LOGISTICS LEVERAGE Donald J. Bowersox Michigan State University East Lansing, MI John T Mentzer The University of Tennessee Knoxville, TN Thomas W Speh Miami University Oxford, OH Abstract It is the purpose of this paper to position marketing and logistics rela- tionships in a strategic context. The strategic position of both areas is used to draw conclusions for the future relationships of marketing and logistics and to suggest the need to focus on creating "logistics leverage." Logistics leverage - the ability to achieve marketing advantage through logistics superiority - is accomplished through the resolution of nine key issues. Once resolved, logistics can be exploited to obtain and maintain significant competitive advantage. Introduction Much recent attention in both business and research has been devoted to the importance of interfunctional coordination (Crittenden 1992; Deshpande and Webster 1989; Kahn and Mentzer 1994; Lichtenthal and Wilson 1992; O'Reilly 1991; Ruekert and Walker 1987; St. John 1991; St. John and Hall). Two areas that have received particular scrutiny have been marketing and logistics (Granzin 1980; Granzin and Bahn 1989; Mentzer 1993; Rinehart, Cooper, and Wagenheim 1989; Voorhees and Coppett 1986; Voorhees, et. al. 1988). The objective of this paper is to examine the relationship between marketing and logistics within a stra- tegic context. This examination is developed in four parts. In the first part, two catalysts to further integration of marketing and logistics are discussed. In the next part, the integration of marketing and logistics is projected into a strategic context. The third part introduces the concept of logistics leverage and the nine issues that must be resolved to accomplish it. Finally, conclusions for marketing and logistics managers and researchers are presented. Spring 1995 Mentzer, et. al.: Logistics Leverage 37 Marketing/Logistics Integration Catalysts Although marketing and logistics often receive some degree of integra- tion, two catalysts existing in the business environment are working to make lo- gistics superiority, and its strategic integration with marketing, a necessity for many companies. Understanding these catalysts better positions how logistics can be deployed as a key strategic resource. Time and Quality Based Competition Time and quality based competition focus on eliminating waste in the form of time, effort, defective units, and inventory in manufacturing-distribution systems (Larsen and Lusch 1990; Schonberger and EI Ansary 1984; Schultz 1985). The most popular time and quality based concepts are just-in-time (JIT) and quick response (QR). JIT has many facets and touches almost all aspects of a business enter- prise (Bartholomew 1984; Daugherty and Spencer 1990; Frazier, Spekman, and Oh 1987; Jackson 1983; Rosenberg and Campbell 1985). As a result, purchas- ing, transportation, inventory, and manufacturing personnel all consider JIT to be indigenous to their performance (Yanacek 1987). In reality, all these activities, plus marketing, are impacted by the adoption of a JIT system within which lo- gistics becomes the focal point of implementation. One of the effects of JIT is to direct logistics attention toward an over- all procurement, manufacturing, operating, and marketing orientation of the busi- ness. Importantly, there are significant marketing benefits that can result from establishing JIT competency - for example, higher customer satisfaction from better quality products with zero defects, more consistent availability, and faster prod- uct delivery. Typically, such benefits are fully exploited only if logistics manag- ers are more attuned to internal, supply-side systems and cost control, while in- tegrating with marketing programs and customer requirements. Quick Response (QR) systems are similar to JIT programs (i.e., the re- quired integration of marketing, purchasing, transportation, inventory, and manu- facturing), but differ by the fact that they deal with the distribution of finished products from manufacturers to wholesalers and retailers (Larsen and Lusch 1990). Many of the principles of successful QR are similar to the logic that drives JIT. Because QR typically deals with finished product distribution, performance is an integral part of total customer service (Dumaine 1989). However, the drivers that make most existing QR programs successful are inventory velocity and total cost reduction. Only a limited number of firms have begun to manage QR programs toward the goal of achieving competitive advantage (Daugherty and Spencer 1990). The competitive impetus for such coordination of inventory velocity and cost con- trol with customer satisfaction serves as a catalyst for marketing/logistics inte- gration in finished goods channels. More advanced forms of QR, however, focus primarily on customer sat- isfaction. Recently coined "Service Response Logistics" (Davis and Manrodt 1991 and 1993; Manrodt and Davis 1992), these programs tend to position logistical 38 Journal of Business Strategies Vol. 12, No.2 competency as the core activity aimed at achieving customer satisfaction through inventory availability, timely delivery, less product failure, and, thus, less lost sales or returns/complaints (Stalk, Evans, and Shulman 1992). The achievement of such customer satisfaction requires significant integration of logistical competency and marketing performance. The combined effect of time and quality based systems has been to em- phasize the need for marketing/logistics integration as a competitive advantage. While both JIT and QR thrive on interorganizational and interfunctional coordi- nation, such arrangements must be driven by a desire to reduce