Abstract
Inventory control is a well-covered area in literature. Nowadays, many concepts and techniques are available for
effectively controlling inventories. Eminent examples are stochastic models to determine order quantities, techniques
for forecasting demand and different kinds of ABC analysis. Remarkably enough, the theoretical backgrounds of
these concepts and techniques show a great deal of similarity: they all stem from the field of operations management
and operations research. Despite the value of the available concepts, such a one-sided approach has its limitations in
practice. In this article it is argued that it is important to take a broader view when dealing with practical inventory
control problems. First of all, an organizational perspective on inventory control is developed. The main idea behind
this perspective is the importance of the organizational context of inventories. This means that in addition to the
traditional points for attention, such as order quantities and replenishment strategies, other aspects need attention as
well. They are, for example, the allocation of responsibilities and authorities regarding inventory management, the
quality of inventory information and the relevant decision-making processes. These contextual factors as well as the
traditional factors are mapped out and integrated into a framework to be used in solving practical inventory control
problems. One of the main features of the framework is that it is useful in both analyzing and redesigning an inventory
situation. Secondly, this article describes the results of a case study regarding the application of the organizational
perspective to a practical inventory control problem. The central issue of the case study is the spare parts inventory of
a missionary aviation organization in Africa. The case study shows that the organizational perspective on inventory
control is very helpful in dealing with inventory control problems. It is illustrated that taking into account the
organizational context of inventories, especially the responsibilities and authorities of the persons concerned, is a
necessity to accurately understand inventory control problems. In addition, it is illustrated that the organizational
perspective leads to a more appropriate redesign.

1. Introduction
During the last few decades inventory control has been the topic of many publications. It may fairly be called one of
the classics in operations literature. As a result, a large collection of concepts and techniques is available for
effectively controlling inventories. There are for example stochastic models to determine order quantities, techniques
for forecasting demand and different kinds of ABC analysis. Recently management systems such as manufacturing
resource planning (MRP) and enterprise resource planning (ERP) have been added. However, most of these
contributions have similar theoretical background: the field of operations management and operations research. This
means the concepts and techniques are mainly based on mathematical assumptions and modeling inventory
situations. Although this established approach to inventory control has proved to be very valuable in determining
inventory parameters and planning resources, its value can be questioned in dealing with practical inventory control
problems. Plossl and Welch for instance state that many firms have inventory control techniques working but they are
not reducing inventories. On the other hand, some others are doing a fine job of managing the total inventory
investment even without these tools (Plossl and Welch, 1979, p. 26). In addition, nowadays’ authors realize that many
of the quantitative methods from the field of operations management and operations research are insufficient to cope
with today's organizational complexity (e.g. Hayes, 1998; Lovejoy, 1998; Machuca, 1998). These authors favor a
broader scope on operations management issues, including qualitative aspects and linkages with other functional
areas in an organization. Therefore, there seems to be a need for an extended view on inventory control.
In this article we argue that it is highly important to take the organizational context of inventories into account when
dealing with inventory control problems. This means that in addition to the traditional points for attention, such as
order quantities and replenishment strategies, contextual aspects need attention as well. They are for example the
allocation of responsibilities and authorities regarding inventory management, the quality of inventory information and
the relevant decision-making processes. These contextual factors as well as the traditional factors can be integrated
into an organizational perspective on inventory control. The development and practical application of this
organizational perspective are the main topics of this article.
The article is organized as follows. First, the organizational perspective on inventory control is developed. To that
end, the organizational context of inventories is investigated to determine aspects that play a part in inventory control.
Second, a framework is presented to facilitate the application of the organizational perspective to practical inventory
control problems. The third section of this article describes the research methodology of a performed case study in
which the organizational perspective has been applied. The case study regards the spare parts inventory of a
missionary aviation organization in Africa. Fourth, the results following from the case study are presented. It can be
concluded that taking the organizational context of inventories into account leads to a better understanding of the
problem and to a more appropriate redesign of the inventory situation. The final section of this article summarizes the
conclusions.
