Agribusiness Perspectives Papers 2001Paper 48 Supply Chain Management: Fad, Panacea or Opportunity?Anthony J. Dunne
IntroductionSupply chain management has certainly been one of the hottest topics in agribusiness management circles over the past five years. But, what is supply chain management? What are its benefits? What, if anything, is its relevance to agribusiness and in particular to farmers? The purpose of this paper is to bring together the disparate views on supply chain management so that agribusiness professionals and researchers will have a common framework within which the complex issues and problems confronting agribusiness firms can be analyzed, discussed and hopefully resolved. As with any management concept, supply chain management (SCM) means different things to different people. To most, SCM is all about logistical efficiency – the efficient transport handling and storage of physical products through the various stages of production and distribution to the final consumer. This is not a bad place to start because it is essential to the whole marketing concept that the right product gets to the right place, at the right time, in the right condition, in the most efficient manner.
But logistical efficiency is only one aspect of SCM when the term is used in a competitive strategy context. In this context, SCM combines the quest for logistical efficiency with the drive for creating customer value as a means of achieving sustainable competitive advantage for the firms involved.
In a strategic sense, the adoption of SCM requires managers of firms servicing a consumer market segment to re-evaluate their business relationships with input suppliers and buyers of their products. This re-evaluation usually involves a shift in their focus from an adversarial to a co-operative relationship. As a result, the competitive focus shifts from that between firms within one supply chain to that between different supply chains which service a common market segment. What is driving the acceptance of SCM? Australian agribusiness in the 1990's has experienced a prolonged period of adjustment and there is no reason to expect that this will change. Rather than resist change, which in the long term is fruitless, a more productive course of action is to investigate ways of adapting to these forces so as to take advantage of the opportunities that change opens up. Dunne (1999a) identifies three basic forces that drive change in the agribusiness sector:
Boehlje et al.(1995) claim that these changes have such a dramatic impact on the management of an agribusiness firm because they effect the competitive environment of the firm and influence the way in which the management of the firm will reorganize its internal resources to meet these challenges (Figure 1). In the case of agribusiness firms the changes in the competitive environment are usually reflected in changes in:
Since change in any business is difficult to achieve in the absence of a crisis that would leave a firm in a vulnerable strategic position, it is worthwhile examining the scope of these changes and the ramifications of their potential impact. Globalization[1]Over the past 50 years, there has been a drive to liberalize world trade through the reduction in tariff and non-tariff barriers that individual countries have imposed to protect their domestic industries. The principal instrument in the fight for trade liberalization has been the General Agreement on Tariffs and Trade (GATT).[2] Although there has been considerable success in liberalising trade in manufacturing goods, progress in the agribusiness sector has been limited because of the importance of food and fibre industries to the social fabric and national security of individual countries. Figure 1: The Forces of Change During the Uruguay Round of GATT (1987-94), agricultural trade issues were firmly on the agenda and the major blocs involved in the negotiations – the United States, the European Union, Japan and the Cairns Group, agreed to significant concessions which were formalised in The Agricultural Agreement (www.wto.org). The Millennium Round that was scheduled to commence in 2000, will be conducted in a much more difficult environment as individual countries assess the impact of market liberalisation on their domestic economies. For example, a new term - 'multifunctionality' has entered the lexicon of international trade. This term is used to defend the protection of domestic agricultural industries on social and environmental grounds. Trade liberalisation is a two-way street. In Australia's case the Agricultural Agreement is improving access to export markets for our products but it is also opening our domestic markets to import competition. A point painfully brought home to the Australian pork industry in 1997-98 (Dunne 1999b). TechnologyRapid advances in technology, in particularly in the fields of biotechnology and communication, are revolutionising the way food and fibre products are produced, processed, distributed and consumed. These advances have resulted in what Boehjie (1996) refers to as the ‘industrialization of agriculture'. But technological advances are not without their problems. For example:
Confronted with the challenges posed by changes in technology, firms will be required to demonstrate flexibility in integrating these new technologies into their business operations. PeopleThe impact of people on the agribusiness sector stems from their dual roles as consumers and guardians. Changes in the demographics, incomes and social awareness of people alter the nature of demand for food and fibre products while also influencing how these products will be produced and made available to the public. For example, in developed countries there is a well-established trend towards what is being termed ‘mass individualization'. Consumers are demanding an ever-increasing variety of products to match their growing disposable incomes and a lifestyle which is increasingly time poor. Associated with their increasing affluence, people have developed an increased awareness of health, welfare and environmental issues. This increased awareness has impacted on the agribusiness sector through increased regulation of how food and fibre products are produced. There are many examples of this:
There is no doubt that agribusiness firms are being influenced by rapid changes in their competitive environment. It is also clear that the pressure for change is persistent and has intensified over time. As a result, the challenge for agribusiness managers is to formulate strategies to accommodate these changes. The question is,, will the concept of supply chain management assist this process? Before this question is discussed there is value in examining the theoretical basis that underpins the concept of SCM. What are the theoretical foundations of SCM?In its broadest sense, supply chain management is concerned with the interactions between firms, ranging from raw material input suppliers to retailers that are serving a specific market segment. Irrespective of the focus of these interactions – improved efficiency or enhanced competitive position, SCM is multi-disciplinary approach and therefore has its foundations in a range of academic disciplines. The most important of these are economics, strategic management and marketing. Improved efficiencyTraditional microeconomic theory holds that the basic coordinating mechanism between firms in a supply chain is the market. But, as Coase (1937) points out, while market transactions are common outside the firm as a means of directing production, inside the firm the task of directing or coordinating production is in the hands of the owner/manager. This observation raises the question - which activities should be left to the coordinating influence of the market and which should be assumed within the firm to be controlled by management? Williamson (1971) built on this theme and identified the importance of 'transactional failures' as the driving force behind vertical integration and/or the substitution of market transactions by contracts. Transaction cost economics as described by Coase and developed by Williamson provides a solid theoretical base for the existence of a firm and for establishing the boundaries of its activities. Hobbs (1996) classified transaction costs under three major headings:
According to Coase a firm will internalize activities (vertically integrate) up to the point where the internal transaction costs associated with these activities equals the costs of using the open market. This initial research concentrated on presenting two starkly different supply chain structures for the firm - dependence on market transactions or vertical integration. The obvious question is - are there other alternatives? Transaction costs research sparked renewed interest in the relationships that exist between firms. This theme was readily taken up by academics working in other economic areas, for example, agency theory and industrial organization theory, as well as in cognate disciplines such as marketing (business to business marketing and relationship marketing) and sociology (power and conflict resolution). O'Keeffe (1994) has documented the evolution of this research. Heilbron and Roberts (1995) expanded on O'Keeffe's work and described the various forms of relationships that exist between agribusiness firms. Their study illustrated that alternative forms of organizational structure form a continuum that ranges from independence, through cooperation, coordination, collaboration, and joint ownership to integration. The intermediary stages are collectively referred to as coordination and can occur vertically or horizontally within a supply chain. Competitive advantageIn his seminal work on competitive strategy, Porter (1980) introduced the concept of a 'value stream' as a continuum of individual 'value chains'. In this model, each value chain represents an individual firm that adds value to its customer - the next firm in the value stream, and ultimately the final consumers in the target market serviced by the value stream. It follows that the total added value generated by a value stream is influenced by two factors:
In this context, what activities a firm undertakes and its relationships with other members of the value stream are of fundamental interest. According to Porter (1980), a firm's ability to create superior value for its customers - its competitive advantage, is determined by how successful it is in melding its support and operational activities. Figure 2: Porter’s Value Chain The firm's support activities consist of:
The management structures and policies of a firm are part of its intangible assets. Not only are these assets difficult to value in monetary terms they are also difficult to duplicate. Because of these characteristics, the support activities of the firm are an important source of sustainable competitive advantage. The operational activities of a firm (Porter refers to these as primary activities) consist of:
In a strategic sense, both the tangible and intangible resources of a firm constitute its strengths and weaknesses, and can be used (Wernerfelt 1984) to address some key issues such as:
This model of strategic management developed by Wernerfelt is known as the ‘resource-based view' of the firm. This view of the firm provides a logical linkage between Porter's value chain, his concept of the value stream and Coase's observations concerning the boundaries of the firm. The Porter concept of the 'value stream' provides an excellent framework within which to examine the boundaries of a firm in a strategic sense. Two aspects of these boundaries are of importance:
Figure 3: Porter’s Value Stream Evidence of horizontal integration is readily provided by the consolidation of agricultural production units across all industries over time (ABARE 1999b). Advances in technology and management have led to productivity increases that have in turn led to a reduction in the number of farms and an associated loss in the number of farmers. There has been considerable consolidation at each stage of the value stream for food and fibre products - fewer and larger processors, distributors and retailers (Australian Farm Journal 2000). As horizontal integration increases, the skills required by the owners/operators of these larger production units change. The focus shifts from operational skills to planning and coordinating skills. The term horizontal integration implies individual ownership of the enlarged operation - an implication most commonly associated with the term 'get big or get out'. But there are alternatives to individual ownership of large businesses:
Vertical integration, or common ownership of successive stages of the value stream, has always appealed to farmers as a means of increasing their access to the higher margins that they perceive to exist downstream of the farm. As we have already seen, each firm in the value stream creates value for its customer - its immediate neighbour in the value stream. By adding value the firm is able to make a profit from its activities. If a firm takes over the operations previously performed by its neighbour, then for it to be accepted by other members of the value stream it must be perceived to create at least the same value, but not necessarily in the same form, as its neighbour did previously. In other words, if a firm vertically integrates then it has to develop, or acquire, the skills needed for the success of the expanded operation. Not only is there a requirement for the development of managerial skills because of the increased complexity of the expanded business there is also a need to develop new operational skills. While the former requirement was present with horizontal integration the latter requirement usually isn't. As with horizontal integration, there are alternatives to vertical integration through ownership. The most common form is a processing cooperative - for example, similar to those that exist in the sugar and dairy industries. A more recent development in vertical coordination has been through alliances forged between customers and their preferred suppliers - the basis of supply chain management. The major contribution Porter has made through his analysis of the value chain of an individual firm is that he has clearly identified that there are multiple sources of competitive advantage within a firm. The bonus available to business managers is that if they 'get it right', in a coordinating sense, the firm's cumulative competitive advantage is enhanced. However, it is in this aspect of coordination that Grant (1996) argues that the resource-based view of the firm as promoted by Porter and Wernerfelt inadequately captures the importance of knowledge as a strategic resource.
Relationship marketingIn the previous two sections we have examined the structure of a supply chain from two different perspectives:
In this section we turn our attention to examining the relationships that exist between firms within a given supply chain as the final discipline on which supply chain management is based. The primary focus of business-to-business transactions is the exchange process. Traditionally economists and marketers have tended to treat the exchange process as a series of discrete events and as a result, relational aspects have been neglected. However there is a growing body of literature that confirms a move away from adversarial buyer-seller interaction towards a more cooperative relationship as buyers downsize their supply base and sellers tailor their marketing mix to individual buyers. This move towards greater cooperation between buyers and sellers ( referred to as relationship marketing) stems from the changes in the global marketplace and the changing requirements for competitive success (Morgan and Hunt 1994). Morris et al. (1998, p.361) define relationship marketing as
From a seller's perspective, the assumption is that it is easier and cheaper to keep existing customers than to find new ones, especially in mature and concentrated markets. Buyers see benefits arising from more reliable sources of supply in terms of total cost, delivery and quality. Dwyer et al. (1987) identifies five stages in the development of a relationship between firms:
The commitment- trust theory of relationship marketing (Morgan and Hunt 1994) postulates that commitment and trust are central to successful relationships between firms because they encourage managers to:
Further, Morgan and Hunt identify five major precursors of relationship commitment and trust which are necessary to generate these outcomes (Figure 4):
While Morgan and Hunt do not include coercive power as a variable in their model they recognize its importance as a negative effect on relationship commitment and trust that over the long-term will decrease cooperation and diminish the overall success of the relationship. Figure 4: The Morgan-Hunt Model of relationship marketing Wilson (1995) combines an expanded list of relationship variables identified by Morgan and Hunt (1994) with the stages of partnership development first proposed by Dwyer et al. (1987). In developing his five-stage process model, Wilson (p.335) argues that he is able to capture the dynamics in the development of a business-to-business relationship that are missing from cross-sectional studies.