cost, improve asset utilization, and more effectively service customers. Attention to service response logistics suggests that some significant break-throughs that capitalize on the strategic impact of marketing/logistics integration are developing. Efficiency and Effectiveness Logistics, by its nature, is quantitative in the measurement of efficiency Delivery time, the number of short orders, inventory, and similar operational activities can be readily measured. As a result, logistics practice and research has been more operationally oriented and tended to focus more on economic or efficiency measures of performance. The absolute magnitude of logistics cost has directed many firms to control the expense side of logistics; that is, to manage the process to achieve a level of efficiency. Although there has been considerable research in the logistics area con- cerning how logistics impacts customer service (for a review, see Mentzer, Gomes, and Krapfel 1989), no accepted protocol for measuring customer responsiveness to logistics service levels exists. Further, the traditional focus of logistics research on economic (efficiency) issues rather than behavioral issues has not brought the attention of behaviorr.l researchers in marketing to bear on this problem. Although much research in marketing has been devoted to the behavioral implications of service quality and customer satisfaction/dissatisfaction (for a review, see Zeithaml, Berry, and Parasuraman 1993), little such research has addressed the behavioral implications of changes in logistics service quality as part of overall marketing strategy (Mentzer, Bienstock, and Kahn 1993). However, cost control (efficiency) without recognition of customer ser- vice requirements (effectiveness) will doom any aspect of a marketing effort to failure. Logistics is no exception. The need for a clearly defined linkage be- tween logistics performance, marketing strategy, and their behavioral consequences provides the second, and perhaps most important, catalyst for the implementation of logistics as a strategic marketing tool. Summary Current developments in the business environment and the marketing lit- erature suggest these catalysts are having an impact. There are increasing ex- amples of firms such as Wal-Mart, Target, and K-mart establishing alliances with manufacturers to jointly reduce costs and leverage performance. Further, the Spring 1995 Mentzer, et. al.: Logistics Leverage 39 recent interest in the marketing literature with relationship marketing (Anderson and Weitz 1992; Anderson and Narus 1990; Dant and Schul 1992; Dwyer, Schurr, and Oh 1987; Frazier, Spekman, and O'Neal 1988; Heide and John 1992; Larsen and Lusch 1990) suggests progress in examining the strategic management of logistics issues in building relationships with customers. Results of such alliances and research scrutiny suggest that issues of efficiency and effectiveness measure- ment can be jointly resolved and that logistical performance can be integrated into mainstream marketing strategy and research. The reality of such catalysts and the potential to be gained from them argue strongly for in-depth examina- tion of logistical effectiveness in overall marketing strategy and a searching con- sideration of the key role that logistics plays in creating customer satisfaction. The Marketing/Logistics Strategic Linkage In Porter's (1985) value chain, one of the four support activIties (pro- curement) involves logistics and all of the five primary activities involve logis- tics (inbound logistics, operations, and outbound logistics), marketing (marketing activities), or both (service). It is interesting to note how these functions are so important and inextricably linked in the value chain and suggests that increased focus be placed on effectively coordinating their interaction. The foundation of future marketing and logistics integration is strategic. With this goal in mind, Figure 1 utilizes the competitive advantage framework of Day and Wensley (1988) to develop the dimensions of the relationship and position the strategic importance of integrated marketingllogistics. The focus of logistics has been and will primarily continue to be upon cost drivers, i.e. skills and resources that generate efficiency. The integration of marketing and logistics is necessary to bring the logistics sources of advantage into the realm of effectiveness, or drivers of differentiation. This will only oc- cur and result in positional advantages if the leverage logistics can bring to mar- keting is realized. This leverage can only be realized by recognizing and ex- ploring, both within the practitioner and academic communities, the strategic link- age between marketing and logistics wherein logistics skills and resources are translated into effective drivers of differentiation. Where this integration is ac- complished, strategic positioning of the marketingllogistics integrated firm as cost efficient and customer effective will result. It will be incumbent upon market- ing to emphasize these superior performance outcomes to achieve sustainable competitive advantage. Firms that have successfully implemented such coordination are now building corporate strategies that exploit logistics competency (Bowersox, el. al. 1991). By focusing on logistics competency (e.g., one call for complete order status information, total flexibility in ordering to support either store direct or warehouse delivery, no order minimums), the leading logistics performers are providing tangible and significant benefits to customers. The net result is the creation of a meaningful competitive advantage. 