Yayın An analytic approach to assessing organizational citizenship behavior(Elsevier, 2017) Arda, Özlem Ayaz; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study examines the organizational citizenship behavior (OCB) of employees by designing and developing an analytic network process (ANP) methodology. The viability of the proposed methodology is demonstrated via the sales representatives of Beko, a brand name controlled by Koç Group. We first develop a conceptual framework based on qualitative research methods – in-depth interviews and focus group sessions. We employ the principles of ANP methodology to examine and discover the inter-relationships among the OCBs. This process results in a descriptive model that encapsulates the findings from both qualitative and analytics methods. Necessity, altruism, departmental, compliance, and independence are the underlying dimensions of OCBs found to be the most influential/important. The key novelty of this study resides in designing and developing a prescriptive analytics (i.e. ANP) methodology to evaluate the OCBs, which is rare in the area of organizational behavior (a managerial field of study that have been dominated by traditional statistical methods), and thus serves as a useful contribution/augmentation to the business/managerial research methods, and also extends the reach/coverage of analytics-based decision support systems research and practice into a new direction.Yayın An ANP and fuzzy TOPSIS-based SWOT analysis for Turkey's energy planning(Elsevier, 2018) Ervural, Beyzanur Çayır; Zaim, Selim; Demirel, Ömer Fahrettin; Aydın, Zeynep; Delen, Dursun; Zaim, Selim; Demirel, Ömer Fahrettin; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüEnergy planning involves a perpetual process of reevaluating alternative energy strategies. Authorities responsible for energy planning and management have to adjust their strategies according to new and improved alternative solutions based on the sustainability criteria. In this study, we propose an integrated hybrid methodology for the analysis of Turkey’s energy sector using Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, Analytic Network Process (ANP) process, and weighted fuzzy Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) to formulate and holistically analyze the energy strategy alternatives and priorities. The methodology proposed in this study allowed identifying the relevant criteria and sub-criteria using a SWOT analysis. Then, ANP approach, which is one of the popular multi-criteria decision making (MCDM) methods, is employed to determine the weights of each SWOT factors and sub-factors. Finally, fuzzy TOPSIS methodology is conducted to prioritize alternative energy strategies. We discuss the obtained results for the development of long-range alternative energy strategies. The results showed that turning the country into an energy hub and an energy terminal by effectively using the geo-strategic position within the framework of the regional cooperation is the most important priority. On the other hand, using the nuclear energy technologies within the energy supply strategies found to be the least favored priority.Yayın Assembly line balancing by using axiomatic design principles: An application from cooler manufacturing industry(Universidad Politecnica de Valencia, 2020) Yılmaz, Ömer Faruk; Demirel, Ömer Fahrettin; Zaim, Selim; Zaim, Selim; Demirel, Ömer Fahrettin; Yönetim Bilimleri Fakültesi, İşletme BölümüThe philosophy of production without waste is the fundamental belief behind lean manufacturing that should be adopted by enterprises. One of the waste elimination methods is assembly line balancing for lean manufacturing, i.e. Yamazumi. The assembly line balancing is to assign tasks to the workstations by minimizing the number of workstations to the required values. There should be no workstation with the excessively high or low workload, and all workstations must ideally work with balanced workloads. Accordingly, in this study, the axiomatic design method is applied for assembly line balancing in order to achieve maximum output with the installed capacity. In order to achieve this aim, all improvement opportunities are defined and utilized as an output of the study. Computational results indicate that the proposed method is effective to reduce operators’ idle time by 12%, imbalance workload between workstations by 38%, and the total number of workers by 12%. As a result of these improvements, the production volume is increased by 23%.Yayın Assessing the supply chain performance: A causal analysis(Springer US, 2019) Bayraktar, Erkan; Sarı, Kazım; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüMeasuring the performance-related factors of a unit within a supply-chain is a challenging problem, mainly because of the complex interactions among the members governed by the supply chain strategy employed. Synergistic use of discrete-event simulation and structural equation modeling allows researchers and practitioners to analyze causal relationships between order-fulfillment characteristics of a supply-chain and retailers’ performance metrics. In this study, we model, simulate, and analyze a two-level supply-chain with seasonal linear demand, and using the information therein, develop a causal model to measure the links/relationships among the order-fulfillment factors and the retailer’s performance. According to the findings, of all the order-fulfillment characteristics of a supply-chain, the forecast inaccuracy was found to be the most important in mitigating the bullwhip effect. Concerning the total inventory cost and fill-rate as performance indicators of retailers, the desired service level had the highest priority, followed by the