A New Holistic Conceptual Framework for Leanness Assessment
(RAM ARTI PUBL, 2020) Cansu Tayaksi; Muhittin Sagnak; Yigit Kazancoglu; Tayaksi, Cansu; Sagnak, Muhittin; Kazancoglu, Yigit
Lean principles aiming at eliminating waste and increasing efficiency at a company take their roots from the initiatives of Taiichi Ohno. After the implementation of the principles at the Toyota Motor Company for the first time businesses started to discover the benefits of lean implementation in terms of efficiency increase. As the adaptation of lean into the manufacturing sector is continuing the necessity of assessing the level of leanness at the firm-level maintains its importance. Taking systems approach as a basis the lean performance of an organization should be assessed as a whole. Therefore we propose a holistic leanness assessment framework which encapsulates various dimensions of the leanness assessment and we identify the importance and causal relationships between the sub-criteria. In order to identify the importance and causal relationships between the sub-criteria we used fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL). Our findings show that the most influencing factor in the cause group is 'technology and product design' which indicates the companies' necessity to focus on Industry 4.0 during their operations. The results also illustrate that the most influenced factor in the effect group is 'productivity' in which companies can investigate strategic competitive advantages. The design of a holistic framework and the implementation of fuzzy DEMATEL offers a way to identify the importance and the causal relationships between the sub-criteria. With the help of a case study conducted in the plastics industry of Turkey we offer managerial implications that could help managers to implement the proposed structural leanness assessment framework.

As a business function similar developments has been observed in operations management field. One of the new Technologies is Cloud Manufacturing system which has been developed under Cloud Computing applications. Aim of this new model is providing benefits like lower costs and higher performances or increasing the market entry speed for businesses. In this study conceptual structure of Cloud Manufacturing and the advantages has been investigated. Lastly a business model has been presented that explains the logic flow and can be used as a road map for businesses.

Quality function deployment application for improving quality of education in business schools
(ROUTLEDGE JOURNALS TAYLOR & FRANCIS LTD, 2017) Muhittin Sagnak; Nesrin Ada; Yigit Kazancoglu; Cansu Tayaksi; Sagnak, Muhittin; Kazancoglu, Yigit; Tayaksi, Cansu; Ada, Nesrin
There is an increasing competition between universities globally to attract students. At this point to compete it is imperative for the universities to improve the quality of education provided for their stakeholders including students parents and employers. For improving the quality of education first of all the universities should make efforts to understand stakeholder expectations by analyzing their needs and wants. For this purpose the authors incorporated the quality function deployment technique with fuzzy analytical network process. Due to the vagueness present in the evaluation of relative importance of the criteria for higher education fuzzy set theory is integrated.

The financial impacts of information systems security breaches on publicly traded companies: reactions of different sectors
(Emerald Group Holdings Ltd., 2022) Cansu Tayaksi; Erhan Ada; Yigit Kazancoglu; Muhittin Saǧnak; Tayaksi, Cansu; Ada, Erhan; Kazancoglu, Yigit; Sagnak, Muhittin
Purpose: Today information systems and technology provides a wide set of tools for companies to increase the efficiency of their businesses. Although technology offers many benefits to businesses it also brings risks as the information systems security breaches. Security breaches and their financial impact is a constant concern of the researchers and practitioners. This paper explores information systems breaches and their financial impacts on the publicly traded companies in different sectors. Design/methodology/approach: After a comprehensive data collection process data from 192 events are analyzed by employing Event Study Methodology and a comparison of the results between the four highly affected sectors (Consumer Goods Technology Financial and Communications) is presented. The abnormal returns on the prices of stocks after the events are calculated with the Market Model. Also the results of the Market Adjusted Model and Mean Adjusted Model are presented to support the results. Findings: While information systems security breaches have a significant negative impact on the Financials and the Technology sectors for all the event windows in the study ([−5 0] [−5 1] [−5 5] and [−5 10]) the significant negative impact is observed only on the [−5 5] and [−5 10] event windows for the Consumer Goods sector. No significant negative impact is observed in the Communications sector in fact the cumulative abnormal returns are positive for this sector. Originality/value: The contribution of this paper to provide evidence about the financial impacts of the information systems breaches for businesses in different sectors. While there are studies that have previously focused on the information systems breaches and their financial impacts on businesses to the best of our knowledge this is the first study that compares this effect between the four highly impacted sectors. With a relatively larger sample size and broader event windows than the past studies in the literature statistical evidence is provided to managers to justify their investments in information security and build preventive measures to secure the market value of their firms. © 2022 Elsevier B.V.