40 Journal of Business Strategies Figure 1 Integrated Strategic Planning Vol. 12, No.2 MARKETING FOCUS EFFECTIVENESS Superior Skills Superior Resources LOGISTICS FOCUS EFFICIENCY Superior Skills Superior Resources I Catalysts to Integration I INTEGRATION FOR SUPERIOR CUSTOMER VALUE AND LOWER RELATIVE COSTS + STRATEGIC POSITIONING LOGISTICS LEVERAGE + PERFORMANCE OUTCOMES t COMPETITIVE ADVANTAGE Selected finns are beginning to realize that logistics excellence is a sig- nificant differential advantage that can be exploited in the marketplace (Bowersox et. al. 1991). Logistics service is an effective tool for building closer relation- ships with key customers. Although the expression "being easy to do business with" is over used, the fact remains that some finns are very difficult to buy products from and have poor response systems for providing infonnation concern- ing such facts as order status and invoice discrepancy. Other finns have state- of-the-art logistics infonnation systems that enable maximum control (Shapiro, Spring 1995 Mentzer, et. al.: Logistics Leverage 41 Rangan, and Sviokla 1992; Stalk, Evans, and Shulman 1992) - a source of ad- vantage which can be translated through integration with marketing into a posi- tional advantage (Day and Wensley 1988). The result is the performance out- come of significant customer impact. The final outcome of these superior logis- tics systems is an added positional advantage of preferred status for selected suppliers - and such status draws directly from the logistics competency (even in situations where price, product, and promotion are undifferentiated or marginally higher in comparison to selected competitors). As Day and Wensley (1988) observed, "The sustainability of this posi- tional advantage requires that the business set up barriers that make imitation dif- ficult." The true positional advantage of logistics competency is that a Chief Executive Officer cannot, by the whisk of a pen, mandate such competency and automatically obtain the facilities, systems, human resources, and information con- trol necessary to produce a consistent level CI' logistical performance. As mar- keting strategies evolve toward greater market segmentation sophistication, the abil- ity to provide customized logistics service to unique segments will become in- creasingly demanding. Firms with high levels of logistical competence are bet- ter positioned to exploit such opportunities. Logistics Leverage The critical question is how to leverage the strategic benefits inherent in an effective logistics system for maximum competitive advantage. Logistics le- verage is the ability to effectively influence market demand through the applica- tion of excellent logistics systems, techniques, and programs. The term leverage indicates relatively high market returns may be gained from relatively small in- vestments. Significant sales, market share, and consumer satisfaction gains can be achieved if the firm consciously positions itself to leverage its logistics capa- bilities. It is not enough to have created the human resources, technical tools, and operational systems for effective logistics, the firm must be able to market and use its logistics expertise to achieve marketing goals. Thus, logistics lever- age is based upon successfully resolving nine issues. Creation of Value-Added Services The exploitation of logistics competence offers a meaningful way to cre- ate value-added services not achievable in other ways (Cooke 1990; Mentzer 1993; Wittersdorf 1991). Such positioning requires defining critical business processes from a logistics perspective. Such value-added processes have spawned the de- velopment of new channel institutions. Logistics facilitation companies are one of the most rapidly growing marketing institutions. Such facilitators do not view themselves as traditional wholesalers, retailers, warehousers, or transportation com- panies. Their mission vision is one of being a service organization which satis- fies a specific niche requirement. They provide logistics economies of scale, es- sential services, and time and quality based delivery. 42 Journal of Business Strategies Vol. 12, No.2 The combination of more effective delivery at a lower cost translates to increased value. Thus, what have traditionally been logistics cost drivers are be- coming drivers of differentiation (Day and Wensley 1988; Porter 1985). Again, the shift from cost driving logistics activities to logistics drivers of differentia- tion requires the integration of marketing and logistics activities and strategic plans. Management Vision Top management must fully understand the real and significant market impact that results from logistics superiority. Recent history has demonstrated that many of the successes achieved by large consumer goods firms with mass merchandisers resulted from the manufacturer's ability to lower iogistics costs while increasing logistics service, resulting in increased final consumer satisfac- tion combined with reduced retailer inventory. These drivers of differentiation were accomplished through management's vision of the potential of logistics and a commitment to leveraging their logistics system for their customers. Management vision will achieve logistics leverage only if (1) top man- agement applies resources to bring logistics expertise to their customers on a cus- tomer-by-customer basis (Davis and Mandrodt 1991), (2) the attitude of market- ing customer satisfaction as a corporate core competency is nurtured by top man- agement throughout the entire organization, not just in marketing, and (3) the lo- gistics benefits of the manufacturer are communicated directly from the supplier CEO to the customer CEO. This latter point is an essential ingredient in the