The importance of Wilson's model is that it highlights that partners need to prioritize different relational variables depending on the current stage of their relationship. This aspect of relationship management has an even greater significance in view of the contribution of Spekman et al. (1998) to the development of relationship marketing literature. They identify (p.55) the evolving stages of a relationship between buyers and sellers that are necessary for firms to go through if they are to maximize the benefits from a strategic partnership (Figure 5).
Figure 5: The evolutionary stages of a business partnership Lorenzoni and Lipparini (1999) expand on this notion of leveraging of skills within a partnership, and in so doing create a linkage between strategic intent, the resource based view of the firm, knowledge accumulation, economic efficiency and relationship marketing. Their research, based on a longitudinal study of three networks in the Italian packaging industry generated two main propositions:
They conclude that the capability to interact with other companies – a firm's relational capacity, accelerates the lead firm's knowledge access and transfer with relevant positive effects on company growth and innovativeness. These outcomes are similar to those reported by Dyer (1996) in the US car industry. The journey from an open market, adversarial type relationship to one that involves closer collaboration with a partner requires increasing amounts of trust, commitment and relationship management. This is particularly the case in the shift from coordination to collaboration because of the necessity for greater transparency and interdependence. Empirical studies in the US (Spekman et al. 1998), South Africa (Morris et al. 1998) and Australia (Schroder and Mavondo 1998) suggest that:
Morris et al.(1998, p.369) conclude that:
They claim that this apparent gap between theory and practice may be due to:
In spite of this ‘go-slow' approach to more involved cooperation between businesses, Morris et al. (1998) think that it is reasonable to conclude that relationships are now a fixture in industrial markets. Furthermore, the literature suggests that an extension of dyadic business-to-business relationships to the whole supply chain is a prerequisite for firms wishing to compete in global markets.
In this section the theoretical foundations for the concept of supply chain management have been established. The individual elements of this foundation are not new, what is new is the integration of these elements into a management approach that has the potential to enhance a firm's competitive position in a complex global marketplace. What are the issues involved in SCM?Gifford et al. (1997, p.2) define supply chain management as:
This definition explicitly identifies innovation, efficiency and coordination as central elements of SCM and implicitly recognizes the importance of competitive strategy in aiming to meet the expectations of consumers. It is this lack of an explicit recognition of value creation as the key strategic objective of SCM that has prompted authors such as O'Keeffe (1998) and Boehlje (1999) to suggest that a more appropriate name for SCM is ‘value chain management'. To avoid confusion, the traditional terminology of supply chain management is used in this paper, but the primacy of value creation as its strategic objective is acknowledged. Perhaps the definition of supply chain management as expressed by Lambert and Cooper (2000, p.66) is more appropriate:
Porter (1980) and Wernerfelt (1984) have argued that the individual firm is the source of value creation and hence competitive advantage by virtue of its resources and processes employed to generate goods and services. Coase (1937) and Williamson (1971) claim that the activities undertaken by a firm will be determined through an comparison of the costs involved in undertaking specific production and service activities within the firms as opposed the costs (including transaction costs) of having those same activities undertaken outside the firm. Finally, the relationship marketing literature indicates that the value creation potential of an individual firm can be enhanced, in some cases, through a more collaborative relationship with its suppliers and customers (Spekman et al. 1998), provided that trust and commitment is developed (Morgan and Hunt 1994). Based on this overview of the theoretical foundations of SCM, it is possible to identify the critical issues that have to be addressed by firms contemplating becoming more proactive in the management of their supply chain so as to improve their competitiveness: Do we have the core competencies to create value?
