ABSTRACT
The article examines the long term importance of cooperative relationship and the problems with single source suppliers. It is argued that the underlying principles of comakership agreement have to be carefully considered by the buying organization. Using case study, the authors are able to identify the problems and generalize measures which a buying firm can adopt when embarking upon long term/single source agreement with their suppliers.

COOPERATIVE RELATIONSHIP: THE NEXT
CHAPTER IN THE BUYER/SUPPLIER MANUAL
INTRODUCTION
The increased emphasis on quality and specification
coupled with purchasing's role as a communication channel
has placed greater demand on the buyer. As the trend
moves towards a single source and long term supplier,
buyers must reorientate their philosophy to make it
successful. During the past decade, as the concern for
quality and specification has reached an unprecedented
level, British manufacturers (especially the high
technology and safety industry) have faced the challenge
of declining product quality and the danger of loosing
business. In some instances, Government Control Bodies
have placed great demand on manufacturing companies to
implement quality control_techniques as a condition for
continued business. In turn, buyers have turned to their
suppliers and levied similar requirements on them.
This paper attempts to present some of the findings
from a case study of an American subsidiary located in
Scotland. The article details a case study of the long
term importance of a cooperative relationship, which is
often neglected by buyers, who, once they have gone for
single source, tend to "forget" about the constant need to
monitor and enhance their cooperative relationship with
911
their suppliers. This is especially so for firms with
high product quality demand and tight specifications.
Much has been written about single sourcing, long term
suppliers and the need for cooperative relationship where
benefits can accrue to the buying organization [1] [2] [3]
[4] [5] [6] [7], However, the "dangers and problems of
complacency" has not been explored. This paper seeks to
fill that gap by identifying the problems from the case
and providing solutions from the company's perspective.
The authors also attempt to generalize precautionary
measures to be taken by buyers who are intending to embark
upon long term/single source agreement with suppliers.
CONCEPT OF COOPERATIVE AND SINGLE SOURCE RELATIONSHIP
WITH COMPETITIVE STRATEGY
The priorities of the purchasing function, as with
any function, must be derived from the firm's competitive
strategy [8]. It is the role of the purchasing function
within a firm to structure and manage itself to support
and enhance the firm's ability to attain its desired
competitive advantage. The philosophy of the purchasing
system and its capabilities in terms of suppliers,
personnel and information should focus on the elements of
the competitive strategy that management considers
essential to the firm's success [9], For instance, if the
competitive advantage sought by a firm is high quality,
purchasing personnel may focus on simplifying material
912
specifications and developing the supplier's quality
performance. In essence, purchasing activities take on
the very nature of the competitive strategy [10].
Lenderos and Monczka [11] have stated that " a co
operative buyer/seller relationship" with few preferred
suppliers has enhanced purchasing function's ability to
support several strategic postures for a manufacturing
firm. They have illustrated the competitive advantage
that can be achieved by purchasing if it can combine its
skill and resources together with cooperative relationship
to support the three strategic postures of overall cost
leadership, product differentiation and market segment
focusing.
Cooperative buyer/seller relationships allow
purchasing managers to better manage the interdependent
tasks of the buying and selling firms, and to become
conduit of information between the manufacturing firm and
its preferred suppliers. Any purchasing department is
only as good as the sources that it buys from. Its
performance is heavily dependent upon the "partners" that
it chooses to do business with. Optimum performance of
both a purchasing department and its associated vendor
pool require a good working relationship between them
[12].
There is great emphasize on single sourcing and long
term supplier relationships as a long term purchasing
policy due to the significant implication for quality,
913
cost, dependability and flexibility given by these
suppliers [13] [14] [15].
Burt [16] has admonished that purchasing managers who
advocate the award of two or more contracts for the supply
of critical materials are "anachronistic in their
thinking". The concept of Just-In-Time (JIT) and
Materials Requirement Planning (MRP) advocate the use of
long term supplier with cooperative relationship. There
is a body of literature available which highlights the
many benefits that accrue to a buying organization as a
result of single sourcing [17] [18] [19] [20].
