriate information and communication technologies
has made most of these problems a thing of the past.
Institutional Infrastructure This results from major differences in how facilitating intermediaries such as banks, insurance firms, legal
counsellors, and transportation carriers operate.
Services that are taken for granted in one country, are administered
differently in another country, e.g. banking or insurance facilities that are
taken seriously in Britain may just be in their infant stage in, say, South
Korea or Indonesia.
For instance, payment procedures take two or three weeks in Eastern
Europe, or Morocco, whereas in the UK it takes less time for payment
receipts to be processed. Such delays significantly complicate order
processing and increase financial and inventory risks.
Forces Driving Global Supply Chain Relationships New relationships development in the supply chain have changed from the
old adversarial, selfish approach, where managers focused on reducing
procurement cost and manufacturing expense within their own enterprise
and ignored the expenses incurred by other chain members when making
product sourcing or manufacturing decisions. There is now a more open
and collaborative approach, with better transportation at lower cost, better
global communication links that enable trading partners to know more
about each other's businesses and co-operate to remove bottlenecks in
the chain through integration of business functions, joint planning and joint
investment for a more efficient and effective supply chain management.
Let us look at the following four factors as they influence and facilitate
international supply chains.
The Supply Chain Section 1 Version 2.1 21
Economic growth - The search for business growth and maximised market opportunities, and the desire for economies of scale and
profitability are fundamental forces driving supply chain managers to
establish new relationships with trading partners around the world. Most
companies now seek global supply chain competition by collaborating with
manufacturers and suppliers in developing countries as a direct means of
increasing revenue and profit. For example, the UK clothing retailers such
as Marks and Spencer, the Arcadia group and other high street retailers
source garments from the Asiatic countries, where cost of production is
lower compared to the UK production.
Consequently firms are more willing to develop alliances with global
suppliers that could provide expertise and quality service at a reasonable
cost for activities such as international freight consolidating and
forwarding, international transportation, cross border documentation,
quality control and facility operations.
Trade liberalisation and the removal of trade restrictions in the movement of capital, materials and intermediate components - Each countrys political borders have traditionally served as a barrier to trade.
Government restrictions and requirements cause supply chain and
logistics problems. New trends in cross border trading have necessitated
the removal of country and regional barriers and facilitate global supply
chain. Countries are entering into trade treaties and agreements that
promote regional trade and protect trading partners from outside
competition. Examples of such agreements are the European Community
(EC 92), the North American Free Trade Agreement (NAFTA) the Group
of Eight (G8), the Multi-Fibre Agreement concluded in Uruguay under the
General Agreement on Tariff and Trade among many others. These
multilateral agreements help global corporations to ship semi-
manufactured products between their own factories or from suppliers to
assembly plants and distribution centres around the world.
22 The Supply Chain Section 1 Version 2.1
Deregulation and the role of International Monetary Fund (IMF) - Many countries of the world tend to embrace the market-based reforms and
integration as proposed by the IMF. Inter-governmental arrangement and
co-operation in trade regulations, procedures in finance, transportation,
and service tend to yield improved global market service while
simultaneously reducing tensions in the supply chains, a net result of
which should favour international trade.
The newly industrialising nations - The emergence of new major trading nations from newly developed (developing) economies in China, South-
East Asia and in Latin America is facilitating further development of global
supply chains.
Increasing Technology - Technology explosion is a major force driving the global market. Global market awareness through powerful information
technology stimulates a convergence of global needs and preferences.
The international consumers are now exposed to foreign products more
than ever before.
Consumers all over the world desire better quality product at minimum
price possible. For example the demand for blue jeans, sportswear and
athletic shoes has increased in Eastern Europe, Asia and Africa.
Computer hardware and software technologies in manufacturing and
communication network such as material requirement planning (MRP 1),
manufacturing resource planning (MRP II), enterprise resource planning
(ERP), electronic data interchange (EDI), E-mail and Internet
technologies, Cable News Network (CNN), radio frequency identification
(RFID), multi-media mobile phones, and other satellite communications
promote a variety of products and stimulate global demands.
Information and communication technologies (ICT) have made easier
international supply chain negotiations and transactions and speed up
activities in the logistics supply pipelines. Prior to the application of
The Supply Chain Section 1 Version 2.1 23
information technology, trade documentations were traditionally hard copy
papers that required extensive time to transfer upstream the supply chain,
and often contained many errors. For example, in the clothing industry, the
performance cycles from order commitment to order receipt of garment in
the UK were 8-12 weeks from Far East Asia, 6-8 weeks from neighbouring
European countries and 4-6 weeks from within the UK. But with the use of
enhanced ICT that speeds up order requirements, communication,
production scheduling, shipment scheduling and custom clearance, the
performance cycles have been drastically reduced to less than half.
Global Supply Chain Strategy Given the barriers and the opportunities inherent in the operation of global
supply chains, practitioners must develop workable strategies for
conducting their businesses.
As a logistics and supply chain professional you will need to:
Identify and develop your organisations core competences that
will give access to the global markets;
Participate in global supply chain networks;
Understand and operate efficient logistics and supply chain
configuration (design) of value-adding activities;
Engage in global supply chain co-ordination and integration of
activities;
Relate to local responsiveness where required;
Participate in efficient, effective and timely information sharing,
assisted by the application of information and communication
technologies