establishment of strategic alliances and partnerships. Strategic Alliances and Partnerships The marketing value of exploiting logistics competency is demonstrated by the positional advantage available as a result of linking firms and their cus- tomers into strategic alliances and partnerships. The last decade has witnessed the growth of vertically-integrated marketing systems in a behavioral or relational sense (Dwyer, Shurr, and Oh 1987; Frazier, Spekman, and O'Neal 1988; Narus and Anderson 1986). The strategic alliances that have evolved are broader in scope than simple out-sourcing because they include risk and reward sharing. A significant aspect of these newly created alliances is the central role typically played by logistics (Bowersox 1990). Inventory management, direct- store delivery, warehousing, and transportation consolidation are typical logistics functions that are at the core of many partnerships. The efficient performance of these activities by specialists produces benefits shared by both partners. As Frazier, Spekman, and O'Neal (1988, p. 53) stated, the emphasis in such rela- tionships is on "the notion of 'total cost of ownership' and the array of value- added services provided." Strategic Interfunctional Teams Logistics superiority as a driver of differentiation can be achieved only when all parties in the marketing organization are integrated in terms of the ba- Spring 1995 Mentzer, et. al.: Logistics Leverage 43 sic concept of customer satisfaction, the potential of logistics leverage to aid in obtaining customer satisfaction, how the message of logistics customer value needs to be communicated, and to whom this message should be delivered. Team mar- keting approaches, typically composed of marketing, sales, logistics, finance, and production representatives, are common place and the norm in some industries, with significant resultant advantages (Hun and Speh 1984). To achieve logistics leverage, marketing must recognize the role logistics plays in achieving customer satisfaction. Without this recognition, the related promotional, pricing, and "ser- vice package" strategies to market logistics expertise to the customer will not be achieved. It falls to logistics to develop and deliver the logistics excellence that marketing has identified as important to customers. Orientation of Marketing For many firms, particularly in the consumer goods industries, the over- riding emphasis in marketing personnel training is given to the product and pro- motional dimensions of marketing strategy. Many factors reinforce this orienta- tion: brand manager organizations; college marketing curricula with an empha- sis on advertising, promotion, and product development; and corporate training programs where marketing personnel are given little exposure to logistics. To achieve logistics leverage, colleges and corporations need to rethink the manner in which marketing managers are developed. One step that can be taken by colleges in this leadership role is to make logistics courses required for all busi- ness students. Organizational Issues A major premise of this work is that logistics competency can be cre- ated, but unless the firm is positioned to exploit it, little strategic significance will result. One way to leverage logistics excellence is to establish hierarchies and reporting relationships that maximize the integrated potential. When mar- keting, sales, and logistics each report to a separate vice president, each with their own organization, more effort will be required to break down the inherent orga- nizational barriers so that integration is achieved. Customer teams and matrix management are commonly used to overcome organizational inflexibility (Clark and Wheelwright 1992; Gibson, Ivancevich, and Donnelly 1988; Lawrence, Kolodny, and Davis 1977). However, since logistics is a customer satisfaction impacting function and its significance as a competi- tive marketing tool has been demonstrated, logistics should logically be more closely aligned organizationally with marketing. Rather than a team approach, if logistics reports directly to marketing, the potential for maximum market impact of logistics leverage is increased. Market Intelligence To achieve logistics leverage, information systems need to be restructured so that new and different types of information are routinely gathered and sup- 44 Journal of Business Strategies Vol. 12, No. 2 plied to the marketingllogistics function. Information on customer logistics prob- lems and opportunities are required so the firm can quickly adapt their logistics expertise to meet these challenges. Market research needs to expand from the traditional study of needs, attitudes, and behavior related to product, price, and promotional offerings to include the study of customer logistics needs that cus- tomers may not even be aware exist. In addition, environmental assessment stud- ies to benchmark the efforts of those firms deemed to be leaders in logistics excellence will supply strategic information relative to the firm's existing logis- tics offering. Channel Member Programs To effectively exploit logistics competence, significant efforts may be re- quired to upgrade the logistics systems of other channel members. All channel members must share the vision of the potential market impact of logistics excel- lence. Without that vision, there will be little hope of developing a marketing program with a logistical focus. Further, logistics leverage can only be achieved in market segments served by channel members when those members possess the level of logistics excellence required by those customers. This excellence can be developed by careful selection of channel members by market