A global exploration of Big Data in the supply chain Robert Glenn Richey Jr Department of Systems and Technology, Auburn University, Auburn, Alabama, USA Tyler R. Morgan Department of Supply Chain and Information Systems, Iowa State University, Ames, Iowa, USA Kristina Lindsey-Hall Department of Marketing, University of Alabama, Tuscaloosa, Alabama, USA, and Frank G. Adams Department of Marketing, Mississippi State University, Starkville, Mississippi, USA Abstract Purpose – Journals in business logistics, operations management, supply chain management, and business strategy have initiated ongoing calls for Big Data research and its impact on research and practice. Currently, no extant research has defined the concept fully. The purpose of this paper is to develop an industry grounded definition of Big Data by canvassing supply chain managers across six nations. The supply chain setting defines Big Data as inclusive of four dimensions: volume, velocity, variety, and veracity. The study further extracts multiple concepts that are important to the future of supply chain relationship strategy and performance. These outcomes provide a starting point and extend a call for theoretically grounded and paradigm-breaking research on managing business-tobusiness relationships in the age of Big Data. Design/methodology/approach – A native categories qualitative method commonly employed in sociology allows each executive respondent to provide rich, specific data. This approach reduces interviewer bias while examining 27 companies across six industrialized and industrializing nations. This is the first study in supply chain management and logistics (SCMLs) to use the native category approach. Findings – This study defines Big Data by developing four supporting dimensions that inform and ground future SCMLs research; details ten key success factors/issues; and discusses extensive opportunities for future research. Research limitations/implications – This study provides a central grounding of the term, dimensions, and issues related to Big Data in supply chain research. Practical implications – Supply chain managers are provided with a peer-specific definition and unified dimensions of Big Data. The authors detail key success factors for strategic consideration. Finally, this study notes differences in relational priorities concerning these success factors across different markets, and points to future complexity in managing supply chain and logistics relationships. Originality/value – There is currently no central grounding of the term, dimensions, and issues related to Big Data in supply chain research. For the first time, the authors address subjects related to how supply chain partners employ Big Data across the supply chain, uncover Big Data’s potential to influence supply chain performance, and detail the obstacles to developing Big Data’s potential. In addition, the study introduces the native category qualitative interview approach to SCMLs researchers.

Introduction “Big Data” is industry’s hottest buzzword (see Waller and Fawcett, 2013). Consultants proclaim that Big Data will revolutionize industry and decision making. Current investments suggest Big Data’s importance: International Data Corporation “predicts that the market for Big Data will reach $16.1 billion in 2014, grow six times faster than the overall IT market[1].” Still, some practitioners fear that Big Data’s value is exaggerated and view it as little more than an extension of forecasting or traditional marketing research. Unfortunately, as is the case with many hot topics and buzzwords, supply chain research with useful implications is lacking. “[T]here is very little published management scholarship that tackles the challenges of using such tool; or better yet, [that] explores the promise and opportunities for new theories and practices that Big Data might bring about” (George et al., 2014, p. 321). In fact, there is almost no consistency in defining Big Data, identifying its purpose, or establishing its role in supply chain management. Thanks to a grant from the Council of Supply Chain Management Professionals, we seek answers to questions about whether supply chain partners employ Big Data in supply chain strategy, the theoretical origins of Big Data’s potential to influence supply chain performance, and the obstacles to developing its potential. Given the scarcity of research on Big Data as a supply chain construct, it is well suited to qualitative exploration. The strength of qualitative research is that it provides insights regarding difficult-to-perceive issues in supply chain management and logistics (SCMLs) (Mangan et al., 2004; Näslund, 2002). Estimates of the use of qualitative methods in SCM research vary widely. Golicic and Davis (2012) note that “[.] the reported frequency of studies using qualitative methods varies a great deal; this is likely due to the different journals included in the different reviews. One review reports qualitative methods in as few as 10 percent of the articles, and one finds 51 percent of the studies they examined to use qualitative methods (this particular study included any journal in which ‘supply chain management’ was a subject of the article)” (p. 729). However, Fawcett and Waller (2011) estimate that only 10-20 percent of published articles in SCML embrace qualitative methods. In general, qualitative research is considered effective in addressing the “how” questions regarding processes being studied (Pratt, 2009). The questions posed here stem from a need to better understand Big Data’s role in supply chains (George et al., 2014), and this study describes the qualitative method used to