2. An organizational perspective on inventory control
Within the area of operations management and operations research many contributions regarding inventory control
can be found. Traditionally they focus on three topics that are widely recognized to play an important part in inventory
control: order quantities, order intervals and inventory control systems. See, for example, Plossl (1985) and Silver et
al. (1998). The first topic regards order quantities or how much to order. In order to determine economic order
quantities, several costs associated with inventories play a part, such as ordering costs and inventory carrying costs.
The second topic regards the order interval or when to order. In this respect demand and lead-time processes are
important. Finally, the third topic regards the inventory control system. Common subjects concerning systems for
controlling inventories are ABC classifications and information systems. These three aspects represent the traditional
characteristics of an inventory situation. In addition, they are considered to be starting points for improving inventory
control. Over the past two decades, as the field of operations management has developed and matured, several new
concepts have been added to the list of relevant inventory control topics. These more management-oriented topics
include MRP, just-in-time (JIT) and ERP (Hayes, 1998; Leschke, 1998). Although these recent contributions have a
more qualitative nature, they show the same one-sided scope on inventory control as the previous contributions. In
fact, most contributions pay little or no attention to the fact that the majority of inventories are situated in an
organizational context.
From a practical point of view it seems that the organizational setting of inventories should not be disregarded. Being
situated within an organizational context several other factors play a part in inventory control. In general these factors
lie outside the field of operations management and operations research but should nevertheless be taken into
consideration. Most factors regard the organizational incorporation of inventories and the associated information
flows. A significant example concerning inventory management is the allocation of responsibilities and authorities.
Inventory control problems can easily arise when for instance nobody in the organization is responsible for the
inventory or the responsible person has insufficient authorities to carry out the task. Likewise, high inventory values
indicating a lack of control may just be the result of inaccurate inventory records or of a reporting system that does
not function well. Thus, the organizational context of inventories also contains several aspects that can affect
inventory control.
In order to identify significant aspects in the organizational context of inventories four dimensions can be
distinguished. They are the allocation of tasks, decision-making processes, communication processes and behavior
of the parties involved, as displayed in Fig. 1. First, the allocation of tasks is an important dimension in the
organizational context of inventories. According to Lovejoy (1998) this dimension should be part of the foundations of
an integrated view on operations management issues. Relevant characteristics in this respect are the number of
people that are responsible for inventory management, their functional positions and their hierarchical positions in the
organization. Another relevant characteristic is the fit between allocated responsibilities and authorities. Each one of
these characteristics might influence the effectiveness of inventory control.

Second, organizational theory shows that decision-making processes form a significant organizational dimension
(e.g. Daft, 1998). Like in other organizational areas, many decisions are made in inventory management, varying
from annual strategic decisions to operational decisions concerning day-to-day activities. The resulting inventory
control is influenced by how these decisions are made. Furthermore, the effectiveness of inventory control depends
on the ways in which inventory decisions relate to each other and to other decisions in the organization. It is evident
that, for instance, contradicting decisions or decisions that are based on wrong information can influence the
effectiveness of inventory control.
Third, communication processes represent another dimension in the organizational context of inventories. As
stressed by organizational behaviorists, communication is a key process underlying all aspects of organizational
operations (e.g. Greenberg and Baron, 1993; Robbins, 1993). In this respect it is important to consider the influence
of communication processes on inventory control. For example, the forwarding of inventory information, the quality of
that information and the provision of feedback can have a large impact on the effectiveness of inventory control.
The fourth and final dimension of the organizational context that is important with respect to inventory control is the
behavior of the parties involved. Since the Hawthorne experiments in the thirties it is widely recognized that social
aspects influence the functioning of organizations (Dessler, 1986; Paul et al., 1994). Lovejoy (1998) points out that
human behavior should not be ignored in operations management issues. In fact, social aspects can be significant
determinants of the effectiveness of inventory control. For example, conflicts might prevent people from passing on
important inventory information. In addition, power can obstruct decision-making processes concerning inventory.
Likewise, motivational problems, uncertainty or incompetence influence the ways in which inventory tasks are
executed. Therefore, it is important to consider not only the formal aspects of the allocation of tasks, decision-making
processes and communication processes, but also the informal aspects in terms of behavior and underlying factors.
