    The current market conditions have forced Lean Six Sigma (LSS) upon businesses as one of the must-have practices. The practices have been credited with enhancing the efficiency of the operational and functional processes of enterprises from production to marketing, from personnel management to finance, all the while helping them augment their growth and profitability. LSS has the customer as its main focus and works to create added value for businesses through cost reduction and waste prevention hence can be considered as a process improvement practice. One priority area of improvement in most organizations is the assessment of Critical Business Processes (CBPs) as key processes in the success of businesses that must be tackled in line with the objectives of the businesses due to their extensive impact on customer satisfaction. For this purpose, this study evaluates and ranks the CBPs, and then select the most ideal CBP in food companies with corporate identity in Istanbul following the LSS success factors. Hence, the components attained from the literature are assessed using the suggested “q-ROF CRITIC-ARAS” method which is based on CRiteria Importance Through Intercriteria Correlation (CRITIC), Additive Ratio Assessment (ARAS) techniques and q-Rung Orthopair Fuzzy Sets (q-ROFSs). The findings demonstrate that the most important criterion for LSS success in food businesses is “Top Management and Support”, while “Education and Culture” is the least important. Furthermore, “Enlightenment Approach” is found to be the most ideal CBP based on LSS success factors

    Determining the importance level of effective criteria in the health information system selection via spherical fuzzy DEMATEL method
    (Springer, 2023) Aytekin, Ahmet; Koca, Gözde; Okoth, Basil Oluch; Karamaşa, Çağlar
    The dynamic structure of the health sector entails its integration with new technologies that transform every aspect of life. According to the developments in computer and communication technologies, health information systems have quickly been used in health institutions. On the other hand, with the spread of health information systems, problems were encountered in ensuring inter-institutional standards and quality. At this point, the selection of health information systems that are compatible with national and international health systems and that will meet the current and future needs of health institutions have gained importance. Purpose of this study is to determine the effective criteria in the selection of health information systems and the importance levels of these criteria. The criteria determined by scanning the literature were reduced to eight (security, cost, system quality and technical support, design, statistical information delivery, decision support system inclusion, accessibility, integration with external systems and subsystem inclusivity) by using the Delphi method with expert opinions. The spherical fuzzy DEMATEL method was applied to determine the importance levels of the criteria. The study will provide important novelties in terms of using the Delphi method at the point of determining the criteria and considering fuzziness and the interaction between the criteria.