examine those questions. The research then explores subjects’ comments to determine how closely their views correspond to extant – if ill-defined – definitions of Big Data. Further, we examine how supply chain managers use Big Data to expose Big Data’s key success factors and enablers in supply chain management. The key success factors and enablers described here suggest that Big Data, as a supply chain construct, should be characterized as structured and unstructured relationship-based information unique to its holder because of the information’s volume, velocity, variety, and veracity. Further, while such a definition might imply that Big Data is no more than an undifferentiated resource, the responses explored here also suggest that the collective abilities to assemble and leverage Big Data constitute a firm’s dynamic capability (DC). Research questions The discussion of“what” Big Data “is” remains incomplete. Industry provides no complete and specific definition. Popular literature discusses volume, velocity, variety, and veracity, but gives limited definitions of each. Supply chain managers remain confused about Big 711 Global exploration of Big Data Downloaded by Huazhong University of Science and Technology At 22:37 29 November 2016 (PT)

Data’s creation and sourcing (Richey et al., 2015). This study treats Big Data as both strategic and operational, so our first step was to develop an understanding of what supply chain managers think Big Data is from their perspective. This definition must be confirmed before accurate future research can be performed (Richey et al., 2015). A lack of clear, easily understood terms has long challenged supply chain researchers. For example, the word “agility” is used to mean “adaptability,” “flexibility,” “slack,” and “improvization” (Gligor and Holcomb, 2012; Golicic and Sebastiano, 2011). From a relationships perspective, it is nearly impossible for managers to collaborate when they lack a consistent interpretation of common terms. Council of Supply Chain Management Professional’s (CSCMP) list of acronyms, as well as the use of Incoterms, are prominent examples of managing and simplifying terminology. Overall, it is important to reach consensus regarding a definition of “Big Data” in SCML relationships. We should derive this definition through a management perspective rather than from a commercial organization perspective because the latter’s goal is to entice firms to purchase their products and services in hopes of unlocking Big Data’s potential performance. Following a basic conceptualization (or perhaps re-conceptualization) of Big Data, we seek to develop an initial understanding of Big Data’s future in supply chain strategy and operations. From a best practices perspective, managers often ask about the key success factors to making relationship-based processes work (Fawcett and Magnan, 2002; Richey et al., 2010). At the onset of new supply chain initiatives, managers assess existing capabilities and options. So, the next task is uncovering Big Data-related, performance-based, key success factors. Categorizing, assessing quality, and identifying Big Data’s impact is very new to management in general (George et al., 2014). Managers hope supply chain relationships will create synergy that allows firms to increase revenue and/or reduce costs beyond what a single firm can accomplish. Thus, while it is important to understand opportunities, it is equally important to understand potentially negative consequences that may reduce or eliminate firm and joint-firm performance. Though essential to supply chain management, software developers and managers often overlook these dynamics because they are embedded in technology departments with limited boundary-spanning opportunities. Our study addresses these research questions: RQ1. How does Big Data impact supply chains? RQ2. What are the key success factors for Big Data implementation in SCML? RQ3. What theory best explains the potential long-term value Big Data can bring to supply chain partnerships? This study uses a lived experience qualitative interview technique to address these very broad questions. These open-ended questions are intentionally general and provide limited structure to allow respondents to answer at length, thus reducing interviewer bias. We discuss this method briefly in the following section. Next, we discuss our industry-based results and conclusions from a global perspective, including China, Germany, India, South Korea, Turkey, and the USA. Research method We used a native category approach in our research methodology. Often used in sociology and anthropology research, the native categories approach avoids interviewer 712 IJPDLM 46,8 Downloaded by Huazhong University of Science and Technology At 22:37 29 November 2016 (PT)

In line with naturalistic views (Lincoln and Guba, 1985),this studyemployspurposive sampling (Kuzel,1992)and reputational case selection(Goetz andLeCompte, 1984), seeking out subjects likely to have a rich understanding of ourphenomenon of interest, but withvaried perspectives.Purposive sampling is often usedinqualitativeresearchwhenthesubjectsselectedpossessexperiencecongruentwiththeresearchobjective(Guestetal.2006).UsingtheCSCMIPmembershiprosterandknownindustryparticipants,weidentified managers from several countrieswho areknown forusing information technology across supply chain relationships.Wesoughttodevelopabreadthofunderstandingacrossseveral countries.Assessing academic research, popular press articles, and industry participants'locations,we identified nine countries:Brazil, China, Germany,India, South AfricaSouth Korea, Turkey, the UK, and the USA.