Hence, in the organizational context of inventories four dimensions that play a significant part in inventory control can be identified. These dimensions should be taken into consideration when dealing with practical inventory control problems, additional to the traditional points for attention following from the field of operations management and operations research. The resulting approach can be called an organizational perspective on inventory control. This approach has two important characteristics. In the first place, the concept of inventory control is looked at from a multiform point of view. This means attention is no longer focused on just order quantities, order intervals and inventory control systems. Instead, other aspects of inventory control, belonging to the fields of organizational theory and organizational behavior, are highlighted as well. In the second place, the concept of inventory control is looked at from an integrated point of view. This means not only several different sides of inventory control are discussed, but also a great deal of attention is paid to the coherence between the different dimensions. This is an important aspect, since it is the coherence that ultimately determines the effectiveness of inventory control in a practical situation. For example, suitable replenishment strategies can be counteracted by inappropriate allocation of responsibilities. In the same way undesirable behavior may disturb sound decision-making and communication processes. A lack of coherence can easily arise as a result of conflicting interests. It is generally accepted that organizational members involved in for instance sales, production or finance value inventories differently (Plossl, 1985; Silver et al., 1998). Depending on their involvement in determining aspects of inventory control, there will be little or much coherence. .Thus, it is desirable to pay attention to the interaction between the several dimensions of inventory control rather than to traditional aspects or communication processes separately. The next section of this article presents a framework that can be used to apply the organizational perspective to practical inventory control problems.
3. An integrated framework
The employment of the organizational perspective on inventory control in practice can be facilitated by means of the
framework presented in Fig. 2. The framework displays a way of approaching practical inventory control problems. It
is based on a basic control loop to represent the underlying problem-solving process. In general, the starting point for
a problem-solving process is an inventory system that performs below pre-set standards. In many cases, these pre-
set standards are defined in terms of costs. Some examples of costs associated with the ‘performance’ of inventory
systems are storing costs, stock-out costs, ordering costs and costs due to obsolescence. The performance of an
inventory system refers, however, not only to well-defined cost criteria. Actually, the main purpose of inventory
management is to facilitate the smoothing between supply and demand. So any symptom indicating a lack of
harmony between supply and demand may refer to a poor performance of the inventory system. Examples of some
of these symptoms are instabilities in the (production) planning process, the existence of numerous rush orders and
inefficient operation of production facilities. In many cases a deviating performance of the inventory system will
activate a diagnosis of the inventory situation in which several aspects regarding inventory control are investigated
(cf. Fig. 2). The outcome of this diagnosis then serves as input for the construction of a redesign of the inventory
system.

Within this framework, there are a few guidelines for the diagnosis and redesign phase following from the application
of the organizational perspective on inventory control. To begin with, applying the organizational perspective on
inventory control in a problem-solving process partly determines the structuring of the diagnosis phase of the
process. The objective of this phase is to achieve a clear insight in the inventory situation under consideration and a
thorough understanding of the cause(s) of the inventory control problem. To that end, the inventory system needs to
be described and analyzed. With regard to describing an inventory system it is important to obtain a comprehensive
description of the inventory system. The end result should contain detailed descriptions of both traditional aspects of
inventory control and aspects from the organizational context of the inventory system. This is to ensure a large
amount of factors that might play a part in the inventory control problem are included in the description. Therefore, the
first guideline of applying the organizational perspective on inventory control in practice regards describing an in
3666ventory system by paying attention to each of the five dimensions that have been identified to play a part in
inventory control. The table in Fig. 3 can be a useful tool to do so. The table presents an elaboration of traditional
aspects, the allocation of tasks, decision-making processes, communication processes and behavior regarding
inventory control. Each dimension is divided into relevant aspects and their characteristics. Although the list of
characteristics is by no means meant to be exhaustive, it is composed in such a way that it will lead to a fairly
complete insight in an inventory situation.

The second guideline of applying the organizational perspective on inventory control in practice regards analyzing an
inventory system. When trying to determine causes for an inventory control problem, all five dimensions should be
taken into account. It is important to begin with analyzing each of the five dimensions separately and subsequently
focus on analyzing the coherence between the dimensions. This implies that firstly for each of the dimensions it is
investigated in what ways it contributes to the inventory control problem. The table in Fig. 3 can provide starting
points for identifying possible causes. This part of the analysis might reveal for instance that an inappropriate
replenishment strategy is applied or that communication systems are not functioning properly. Secondly, the findings
from every dimension are integrated to determine how the dimensions relate to each other. For example,
malfunctioning communication systems might cause the inappropriate replenishment strategy. In addition, the
malfunctioning communication systems might be the result of an inappropriate allocation of tasks. Doing so, it will
become clear what causes the inventory control problem from an organizational perspective.