segment, by transferring logistics excellence through strategic alliances, or out-sourcing cer- tain traditional channel functions to third party providers. Sole-Source Relationships Finally, the last several years have witnessed increasing efforts by firms to reduce their supplier base and move into sole-source relationships with key suppliers (Bertrand 1986; Frazier, Spekman, and Oh 1988; Purchasing 1989). This trend underscores t,e need to refocus strategic thinking on the role logistics can play in establishing sole-source relationships. Because of the impact of a vendor's logistics competence on the buyer's costs and operations (just-in-time delivery to production sites, damage-free products, error-free orders, and real-time informa- tion are all cost drivers that are potentially also drivers of differentiation for the firm), the vendor's logistics system may be the most effective way to create and support a sole-source relationship. Conclusions The relationship between the related, but often independently managed, functions of marketing and logistics has been examined. The strength and lon- gevity of the positional advantage from logistics excellence is impressive because of the difficulty of duplicating outstanding logistics systems and the significant benefits they provide to customers from a cost and quality standpoint. Logistics leverage has to be consciously created through the actions of marketing and logistics managers within the firm. Key issues to be resolved in- clude the creation of value-added services, top management vision, strategic alli- Spring 1995 Mentzer, et. al.: Logistics Leverage 45 ances and partnerships, interfunctional teams, the orientation of marketing, orga- nization structure, marketing intelligence, channel member programs, and the nur- turing of sole-source relationships. Once these issues are resolved, the firm will be positioned to effectively integrate logistics competence into marketing strat- egy to create sustainable differential advantage. Future research and management issues are very much related to the ef- fort to create logistics leverage. Managers and researchers alike need to become more concerned with the buyer behavior implications of changes in the market- ingllogistics customer service package. Buyer attitudes and behavior can be ex- pected to change with integrated marketing/logistics efforts (Mentzer, Bienstock, and Kahn 1993). Whether this altered behavior will be for the good or detri- ment of the company, and in what degree, lies within the realm of buyer behav- ior and service quality research - both applied and academic. Measurement issues should continue to occupy the attention of research- ers. Without valid models and predictions of logistics impact on sales, costs, and profits, it is difficult to successfully plot the most meaningful role for logistics in the strategic thrust of a firm. More effective models are needed at two lev- els: within the channel and at the point of sales to the consumer. Logistics service (in-stock levels, order cycle time, etc.) interacts with a variety of other marketing variables (price, boundary person relationships, location, brand name, advertising claims, etc.) to determine the customer's satisfaction. It will be nec- essary to expand research efforts to measure these interactions and isolate the specific effect of each variable. Once these effects are better understood, mar- keting decision-making will be better positioned to make more effective decisions regarding the strategic positioning of logistics services within the overall market- ing offering. The arenas of logistics and channels have long followed separate pre- dominant paradigms - economic for logistics and socio-psychological for chan- nels. However, both areas of marketing address the same marketing phenomena - distribution of products. The channels area typically addresses negotiation be- tween channel members, whereas the logistics area addresses the operational in- teraction between these channel members. These two areas are not separate and cannot be meaningfully managed or researched without recognition of their in- teraction. The effect of negotiation upon operational reality and vice versa would seem a topic with rich potential for research and managerial creativity. In par- ticular, the application of the transaction cost analysis paradigm (Mcneil 1980; Williamson 1975 and 1985) to the effect of logistics transaction specific invest- ments upon negotiation behavior would seem to be a research area immediately ripe for investigation. Also within the TeA paradigm, an area of increasing importance is the role of third-party logistics suppliers. Effective logistics competency may be en- hanced through the utilization of independent suppliers of a wide array of value- added logistics services. Research, grounded in the transaction cost analysis para- digm, to evaluate the efficiency and effectiveness of out-sourcing logistics func- 46 Journal of Business Strategies Vol. 12, No.2 tions would help develop the dimensions of how logistics can contribute to maxi- mum strategic impact. By out-sourcing some logistics functions (e.g. warehous- ing), a firm may gain cost and service advantages not available from internal performance, but incur additional transaction specific investments. As a result, the enhanced level of performance may create a differential advantage that oth- erwise would not have existed, but come at the cost of increased dependence upon a third party. Being aware that an enhanced performance level is possible at the cost of increased risk permits decision-makers to more effectively assess the con- tributions of logistics to overall marketing success.
