Theory of Constraints (TOC) is a management philosophy which is focused on the weakest ring(s) in the chain to improve the performance of systems. Companies, whether they are in the production or service sector should be more focused on understanding their own structure in terms of processes to survive in a global competition. In this situation, TOC becomes an important problem structuring and solving methodology which changes the way of thinking of managers. Since the TOC first put forth by Goldratt (1984) in his novel The Goal, the theory has drawn wide attention from practitioners and academic researchers. This study provides a review of the TOC evolution literature by its five era; the optimized product technology era, the goal era, the haystack syndrome era, the it's not luck era and the critical chain era. Our search at historical background and basic concepts of TOC aims to see how this philosophy evolves through time and how the main point of TOC researches changes

Easy access to the Internet, smartphones, and mobile-based banking change customer shopping intentions. As a crucial component of financial technology (Fintech), mobile wallets enable customers to shop via smartphones. Mobile wallets present a cashless transactional method, cost-efficient services, and traceable options that improve sustainability in payment services. Over the last decade, mobile wallet services have evolved and attracted considerable attention from customers and companies. Due to the need for a comprehensive mobile wallet literature survey, this article aims at filling this research gap by covering articles published between 2012 and 2022 over the Scopus, Web of Science, and Science Direct databases. A clear filtering policy was conducted to observe the related article topics. Thus, 128 articles that met the inclusion and exclusion criteria were analyzed. Moreover, the articles were initially classified into three main groups, which was performed via scanning and categorizing all studies in the last ten years from different databases. In addition, the literature was systematically reviewed, providing a better understanding of mobile wallets and contributing to the literature by researching how this service can be improved for payment services with a focus on sustainability. The conducted literature review revealed that mobile wallets could be promoted in terms of environmental traceability, customer lifetime value, and security.

Fresh fruit and vegetables are crucial for human health. Their fibrous structure and high nutritional value are essential for people’s well-being. This study aims to provide a review of the current state of knowledge and practices regarding fresh fruit and vegetable supply chains (FFVSC). The reviewed papers are divided into categories according to their findings, research purposes, tools and messages used. Our objective is to guide both academics and practitioners by pointing out significant streams of research with respect to these categories. For a better understanding, these subgroups are essentially based on their common research purpose, and the tools and methods they adopted are explained. Therefore, this study sheds light on research related to FFVSCs for those who are new to this area or planning to conduct in-depth research on directions suggested by studies in this area. The related literature was classified into eight categories: namely, (1) value chain indicators of FFVSCs, (2) food-related problems/postharvest losses along FFVSCs, (3) roles of parties involved in the FFV value chain, (4) review papers, (5) technological trends in FFVSCs, (6) packaging issues of FFVSCs, (7) logistics solutions of FFVSCs, and (8) sustainable FFVSCs. Details on the tools and methods employed in these studies are summarized in Appendix B. To the best of the authors’ knowledge, the related literature lacks a comprehensive review that investigates different aspects of FFVVCs in detail. Thus, this study contributes towards a better understanding of the related literature and can be used as a guide for future studies.

Increased competition and globalization compels most organizations to become innovative and adopt change approaches. Business Process Reengineering is one of the most popular change management approaches that can bring incredible solutions to corporations. BPR has arisen as a solution for companies to improve their performances; elevate their efficiencies and gain a competitive advantage in this everlastingly developing and changing world. Even though there have been successful and unsuccessful cases stated in the literature, BPR has been touted as a vital management tool in order to achieve dramatic improvements and organizational competitiveness, if it is implemented properly and carefully. In this context; with this study, we analyze Business Process Reengineering as today’s prominent management trend for organizational change, examine an reengineering project that has been undertaken in a multinational electronics and electrical equipment company, make suggestions for the areas that can be improved, and finally present survey results of employees` point of view regarding this project in their company.