lead-time and forecast inaccuracy, respectively. To reduce the total inventory cost, the bullwhip effect seems to have the lowest priority for the retailers, as it does not appear to have a significant impact on the fill rate. Although seasonality (to some extent) influences the retailer’s performance, it does not seem to have a significant impact on the ranking of the factors affecting retailers’ supply-chain performance; except for the case where the backorder cost is overestimated.Yayın Big data analytics capabilities and firm performance: An integrated MCDM approach(Elsevier, 2020) Yasmin, Mariam; Tatoğlu, Ekrem; Kılıç, Hüseyin Selçuk; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study explores the interdependence of big data analytics (BDA) capabilities and the impact of these capabilities on firm performance using an integrated multicriteria decision-making (MCDM) methodology. Drawing on a rich data set obtained from selected case study firms in Pakistan, three MCDM tools, namely, intuitionistic fuzzy decision-making trial and evolution laboratory (IF-DEMATEL), analytic network process (ANP), and simple additive weighting (SAW), are employed to assess the relative importance of BDA capabilities and the relationship of these capabilities with the firm performance. The results show that BDA capabilities are interdependent, and infrastructure capabilities are the highest-ranked among all, followed by management and human resource capabilities, respectively. The SAW results indicate an association between BDA capabilities and firm performance. Moreover, BDA capabilities are more strongly related to operational performance than to market performance.Yayın Building higher value-added firm practices in challenging contexts: Formal networks and talent management in Turkey(SAGE Publications, 2024) Demirbağ, Mehmet; Tatoğlu, Ekrem; Wood, Geoffrey; Glaister, Alison J.; Zaim, Selim; Nair, Smitha R.; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüWhere do high-impact human resources management practices thrive, and how do they make a difference in environments with limited institutional support? This study delves into the realm of talent management (TM) in Turkey, where institutional coverage is incomplete and unstable. Drawing on survey data, we explore the conditions under which TM succeeds, supplementing previous research on internal networks by examining the impact of external networks that encompass the entire firm. We find that when firms have closer ties with customers, suppliers and competitors (and hence, the basis for formal network tie building), TM is more prevalent and more likely to be successful. While conventional wisdom in comparative institutional literature suggests that such dense ties might be less effective in emerging markets owing to the absence of advanced complementarities found in mature economies, our study challenges these assumptions. In the eyes of managers, TM is not merely a tool to overcome disadvantages; it is perceived as a source of opportunities. This prompts a critical question: what specific advantages does the emerging economy system confer on firms embracing TM? Our study seeks to unravel these dynamics and contribute to a deeper understanding of the interplay between institutional contexts and TM.Yayın Business analytics and firm performance: The mediating role of business process performance(Elsevier, 2019) Aydıner, Arafat Salih; Tatoğlu, Ekrem; Bayraktar, Erkan; Zaim, Selim; Delen, Dursun; Tatoğlu, Ekrem; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüDue to the rapidly increasing popularity of business analytics (BA), investigation of the antecedents/determinants of the adoption of BA and the subsequent impact of the same to the firm performance has become an important research topic. Drawing on the fundamentals of the resource-based view (RBV), this study proposes a model that examines the effects of the BA adoption on business process performance (BPER) and the mediating role that BPER plays in the relationship between the adoption of BA and firm performance (FP). Based on the data collected from 204 medium- to high-level business executives in various industries, the results of this empirical study indicate that the adoption of BA positively influences BPER. There is also positive relationship between BPER and FP. Finally, the results show that BPER fully mediates the relationship between BA adoption and FP.Yayın Corporate governance and firm performance in emerging markets: Evidence from Turkey(Elsevier, 2019) Çiftçi, İlhan; Tatoğlu, Ekrem; Wood, Geoffrey; Demirbağ, Mehmet; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis is a study of the relationship between context, internal corporate governance and firm performance, looking at the case of Turkey, an exemplar of family capitalism. We found more concentrated ownership, often in the hands of families, led to firms performing better; concentrated ownership means that controlling families bear more of the risks of poor performance. Less predictably, given that the institutional environment is so well attuned to family ownership, we found that mechanisms that accord room for a greater range of voices and interests within and beyond families – larger boards and foreign ownership stakes – seem to also make for positive performance effects. We also noted that increase in cross ownership did not influence market performance, but was negatively associated with accounting performance. Conversely, we found that a higher proportion of family members on boards had no discernable effect on performance. Our findings provide further insights on the relationship between the type of institutions encountered in many emerging markets, internal corporate governance