ATTRIBUTES OF COOPERATIVE RELATIONSHIP
There are five attributes in the cooperatitive
buyer/seller relationship which affects the competitive
performance of the buying firm [21]. These are:-
1. A supply pool consisting of one or a few preferred
suppliers
2. An alliance incorporating credible commitment
between the buying and selling firms
3. Joint problem solving activities
4. An exchange of information between the firms
5. Joint adjustments to market conditions
The major benefits of cooperative relationship can be
summarized as follows:-
* Purchasing professionals using a preferred supply
pool can maximise their bargaining power by concentrating
91U
their purchasing requirements and achieving economy of
scale that result in price discounts due to volume
purchases [22]. In addition, administrative costs are
reduced for both the buying and selling firms since
purchase orders, receiving reports, inspection reports,
payment and sales calls are reduced. Quality variability
is reduced, and often quality can be improved by focusing
problem solving efforts more sharply on one or a few
suppliers [23].
* There is a credible commitment between the buying
and selling firms, as there is a concentrated effort to
jointly improve quality and productivity and to reduce
overall cost. A buying firm's credible commitment is
extended to a selling firm (and vice versa) quite often
when both firms are facing uncertainities in their
operating environments and are highly interdependent [24].
* Firms participating in a cooperative buyer/seller
relationship attempt to work jointly to resolve the
disputes when they experience performance problems. It is
in the best long term interest of both firms to do so.
* In a cooperative buyer/seller relationship,
information must be exchanged to develop a credible
commitment between the buying and selling firms. The
exchange of information between the buying and selling
firms allows the firms to stabilize and co-ordinate their
interdependence [25] [26]. A cooperative buyer/seller
relationship, also provides a channel through which a
915
supplier may obtain useful information about such things
as product design and demand schedules. The enlightened
buyers willingly provide such information to help promote
mutual productivity improvements or lower total costs.
Additionally, the seller can provide the buying firm with
interrelated costs, quality and design data that can be
used to make intelligent trade off decisions that benefit
both firms [27] [28].
* Joint problem solving efforts can be used by the
buying and selling firms to develop mutual response to
changes in the market place.
Many manufacturing firms have found that major
economies and operating improvements can be made by
developing cooperative relationships with selected
suppliers [29] [30]. On the other hand, Newman [31]
identified eight major concerns as a supplier enters into
a long term working relationship with their customers.
These are:-
1. Shrinking customer base
2. All or nothing contract awards
3. Capacity obligations and profit margins
4. Supplier cost data
5. Misdirected cost reduction efforts
6. Cost of innovations
7. Interorganizational problems
8. Supplier identity
These concerns can give rise to problems in the long
916
term, if the suppliers are not exceptionally creative.
Thus, single sourcing with mediocre suppliers will produce
mediocre results. Single sourcing should follow once
suppliers, through their actual performance, have proven
they can be reliable and high quality producers.
Unfortunately, it is much easier to change from multiple
sources to a single source than to create outstanding
suppliers. Hence, "instead of climbing on the bandwagon
of single sourcing, the buying organization need to put
forth efforts to create outstanding sources. If not the
sources will produce nothing but disappointment" [32].
Though the brief review of the above literature
favours single sourcing/long term suppliers with co
operative relationship, the last statements by Leenders
and Blenkhorn signify an important point for organizations
to consider. It is also the belief of the authors that
due considerations need to be given by firms embarking
upon long term relationship with sellers. The following
case study attempts to highlight the pitfalls in a long
term relationship and the necessity for firms to be
cautious and to take necessary precautions. Instead of
gaining its competitive strategic posture, the firm almost
lost the competitive advantage of its long term supplier
relationship.
917
THE CASE STUDY: ABC CORPORATION
ABC is an American subsidiary based in Scotland. It
has been in existence for 25 years. Its function in
Scotland is to serve the European market. Other plants in
England and West Germany are co-ordinated to support
Europe's demand.
