The Scope of the Supply Chain
The role of manufacturing industry is to create wealth by
adding value and selling products. Common to all
manufacturing companies is the need to control the flow
of material from suppliers, through the value adding
processes and distribution channels, to customers. The
supply chain, as shown in Figure 1, is the connected series
of activities which is concerned with planning, co-
ordinating and controlling material, parts and finished
goods from suppliers to the customer. It is concerned with
two distinct flows through the organisation: material and
information. The scope of the supply chain begins with
the source of supply and ends at the point of consumption.
It extends much further than simply a concern with the
physical movement of material and is just as much
concerned with supplier management, purchasing,
materials management, manufacturing management,
facilities planning, customer service and information flow
as with transport and physical distribution.
The objective of managing the supply chain is to
synchronise the requirements of the customer with the
flow of material from suppliers in order to effect a balance
between what are often seen as the conflicting goals of
high customer service, low inventory investment and low
unit cost. The design and operation of an effective supply
chain is of fundamental importance to every company.
It is important to understand that customer service
encompasses all the points of contact between the
customer and the supplier in terms of fulfilment of orders,
and includes delivery service, pre- and post-sales services,
technical support, financial packages and so forth.
Customer service is the output from the supply system
and it results from the combined effect of all functions along
the supply chain. The activities carried out by all functions
are important in establishing a desired level of customer
service performance. They are also interdependent; if one
activity fails, the chain is disrupted, creating poor
performance and destablising the workload in other areas,
thereby jeopardising the effectiveness of the supply chain.
To provide higher service level will, without incurring an
undue burden of cost, require that all the activities along
the supply chain are in balance. To achieve the necessary
balance between cost and service involves trade-offs
through the chain (see Figure 2). For the benefit of such
trade-offs to be fully achieved it is necessary to think in
terms of a single integrated chain rather than narrow
functional areas. Unfortunately, the functional attitudes
and goals in most companies are in conflict and hinder
integration along the supply chain. The traditional approach
to managing these conflicts has been to concentrate at
the operational and planning levels and compensate for
the imbalance with excess inventory and capacity. The
results of this approach have for some companies, at best,
been frustrating and expensive, at worst, disastrous. To
resolve these conflicts effectively and turn the supply chain
into a weapon for gaining competitive advantage requires
the development of an integrated supply chain driven by
the needs of the business.

The Development of an Integrated Supply
Chain
The development of an integrated supply chain requires
the management of material flow to be viewed from three
perspectives; strategic, tactical and operational. At each
level the use of facilities, people, finance and systems must
be co-ordinated and harmonised as a whole (see Figure 3).
Strategic Perspective
While businesses often spend a lot of time and thought
on strategic issues in the area of manufacturing, finance
and marketing, the focus on supply is rarely strategic, it
tends primarily to be operational. If supply issues are
disregarded, such that the supply chain is excluded from
the strategic debate, there is imbalance, exploitable
opportunities are missed and the impact of the competitive
threat increased.
The focus at the strategic level should be to develop:
• objectives and policies for the supply chain. These
should be expressed in terms of what the supply
chain has to do well (be responsive to change,
operate at lowest cost, ensure a high level of
product availability etc) to support the needs of the
business;
• the shape of the supply chain in terms of key
facilities and their locations;
• the company's competitive package, planned by
product and market segment, detailing the balance
between product availability, service level, lead
time, technical support and after sales support;
• an outline organisation structure able to bridge
functional barriers and operate an integrated supply
chain effectively.
Tactical Perspective
The tactical perspective should focus on the means by
which the strategic objectives can be realised. It involves
translating the strategic objectives and policies into
complementary goals and objectives for each function to
provide balance to the supply chain. The functional goals
provide the drivers for achieving the balance and inventory,
capacity and service are the levers by which balance is
achieved. Additionally, the tactical dimension involves
determining the tools, approaches and resources
necessary to deliver the "do wells", in particular the most
appropriate mix of systems (MRPII, DRP, J IT etc.)
necessary to manage the supply chain and provide the
information infrastructure.
Operational Perspective
The operational perspective should be concerned with the
efficient operation of the supply chain. It focuses on the
detailed systems and procedures and ensures that
appropriate controls and performance measures are in
place. Typically, a company should measure the
performance of the supply chain in terms of inventory
investment, service level, throughput efficiency, supplier
performance and cost.
This vertical dimension linking the strategic, tactical and
operational perspectives is key to effective organisation
development because it provides a framework which
INTEGRATING THE SUPPLY CHAIN 5
precludes the need to consider centralised or decentralised
supply chain control as exclusive structures. It provides
the flexibility to centralise the strategic, decentralise the
operational where practical, and tune the tactical decision
making according to the organisational requirements of
the particular company.
Systematic Approach for the Development of
an Integrated Supply Chain Strategy
In the context of the supply chain, companies are having
to face up and respond to a number of issues, including:
• the high cost of supply chain activities (estimated
to be between five and 20 per cent of net sales
value);
• the level of inventory (typically, stock levels are
between three and five months' usage);
• poor customer service (in terms of lead time,
availability, reliability, documentation and
responsiveness);
• inter-departmental conflicts;
• goal restructuring.