Besideks guidelines for the diagnosis of an inventory control problem, the organizational perspective on inventory
control also provides guidelines for the redesign of an inventory system. Based on an accurate understanding of the
inventory control problem, the redesign aims to improve the situation or solve the problem by means of
recommendations. From the organizational point of view it is important to take all five dimensions of inventory control
into consideration. However, unlike in the description and analysis of an inventory system, the five dimensions are not
expected to be equally important. Depending on the outcomes of the diagnosis of an inventory system, it might be
sufficient to redesign just one of the dimensions. In other cases, a redesign of the entire system might be required.
Still, in all cases it remains necessary to consider each of the five dimensions, since they are closely interrelated. For
example, changing the allocation of tasks can influence communication processes. Likewise, improving decision-
making processes can solve behavioral problems. Therefore, the third guideline of applying the organizational
perspective in practice regards redesigning an inventory system by taking the five dimensions of inventory control into
account, although it is not needed to change them all.
To conclude, the framework presented in Fig. 2 facilitates the practical employment of the organizational perspective
on inventory control. The accompanying guidelines provide support in diagnosing and redesigning an inventory
system. This way of applying the organizational perspective to practical inventory control problems is expected to
lead to more satisfying solutions. In the first place this is due to the comprehensive description and analysis of an
inventory system. Compared to the traditional approach to inventory control, the organizational approach is more
likely to capture the complex environment most inventories are situated in. This is expected to lead to a more
accurate understanding of the inventory control problem. In the second place, more satisfying solutions are to be
expected because of more appropriate redesigns. Traditionally, redesigns were focused on changes in order
quantities, order intervals or inventory control systems. However, it has been argued that in several practical
situations the organizational context of inventories needs to be changed in order to improve inventory control.
Therefore, the organizational perspective paying attention to both traditional and contextual aspects will lead to more
appropriate redesigns. The next sections of this article describe the research design and results of a case study in
which the organizational perspective has been applied to a practical inventory control problem.
4. Research methodology
The organizational perspective on inventory control as introduced in the former sections has been applied in a
practical situation. This case study regards the spare parts inventory of Mission Aviation Fellowship (MAF) Europe.
MAF Europe is an international missionary aviation organization that is part of a worldwide group of MAF
organizations. The purpose of the organization is to multiply the effectiveness of the mission of the body of Christ in
areas of need through aviation, information technology and logistical services. Through these services MAF Europe is
attempting to enable national churches, international missions and non-governmental organizations to provide
spiritual and social benefits to people in developing countries. Today, MAF Europe programs are located in Chad,
Kenya, Madagascar, Tanzania and Uganda, while a new program is being set up in Mongolia. The headquarters of
the organization is located in the United Kingdom. In order to provide its services, MAF Europe operates an aircraft
fleet consisting of almost 30 aircrafts in eight different types, mostly from the Cessna factory. In general, engineers in
the programs maintain the aircraft. To that end, every program carries a spare parts inventory that is controlled at the
spot. In order to limit the amount of money that is tied up in spare parts, the Board of Directors of MAF Europe has
declared that the aggregate value of aircraft spare parts is not allowed to exceed 7.5 percent of the insurance value
of the aircraft fleet. However, the MAF Europe programs have been outside this constraint for some time. In January
1999, the inventory of spare parts had a value of $850,000 while the aircraft fleet was insured for $10,000,000. That
results in a ratio of 8.5 percent. Therefore, the organization was in need of a research study leading to
recommendations to improve the situation.