ABC's competitive advantage lies in its technical
expertise and design patents. They manufacture safety
products for the petrochemical, biomedical and mining
industries. As the products are used by people for their
safety, there is great emphasis on the products' quality
and specification needs. In Britain, the Health and
Safety Certificate (HSC) issued by the British Standard
Institute (BSI) is a prerequisite for ABC to manufacture
in United Kingdom.
The recent "Piper Alpha" disaster in the North Sea,
had a significant impact on the industry. This gave rise
to tightening of specifications and greater demand on
quality of finished product. The BSI tends to be very
stringent in their approval of licenses for the manufacture
of safety products.
ABC in its early days of production had identified
and selected suppliers for their critical materials. To
this date, these critical part suppliers are single source

918
suppliers who have been supplying for almost 20 years.
The following section will identify two major problems
encountered by the ABC corporation with their long term
suppliers.
PROBLEMS ENCOUNTERED
PROBLEM # 1
PRODUCT: EXPLOSION PROOF DETECTOR HEADS
The explosion proof detector head is a specially
designed helmet which detects gases which are explosive in
nature. The most important component inside the detector
head is the "explosion proof centre". The "centre" allows
the gas to filter through and then determines its volume.
When the gas entering the centre is more than a certain
value an alarm is set off and alerts the user. The
"centre" which allows the gas to come through is called
the "critical flame path".
The supplier who has been supplying for 20 years
changed the raw material to make the "centre" in the
detector heads. This resulted in the "critical flame
path" deviating from specification. No information was
given to buyer organization as the suppliers were
confident that they knew "what's best for their
purchasers".
By pure coincidence, when BSI/HSC inspectors checked
the centre of the detector heads, which will be used in a
new model for a new contract, they found the centre was
919
not according to specification. This resulted in a complete
halt of production for all the models of the explosion
proof detector heads. Quality assurance people started
checking product dimensions aganist drawing
specifications. The whole incident gave rise to near loss
of license to manufacture the product. Unless ABC takes
immediate measures to show their improved operation, they
are liable to loose their license to manufacture.
PROBLEM # 2
PRODUCT: SELF RESCUER UNIT FOR MINERS
The self rescuer unit is a high temperature
respirator for miners. It allows miners to breathe high
temperature air in an emergency. Every miner has to be
trained in the use of this apparatus. During training
high temperature air is produced by a mixture of chemicals
when a handle is released. The temperature is specified
in the range 69 to 71 degrees Celsius. Due to chemical
mixture variance, the temperature can be 1-2 degrees
Celsius lower. Thus the temperature was not according to
specification1. The batch was rejected by the quality
assurance personnel. As a result of problem f 1 the
quality assurance engineers were not taking any chances in
their acceptance criteria. The entire batch had to be
"scrapped". The irony of the situation was the chemicals
in the mixture are classified "dangerous" by the Ministry
of Environment and have to be disposed of correctly. The
buying organization had to pay the disposal costs of the
10
920
rejected batch.
When ABC highlighted problems # 1 and # 2 to their
suppliers, the suppliers' comment were......
"We have been making it like that for 20 years and it
has always been right.......J "
"It always worked and it has always been like
that.... 1 "
KEY OBSERVATIONS
As a result of this study, the authors observed the
following characteristics which gave rise to these
problems. These are:-
1. Purchasers are not "bothered" how the component
is manufactured. Nor did they care what type of material
was used in the process, as long the supplier meets the
specifications in the drawing. This is one of the fallible
attitude of buyers. With long term suppliers, buyers are
content and complacent, with the knowledge that, as
suppliers have been delivering for so long that they know
what they are supplying. As the supplier management gain
stronger bargaining power as being the single source, they
have taken the buyers for granted. This has also been a
direct result of buyer's complacent attitude to suppliers.
The suppliers' negative attitude, have resulted in
shipping "anything" which they think can be accepted. The
vendors belief is " send something, and when eventually
they (buyers) need it, they will deviate (increase
11
921
tolerance) it for acceptance !". The outlook by single
source/long term suppliers is that the buyers are at
"their mercy". The top management of the buying
organization put all the responsibility and blame of any
quality problems on the quality engineers. This "point
finger" attitude has caused the quality assurance
engineers to overreact "keep to the drawing".