If a company is to respond to these issues and develop
an integrated supply chain strategy, it must be done by
close interaction of all business areas and not on an ad
hoc basis. To ensure success a structured approach is
required. Developing an integrated supply chain strategy
can be considered as a three phase process (see Figure 4).
Phase I: Competitive Environment Evaluation
The first step is to look outward. The objective is to
develop and document the characteristics of the
marketplace. The reason for this evaluation is to focus
and direct the total strategy development effort to where
it can be applied to best effect. Too often when companies
want to evaluate the supply chain it is done either at the
whim of the individual involved or it just focuses on areas
where the company has had success in the past. This
narrow approach is invariably ineffective. The way to
evaluate operations and to develop a supply chain strategy
is to determine those areas where the marketplace
demands that a company must be competitive. Therefore,
it is necessary to evaluate the market. By doing this it
also provides a framework for the evaluation of alternative
solutions which can be developed later.
The process used to evaluate market characteristics
involves looking at and surveying vendors, customers and
competitors in order to determine the needs of the
customer and the pressures which the vendors, customers
and competitors can apply in a particular situation. In
effect, what is being identified is, "what do the customers
want?", and "how much weight do they have in the market
to get what they desire?". The output from this work is
a list for each product of the market characteristics which
can then be weighted in order of importance.
The purpose of the second step is to review and
summarise concisely the company's existing strategies.
The reason for this is not to evaluate the sophistication
or the appropriateness of particular strategies but to focus
and direct the supply chain development effort. The
purpose is simply to identify the internal constraints which
may impact on the development of a supply chain strategy.
The third step is to determine the order winning criteria,
the object being to define, prioritise and eventually weight
the customers' critical purchasing factors. To do this, it
is necessary to combine the internal and external factors
which have been identified and develop a single, prioritised
list for each product market segment, such that effort can
be concentrated on areas of importance. This approach
also provides a clear framework which can be used to
determine which techniques and strategic elements are
most important to the company.
Phase II: Supply Chain Diagnostic Review
Once the order-winning criteria have been defined, the
next step is to review the supply chain operations and to
identify those areas which offer potential for improvement.
The first step is usually to develop a cost model. This
is necessary because in many companies the traditional
cost accounting and measurement systems do not
effectively distribute the costs of the activities in the
organisations to individual products or market segments.
In fact, they are invariably not even presented in a way
which enables the costs of particular activities to be clearly
defined. The objective of this step, therefore, is to develop
a realistic method of allocating overhead costs to products,
markets and activities.
6 IJPD & MM 19,8
At the same time as developing the cost model, effort
should be directed towards identifying those activities in
the company which mostly affect and impact on the ability
to meet customers' needs. That is, identify what the
company has to "do well". The objective is to identify
those activities in the company operations which can
significantly impact on the company's ability to satisfy
customer needs. Again, allow effort to be focused only
on those activities which have an impact and provide
improvement opportunities.
The last step in Phase II is to develop a list of potential
improvement techniques for each of the opportunities
which have been identified. This list is not intended to
be a strategy or even a recommendation of improvement
techniques, but the first step towards identifying
techniques for consideration in developing a supply chain
strategy and a final implementation plan.
Phase HI: Supply Chain Development
The final phase is the development of a supply chain
strategy and tactical plan for implementing that strategy.
The objective here is to develop a strategy for the
company, based on the work done in the first two phases
which is consistent with customer desires, management
focus, market characteristics and the realities of the
organisation. This strategy should utilise fully the company
operations and competitive tools, and allow an approach
to supply chain improvements which is integrated with the
rest of the business.
The final task is to reduce the supply chain strategy to
actionable implementation plans by developing specific,
time-phased, tactical plans for implementing the strategy.
This involves organising and prioritising the list of potential
improvements, developed in an earlier task, to reflect the
strategic plans which have now been developed. The result
of this task is a set of time-phased action plans for
implementing the supply chain strategy.
Achieving an Integrated Supply Chain
Although a detailed top down approach to developing an
integrated supply chain strategy is essential, its successful
achievement is likely to be bottom up, evolving through
a number of stages (see Figure 5).
Stage 1 ("base line") is typified by the company that vests
responsibility for different activities in the supply chain
in separate, almost independent, departments. Even in
relatively small concerns the "base line" supply chain is
fragmented and characterised by:
• staged inventories caused by failure to integrate and
synchronise activities;
• independent and often incompatible control systems
and procedures covering sales, manufacturing,
planning, material control, purchasing, etc;
• organisational boundaries, whereby purchasing
might control the incoming material flow to raw
material stocks. Manufacturing and production
control would cover raw material through capacities
and in-process inventories to finished goods.
Further along the chain, sales and distribution
divide the outward supply chain and inventories.
In Stage 1, company planning is very short term — to the
point where it is almost reactive; very much based on the
quick fix, lurching from crisis to crisis.
This situation gives rise not only to inefficiencies within
the operation of the supply chain, but it puts in jeopardy
the overall effectiveness of the supply chain as well as
increasing the company's vulnerability to the effects of
changes in supply and demand patterns.