Task 1.4
1.13 The Relationship of Logistics to Supply Chain Management
A number of definitions of supply chain have been given in this section.
Having gained a clear understanding of the supply chain concept, we will
now look at a few definitions of logistics and examine its relationship to
supply chain management.
The Council of Logistics Management (CLM) (1998) defines logistics as:
the process of planning, implementing, and controlling the efficient, effective flow and storage of goods, services and related information from the point of origin to the point of consumption for the purpose of conforming to customer requirements. Note that this definition includes inbound, outbound, internal and external movements, and return of materials for environmental purposes.
With increased interest in supply chain management, several authors have
discussed the differences between this newer concept, supply chain
management, and logistics. Cooper et al. (1997) stated that a
contemporary understanding of supply chain management is not
appreciably different from the understanding of integrated logistics
management. However these same authors suggested that a broader
understanding of supply chain management was emerging, one that
includes the integration of business processes from end use through

original suppliers that provides products, services, and information that
add value for customers. Supply chain management is not just another
name for logistics, it includes elements that are not typically included in a
definition of logistics, such as information systems integration and
coordination of planning and control activities.
Giunipero and Brand (1996) viewed that in its broadest context supply
chain management is a strategic management tool used to enhance
overall customer satisfaction that is intended to improve a firms
competitiveness and profitability. Johnson and Wood (1996) concluded
that supply chain management is somewhat larger than logistics.
Lummus et al (2001) conducted a survey of manufacturers, retailers and
third party logistics providers in the United States. The table below shows
their conclusions on the relationship of logistics to supply chain
management as described by industry practitioner.
Types of firms How are the areas related?
Manufacturers
Logistics is a subset of the overall supply chain
process. In order to have an efficient chain, logistics processes must be well defined and cost effective.
Logistics works to transport material through the supply chain as cost effectively as possible.
Retailers
Supply chain management and logistics are
intertwined as can be noted from job descriptions. Good communications must exist between the two areas and each must have strong support from the others upper management
Supply chain management has three functions: a) develop strategic logistics capabilities, b) guide the planning and alignment of the retail supply chain, and c) integrate logistics into retail procurement processes.
26 The Supply Chain Section 1 Version 2.1
Third-party logistics
Supply chain involves multiple companies for a
complete process and logistics is the complete applicable portion of the process within the company
1.15 Logistics and Supply Chain: Structure and Tiering
The concepts of logistics and supply chain suggest a series of processes
linked together to form a chain. Let us look at a typical logistics and supply
chain processes for a retail company.