historical bias by sequentially and increasingly removing the interviewer from direction of the interview process (Harris, 2000). The approach is designed to force respondents into open-ended discussions with the interviewer, centering future questioning on the key comments made by the respondent. This method of qualitative research proves especially valuable and appropriate when the phenomena studied are not precisely understood, as well as when the researcher needs to draw perspective from subjects experiencing the phenomena (Corbin and Strauss, 2008). This allows relevant factors to emerge from the data. In line with naturalistic views (Lincoln and Guba, 1985), this study employs purposive sampling (Kuzel, 1992) and reputational case selection (Goetz and LeCompte, 1984), seeking out subjects likely to have a rich understanding of our phenomenon of interest, but with varied perspectives. Purposive sampling is often used in qualitative research when the subjects selected possess experience congruent with the research objective (Guest et al., 2006). Using the CSCMP membership roster and known industry participants, we identified managers from several countries who are known for using information technology across supply chain relationships. We sought to develop a breadth of understanding across several countries. Assessing academic research, popular press articles, and industry participants’ locations, we identified nine countries: Brazil, China, Germany, India, South Africa, South Korea, Turkey, the UK, and the USA. Based on existing qualitative interview conventions, we set a goal of acquiring a minimum of three interviews in each country. Sampling and data collection Subjects in Brazil, Germany, South Africa, and the UK were reluctant to discuss company strategy, so we augmented our sample by using a comparable case approach (Goetz and LeCompte, 1984) and solicited members to volunteer contact information of other executives qualified to participate in the study. The referral approach was positive in Germany (six respondents), but resulted in only single completed interviews in Brazil and South Africa and no responses from the UK. The final sample included three interviews each from China, India, South Korea, and Turkey, six interviews in Germany, and nine in the USA[2]. Because the low response made it impossible to assess saturation, our data analysis excludes transcripts from Brazil, South Africa, and the UK. Table I provides each respondent firm’s nationality, industry, employee size, and supply chain classification. To help insure trustworthiness of the data collection (see Table I), we restricted the firmographic data heavily to ensure confidentiality. Qualitative interview questions and analysis The native category approach allowed us to dig deeply into managers’ unobservable and subjective perceptions, while using a naive line of inquiry in order to avoid leading questions that could impact interviewer expectations and answers (Harris, 2000). This approach also allowed us to ask very basic questions in a dynamic way. Table II presents an example of the native questionnaire tool, and the specific questions are provided in the Appendix. Most interviews lasted between 30 and 70 minutes, depending on response detail and complexity. We did not record five of the interviews because of company policies. When recording was not available, we used dual note takers and repetition techniques to ensure accuracy. We conducted all interviews in English with the exception of the South Korean ones. English impeded interview completion with South Korean respondents, so these were conducted in Korean and then translated to English for analysis. 713 Global exploration of Big Data Downloaded by Huazhong University of Science and Technology At 22:37 29 November 2016 (PT)