configurations and firm performance.Yayın ESIB’s antecedents: An analytic hierarchy process application in the manufacturing industry in Albania(MDPI, 2023) Malaj, Ardita; Zaim, Selim; Bayyurt, Nizamettin; Tarım, Merve; Zaim, Selim; Lisansüstü Eğitim Enstitüsü, İşletme Ana Bilim DalıThis study examined factors that might motivate employees to engage in social innovation. The objectives of this study were to identify the relative importance of factors that impact Employee Social Intrapreneurial Behavior (ESIB) in the manufacturing sector in Albania using an AHP approach and to select the best practice that can improve Employee Social Intrapreneurial Behavior (ESIB) on a company basis in the same sector by merging a linguistic method with the AHP approach. A questionnaire was designed to collect expert viewpoints. A standardized AHP scale ranging from 1 to 9 was used in the questionnaire. Fifteen managers and experts from four important manufacturing companies in Albania (Everest Shpk., Kamëz, Albania; Lufra Shpk., Lushnje, Albania; Ajka Shpk., Lushnje, Albania and F&M Shpk., Tirane, Albania) were contacted, and eleven of them expressed an interest in engaging in our study by ranking the importance of various criteria and sub-criteria. The findings suggest that the sub-components of the internal factor, such as superior relationship quality and expected image gains, have a combined importance of 50% in the local weights in the Albanian context. The two sub-components mentioned above remain significant in the analysis of global weights, accounting for 41% of global influence...Yayın How does external knowledge sourcing affect business performance in large-scale firms? The mediating role of open technology strategies(IEEE, 2021) Avunduk, Zehra Binnur; Kazan, Halim; Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis article examines the mediating impact of open technology strategies (OTS) on the link between three types of external knowledge sources (i.e., scientific, institutional, and indirect partners) and business performance (BP). Structural equation modeling is conducted in order to test the research model based on a survey of 241 companies drawn from the database of Turkey’s largest 500 manufacturing companies. The study’s findings indicate that the implementation of OTS mediates the relationships between external knowledge sourcing (EKS) from scientific partners and indirect partners with BP. However, no support is found for the mediation effect of OTS on the link between EKS from institutional partners and BP. This article extends the innovation literature by empirically investigating open innovation in large-scale companies in emerging country settings.Yayın Howdo organizational career management activities influence employees’ career outcomes? The mediating role of career capital(Emerald Group Publishing, 2023) Yıldız, Didem; Bozbura, F. Tunç; Tatoğlu, Ekrem; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüPurpose – This study addresses a critical research gap by examining the pivotal role of organizational career management (OCM) in shaping employees’ career outcomes while also investigating the mediating influence of career capital in this relationship. This study aims to shed light on the importance of OCM as a strategic approach for enhancing employees’ career trajectories, filling a significant gap in the existing literature. Design/methodology/approach – Using a cross-sectional research design, primary data were gathered through a structured questionnaire administered to a diverse sample of 426 Turkish working adults representing various organizations. The study uses structural equation modelling with AMOS to analyse the direct and indirect relationships within the proposed research model. Findings – The study findings underscore the essential connection between OCM and employees’ career outcomes, revealing its positive influence on subjective career success, employability and innovative work behaviour. Moreover, career capital emerges as a critical intermediary mechanism that mediates the impact of OCM on these career outcomes, further highlighting the strategic significance of OCM practices. Research limitations/implications – It is important to note that this study relies on self-report surveys to gauge employees’ perceptions about their career outcomes and OCM. Additionally, the study data are confined to the Turkish context, which may influence the generalizability of the findings to other contexts. Practical implications – Organizations can bolster career outcomes through strategic investment in OCM. Industries can customize approaches, leveraging insights to optimize workforce potential. Policymakers should integrate career development principles, cultivating a culture of perpetual learning, thus fortifying organizational resilience and fostering sustainable success. Originality/value – This study adds substantial value to the current body of knowledge by investigating the mediating role of career capital in the relationship between OCM and individual career outcomes, particularly within the context of emerging economies like Turkey. The study’s comprehensive approach to understanding careers from both individual and organizational perspectives contributes to a more nuanced and holistic understanding of career dynamics.Yayın Information system capabilities and firm performance: Opening the black box through decision-making performance and business-process performance(Elsevier, 2019) Aydıner, Arafat Salih; Tatoğlu, Ekrem; Bayraktar, Erkan; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study contributes to the extant literature on information management by investigating the interrelationships between information systems (IS)-related