national distribution centre (NDC), where it is stored and matured for nine
months, when it is then be shipped in response to an order from the
retailer. The cheese is transported first to the retailers regional distribution
centre (RDC), from where it is finally transported to the retail store. As the
material flows from upstream suppliers to downstream customers,
information flows from downstream customers to upstream suppliers.
Logistics is clearly involved in the movement of both materials and
information to and from sides of the supply chain. Through a logistical
approach supply chains are able to harmonise the physical and
information flows in an integrated manner and the various trade-offs
obtained.
Task 1.5
1.15 Procurement, Logistics and the Supply Chain We have defined the terms logistics and supply chain in our previous
discussions. Before we engage in the discourse of how procurement,
logistics and supply chains work together, it is important to define the term
procurement.
What is Procurement? Procurement is the process undertaken by the organisational unit which,
either as a function or as part of an integrated supply chain, is responsible
both for procuring supplies of the right quality, quantity, time and price and

Discuss how supply chain integration can benefit logistics and the firm as whole.
28 The Supply Chain Section 1 Version 2.1
the management of the suppliers, thereby contributing to the competitive
advantage of the enterprise and the achievement of corporate strategy.
Relationship of Procurement to Supply Chain Management? Procurement functions now recognise a need for joint cooperation with
other parties in the supply chain to achieve:
Cost reduction or improvement
Improved material delivery
Shorter cycle time, including product development cycle times
Access to product and process technology
Quality improvement
From a strategic point of view, the procurement mission has been primarily
a support function to other logistics and operations. Purchasing must
therefore be aware of the components and services needed by operations
and logistics as they plan to assemble a product or deliver a service.
Because purchasing is responsible for sourcing the components to
support an operations plans, purchasing managers must work with
schedulers to coordinate the delivery of materials to the production site.
The increasing importance of supply chain management is forcing
organisations to rethink their purchasing and supply chain strategies.
Despite the apparent complexity of managing supply chains, some
organisations are thriving and exploiting their supply chains for competitive
advantage. As companies strive to increase customer value by improving
performance while simultaneously reducing costs, many companies are
turning their attention to purchasing and distribution management the
part of supply chain management that focuses on the management of
inbound goods and services into a firm.
The Supply Chain Section 1 Version 2.1 29
Supply Chain Management in the food production from the farm to the consumer
Simple supply chains pull materials directly from their origin, process
them, package them, and ship them to consumers. A good example of a
simple supply chain involves cereal producers. A cereal company
purchases the grain from a farmer and processes it into cereal. The cereal
company also purchases the paperboard from a paper manufacturer, who
purchases semi-finished label stock to make the labels. The cereal is then
packaged and sent to a distributor, who in turn ships the material to a
grocer, who then sells it to an end customer.

automobile industry have changed significantly. Three changes are
noteworthy. The first is supplier development and participation in product
development. The suppliers who formerly worked to assemblers design
have moved towards offering their own design solutions by taking up more
design responsibilities from assemblers. The second is that there has
been a shift from individual components towards the supply of complete
functions such as systems, sub-assemblies and module. This means that
a first-tier supplier becomes responsible both for the assembly of parts into
complete units such as dashboards, seats, and cockpit and for the
management of the second-tier suppliers (See figure 1.8 below). The third
is that assemblers are standardising their platforms across their
constituent companies.