The next stage of development involves functional
integration which focuses principally on the inward flow
of goods. This level of integration is characterised by:
INTEGRATING THE SUPPLY CHAIN 7
• emphasis on cost reduction rather than
performance improvement;
• discrete business functions, each of which is
buffered by inventory;
• elements of internal trade-off between, for example,
purchase discount and the level of inventory
investment, high plant utilisation and batch sizing;
• customer service tends still to be reactive, in other
words, the customer who shouts the loudest gets
the goods.
With regard to planning and control systems, Stage 2
companies typically apply time phased planning to the
materials and manufacturing management areas using
MRP or MRPII techniques. Within the distribution
network, demand will continue to be aggregated. In effect,
orders are still being thrown over the wall to
manufacturing, such that for planning purposes the
distribution infrastructure is effectively decoupled from
manufacturing. As a result, there is poor visibility of real
customei demand which leads to inadequate planning and
generally poor performance.
8 IJPD & MM 19,8
The third stage of development recognises that there is
very little point in just focusing on the flow of goods into
the organisation unless the flow is well managed on the
way to the customer. This stage involves the integration
of those aspects of the supply chain directly under the
control of the company and embraces outward goods
management, integrating supply and demand along the
company's own chain. Internal integration is characterised
by a comprehensive integrated planning and control
system. Typically, Stage 3 companies will use DRP
systems, integrated via well-managed master schedules
to an MRPII system for materials management — using,
where practical, JIT manufacturing techniques to support
the execution of the material plan.
When a company has achieved such a level of integration,
it can truly begin to talk of synchronised demand
management — synchronising the demand from the
customer with the manufacturing plan with the flow of
material from suppliers to reap substantial benefits by
substituting information for inventory.
Stage 3 supply chains are characterised by:
• full systems visibility from distribution through to
purchasing;
• medium-term planning;
• the focus on tactical rather than strategic issues;
• an emphasis on efficiency rather than effectiveness
— ensuring what is done is done well, rather than
ensuring that the right thing is done;
• extensive use of electronic data interchange to
support the customer link and facilitate a faster
response,
• reacting to customer demand rather than
"managing" the customer.
It is not until Stage 4 that full supply chain integration is
achieved by extending the scope of integration outside the
company to embrace suppliers and customers.
The significance of this development goes beyond just
scale alone. It embodies a change of focus; away from
being product-orientated to being customer-orientated,
penetrating deep into the customer organisation to
understand the products, culture, market and organisation.
This should ensure that the company is attuned to the
customer's needs and requirements.
Integration back down the supply chain to include suppliers
also represents more than just a change of scope — it
represents a change in attitude, away from the adversarial
attitude of conflict to one of mutual support and co-
operation. Co-operation starts at the early stages of
product development and encompasses full management
involvement at all levels; the supply of high quality products
shipped direct to the line on-time; shared product, process
and specification change information; technology exchange
and design support, and above all, long-term commitment,
which usually means the elimination of multiple sourcing.
Summary
Common to all manufacturing companies, regardless of
size, type of product or manufacturing process is the need
to control the flow of material from suppliers, through
manufacturing and distribution to the customer.
Traditionally, the flow of material has been considered only
at an operational level, at best driven by efficiency
improvement and cost reduction, at worst abandoned to
be battered by the demands of a rapidly changing
competitive environment.
For many companies the need to react to market changes
is paramount; the role of the supply chain is crucial. No
longer can the potential of integrating the supply chain
be ignored. This potential will, however, only be realised
by recognising the connections and inter-relationships
between component parts of the supply chain and ensuring
a good fit between its design and operation and the
company's competitive strategy. Those companies that
consider the supply chain during the strategic debate,
manage it as a single entity and ensure the appropriate
use of tools and techniques in order to meet the needs
of the market, will obtain real benefits resulting from the
double-edged impact of increased market share on a lower
asset base. Those that do not will get left behind in the
fight for survival.

shipped direct to the line on-time; shared product, process
and specification change information; technology exchange
and design support, and above all, long-term commitment,
which usually means the elimination of multiple sourcing.
Summary
Common to all manufacturing companies, regardless of
size, type of product or manufacturing process is the need
to control the flow of material from suppliers, through
manufacturing and distribution to the customer.
Traditionally, the flow of material has been considered only
at an operational level, at best driven by efficiency
improvement and cost reduction, at worst abandoned to
be battered by the demands of a rapidly changing
competitive environment.
For many companies the need to react to market changes
is paramount; the role of the supply chain is crucial. No
longer can the potential of integrating the supply chain
be ignored. This potential will, however, only be realised
by recognising the connections and inter-relationships
between component parts of the supply chain and ensuring
a good fit between its design and operation and the
company's competitive strategy. Those companies that
consider the supply chain during the strategic debate,
manage it as a single entity and ensure the appropriate
use of tools and techniques in order to meet the needs
of the market, will obtain real benefits resulting from the
double-edged impact of increased market share on a lower
asset base. Those that do not will get left behind in the
fight for survival.