The research study has been carried out during a period of 6 months in which the researcher was part of the
organization and located in Africa. Data were collected by interviewing people, studying documents and analyzing
numerical data. Since there were indications that factors from the organizational context were contributing to the
inventory control problem of MAF Europe, the organizational perspective was adopted to approach the problem. The
research performed can be characterized by the framework presented in the former section. First, the current
inventory situation in the MAF Europe programs was described multiformly by means of the five dimensions identified
to play a part in inventory control problems. Second, the current inventory situation was analyzed in order to
determine factors contributing to the inventory control problem. Both traditional and contextual aspects were analyzed
by using theoretical concepts from the fields of operations management and operations research or more
organizational literature, such as theories on motivation and information. Third, following from the main causes of the
inventory problem in the MAF Europe programs, recommendations for improvements were presented. The
recommendations mainly regarded improvements affecting the organizational context of the spare parts inventories.
Together the recommendations were aimed at more effective inventory control. The next section of this article
describes some of the findings of the case study.
5. Findings of the case study
The main finding of the case study is the clear value of the organizational perspective in solving practical inventory
control problems. Through the application of the organizational perspective to the inventory control problem of MAF
Europe, significant causing factors were brought to light that probably would not have been recognized when the
problem was approached from a more traditional point of view. Likewise, the resulting recommendations regarded
essential changes in the organizational context of the spare parts inventories that most likely would not have been
part of a traditional redesign. This is explained in more detail below.
In the case of MAF Europe, the inventory control problem was reflected in the high value of the spare parts
inventories, which caused the programs to be outside the inventory constraint imposed by the Board of Directors.
Describing and analyzing the inventory control problem from the traditional perspective revealed that the MAF Europe
programs were applying a suitable control policy for ordering spare parts. Despite some minor issues, there were no
factors that contributed significantly to the inventory control problem. Therefore, from this operations management
point of view the spare parts inventory situation seemed to be in order. Recommendations that could be made
regarded fine-tuning order quantities and implementing the ABC classification. However, these recommendations
were not expected to solve the inventory control problem of MAF Europe. In fact, the main cause for the inventory
control problem was to be found in the organizational context of the spare parts inventories.
Each of the four contextual dimensions contributed to the inventory control problem. In the first place, the allocation of
tasks in the MAF Europe programs hampered effective inventory control. In the organization of MAF Europe Chief
Engineers are responsible for the spare parts inventories. However, the main task of a Chief Engineer is to ensure
maximum availability of aircraft for operational use. Since it supports the maintenance of aircraft, the engineers will
naturally pursue a large spare parts inventory. Second, decision-making processes in the MAF Europe programs
influenced inventory control. This particularly regarded goal setting. For example, the decision to limit the aggregate
value of the spare parts inventories to 7.5 percent of the insurance value of the aircraft fleet was used as a goal.
However, for various reasons this goal was unsuitable so that it had little effect. The third dimension of the
organizational context, communication processes, also played a part in the inventory control problem of MAF Europe.
One communicational aspect that hindered effective inventory control was the low quality information that was used
to determine the value of the spare parts inventories. Fourth and finally, there were behavioral aspects that
contributed to the inventory control problem in the MAF Europe programs. Although power games, politics and
conflicts were not involved, a lack of clarity played a part. This made for instance that certain inventory procedures
were not followed.
Besides analyzing the five dimensions separately, the inventory system as a whole has been analyzed as well. This
revealed that the dimensions were closely interrelated. For example, the allocation of tasks in which engineers were
responsible for the spare parts inventories caused traditional inventory characteristics, such as order quantities and
replenishment strategies, to be aimed at large spare parts inventories. In addition, this was enabled by a lack of
supervision due to an inappropriate allocation of responsibilities in the hierarchical layers of the organization. In the
same way, this inappropriate allocation of tasks caused communicational problems such as a lack of feedback.
Furthermore, the decision-making processes in MAF Europe induced certain behavior damaging inventory control.
Finally, a combination of the allocation of tasks, communication processes and behavior of the parties involved
caused inventory information to be of low quality. To conclude, the organizational context of the spare parts
inventories in the MAF Europe programs consisted of a set of interrelated factors, i.e. regarding the allocation of
tasks, decision-making processes, communication processes and behavior, that contributed to the ineffectiveness of
the control of the inventories. Therefore, from the organizational perspective on inventory control the spare parts
inventory situation was not in order at all.