These changes have led to significant restructuring in the component
industry. Several trends have been identified. One of them is the
emergence of a reduction in the number of direct suppliers in order to

maximise the limited time and resources available. Resourcing and tiering
activities are helping the component industry to concentrate in companies
that can design and provide systems and subassemblies across many
different markets. For example new global companies such as Autoliv
MNC have been created through the fusion of smaller companies. Major
component manufacturers have encouraged the development of strategic
alliances in order to deliver more extensive component systems or
develop new products. These changes have had considerable effects in
the emerging markets.
1.16 The Value Chain A value chain is a linked set of value-creating activities beginning with
basic raw materials coming from suppliers, moving on to a series of value-
added activities involved in producing and marketing a product or service,
and ending with distributors getting the final goods into the hands of the
ultimate consumer. The focus of a typical value chain analysis is to
examine the organisation in the context of the overall chain of value-
creating activities. In order to identify a companys core competence and
special capabilities, it is often essential to understand the different
capabilities available within the company.
Porters (1985) value chain separates the internal activities of a firm into a
sequential chain. These activities are classified as primary and supportive
functions. (See fig 1.9) According to the Value Chain analysis, the
companys primary activity is broken down into five different categories:
inbound logistics, operation (work-in-progress), outbound logistics,
marketing and selling and customer service. The value chain represents
the actual manufacturing of a product or delivery of a service that the
company performs. The chain of functions starts with the supply of raw
material and continues on through parts and components production,
manufacturing and assembly, wholesale distribution, and retailing to the
ultimate end user of the product or service.
32 The Supply Chain Section 1 Version 2.1
The supportive functions in a firm are divided into four different categories:
general administration, research and development, human resource
management and procurement. These activities support the above primary
activities creating the fundamental structure and internal infrastructure
needed within the company in order to produce goods and services.
Fig. 1.9 The Value Chain
Source: Adapted from Kotler (1999)
The Primary Activities Inbound logistics: activities concerning receiving, unloading, unpacking, storing, handling and distribution inputs as well as controlling inventories.
Operations: transformation of the inputs into the products that are to be provided. Processes involving manufacturing, assembly, packaging,
maintenance of equipment, designing etc.
Outbound logistics: activities linked to physical distribution of the products to buyers. In retail it includes checkout operations.

Marketing and selling: creating awareness of the product or service in the buyers, persuading them to buy, making the product available in a
number of locations to facilitate purchasing.
Service: after sales customer service including installation, training, repair and spare parts availability.
The Support Activities Procurement: obtaining purchased inputs of all kinds.
Human Resource Management: recruiting, training, developing and organising of personnel.
Research & Development/Technology: basic research and the design and development of both products and processes.
Firm Infrastructure: managerial process and all general management activities such as planning and control, quality management, obtaining and
allocating funds, the work of the legal department and dealing with
governments.
The value chain of most industries can be split into two segments,
upstream and downstream halves. In the petroleum industry such as
Texaco, for example, upstream refers to oil exploitation, drilling, and
moving the crude oil to the refinery, whereas downstream refers to refining
the oil plus the transporting and marketing of gasoline and refined oil to
distributors and gas station retailers.

Source: Porth (2002), Strategic Management In analysing the value chain of a product, the organisation, usually has an
area of key expertise where its primary activities lie. An organisations
centre of gravity is that part of the chain that is most important to the
company and the point where its greatest expertise and capabilities, its
core competencies, lie.
The systematic examination of the organisations value activities can lead
to a better understanding of the firms strengths and weaknesses. It can
also help to negotiate more favourable prices with suppliers. The value
chain helps to find ways to expedite just-in-time deliveries, inventory costs,
warehousing, shipping and production scheduling costs. It will help to
eliminate cost producing activities by using technology and e-commerce. It
helps to relocate manufacturing activities to geographic areas where they
can be performed more cheaply (economies of scale through outsourcing).
It also helps to implement the use of best practice throughout the
organisation, particularly high cost activities.