capabilities and their effects on firm performance. Using the resource-based view (RBV), a set of hypotheses is formulated to examine these links, considering the role that may be played by decision-making performance and business-process performance as mediating variables. Structural equation modeling (SEM) has been applied to a sample of 204 firms in Turkey. The test results obtained confirm the proposed serially mediating model according to which decision-making performance and business-process performance play a critical mediating role in the human resource and administrative-related IS capabilities, and firm-performance relationships. No support, however, has been found concerning the serial mediation effect between infrastructure-related IS capabilities and firm performance.Yayın An integrated approach for lean production using simulation and data envelopment analysis(Springer, 2021) Buyuksaatci Kiris, Sinem; Eryarsoy, Enes; Zaim, Selim; Delen, Dursun; Zaim, Selim; Delen, Dursun; Yönetim Bilimleri Fakültesi, İşletme BölümüAccording to the extant literature, improving the leanness of a production system boosts a company’s productivity and competitiveness. However, such an endeavor usually involves managing multiple, potentially conflicting objectives. This study proposes a framework that analyzes lean production methods using simulation and data envelopment analysis (DEA) to accommodate the underlying multi-objective decision-making problem. The proposed framework can help identify the most efficient solution alternative by (i) considering the most common lean production methods for assembly line balancing, such as single minute exchange of dies (SMED) and multi-machine set-up reduction (MMSUR), (ii) creating and simulating various alternative assembly line configuration options via discrete-event simulation modeling, and (iii) formulating and applying DEA to identify the best alternative assembly system configuration for the multi-objective decision making. In this study, we demonstrate the viability and superiority of the proposed framework with an application case on an automotive spare parts production system. The results show that the suggested framework substantially improves the existing system by increasing efficiency while concurrently decreasing work-in-process (WIP).Yayın The effect of organizational culture, supplier trust and information sharing on supply chain viability(Springer, 2024) Acar, Mehmet Fatih; Torgalöz, Alev Özer; Eryarsoy, Enes; Zaim, Selim; Ruel, Salomée; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study investigates the impact of intangible resources such as adhocracy culture (ADC), information sharing with suppliers (IS), and supplier trust (ST) on supply chain viability (SCV) under high inflation environment. To do this, a conceptual model is developed to analyze the associations between these suggested variables. Using on a cross-sectional survey, data are collected from 216 supply chain (SC) and production practitioners based in Türkiye who are medium- to senior-level managers. To analyze our theoretical model, we processed our data and model using lavaan package in R. The results show a significant relationship between ADC and SCV. Additionally, both of IS and ST capabilities are found to have a strong mediating effect on the ADC and SCV relationship. The results of this study will provide insight for managers and researchers to prevent the negative effects of SC disruptions due to the high inflation or other type of stress tests. Extant research has investigated the SCV with different crises like COVID-19 pandemic however, the study is the first research that examines SCV under high inflation stress test. Moreover, ADC, IS and ST have not widely appeared in SCV literature. In this regard, this research also contributes to the ongoing efforts of investigating the antecedents of SCV.Yayın Toward a holistic understanding of sustainability in corporations: Resource-based view of sustainable supply chain management(Emerald Publishing, 2021) Ayaz Arda, Özlem; Montabon, Frank; Tatoğlu, Ekrem; Gölgeci, İsmail; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüPurpose While the three interconnected aspects of the triple bottom line -environmental, social and economic sustainability- are well-established, these aspects have insufficiently been addressed together in the supply chain management literature. Thus, the purpose of this paper is to examine whether environmental and social performance mediates the relationship between environmental management practices and operational performance and whether operational performance mediates the relationship between environmental and social performance and financial performance. Design/methodology/approach Drawing on a data set of 208 firms operating in a wide range of manufacturing industries, the authors test the hypotheses using structural equation modeling. The research context for the study is Turkey, an important emerging market and one of the nexuses of European and Asian supply chains. Findings The findings indicate that all three aspects of sustainability have mutually supportive relationships as demonstrated by positive mediating mechanisms between environmental management practices and operational performance and between environmental and social performance and financial performance. The mediation results correspond with the resource-based view. They indicate that building up capabilities and resources in the form of environmental management practices supports three areas of the triple bottom line and boosts firms' financial performance. Originality/value Research on sustainability is well-established, yet supply chain management research has, thus, far paid