In accordance with the findings from the diagnosis the spare parts inventory situation in the MAF Europe programs
has been redesigned. Two major recommendations were made to the organization. They mainly regarded changes in
the organizational context of the spare parts inventories, as the main causes for the inventory control problem
stemmed from the organizational context. Since there were a number of factors contributing to the inventory control
problem, the recommendations were focused at aggregate solutions laying foundations for further improvements.
First of all, it was recommended that MAF Europe replaces the current inventory constraint by another goal that
would be more suitable. Having an appropriate goal to compare the programs’ performance to is an important
requirement for effective inventory control (Plossl and Welch, 1979). Although the inventory constraint in its current,
aggregate form can remain as a tool for top management, it has to be translated in inventory values for the individual
MAF Europe programs. It was recommended this should be done by defining end-of-year inventory values per
program, like a budget. This recommendation will have an effect on decision-making processes and subsequently
behavior of the parties involved in inventory management. Second, it was recommended that MAF Europe improves
its information flow by means of communicating inventory procedures and adopting a new reporting system for
inventory values. These changes will affect communication processes and behavior in the MAF Europe programs.
The proposed reporting system also affects the allocation of tasks. Doing so, the spare parts inventories in the MAF
Europe programs will most likely be controlled more effectively.
In conclusion, applying the organizational perspective to the inventory control problem of MAF Europe has given the
organization a comprehensive description and analysis of its spare parts inventory situation. In itself, this information
can already be of large value to the management of the organization. Furthermore, MAF Europe has received
recommendations that are not that evident from an operations management point of view, but nevertheless are
important. In fact, they are essential starting points in order to improve the control of the spare parts inventories.
Hence, from this case the conclusion can be drawn that the organizational perspective is indeed valuable in solving
practical inventory control problems.
6. Conclusion
From the above several conclusions can be drawn. First, this article has lead to a broader view on inventory control.
This broader view regards the organizational perspective on inventory control that has been developed. The main
idea behind this perspective is the importance of the organizational context of inventories for the effectiveness of
inventory control. It has been argued that the traditional approach to inventory control from the fields of operations
management and operations research pays little or no attention to the organizational setting of inventories. However,
the organizational context of inventories contains several factors that play a part in inventory control. They have been
identified as the allocation of inventory tasks, decision-making processes regarding inventory, communication
processes concerning inventory information and behavior of the parties involved in inventory management. In the
organizational perspective on inventory control these four dimensions are taken into account along with traditional
aspects of inventory control. It can be concluded that this organizational perspective on inventory control can be of
large value in practice. The case study regarding the spare parts inventories of MAF Europe has shown that factors
from the organizational context of an inventory can indeed play a significant part in inventory control problems. In
particular, the case study has emphasized the importance of coherence between the dimensions.
Second, in this article a way of approaching practical inventory control problems from the organizational perspective
on inventory control has been developed. This approach consists of a set of guidelines referring to a problem-solving
process. In the first place it has been argued that a diagnosis of an inventory system should contain a comprehensive
description. This means both traditional characteristics of an inventory system and the four dimensions in the
organizational context of an inventory should be described. Secondly, it has been argued that an inventory system
should be analyzed by paying attention to each of the dimensions separately and subsequently to the coherence
between the dimensions. Thirdly, when redesigning an inventory system each of the traditional and contextual
dimensions should be taken into consideration, although it might not be needed to change them all. This is due to the
interaction between the dimensions. It can be concluded that this proposed set of guidelines is a helpful tool in
solving practical inventory control problems. It aids in systematically applying the organizational perspective on
inventory control. The case of MAF Europe has shown that this way of applying the organizational perspective leads
to a more accurate understanding of an inventory control problem and a more appropriate redesign of an inventory
system.
Nevertheless, future research is required for the organizational perspective on inventory control to grow in size. This
article has initiated its development, but it mainly focused on the creation of an instrument that would be most useful
in practice. Therefore, further research needs to be conducted to consolidate the foundations of the perspective. In
this respect the relation between the organizational context of inventories and the effectiveness of inventory control
needs to be investigated in more detail. In particular, it is worthwhile to explore the specific contributions of the
dimensions that have been identified in this article research is likely to contribute to a refinement of the guidelines
proposed in this article, so that the practical employment of the organizational perspective on inventory control will be
further improved as well.