Do we have the right competencies?Lambert and Cooper (2000) claim that a prerequisite for successful SCM is to coordinate the activities within the firm. This involves the identification of key processes undertaken by the firm and the adoption of appropriate management styles and techniques to effectively coordinate these processes. Their research, based on in-depth interviews with managers representing various levels, functions and processes in 15 different companies, identified the following key business processes:
There is an obvious correlation between this list of processes and those identified by Porter (1980). Lambert and Cooper (2000) assert that cross-functional teams best manage these intra-firm processes and they identified the fundamental components of management required for success: Managerial and behavioral components
Physical and technical management components
By integrating these observations with those of other researchers such as Spekman et al. (1998), Lendrum (1998), Fearne and Hughes (1999), Morgan and Hunt (1994) and O'Keeffe (1998) it is possible to construct a checklist that can be used by the management of a firm to assess its readiness to partner (Table 1). No attempt has been made to prioritize the components of the checklist or to set any minimum score that is indicative of a firm's readiness to partner. The use of Likert Scales is a way of identifying the firm's strengths and weaknesses in relation to the key relationship success variables that were gleaned from the literature. Table 1 Readiness to Partner Profile
How do we select the right partners?Spekman et al.(1998) clearly indicate that closer business-to business relationships such as cooperation and integration are neither appropriate nor desirable in all situations. This raises two questions in the context of SCM:
Fortunately the research of Lambert and Cooper (2000) provides some answers. They contend that all firms belong to a supply chain, but the structure of this supply chain resembles an uprooted tree rather than a simple linear sequence of independent businesses. (Figure 6) Figure 6: A Supply Chain Network Structure Even in this simple representation of a firm's supply chain network it is obvious that a firm has multiple relationships with other firms and that the firm belongs to many supply chains. From a supply chain management perspective Lambert and Cooper claim that it is important to identify which members of these supply chains are critical to the success of the focal firm and therefore should be allocated appropriate managerial attention and resources. These strategic firms become the ‘primary' members of the supply chain (shown as shaded boxes in Figure 6) and the remaining firms comprise the ‘support' firms within a particular chain. (The business-to-business relationships that need to be managed or monitored by the focal firm are indicated by the heavy lines.) Another important consideration arising from this network analysis is that suppliers or buyers may not view the relationships shown to be important from the focal firm's point of view in the same light. As Lambert and Cooper (2000, p.72) point out:
This observation reinforces the importance of the ‘awareness' and ‘exploration' phases of the relationship development model proposed by Dwyer et al.(1987) in partner selection. Again drawing on the literature it is possible to construct a checklist to aid the management teams of potential partner firms to evaluate each other. In Wilson's (1995) Partner Selection phase six relationship variables are identified as important. These correspond closely with the five antecedent variables identified by Morgan and Hunt (1994) and O'Keeffe's (1998) foundation variables. (Table 2) Table 2 A Comparison of Relationship Variables in the Partner Selection Phase
The starting point for this partner evaluation process is the checklist developed to assess the individual firm's readiness to partner (Table 1). There are two ways in which the Readiness to Partner checklist can be used:
Whipple and Frankel (1998) highlight the importance of partner match as one of the five variables that determine the strategic effectiveness of an alliance and the use of the Readiness to Partner profiles seem to be an effective means of measuring this. In addition, Whipple and Frankel (1998) claim that the operational effectiveness of an alliance is in part determined by the partners' propensity to commit that is based on mutual commitment to problem resolution and the presence of competence based trust. In summary, the selection of a partner/s has three basic components:
These components provide the framework for the Partner Selection checklist shown in Table 3. As with the Readiness to Partner checklist, there has been no attempt to weight individual components or items in the Partner Selection checklist. It is acknowledged, as Whipple and Frankel (1998) point out, that it is difficult to achieve integration between firms' corporate philosophies and culture in the absence of character-based trust – as measured by the components of cultural compatibility. Again, the use of Likert Scales allows the generation of a Partner Compatibility profile which can assist the management of the firms involved in deciding to proceed with the alliance or not. Setting the boundaries to a partnershipThe ability of the partnership to create superior customer value is of strategic importance. As part of the process of determining the potential for value creation the partners have to consider what processes within each of the individual firms need to be coordinated across the supply chain partners. Lambert and Cooper (2000) identified eight key supply chain processes and the results of their research demonstrated that not all these processes need to be managed across the entire supply chain. For example, customer relationship management may require coordination across the chain as might manufacturing flow management, while integration of customer service management might be restricted to a particular buyer –seller relationship. The identification of which business processes need to be managed and the extent of the integration of these processes between firms can be achieved by mapping the individual processes through the supply chain network. The result of this process mapping would produce an outcome similar to that of the network mapping shown in Figure 6. The purpose of this process mapping exercise is to identify the key processes that require managerial attention so that firms' resources can be allocated efficiently and effectively. Table 3 Partner Selection Checklist
Performance evaluationAs Morgan and Hunt (1994) pointed out, the strength of a relationship is based on trust and commitment but without trust there will be no on-going commitment to the relationship. The research of Whipple and Frankel (1998) demonstrated that the two component of trusts, character-based trust (integrity, openness, reliability) and performance-based trust (technical and business competence) are built over time and are based on a measure of outcomes versus expectations. Increasing levels of trust encourage the partners to invest more in the relationship. O'Keeffe (1998) reminds us that these investments can be in terms of people, time, reputation, information, processes or capital and that over time they lead to a position of interdependency. O'Keeffe (1998) refers to this process as the Investment Trust Cycle (Figure 7). Figure 7: The Investment Trust Cycle The question remains – how do we evaluate the performance of a relationship? Firms enter strategic partnerships because they believe that they will be ‘better off' by working more closely with selected members of their supply chains. The expectations of these mutual benefits are determined in the exploration stage of the relationship development model identified by Dwyer et al. (1987). It is during this stage that Wilson (1995) claims that the success or failure of a relationship is determined as partners align their mutual goals and define the boundaries of their relationship. These two key processes initiate trust and determine the resources available to create value in the relationship. Lendrum (1998), O'Keeffe (1998), van Hoek (1998), Whipple and Frankel (1998) and Fearne and Hughes (1999) have developed key performance indicators by which partnerships can be evaluated. (Table 4) Table 4 Key Relationship Performance Indicators
The Partner Selection checklist (Table 3) provides a benchmark for the subsequent evaluation of the partnership since it presents a profile of the firms' perceptions of each other in terms of their cultural, strategic and process compatibility at the commencement of their partnership. The elements of this checklist cover the key performance indicators shown in Table 4, therefore it is appropriate to use them in the construction of a Partnership Evaluation checklist (Table 5). The cultural compatibility components of the Partnership Evaluation checklist have been retained from the Partner Selection checklist. These key aspects of a firm's culture do not change but we would expect to observe an increase in alignment of the partners' cultural compatibility as the length of the partnership increases. The second section of the Partnership Evaluation checklist concentrates on producing a profile that reflects the partners' perceptions of the performance of the partnership in meeting their expectations. Of course it is assumed that the partners would have developed quantitative measure of performance, wherever possible, to underpin these perceptions. Table 5 Partnership Evaluation Checklist