2. The most important benefit for the long term
supplier relationship is two way communications. There is
a lack of integration and communication between the buying
organization and the supplier. The purchasing, design,
quality and production engineers are not willing to
discuss issues on specifications, designs and quality
performance of product. The comment from the ABC pur
chaser, "... my two senior purchasing guys and even myself
have difficulty in understanding the nature of
specification..." exemplifies the need for buyers to be
both technically orientated with commercial flair. Such
a background will "bridge the gap" between the engineering
staff and it will facilitate better interaction between
and discussions with, supplier engineers. There needs to
be discussions and exchange of information if problems are
to be solved jointly. A mutual understanding must be
established through communication for a cooperative
relationship to be constructive in its problem solving.
3. Being single source and long term suppliers with
no direct competitors, the suppliers have allowed quality
12
922
to "slip" by, in an attempt to cut costs.
4. The buying organization has no manual or
procedure which dictates that single suppliers are to be
appraised on a regular basis. In addition, there is no
monitoring and development system by ABC for its long term
suppliers.
With the occurence of these problems, ABC realized
the strategic impact on its operation. ABC were about to
loose their manufacturing license and in turn close their
operation in Scotland.
GENERALIZED MEASURES
From the case, the authors are able to identify and
generalize the following measures which a buying firm can
adopt when they are intending to embark upon long
term/single source agreement with suppliers. Typically,
there is no single option that will close all windows of
vulnerability for the buyer. The usefulness and
applicability of these measures depends on the individual
buying situation.
1. Establish the correct attitudes and ensure
trust through contractual obligation
2. Establish communication and computerization
3. Initiate program and procedure for supplier per
formance evaluation and development
4. Monitor performance evaluation and launch supplier
development activities
13
923
5. Implementation and further evaluation of the
supplier development program
ATTITUDE AND TRUST
When a firm adopts single source strategy/long term
supplier, it is essential that the buyer-supplier
relationship be one of genuine cooperation, including the
sharing of pertinent cost information. Buyers must
understand vendors' motivations and concerns about single
source relationships if they expect to deal effectively
with selected vendors in developing such relationships.
Most single source relationships are initiated by buyers,
however, once a vendor has positioned itself to be a
suitable single source, it should capitalize on its
distinctive advantage, eg. improved product quality.
This mutual understanding and trust is the basis for
cooperative and constructive problem solving. As noted in
the case, with no direct competitors, the vendors may
allow quality to "slip" in an attempt to cut costs. How
ever, if a vendor truly understands the benefits of
greater quality, they will realize that such action is
counter productive. Nevertheless it does happen and it
can have an adverse impact on the buyer as well as the
seller. Although single source/long term relationships
should involve considerably mutual trust, the buyer
probably needs to write some type of "unacceptable quality
escape clause" in the long term contract. If objectively
14
written, such clause benefits both parties because
conditions and management change over time.
COMMUNICATIONS AND COMPUTERIZATION
The developments in computerization and communication
technology have had a major impact on the management and
execution of the procurement function. Their effective
combination offers massive opportunities for major changes
in the field of purchasing and the accomplishment of
different objectives. An improved two-way communication
can be established if the performance of the supplier is
computerized. An objective monthly/weekly performance
report can increase the rapport between buyers and
suppliers. The suppliers will be on their "toes" as they
are constantly made aware of their performance.
Furthermore, communication can be enhanced if the
purchasers have a technical background especially in the
case of technically orientated firms. Such a background
enables the buyer to communicate with engineers as he can
speak the same "lingo". This also enhances the inter
action with suppliers, as they don't have to wait to meet
engineers but discuss technical issues with the buyers. A
computerized supplier data bank with continuous updating
of capacity and capabilities will add a dimension of
alertness to the buyers and instil that alertness in the
suppliers. Another form of communication is for the firm
to provide a "vendor clinic" or "vendor workshop" for
15
925
suppliers. This will enable them to share their concerns
and plans and to ask for their suggestions and co
operation. This needs to be done on a regular basis. Such
continuous interaction and mutual assistance from these
meetings will result in a concerted effort to build a
relationship, hence producing a team spirit of "joint
pursuit of compatible goals".