insufficient attention to all three aspects. This paper, thus, sets itself apart by explicitly considering all three aspects of sustainability and contributes to understanding how they relate to one another.Yayın Unlocking the relationships between strategic planning, leadership and technology transfer competence: The mediating role of strategic quality management(Emerald Publishing, 2022) Sönmeztürk Bolatan, Gülin İdil; Gölgeci, İsmail; Arslan, Ahmad; Tatoğlu, Ekrem; Zaim, Selim; Gözlü, Sıtkı; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüPurpose This study aims to investigate the relationships between firms' strategic planning (SP), leadership and technology transfer competence (TTC) by specifically incorporating the mediating role of strategic quality management (SQM). Design/methodology/approach This study performs structural equation modeling using AMOS on survey data collected from 200 Turkish firms operating in multiple industries and sectors. Findings This study finds that leadership in Turkish firms operating in multiple sectors is positively associated with SQM. This study further finds that SQM positively influences Turkish firms' TTC and mediates the roles of SP and leadership in TTC. Research limitations/implications A key research implication from this study relates to the mediating role of SQM in TTC in an emerging economy context. This study highlights that SP and leadership can play an essential role in TTC through the mediating mechanism of SQM. Consequently, SQM emerges as a crucial linking pin in conveying the impact of quality management practices on technology transfer in emerging markets. Practical implications An essential managerial implication of this study relates to the critical roles of leadership, SP and SQM in TTC. For the managers of firms operating in a relatively uncertain emerging context such as Turkey, it is essential to adopt a supportive and empowering leadership style, where open communication and innovative activities are viewed positively and SQM is adopted holistically. Also, SP should be streamlined throughout the firm and followed by SQM to support TTC. Originality/value This paper links the technology (and knowledge) management and the strategy and leadership literature streams by focusing on the mechanisms of technology transfer and delving into the linkages between SQM, leadership, SP and TTC. It specifically presents SP and leadership as precursors to SQM in their joint influence on TTC. Accordingly, this research bridges technology, strategy and leadership research and provides a broader picture of technology transfer that encompasses the joint role of different processes in firms' TTC.Yayın Unveiling the drivers of global logistics efficiency: Insights from cross-country analysis(MDPI, 2024) Bayraktar, Erkan; Eryarsoy, Enes; Kosanoglu, Fuat; Acar, Mehmet Fatih; Zaim, Selim; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüThis study presents a novel approach to assess countries’ relative logistics performance differentials and identifies the underlying drivers using a data envelopment analysis (DEA) approach. The findings offer strategic insights and provide nations with valuable guidance in navigating the dynamic landscape of global logistics competitiveness. Recognizing the pivotal role of logistics in fostering economic activity and contributing to sustainability, we utilize the Logistics Performance Index (LPI) within the DEA model to gauge efficiencies at the country level and scrutinize influencing factors. Our findings indicate that international shipment practices in the last decade, as well as tracking and tracing recently, no longer contribute to the competitiveness of the countries, despite their potential for improvement. The overall change in logistics efficiency during the last decade remained relatively marginal, primarily driven by the frontier-shift effect. However, notable disparities among the country performance groups, particularly in adopting technological advancements, are manifested in the frontier-shift effect. Countries with lower logistics performance should prioritize addressing structural challenges related to customs, infrastructure, quality of logistics services, and timeliness. Medium-performance countries, while benefiting from a focus on customs, tracking and tracing, and timeliness in the early 2010s, are advised to align their efforts with high-performance countries by emphasizing managerial aspects in recent times.Yayın Using machine learning tools for forecasting natural gas consumption in the province of Istanbul(Elsevier, 2019) Beyca, Ömer Faruk; Ervural, Beyzanur Çayır; Tatoğlu, Ekrem; Özuyar, Pınar Gökçin; Zaim, Selim; Tatoğlu, Ekrem; Zaim, Selim; Yönetim Bilimleri Fakültesi, İşletme BölümüCommensurate with unprecedented increases in energy demand, awell-constructed forecastingmodel is vital to managing energy policies effectively by providing energy diversity and energy requirements that adapt to the dynamic structure of the country. In this study, we employ three alternative popular machine learning tools for rigorous projection of natural gas consumption in the province of Istanbul, Turkey's largest natural gas-consuming mega-city. These tools include multiple linear regression (MLR), an artificial neural network approach (ANN) and support vector regression (SVR). The results indicate that the SVR is much superior to ANN technique, providing more reliable and accurate results in terms of lower prediction errors for time series forecasting of natural gas consumption. This study could well serve a useful benchmarking study for many emerging countries due to the data structure, consumption frequency, and consumption behavior of consumers in various time-periods.