Task 1.6
1.17 Customer Service Markets are increasingly becoming sophisticated with customers and
consumers demanding in a competitive environment that is more volatile
and less predictable (Christopher and Peck 2003).
Todays customer is much more sophisticated than before and this is a
radical change to markets that are now characterised by:-
Sophisticated and experienced customers Perceived equality of product and service functionality Transition from a sellers market to a buyers market Price competition Time compression
Consumers possess knowledge about products and services and
alternatives as a result of exposure to information through various sources
In these circumstances, organisations that will win and survive are those
that can provide goods and service within acceptable lead times, being
able to offer a range and variety of products and services with greater
reliability.
This calls for strategies for long term customer retention by redesigning
customer service objectives.
Customer service encompasses all activities between a supplier and a
buyer including all tangibles and intangibles elements.
With reference to a logistics organisation with which you are familiar, discuss how far the value chain concept is able to explain current and potential sources of competitive advantage.
36 The Supply Chain Section 1 Version 2.1
Components of customer service can be split into three elements. These
are summarised below:
1) Pre-transactional elements
Customer service policy
Accessibility
Organisation structures
System flexibility
2) Transactional elements
Order cycle times
Inventory availability
Order fill rate
Order status information
3) Post-transactional elements
Availability of spares
Call-out time
Product tracing/warranty
Customer complaints, claims
The notion is to create measures and standards that focus on customer
service levels. This area will be discussed further in section three.
Supply Chain Planning Section 2 Version 2.1 37
2 Supply Chain Planning This section will discuss the importance of the strategic planning of
supply chains and the concepts of supply chain management.
2.1 Learning Objectives: Outline how company objectives are translated into a meaningful
supply-chain strategy. Devise tactical plans to meet customer service requirements Analyse the pattern and requirements for inventory in your
organisations supply chain Devise suitable alternative supply chain solutions including
outsourcing potential.
2.2 The Purpose of Planning In discussing the nature and role of supply chain planning, it is important
to look at strategic planning from the generic perspective. To be effective,
a strategic planning system must be goal driven. The setting of objectives
is therefore a key step in the business planning process. Objective setting
can be seen to follow on from the initial stage of analysis and, in particular,
the business audit, which provided the focus. By setting objectives the
planner is attempting to provide the organisation with a sense of direction.
Objective setting also provide a basis for motivation as well as a bench-
mark against which performance and effectiveness can subsequently be
measured. The setting of objectives is thus at the very heart of supply
chain planning and is helpful for developing a good supply chain strategy.
What is Planning? Jackson (1975) viewed the planning as attempts to control the factors
which affect the outcome of decisions. He said to plan is to decide what to
do before doing it. Therefore a methodical approach can be custom built
or ready made according to the nature of the problems involved. Drucker
38 Supply Chain Planning Section 2 Version 2.1
(1959) suggested that planning is a continuous process of making present
entrepreneurial decisions systematically and with best possible knowledge
of their futurity, organising systematically the effort needed to carry out
these decisions against expectations through organised feedback.
Logistics and supply chain practitioners should participate in the process
of systematic planning, both within their own organisation and with their
trading partners. In this process many decisions are required for
successful supply chain management and these decisions can fall into
three main categories or phases. Chopra and Meindl (2006) identified
decisions during the following phases:-
Supply chain strategic or design: - these are decisions relating to how the
structure of the supply chain should be over several years. The
configuration of the chain will influence how resources are allocated; the
location and capacity of the various facilities are all strategic decisions.
Supply chain planning: - decisions in this phase relate to periods shorter
than the above, (say 3 months to a year). These decisions look at
balancing strategic restrictions and constraints with market requirements.
Planning includes decisions on which markets are to be served from which
locations.
Supply chain operations: - here the time horizon is much shorter e.g. daily,
weekly and may relate to individual order satisfaction. At this level supply
chain configuration is considered fixed and planning policies have been
laid down.
What is Strategy? There are various definitions that have been given for strategy but in
general, strategy has been referred to as a long plan of achieving a given
objective. Mintzberg (1997) offers the following highlights in his definition
of strategy: Strategic planning is a complex process, which involves taking
a view of the organisation and of the future that it is likely to encounter,
Supply Chain Planning Section 2 Version 2.1 39
and then attempting to organise the structure and resources of the
organisation accordingly.
Different authorities have defined