INITIATE PROGRAM AND PROCEDURE
The need to initiate a program and procedure for
supplier performane evaluation and development must first
be recognized by top management. Generally, the need for
a program is recognized through management's desire to
improve the firm's competitive position or to meet specific
competitive challenges in the market place. It can be
initiated by purchasing or by other concerned functional
areas within the buying firm. The program is then
formalized into procedures to initiate follow-up
discussions with suppliers. The recognition of these
needs is then translated into a set of objectives dealing
with various performance measures such as quality
improvement, cost reduction, or more reliable delivery
performance. This should be followed by the formation of
a management team, department or committee. The team
can be organized by categorization of critical suppliers
or materials.
16
926
MONITOR PERFORMANCE EVALUATION AND LAUNCH SUPPLIER
DEVELOPMENT ACTIVITIES
For long term/single source suppliers , there need to
be continuous performance evaluation. When the buying
firm is not satisfied with current performance levels of
the existing suppliers or recognize the need for further
improvement, it may have to initiate supplier development
activities with the supplier. If the firm has new or
modified requirement that cannot be adequately satisfied
by existing suppliers, it may proceed to evaluate new
vendors. Such an evaluation facilitates the final
selection of new suppliers and can further identify the
developmental areas that must be worked on with each
existing supplier.
Suppliers can be evaluated on the basis of their
technical, quality, delivery, cost, managerial and
attitude capabilities. Evaluation results subsequently
have to be compared aganist the buying firm's requirements
or future objectives. When each supplier's performance is
evaluated regularly, the degree of developmental
assistance required can be determined on the basis of this
evaluation. Hence, supplier evaluation is an integral
part of supplier development and the evaluation result can
serve as a basis to launch an ongoing improvement program.
The basic purpose of supplier evaluation is to
continuously improve the supplier's performance.
17
927
Once supplier evaluation is completed, the next step
is to identify the areas for improvement. Supplier
evaluation results provide valuable information about
general areas of weakness, but the results are usually
too general to be useful. For example, the supplier
evaluation process may show that the supplier is weak in
its ability to maintain quality. However, the buyer still
does not know the exact cause of the quality problem. It
could be related to design, to the manufacturing process
or simply to poor workmanship. Chan K. H et.al [33]
provide a supplier development activities matrix where
they classify supplier performance problems into 2
categories. Firstly, the supplier capabilities
technical, manufacturing, quality, delivery, financial and
managerial. Secondly, in terms of their sources - e.g
product, process or operating systems. The matrix
assists in defining the problem more precisely (see also
[34] [35] [36] [37]). At this point, the supplier's
management must be invited to participate in the analysis.
It is important that early supplier involvement in the
analysis be encouraged as it is critical for successful
program implementation.
IMPLEMENTATION AND FURTHER EVALUATION
The development program must be implemented and when
the implementation is completed, the results again have to
be evaluated on the basis of developmental as well as the
18
928
specific technical, quality, delivery and cost capability
objectives. As market conditions demand continuing
improvements in products and services, the program has to
be the continuous monitoring and upgrading of the
supplier's capabilities to meet the long term objectives
of the buying firm.
CONCLUSION
Current market conditions necessitate a longer
planning time horizon than was traditionally employed in
the field of procurement. Improved quality, delivery,
cost, flexibility, positions in learning curve,
computerization and communication systems all require
purchasing to achieve better results and this in turn
requires time.
Time is an element which has both positive and
negative aspects related to long term planning. This is
especially so in respect of single sourcing and long term
relationship. In today's competitive market environment,
however, there is a critical need to monitor, appraise,
evaluate and provide continuous development programme for
suppliers. The authors [38] do not dispute that single
source/long term suppliers with cooperative relationship
can contribute positively to the strategic advantage of
the firm, but the experience from the case highlights that
the buying organization must always anticipate long term
problems and take necessary precautionary measures to
avoid them.
